As a result of photosynthesis, oxygen gas is released into the atmosphere and used by people, animals, and other living things for respiration.

1) Photosynthesis - Plants manufacture oxygen and sugar-based energy through a process known as photosynthesis, which uses sunlight, water, and carbon dioxide.

There are three primary types of photosynthesis: C3, C4, and CAM (crassulacean acid metabolism). I had to memorise some of their pathways and mechanisms in college, but I'll focus on the advantages of each and what kinds of plants, forages, and weeds have specialised C3 and C4 photosynthesis.

2) Cellular respiration

In order to release energy in the form of ATP, sugar must be broken down in the presence of oxygen within the mitochondria of organisms (both animals and plants). This process is known as cellular respiration. As waste products, this procedure emits water and carbon dioxide. The process of cellular respiration can be carried out by mitochondria in plants.

The most accurate statement that explains the difference between heart cells and liver cells in terms of their production of the protein cardiac myosin is "Heart and liver cells express different genes."

In multicellular organisms, different cell types have specific functions and characteristics that are determined by the genes they express. Genes are segments of DNA that contain the instructions for producing specific proteins. Each cell type expresses a unique set of genes that enable them to carry out their specialized functions.

In the case of heart cells and liver cells, they have different gene expression profiles. Heart cells specifically express the genes responsible for producing cardiac myosin, a protein essential for the contraction of the heart muscle. This allows the heart to effectively pump blood throughout the body.

On the other hand, liver cells do not express the genes for cardiac myosin production, as the liver has different functions unrelated to heart muscle contraction. The statement that heart cells contain different genes from liver cells is essentially expressing the same idea. Heart cells and liver cells have distinct gene expression patterns, leading to the production of different proteins and ultimately different cellular functions.

Both heart cells and liver cells utilize DNA as the genetic material that contains the genes responsible for protein production. RNA molecules are transcribed from DNA and play a crucial role in protein synthesis, but the distinction between heart and liver cells lies in the specific genes they express, not the reliance on different genetic materials.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Answer:

There are several ways in which negative human impact on the pH of Earth's oceans can be reduced. Here are two possible approaches:

Reducing carbon dioxide (CO2) emissions: The primary cause of ocean acidification, which lowers the pH of the oceans, is the increased absorption of CO2 from the atmosphere. To address this, it is crucial to reduce carbon dioxide emissions at their source. This can be achieved by transitioning to cleaner and renewable energy sources, promoting energy efficiency, and implementing policies to limit greenhouse gas emissions from industries, transportation, and power generation. By reducing CO2 emissions, we can slow down the rate of ocean acidification.

Promoting sustainable fishing and aquaculture practices: Overfishing and destructive fishing practices can disrupt marine ecosystems and contribute to the decline in ocean health. By promoting sustainable fishing practices, such as implementing fishing quotas, protecting marine reserves, and avoiding the capture of non-target species (bycatch), we can maintain the ecological balance of marine ecosystems. Additionally, supporting responsible and sustainable aquaculture practices that minimize environmental impacts and avoid the use of harmful chemicals can help reduce the negative human impact on ocean pH.

It's important to note that these are just two examples, and addressing ocean acidification requires a multi-faceted approach involving various stakeholders, including governments, industries, scientists, and individuals. Other measures, such as protecting coastal habitats, reducing pollution runoff, and raising awareness about the importance of ocean conservation, can also contribute to mitigating the negative human impact on ocean pH.

Answer: Pyruvate would increase, NADH would decrease, and intermembrane H+ would decrease as well.

Explanation:

Glycolysis would raise pyruvate, but the Krebs Cycle would not produce NADH, decreasing it. No protons (H+) will be pushed into the intermembrane gap, lowering its H+ content and raising its pH.

The tricarboxylic acid (TCA) cycle, commonly referred to as the Krebs cycle or the citric acid cycle, is the primary route that cells use in order to acquire energy and is an essential component of aerobic respiration. The cycle transforms the oxidative potential of acetyl coenzyme A (acetyl CoA) into the reductive potential of nicotinamide adenine dinucleotide (NADH).

The synthesis of ATP via the Krebs cycle is disrupted when arsenic is present because it prevents pyruvate from being converted into acetyl coenzyme A (acetyl-CoA). In addition to the effects described above, arsenic also prevents glucose uptake at the cellular level, as well as gluconeogenesis, the oxidation of fatty acids, and additional acetyl-CoA formation.

2. Alligators would be considered as a Quaternary consumer as they are in the top of the food chain, meaning that nothing else could prey upon them.

3. There are 5 factors in the Energy Pyramid: Producer, Primary Consumer, Secondary Consumer, Primary Consumer, Tertiary Consumer and Quaternary consumer. As producers are the first and main factors that receive energy from the sun, they would receive 100% of energy. This energy is decreased by 10% as it is consumed by more and more consumers. Therefore: Producer would receive 2500 units of energy, Primary Consumer would receive 250, Secondary Consumer would receive 250, Primary Consumer would receive 225, Tertiary Consumer would receive 202.5 and Quaternary consumer would receive 182.25 of energy.

You can refer to this video for further explanation: https://youtu.be/CReZd9OHEfs

Based on the word parts, the label for an alligator would be "tertiary consumer," and at the tertiary consumer level (alligator), there would be approximately 2.5 units of energy available from the original 2500 units of energy from the sun.

The energy pyramid represents the flow of energy in an ecosystem from the sun to the different levels of consumers. At the base of the pyramid are producers, such as plants, that use the energy from the sun to produce food through photosynthesis. The next level consists of primary consumers, such as herbivores, that eat the producers. The next level consists of secondary consumers, such as carnivores that eat the primary consumers, and so on. Each level of the pyramid represents a different trophic level in the food chain, and the energy available at each level decreases as we move up the pyramid. Here , Producer level: 2500 units, so Primary consumer level: 10% of 2500 units = 250 units Secondary consumer level: 10% of 250 units = 25 units; and tertiary consumer level (alligator): 10% of 25 units = 2.5 units.

Hence, based on the word parts, the label for an alligator would be "tertiary consumer," and at the tertiary consumer level (alligator), there would be approximately 2.5 units of energy available from the original 2500 units of energy from the sun.

What Is Sound

In physiology, sound is produced when an object’s vibrations move through a medium until they enter the human eardrum. In physics, sound is produced in the form of a pressure wave. When an object vibrates, it causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium. While the physiological definition includes a subject’s reception of sound, the physics definition recognizes that sound exists independently of an individual’s reception. You may recognize this section from our blog post, “What is a Sound Wave in Physics?” Keep reading for a more in-depth look at sound waves.

Answer:

Ans 1 - Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.

Ans 2- Music is a sound that produces a pleasing sensation. It is produced by nature, musical instruments, human voice, etc. Noise is an unwanted and unpleasant sound produced by horns of vehicles, by machines, etc.

Ans 3 - Humans have elastic ligaments called vocal cords attached to the bones in the throat. When air is passed over these cords, they vibrate and make sound. ... Marine mammals also make many sounds by vibrating elastic ligaments (vocal cords) in the larynx.

Ans 4 - The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. Amplitude is measured in decibels.

Ans 5 - The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived.

Ans 6 - about 20 Hz to 20 kHz

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

Ans 7 - Explaining the terms infrasound and ultrasound, used for vibrations that we cannot hear. ... Beyond what we can hear there is: Infrasound, where the rate of vibration is too low for us to hear. Ultrasound, where the rate of vibration is too high for us to hear.

Ans 8 - Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. ... The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone.

There is currently an imbalance of carbon in the atmosphere due to burning of fossil fuels, deforestation, and pollution and this causes global warming.

Burning of fossil fuels, changing the land use, and use of limestone to make concretes all are important for the transfer of significant quantities of carbon into the surrounding atmosphere. As a result, the amount of carbon dioxide gas in the atmosphere is rapidly rising and it is already greater than the concentration of carbon dioxide at any period of time in the last 3.6 million years.

By increasing the amount of the greenhouse gases such as carbon dioxide in the atmosphere, the Earth is becoming warmer with time. Carbon dioxide spends a long time, in the atmosphere before decomposition, so even if the people stopped adding carbon dioxide to the atmosphere now because, the Earth would continue to warm.

2. law of Segregation; meiosis I; in separate gametes.

Explanation:

Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:

1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent  

2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.

3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).
