The attributes that apply to bacteria but not humans or viruses are: (b) have chromosomes in a nucleus, (c) grow by mitosis, (g) can't encode their own cells, (h) can be penicillin-resistant, (j) grow by binary fission.

Bacteria are single-celled organisms that possess distinct characteristics that differentiate them from humans and viruses. They have a prokaryotic cell structure, meaning they lack a nucleus and membrane-bound organelles. Instead, their genetic material, including chromosomes, is present in the cytoplasm.

Bacteria grow by a process called binary fission, where a single bacterial cell divides into two identical daughter cells. This is in contrast to humans and viruses, which have different modes of reproduction. Bacteria can also develop resistance to antibiotics like penicillin, allowing them to survive and multiply even in the presence of these drugs.

Overall, bacteria exhibit unique attributes that distinguish them from humans and viruses, including their cellular structure, growth and reproduction methods, ability to develop resistance, and reliance on external sources for survival.

The most common type of alternative splicing in animals is skipping cassette exons. Option C is correct.

Alternative splicing is a process which occurs during gene expression, where different combinations of exons (coding regions) within a gene can be included or excluded from the final mRNA transcript. This process allows a single gene to generate multiple protein isoforms with different functions or properties.

Skipping cassette exons, also known as exon skipping or cassette exon exclusion, is the most prevalent type of alternative splicing in animals. In this type of splicing, one or more exons are spliced out of the mRNA transcript, resulting in the exclusion of specific protein-coding regions. This can lead to the production of different protein isoforms with varying functions or structural properties.

Hence, C. is the correct option.

Answer:

What is the vascular system? The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter

Answer:

It was formed around 4.5 billion years ago when something the size of mars smashed into the Earth, which made matter fly into orbit.

Plants eliminate waste products generated during photosynthesis through a process called transpiration. The primary waste product of photosynthesis is oxygen, and it is removed from the leaf through small openings called stomata.

During photosynthesis, plants absorb carbon dioxide and release oxygen as a byproduct. Oxygen molecules diffuse out of the leaf cells and accumulate in the intercellular spaces within the leaf.

From there, oxygen moves into the stomata, which are tiny pores on the surface of leaves. Stomata are open and close to regulate gas exchange and water loss. When the stomata are open, oxygen is released into the surrounding atmosphere through diffusion, effectively removing it as a waste product.

Transpiration, the process by which water vapor evaporates from the leaf's surface, also helps in the removal of waste products. As water evaporates from the leaf through the stomata, it carries away any dissolved gases, including oxygen.

This process ensures that waste products of photosynthesis are efficiently eliminated from the leaf and allows for the exchange of gases necessary for plant respiration.

Role of Primers in PCR: 1) polymerize free nucleotides to form new DNA strands. 2) provide energy for DNA polymerization reactions. 3) provide 3' end for DNA polymerase.

PCR primers are short single-stranded DNA fragments that are complementary to and flank the target region. They act as starting points for new strands. The enzyme polymerase can only add DNA bases to double strand of DNA. Only when the primer binds can the polymerase enzyme bind and start building a new complementary strand of DNA from the loose DNA bases.  

Careful design of synthetic oligonucleotide primers is critical to the overall success of a PCR experiment. An ideally designed primer pair ensures efficiency and specificity of the amplification reaction, resulting in high yields of the desired amplicon.

Charles and Francis Darwin experimented on coleoptiles (the protective sheaths covering young shoot of grass) and exposed them to light. They concluded that the tip of coleoptiles is sensitive to light and gravity.

The tip is able to sense the direction of the light and gravity, thus making it easier for the plant to grow and orient itself in the right direction. When coleoptiles are exposed to light, the growth of the coleoptiles is inhibited on one side while stimulated on the other side.The Darwins established that coleoptiles can detect light from their tips through experiments on the growth of these coleoptiles.

They covered the tips of the coleoptiles, exposing them to light from one side and blocking light on the other side. The tip of the coleoptile that was exposed to light grew away from the light, while the side that was shielded from light didn't grow as fast.

The Darwins established that the growth of the coleoptiles was stimulated on the side opposite the light source, while the growth on the side of the light source was inhibited. This observation showed that the coleoptiles tip could sense the direction of the light and direct growth accordingly.

In conclusion, Charles and Francis Darwin established that the tip of coleoptiles is sensitive to light and gravity, and it can sense the direction of the light. This ability allows the coleoptiles to grow and orient themselves in the right direction, and thus be able to grow towards the light to continue their photosynthetic activities.

The cause of the color patterns in the sky is when light is diffracted from water droplets within the clouds, the amount of diffraction that occurs depends on the wavelength of the light, and shorter wavelengths are diffracted at a greater angle than longer ones which is therefore denoted as option D.

This is a term which is described as the process of light bending around an obstacle or spreading out after it moves through a small or tiny space.

We should also be aware that it  is dependent on the wavelength of the light such that those with a shorter wavelengths are usually diffracted at a greater angle than longer ones which is therefore the reason why the color pattern is observed in the sky and is therefore the reason why it was chosen as the correct answer.

Dolphin meat is more likely contaminated and contains higher levels of mercury than other species due to its position in the food chain and the process of biomagnification.

Biomagnification is the process by which the concentration of certain substances, such as pollutants or toxins, increases in organisms as they move up the food chain. Dolphins are apex predators, meaning they feed on other marine animals, many of which have already accumulated mercury in their bodies. As dolphins consume these contaminated animals, the concentration of mercury in their tissues increases. This can lead to bioaccumulation, which is the buildup of toxins in an organism over time and can result in negative health effects.

The hypothalamus contains specialized neurons that sense changes in the body's temperature. If blood temperature rises too high, specialized neurons in the hypothalamus of the brain sense the change.

These neurons signal other nerve centers, which in turn send signals to the blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. The body will then decrease the amount of heat generated and release it through sweating. This mechanism helps to maintain body temperature at normal levels.

The main answer is that specialized neurons in the hypothalamus signal other nerve centers to send signals to the blood vessels of the skin to dilate, increasing blood flow and releasing excess heat from the body.

As a conclusion, the body tries to maintain normal temperature levels through a process called thermoregulation.

The portions of the brain that contain respiratory centers and set the breathing rate are the medulla and pons. The answer is: (A)

The medulla and pons are the portions of the brain that contain respiratory centers and regulate the breathing rate. These regions are located in the brainstem, which is responsible for controlling various involuntary functions, including respiration.

The medulla oblongata, located at the base of the brainstem, contains the primary respiratory center. It receives input from chemoreceptors that monitor blood oxygen and carbon dioxide levels and adjusts the breathing rate accordingly. The medulla sets the basic rhythm and depth of breathing.

The pons, located above the medulla, contains the pontine respiratory group. It works in conjunction with the medulla to fine-tune the breathing pattern, coordinating the transition between inhalation and exhalation. The pons also receives input from higher brain centers and helps regulate the breathing rate based on factors such as emotions and physical activity.
