Answer:

Oxygen and hydrogen ions are also formed from the splitting of water. To replace the electron in the reaction center, a molecule of water is split. This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.

The correct heading to which the given phrase is closely related is Calvin cycle (light-independent reactions of photosynthesis).

According to the definition of photosynthesis, it is the process through which certain microorganisms and green plants produce food when exposed to sunlight. When the organic molecule is in the presence of carbon dioxide, water, and sunlight, glucose is produced. The process by which oxygen is produced as a byproduct is called photosynthesis. An example of an oxidation-reduction reaction is photosynthesis. Water passes through oxidation whereas carbon dioxide goes through reduction.

The Kreb's cycle, often known as the citric acid cycle, is a critical phase of cellular respiration. The breakdown of acetyl coenzyme A (decarboxylated pyruvate) takes place in the mitochondrial matrix.

The fixation of carbon dioxide into sugar molecules occurs during the Calvin cycle, also known as the light-independent processes of photosynthesis. ATP and NADH are created as a result of the process, which occurs in the thylakoid membrane. In the absence of sunshine, the procedure takes place.

The photosynthesis process involves the transformation of light energy into chemical energy. Within thylakoids, the activity takes place in the presence of oxygen.

Ions must flow across the membrane during chemiosmosis. An electrochemical gradient is created as a result. The synthesis of ATP is driven by this electrochemical gradient.

Prokaryotes and eukaryotes engage in glycolysis, which involves the breakdown of glucose to produce energy. It is a crucial phase of the respiration process. Pyruvate, the byproduct of glycolysis, is added to a number of cycles to provide energy.

The correct answer is:

1: All living things, both animals and plants, breathe. Breathing is intended to release energy to be used by organisms. It is a reaction that oxidizes a compound rich in energy, obtaining poor products in it (carbon dioxide and water).

2: Plants contain a wide variety of pigments that give rise to the colors that we see in them. These pigments are chlorophyll-a (intense green), chlorophyll-b (green), carotenes (orange), xanthophylls (yellow), anthocyanins (reddish, purple, or bluish), and phycobilins (red).

3. Autotrophic organisms are those that have the ability to produce their own food from inorganic substances, which is why they can also be known as producers or vegetables. The main examples of autotrophic organisms are plants, algae, archaea, and various bacteria.

The lake's pH has become acidic; in 1989, it was 6.7; by 1996, it had dropped to 5.1. This shows that the increase in the acidity which has several bad impacts on the lake water ecosystem and its community.

The freshwater ecosystem differs from the oceanic saltwater ecosystem in that freshwater contains phytoplankton, edible fish, and so on. The fresh water has a normal pH, but the pH decreases and induces acidity when the water is polluted with different chemicals, such as nitrogen oxide, sulfur dioxide, etc.

When acid rain happens due to man-made pollution, this further adds acidity to the fresh water, and as a result, the species that live in the lake are not able to live and breathe properly due to a lack of oxygen. The acidity in the table increased year after year from 1989 to 1996.

Hence, the acidity of the lake increased and the pH decreased in these years, from 1989 to 1996.

Explanation:

A protein deficiency causes diverse symptoms because immune, nervous, and muscle system cells require proteins for structure and regulation.

Proteins are the building blocks of bones, muscles, cartilage, skin, and blood. They also help in transporting oxygen, helps in blood clotting during injuries, etc.

The cellular activities that sustain a single-cell organism through its lifetime include nutrient uptake, metabolism, growth, reproduction, and waste elimination. These processes ensure the organism's survival and allow it to carry out essential functions.

To elaborate, single-cell organisms obtain nutrients from their environment through various means, such as diffusion, active transport, or phagocytosis. Once inside the cell, these nutrients undergo metabolic processes like glycolysis, the Krebs cycle, and oxidative phosphorylation to generate ATP. This energy is utilised for growth, repair, and maintenance of cellular structures.

Additionally, single-cell organisms reproduce through processes like binary fission or budding, enabling them to proliferate and pass on their genetic material. Waste products generated during metabolism are eliminated through exocytosis or diffusion to maintain cellular homeostasis.

Answer: Sterilization.

Explanation:

Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.

Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).

Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.

Examples of sterilization include physical methods and chemical methods. Physical methods include:

Chemical methods include a variety of chemicals in liquid and vapor form, for example:

The end rocky part of two continents has similar composition, the presence of similar fossils of animals and climate

Explanation:

Alfred Wegener find out the end rocky part of two continents has similar composition, the presence of similar fossils of animals and climate so he presented the theory of continental drift that occurs 200 millions years ago. The main reason for the rejection of Wegener's hypothesis because he provides no mechanism for the movement of the continents. Wegener thought that the force of Earth's spin was sufficient for the drifting of continents from each other but other scientists says that it is too weak to drift the continents.
