Answer:

I believe it would be B.) Quick drop in dissolved oxygen

Quick drop in dissolved oxygen is a possible consequence of solid pollutants in a lake or river.

Biochemical oxygen demand (BOD) is the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions.

Solid pollutants in freshwater bodies like river and lake generally corresponds to organic wastes such as leaves, flowers and clothes which lead to increase in number of microorganisms in these water  that further results in increase of BOD.

Drastic increase in microorganisms lead to drop in amount of dissolved oxygen in water, thus the possible consequence of solid pollutants in a lake or river is quick drop in dissolved oxygen.

Stomata

Explanation:

These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed.

Answer:

I think it is Chemical reactions produce glucose, ADP and NADPH

Explanation:

Photosynthesis is a chemical reaction that takes place to convert light energy. The photosynthetic light-dependent reaction forms glucose, ATP, and NADP⁺. Thus, option A is correct.

A light-dependent reaction is a photosynthetic reaction that occurs in the presence of sunlight and produces chemical energy in the form of NADPH and ATP.

The products of the photosynthetic light-dependent reaction are used in light-independent reactions. In light-dependent, the photosystem gets excited and produces ATP from ETC, leading to reduction of NADP⁺ and photolysis of the water molecule.

Therefore, ADP and NADP+ are produced at the intermediary stage of the light-dependent reaction which makes them different from the light-independent reaction.

B) They must consume their food.

Explanation:

Answer:

Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.

The cell wall serves as a protective and structural layer surrounding plant, fungal, and bacterial cells. It provides rigidity, support, and defense against external pressures and pathogens.

In various species, the cell wall serves as a robust outer layer. Its primary component in plants is cellulose, which helps to preserve cell structure, limit excessive water absorption, and promote growth. Chitin is found in the cell wall of fungi, providing both structural integrity and protection.

Bacteria have a variety of cell wall compositions; peptidoglycan, for example, is an essential part of many bacterial cell walls. Along with other cellular components, this "factory-like" part of the cell performs its functions. It is comparable to a factory's base, supporting the cell's framework, and worker, guarding against threats and preserving the cell's overall operation.

Answer:

21 chromosomes

Explanation:

Somatic cells are a diploid which have 2 sets of chromosomes. If two sets are 42 chromosomes, one set must be 21 chromosomes. Gametes are a haploid which have only 1 set of chromosomes. So in each gamete, there should be 21 chromosomes.

Answer: Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

Answer:

The carrying capacity would shoot downward.

Explanation:

The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).

Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).

Fermentation

Explanation:

Hope this helps!

The production of alcohol by yeast cells is the result of anaerobic respiration. The correct option is D).

All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.

When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.

During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.

Therefore, the correct option is D) Anaerobic respiration.

Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.

Explanation:

Hope this helps.

The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.

Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.

This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.

Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.

Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.

Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

Answer:

itosis is a process where a single cell divides into two identical daughter cells.

Explanation:

Mitosis is the only type of cellular division in which number of chromosomes is maintained

During the phase of the cell cycle known as mitosis, duplicated chromosomes are physically split in half to form two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.

Mitosis serves a very vital purpose in living creatures, and one of its functions is the regeneration and replacement of worn-out and damaged tissues. Mitosis contributes to the generation of identical copies of cells and, as a result, assists in the process of healing damaged tissue or replacing cells that have been worn out.
