What is osmoregulation?

Answers

Answer:

Answer 2
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis.[1] The higher the osmotic pressure of a solution, the more water tends to move into it. Pressure must be exerted on the hypertonic side of a selectively permeable membrane to prevent diffusion of water by osmosis from the side containing pure water.

Organisms in aquatic and terrestrial environments must maintain the right concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic if allowed to accumulate in the blood) through organs such as the skin and the kidneys.

Answer:

Zoology

Explanation:

It is the study of animals, a complex discipline that draws upon a diverse body of scientific observation and theory. It can be broken down into numerous sub-disciplines: ornithology (the study of birds), primatology (the study of primates), ichthyology (the study of fish), and entomology (the study of insects), to name a few. As a whole, zoology encompasses a fascinating and important body of knowledge that enables us to better understand animals, wildlife, our environment, and ourselves

Answer:

Which plant propagation process insures some genetic diversity?

Answers

Answer:

Seed propagation takes place during sexual reproduction. The production of seeds through auto-pollination or crossed pollination ensures some genetic variation.

Explanation:        

Seeds ensure the existence of genetic variation between plants. There are two general crossing systems in plants, which depend on pollination type.  

Self-pollination occurs when the flower pollen is transferred to the same flower stigma, reaching that individual egg to fertilize it. These are autogamous systems. Crossed pollination occurs when the mature pollen is driven by different pollinator agents from one flower to another, reaching the other flower stigma and fertilizing its eggs. These are xenogamous systems.

Sexual reproduction gives more possibilities to different alleles of a gene that did not appear in one generation to express in the next generation. Both types of pollination allow genetic variation, however by the occurrence of crossed pollination there are more chances to ensure the variability of the species and survival to environmental changes. While by self-pollination there are more chances to express the same genotype of the parental plant. The Xenogamous system has the advantage of avoiding the effects of endogamy in a population.

Which statements accurately describe fermentation? Select two options.

Oxygen is present during this process.
Cells may convert pyruvic acid to lactic acid.
NAD+ is converted to NADH.
Fermentation is an anaerobic process.
Additional ATP is produced after glycolysis.

Answers

Answer:

The answers are the second and fourth ones.

Explanation:

I did the assignment.

The statements that accurately describe fermentation are cells may convert pyruvic acid to lactic acid, and fermentation is an anaerobic process. The correct options are B and D.

What is fermentation?

Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the bubbling that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.

It is different from aerobic respiration because it occurs in the absence of oxygen and aerobic respiration occurs in the presence of oxygen. The product of fermentation is lactic acid, which is produced from pyruvic acid.

Thus, the correct options are: B, Cells may convert pyruvic acid to lactic acid, and D, Fermentation is an anaerobic process.

Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP

A. Transport from complex I produces more ATP.

B. Transport from complex II produces more ATP.

C. Both produce the same amount of ATP.

Answers

Answer:

A

Explanation:

ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.

Electron transport from complex I produces more ATP.

ELECTRON TRANSPORT CHAIN:

The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration.

The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis.

The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers.

Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space.

Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.

Growers around the world produce about 3.2 x 107 metric tons of sunflowers each year. One
metric ton is the same as 1.1 short tons. How many short tons of sunflowers do worldwide
growers produce annually?

Answers

Answer:

3.5264 x [tex]10^{7}[/tex]

Explanation:

The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.

In the given question, it has been mentioned that the growers around the world produce about 3.2 x [tex]10^{7}[/tex] a metric ton of sunflower.

So the short ton produced will be

= ( 3.2 x [tex]10^{7}[/tex] ) x 1.102

= 3.5264 x [tex]10^{7}[/tex] short ton.

Thus, 3.5264 x [tex]10^{7}[/tex] is the correct answer.

What are eukaryotic cells?

Eukaryotic cells are those cells that contain true cell organelle. These cells are present in the higher organism, and they perform complex functions like replication, mitosis, etc.

There are two types of cells. They are prokaryotic and eukaryotic cells. Prokaryotic cells are those that do not contain an organelle and a nucleus. They are present in smaller organisms.

The nucleus is the brain of cells. It controls all functions of cells, and it contains the genetic material of the organisms. In prokaryotic cells, the nucleus is absent and in eukaryotic cells, the nucleus is present. That is the difference between them.

Thus, the correct option is C. nucleus.

Herbivores best describes consumers that feed on other organisms such as plants and animals for energy.

What do you mean by herbivores?

A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.

Many herbivores have large, dull, flat teeth. These teeth are excellent for chewing and breaking down tough plant material. Carnivores have sharp, narrow teeth that are better for biting and tearing flesh. However, some herbivores also have strong, sharp teeth.

Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses.
