The organic chemicals that help cell membranes to conserve internal fluids are _____. a. hormones
b. phospholipids
c. amino acids
d. proteins

Answers

Answer 1
Answer: the most appropriate answer is B ! as it helps in maintaining isolated internal environment !!
Answer 2
Answer: The organic chemicals that help cell membranes to conserve internal fluids are the phospholipids. They are composed of fatty acid, glycerol, phosphate group and a polar molecule. The phosphate group and polar head region of the phospholipids is attracted to water while the fatty acid is repelled by water. They are a major component of the cell membrane in which it encloses the organelles of the cell. It also limits what enters and exits the cell because of its two heads.

list three ways carbon is stored in the biosphere


Answers

Carbon is present in every single living thing. The carbon cycle is the constant flow of carbon atoms through Earth's crust, oceans, atmosphere, and living beings.

What are the carbon reservoirs?

Rocks and sediments contain the majority of the carbon on Earth. The ocean, the atmosphere, and living things contain the remaining components.

The primary cause of the rise in carbon dioxide concentrations is the use of fossil fuels by humans as a source of energy.

The majority of carbon is swiftly released into the atmosphere as carbon dioxide gas when fossil fuels are burned by people to run factories, power plants, vehicles, and trucks.

Therefore, carbon present in atmosphere as a carbon dioxide and in oceans as dissolved carbon dioxide and in rock as fossil fuel.

What would happen if the amount of fresh water entering mono lake decreased?

Answers

If the amount of fresh water entering mono lake decreased, the concentration of salinity increases and in the last the lake dry out.

What happen when freshwater is not entering into the lake?

The water in the lake is snowmelt and rainwater runoff from the mountains. It enters the lake through streams. Water can only remove by evaporation. When the water evaporates, the salts left behind.

So we can conclude that if the amount of fresh water entering mono lake decreased, the concentration of salinity increases and in the last the lake dry out.

There's two things that will happen as a result of decreased fresh water income in the Mono Lake:

1. Salinity will increase; as the amount of freshwater will decrease, the Mono Lake will experience increase in salinity of its waters, which will be caused by the lower amount of incoming water and the big evaporation because of the high temperatures.

2. Dry out; the lake will eventually dry out, and that will be due to the bigger evaporation of its waters in comparison to the freshwater that's entering into it.

During normal cell division, a parent cell having four chromosomes in G1 will produce two daughter cells, each containing ______.

Answers

When a parent cell splits into two daughter cells, it is mitotic cell division (Mitosis). So if the parent has four chromosomes and the daughter cells are identical, they will also each have four chromosomes. For example, we humans have 46 chromosomes, 26 of them from the mom and the dad.

Which characteristic of prokaryotic organisms makes them different from eukaryotes

Answers

Answer:

Prokaryotes are the most primitive form of life that exist on earth. They came before eukaryotes.

The main difference is the presence of nucleus which is present in eukaryotes and absent in prokaryotes.

The genetic material of prokaryotes are dissolved in the cytoplasm whereas in case of eukaryotes the genetic material is in-tacked inside a double membrane organelle nucleus.

There are many more membrane bound cell organelles found in eukaryotes that are absent in prokaryotes.

the prokaryotic cells do not have a nucleus or membrane bound organelles
