root hair cells have a high ion concentration . explain how this is maintained and its importance
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Explanation:
To maintain the concentration gradient and so the constant movement of water into the root hair cell by osmosis, the root hair cell actively transports mineral salts into the cell.
Root hairs are important because they absorb the majority of the water and nutrients required by the plant. The root hair cell actively transfers mineral salts into the cell to maintain the high ion concentration.
Root hairs, also known as absorbent hairs, are outgrowths of epidermal cells, which are specialized cells found at the root's tip.Root hairs are important because they absorb the majority of the water and nutrients required by the plant. In legume plants, they are also directly involved in the production of root nodules.The root hair cell actively transfers mineral salts into the cell to maintain the concentration gradient and hence the continual passage of water into the cell by osmosis.

Freshwater can be renewed, but environmentalists consider it nonrenewable. Why is there a contradiction in classification?
Freshwater is recycled through the use of irrigation, bathing, and everyday use.
Freshwater is easily polluted or depleted before it can be replaced.
Freshwater evaporates and condenses, and then precipitation returns it to the lakes.
Freshwater is highly affected by global warming, and is quickly evaporating.

Mendel chose to study pea plants for their diversity. Give an example of an organism that would be difficult to use in the study of genetics. Justify your response in two or more complete sentences.
Answer:
Female Lions
Explanation:
I believe this would be a difficult organism to use in the study of genetics, because for years all Lionesses have looked extremely similar to us humans. While Male lions have a lot of differences from each other. Although, what could be studied is how they pass on their traits to their offspring.

Using all the words below, write a short paragraph explain convection currents
Convection Currents
Mantle
Crust
Heat
Less dense
movement
More dense
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean.Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.What contains the greatest concentration of lactic acid?

Evaluate each of the statements below. Select those that accurately describe the role of genes and chromosomes in the process of inheriting a specific trait. Choose ALL that apply. A) Chromosomes are made of DNA. B) There are 26 pairs of chromosomes in humans. 09 Alleles are the different forms of a gene that can exist. D) Chromosomes contain genes that control the inheritance of traits. E) Genes are made of chromosomes and contain all of the genetic information for an organism.
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
What do B and b represent?
