What causes there to be a H+ ion concentration gradient to build up inside the thylakoid space? Check all that apply. a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space. b. A special enzyme produces more H+ ions. c. Photons of light create more H+ ions. d. The photolysis of water releases H+ ions into the thylakoid space.

Answers

Answer 1

Answer:

a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

d. The photolysis of water releases H+ ions into the thylakoid space.

Explanation:

This question describes the first stage of photosynthesis, which is LIGHT-DEPENDENT REACTION. The light dependent reactions involve creating ATP (energy carrier) and NADPH (electron carrier) needed for the Calvin cycle (light independent stage) to occur.

The ATP is formed by pumping hydrogen ions (H+) into the thylakoid space/lumen, hence, creating a electrochemical gradient needed for ATP synthase to synthesize ATP. The buildup of H+ ions is caused by:

- The electrons that arise when light photons hit a chlorophyll molecule is used to provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

- The photolysis of water results in the production of electrons (e-) and hydrogen ions (H+). These hydrogen ions are released into the thylakoid space.

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.

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

Answers

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.

root hair cells have a high ion concentration . explain how this is maintained and its importance​

Answers

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.

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.​

Answers

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.
