Why does increasing soil salinity have adverse effects on plant cells?

1 answer:

8 0

Increasing soil salinity will have an adverse effect on plant cells. The movement of water from the soil to the plant is known as osmosis. There needs to be some salt in the soil for osmosis to take place. If the salt content in the soil is too high compared to the salt levels in the plant cells, the plant cannot absorb water and dies of thirst even though there is lots of water. The same occurs in the reverse.

Functionality of Genes and chromosomes is described below.

Explanation:

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.
Genes are contained in chromosomes, which are in the cell nucleus.
A chromosome contains hundreds to thousands of genes.Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
A trait is any gene-determined characteristic and is often determined by more than one gene.Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
The phenotype is the actual structure and function of a person’s body. The phenotype is how the genotype manifests in a person—not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
A karyotype is a picture of the full set of chromosomes in a person’s cells.

In the reaction ______ H2 + N2 ----> 2 NH3, what coefficient should be placed in front of H2 to balance the reaction?

schepotkina [342]

2NH3 is equivalent to N2 + H6 since the 2 at the beginning gets distributed to both atoms. Knowing this you can rewite the equation as

H2 + N2 = H6 + N2

The N2 can cancel out leaving

H2 = H6

You now have to ask ‘2 times what equals 6?’ The answer is obviously 3 at this point.

Answer: C. 3

How does water transfer when it evaporates from the ocean?

3241004551 [841]

Answer:Most of the water that evaporates from the oceans falls back into the oceans as precipitation. Only about 10 percent of the water evaporated from the oceans is transported over land and falls as precipitation. Once evaporated, a water molecule spends about 10 days in the air.
