A biology problem, please come in and do me a favor

The answer is free water.

1.Combine with water.

Definition: This part of the water is combined with other substances in the cell, does not flow freely, and accounts for about the total amount of water in the cell.

Function: It is a structural component of the cell.

2. Free water.

Concept: Refers to water that exists in a free way and can flow freely.

Function: It is a good solvent in the cell, and many kinds of substances are dissolved in this part of the water; It is the liquid environment in which cells live; It is a medium for various chemical reactions within the cell; Directly involved in various chemical reactions within the cell; The free flow of free water also facilitates the transport of cellular matter.

Cell metabolism is fast, the content of free water increases, and the content of bound water decreases, so the proportion of bound water decreases compared with free water, cell metabolism slows, the content of free water decreases, and the proportion of bound water increases compared with free water.

Combine with water. Because of the vigorous metabolism, the content of natural organic matter is high, and the content of organic matter is high, and the content of bound water is naturally high.

The content of free water is relatively high.

Vigorous metabolism means that the anabolism and catabolism of substances are carried out at a high speed, and the frequency and speed of transportation of organic and inorganic substances are also relatively high, which require free water as a solvent and metabolite (metabolic raw materials, intermediate products, end products).

In addition, in biological cells, bound water cannot be moved at will, and mainly plays the role of a structure. Free water can flow.

You're a sophomore in high school, read more textbooks and pay attention to the definitions in the textbooks!! (If I hadn't said it).

Free water, which is intracellular, water involved in metabolism, comes from free water and has nothing to do with bound water. Only when the seeds germinate, the water consumed by the cells for aerobic respiration comes from the bound water.

Viruses usually have the benefits of preventing and treating certain diseases and promoting cell fusion, but they also have disadvantages such as harming the body's health and selling blind health. This is said to the whole body to match the shirt.

But you're talking about viruses multiplying inside cells. If he argues for him, he will definitely hurt this host. It's like parasites in our stomachs that eat away at our bodies and absorb our nutrients.

The genotype is ww, and the pollen produced is half of w and half w, so half of it turns blue.

Crossed with white corn, it can be judged by the color of the corn kernels on the fruit.

In the genotype, genotype 1 2*1 4yyrr 1 2*1 4yyrr 1 2*2 4yyrr 1 2*2 4yyrr 1 2*1 4yyrr 1 2*1 4yyrr remove the parental yyrr and yyrr genotypes, and the remaining 4 8 is 1 2

The yellow round grain genotype should have Y and R, that is, the yyrr and yyrr green wrinkle genotypes are yyrr, and the homozygous in F2 generated by Yyrr and Yyrr cross is 0; Yyrr and Yyrr are homozygous in F2 and Yyrr account for 1 2*1 2=1 4, and Yyrr accounts for 2 3 in yellow round grains, so homozygous in the offspring account for 1 4*2 3=1 6

b c Question 3 will not be understood.

125kg

At most, only 20% of the energy of each level can be absorbed by the next level, which is the least asked here, so it should be calculated as 20%.

1kg whale, 5kg seals, 25kg small fish, 125kg phytoplankton.

The self-aware whale (top consumer) is calculated as at least a consuming producer with a transfer efficiency of 20%: 1 (20%) (20%) (20%) = 125
