Kneel down and ask for a few first year biology questions

I'll come, it's a piece of cake.

The vascular output per minute of the heart chamber is the same, and the output per minute is the cardiac output; Item B is clearly wrong; C, the blood pressure is absolutely different, the cardiac artery is greater than the venous blood pressure because the transportation route is longer, and the aorta is greater than the pulmonary vein blood pressure because the aorta is transported to the whole body, while the pulmonary artery is only transported to the lungs to the heart; Circulatory pressure should be left until blood pressure is too high for a long time].

Serum does not have fibrinogen, plasma has fibrinogen].

Remember, a slower heart rate [in people who exercise a lot, indicates that the heart is capable and therefore has a good ability to contract].

2 lobes in the left lung, 3 lobes in the right lung].

The exchange of gases between the internal environment and the outside world is that the lungs are ventilated and produced in the alveoli of the lungs].

a a (glucose and other nutrients, which are generally not present in serum) ab

d (2 lobes of the left lung, because there is a heart on the left, 3 lobes of the right lung) a

I think the sixth question is B

You can flip through the books.

(This question can be solved using the method of eliminationThere is no seed, what is the wheat? c.Chlamydomonas is an algae organism that does not have the structure of rhizomes and leaves; d.The seeds are coated with a peel - Chlamydomonas has no seeds, let alone a peel coating).

2.Heating in high school is called boiling water bath, if it is not heated in water, boiling water will cause some substances in plant cells to hydrolyze and disappear.

3.The main site of plant respiration is the mitochondria.

4.Penicillin – a class of antibiotics that can damage the cell wall of bacteria and play a bactericidal role during the reproductive period of bacterial cells.

It depends on the structure of the pathogens of hand, foot and mouth and influenza A;

5.The difference is the quality of dissolved calcium hydroxide in the water, the former is more, the latter is less;

6.Conditioning

7.What are these things???

The answer is b. Chlamydomonas and moss have no seeds, abarony.

Chlamydomonas and mosses do not have the differentiation of rhizomes and leaves, c wrong.

Of the four, only the seeds of wheat have a peel on the outside, d'wrong.

Of these four plants, Chlamydomonas belongs to the unicellular algae. Wheat belongs to the monocots among angiosperms.

Mosses are bryophytes. Metasequoia is gymnosperms.

2 This is because the boiling point of alcohol is lower than that of water, and if it is heated directly on the fire, not only will the alcohol evaporate too quickly, resulting in waste, but also the effect of dissolving chlorophyll is not good enough, which is especially easy to ignite the danger of alcohol.

3. The main site of plant respiration is mitochondria.

4 No, I don't know (this is only learned in the third year of junior high school).

5. The saturated limestone solution is the water-soluble night that reaches the solubility of the temperature, and the clear liquid is the liquid that keeps the liquid free of turbidity and can be used to test CO2

6.Knee-jerk reaction.

7.These things.

1b2 Avoid hazards.

3 stomata. 6. Environmental impact organisms.

1 b3 is mitochondria.

6 Conditioning.
