Answer: The carbon to produce carbohydrates in second stage of photosynthesis comes from CARBONDIOXIDE.
Explanation:
Photosynthesis is the process by which green plants use light energy from sunlight with carbon dioxide and water to produce glucose.
This involve two stages; the light dependent and light independent stage(dark stage).
The light independent is the second stage and it uses carbon atoms from carbondioxide , which gas exhaled by animals to produce carbohydrates. It is also referred to as Calvin cycle because it used energy stored by the light dependent stage to form carbohydrates.
Answer:
1) Segmental (tertiary) bronchi.
2) Type II alveolar cells.
3) Respiratory bronchioles.
4) Type I alveolar cells.
5) Alveolar duct.
6) Type II alveolar cells.
7) Type I alveolar cells.
Explanation:
All of the structures and cells mentioned above are part of the respiratory system.
The respiratory system is composed of several organs and its main function is to take in oxygen and expel carbon dioxide.
The gas exchange occurs in the alveoli, tiny air sacs in the lungs. But to reach the alveoli, the air first goes through the nose, the mouth, the larynx, the trachea, the bronchi and the bronchioles.
Answer;
A. gases or particles present in high enough concentrations in the atmosphere to harm humans, other organisms and structures.
Explanation;
Air pollution is a type of pollution that occurs when harmful or excessive substances such as particulates, gases and biological molecules are introduced into Earth's atmosphere.
The burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles is the major cause of air pollution.
Answer:
ribosome- decoding the message and the formation of peptide bonds
mitochondria- generate most of the chemical energy needed to power the cell's biochemical reactions.
vacuole- maintain water balance
chloroplast- convert light energy into relatively stable chemical energy
Explanation:
I believe this problem has the following choices:
a. It was hard to get the fish to breed and produce
offspring for the aquaculturist to raise.
b. Because the fish were stressed in tanks, they required
much more food, reducing the profitability of rearing the fish this way.
c. The fish had to be raised in a community with several
species of fish in the same tank, and they would attack and eat each other.
d. Marine fish are more aggressive than their freshwater
relatives and they tended to fight a lot, often killing some of the other fish
in the tank.
The correct answer is:
c. The fish had to be raised in a community with several
species of fish in the same tank, and they would attack and eat each other.
