Someone Please Help!! ASAP!!!!!!What Trend Do You Notice About The Relative Amount Of Carbon Dioxide

Answers

Answer 1

Answer:

The proportion of oxygen went up because of photosynthesis by plants. The proportion of carbon dioxide went down because: it was locked up in sedimentary rocks (such as limestone) and in fossil fuels. it was absorbed by plants for photosynthesis.

Explanation:

Answer 2

Due to plant photosynthesis, the amount of oxygen increased. Because carbon dioxide was trapped in sedimentary rocks (like limestone) and fossil fuels, its percentage decreased. Plants utilized it for photosynthesis.

What is photosynthesis?

Carbon dioxide concentrations CO2 are expected to rise, which will raise serious concerns about how plants react to the gas. Increased photosynthesis results from elevated CO2 in plants, which increases biomass and carbohydrate production.

It varies both within and across species as to which organ receives the extra carbs. There is currently a paucity of knowledge regarding how the greater concentration of carbohydrates generated under rising CO2 affects the sugar sensing and signaling pathways of plants.

Therefore, Due to plant photosynthesis, the amount of oxygen increased. Because carbon dioxide was trapped in sedimentary rocks (like limestone) and fossil fuels, its percentage decreased. Plants utilized it for photosynthesis.

A tissue through which gases are exchanged between the blood and the air in the lungs.
a) stratified squamous epithelium
b) simple squamous epithelium
c) simple culumnar epithelium
d) simple cuboidal epithelium

Answers

Answer:

B- simple squamous epithelium.

Explanation:

Alveoli consists of simple squamous epithelium which is the main site for gas exchange. Thus, the correct option is B.

Gas exchange through the process of pulmonary respiration takes place in the alveoli (singular alveolus) of the lungs.

Alveolus is made up of two types of cells - type I and type II alveolar cells.

Type I alveolar cells are simple squamous epithelial cells supported by a thin elastic basement membrane. These cells form a continuous lining of the alveolar membrane and are the main sites for gas exchange.

Type II alveolar cells are septal cells that are present in between the type I cells. They secrete a fluid to keep the surface between the cells moist and it also contain surfactants for reducing the surface tension and preventing the collapse of alveolus.

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?
Α.
Substances are moving rapidly across the cell membrane.
B. ATP is being rapidly consumed near the cellular membrane,
C. Substances are moving from high to low concentrations.
D. Substances are moving through channels in the cell membrane

Answers

Answer:D. Substances are moving through channels in the cell membrane

Explanation:

In case of active transport, ATP is being rapidly consumed near the cellular membrane. Thus, the correct option is B.

What is Active transport?

Active transport is the movement of molecules or ions across a cellular membrane from a region of its lower concentration to a region of its higher concentration against the concentration gradient of the molecules or ions. Active transport requires cellular energy to achieve this movement of molecules or ions. The cellular energy is supplied in the form of ATP (Adenosine triphosphate) molecules.

The transport of molecules occurs through transport proteins such as carrier proteins and channel proteins against the concentration gradient.

Therefore, the correct option is B.
