Plants using the CAM pathway occur in many locations but are most common in very arid locations, such as deserts. What deserts occur in North America and where are these deserts located?
The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.
CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.
With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.
An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.
In North America, the desert that occurs there is the Great Basin Desert. It spreads into different states which include:
NevadaWestern Utah, Eastern California, andIdaho.But the major part of Nevada is occupied by the Great Basin Desert.

how does carbon move through the system when there is light
Answer:
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.
Explanation:
The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.

Which of these changes is a possible negative consequence of farmers
allowing livestock to overgraze a pasture?
O A. Desertification
O B. Shortage of freshwater
O c. Deforestation
O D. Abundance of clean air
Given what we know, one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification.
What is Desertification?In simple terms, desertification is when the land becomes so dry and void of life that it can be considered a desert. This can be caused by many factors, primarily the lack of vegetation.How can overgrazing lead to Desertification?Overgrazing can lead to desertification due to the fact that the plants and vegetation are not given the opportunity to regrow.The presence of vegetation allows the soil to remain moist and fertile by moving minerals and water through it. Overgrazing causes a lack of vegetation which creates dry and infertile land, which leads to complete desertification.Therefore, we can confirm that one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification due to the damage caused to the soil in the absence of vegetation.

Which statement describes an important role of carbon dioxide in Earth's atmosphere?
Animals breathe carbon dioxide.
O Plants use carbon dioxide to make food.
O Carbon dioxido helps animals make proteins.
Carbon dioxide forms clouds that produce rain
Answer:Plants use carbon dioxide to make food
Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.
Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.
CO₂ + H₂O → O₂ + glucose (food)
This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.
The purpose of degrading cyclins is to stop the cell cycle from happening.

Which mechanism allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries
Answer:
Diffusion.
Explanation:
The mechanism that allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries is simple diffusion.
Simple diffusion is a passive transport mechanism that allows lipid-soluble substances to move across the membranes of endothelial cells in capillaries. This process occurs down a concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy expenditure.
The membranes of endothelial cells, which make up the walls of capillaries, are composed of a lipid bilayer. Lipid-soluble substances, such as oxygen, carbon dioxide, steroid hormones, and certain lipid-soluble drugs, can readily diffuse through this lipid bilayer due to their ability to dissolve in and pass through the hydrophobic interior of the membrane.
Unlike lipid-soluble substances, water-soluble substances, such as ions and polar molecules, are unable to passively diffuse through the lipid bilayer. Instead, they rely on specific transport mechanisms such as facilitated diffusion or active transport to cross the endothelial cell membrane.
In the context of capillaries, simple diffusion allows lipid-soluble substances to move from the bloodstream through the endothelial cell membranes and into surrounding tissues or vice versa. This process plays a crucial role in the exchange of gases, nutrients, and waste products between the bloodstream and the tissues.
It is important to note that while simple diffusion allows for the passage of lipid-soluble substances, the movement of these substances can also be influenced by factors such as concentration gradients, molecular size, solubility, and the presence of transport proteins. However, the primary mechanism by which lipid-soluble substances traverse the endothelial cell membranes of capillaries is through simple diffusion.
