Answer:
If a person has a diet high in saturated fats, LDL cholesterol molecules can carry cholesterol from the liver to cells and to the arterial walls whereas HDL cholesterol transports cholesterol from the cells to the liver where it is converted to bile salts which can modulate cardiovascular function.
Explanation:
Cholesterol is a lipid generated in the liver that is used to make hormones and vitamin D, but can also be ingested when eating fats.
Cholesterol can be divided into two types: LDL (low-density lipoprotein) and HDL (high-density lipoprotein).
LDL is commonly known as the "bad cholesterol" and is responsible for the deposit of cholesterol in the walls of arteries, which generates atherosclerosis and can potentially lead to strokes or heart attacks because it occludes the vessels and makes it impossible for the blood to advance.
HDL is also called "good cholesterol" because it takes the cholesterol from the cells to the liver where it'll serve a good cause, instead of blocking the arteries.
To reduce the amount of LDL, it's best to limit the consumption of fatty meats, dairy products and other saturated fats. Foods with a good amount of HDL are those with unsaturated fats, like fish, nuts and seeds.
Answer:
1. Water vapor condenses to form clouds.
2. Water falls as rain, snow, and sleet.
3. Water flows down mountains and hills.
4. Water joins streams or forms groundwater.
There are multiple factors that influence the amount of water that flows in a river.
1. A factor upstream like rain can cause the water level downstream to rise for a short period in time.
2. A blockage in a runoff stream can cause the main rivers water level to rise due to the lack of available runoff path for the water to take.
3. Also the melting of snow can cause the water level to rise as well.
Answer:
The correct option is D.
Explanation:
Adaptive radiation refers to the ability of living organisms to evolve rapidly from an ancestral forms into variety of other forms especially when the organisms move into a new environment that has abundant resources. The resources, which are present abundantly in the environment allow the living organisms to spread out in the environment and to find different habitats in the environments that favour their survival.
In the question given above, adaptive radiation allows plants to fill different habitats (niches) that are found on land and to spread out rapidly.
Because they stain them a florescent colour so that they can shine light on them and they'll glow
