Answer:
b. Trans fats are worse for heart health than saturated fats because they raise LDL cholesterol and lower HDL cholesterol.
c. Increasing intake of plant foods may be one of the easiest ways to decrease LDL cholesterol.
d. Typically, the higher your consumption of saturated fats, the higher the LDL cholesterol levels in your blood.
Explanation:
Generally, the consumption of saturated fat increases the amount of LDL cholesterol in the blood system while the consumption of unsaturated fat can reduce the amount of LDL cholesterol in the blood system. In addition, the consumption of plant food can reduce the amount of LDL in the blood system. Trans fats are more harmful to one's heart than saturated fat because they can increase the amount of cholesterol in the blood system.
Answer:b,c,d
Explanation:a. Unsaturated fats are mostly beneficial to health, e.g- omega 3 fatty acids, and are not known causes of LDL increase.
b. Trans fats are known to increase LDL cholesterol while also decreasing HDL cholesterol levels. We do not find this in saturated fats which are known to only increase LDL cholesterol.
c. Plants possess "soluble fiber" that drastically help to reduce cholesterol levels. They are known to be very low in saturated fats, and also free of cholesterol.
d. Saturated fats are common causes of elevated LDL in blood stream.
e. Dietary cholesterol as opposed to serum cholesterol are fats found in our diets(food) that may contain high levels of cholesterol that increase LDL levels in blood.
Answer:
893 snakes after first year
Explanation:
total population= 900
death = 30 per year left= 900-30= 870
birth each year= 20 per year so 870 +20= 890 snakes
6 snakes migrate into the population = 890 + 6= 896 snakes
3 migrate out of the population per year = 896-3= 893 snakes
After accounting for annual birth rate, death rate, and net migration, the snake population after one year would be 893 individuals.
To find out how many individuals are in the population after the first year, we start with the initial count of 900 snakes. We then subtract the death rate, or number of snakes dying per year (30), add the birth rate, or number of snakes being born per year (20), then also add the net migration, or difference between snakes moving into and out of the area (6 entering - 3 exiting = 3 net influx).
So the calculation would look like this: 900 (initial population) - 30 (death rate) + 20 (birth rate) + 3 (net migration) = 893
Therefore, after one year, there would be 893 snakes in this population.

Answer:
b. grasshopper effect
Explanation:
Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.
When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.
