Answer:
c. increase HDL levels
Explanation:
Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.
Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.
Answer:
-involve cell division
-meiosismakes haploid cells(23 chromosomes) while mitosis makes diploid cells (46 chromosomes)
The gasoline engine where the air and fuel mixture is burned is called the combustion chamber. A piston is used to increase and decrease the volume which prepares the fuel to be mixed with air. A spark plug is ignited then to create the combustion thereafter.
The answer is because a part of the organism could die and the organism could continue to live.
In the very changing environment, such was when multicellular organisms evolved, the organisms that could adapt to that environment, survived. If in some moment multicellular organism emerged and its multicellularity helped him to survive, that is the reason this characteristic remained. On of the explanation is that multicellularity allows the organism to continue to live even if <span>a part of the organism dies.</span>
Answer:
- Populations must be very large -True
- The frequency of all genotypes must be equal. False
- Gene flow from other populations must be zero. True
- Matings must be random. True
- There should be no natural selection. True
Explanation:
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- <u>Random matings</u>: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes.
- No superposed generations: each individual can leave their gametes in the pool only once.
- No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles.
- <u>No migration</u>: There is no incorporation of gametes originated in another population.
- <u>Infinite population size</u>: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q.
- <u>No natural selection</u>: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
