Answer:
1. genetics
2. constant
3. genetic drift
4. Modern synthesis combines the ideas surrounding evolution and natural selection with those of genetics.
5. A genotype is the genetic makeup of an organism. It describes the DNA that underlies a trait. There are dominant and recessive alleles and heterozygous and homozygous genotypes. A phenotype is the physical manifestation of that genotype.
6. The most common type of mutation is a deleterious mutation. Natural selection acts to remove this allele from the population.
7. The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.
8. During sexual reproduction, each organism is provided a copy of chromosomes from each parent, and this allows for new combinations of DNA.
9. This isn't an example of genetic drift because there's a genetic component to the ability to withstand severe temperatures. Therefore, this is an example of natural selection, related to surviving extreme environmental conditions
Explanation:
Hi! :)
Okay so here are 3 listed ways:
So first we have Nitrosamines, then we have Cyanosis, and lastly Iodine Deficiency.
Now giving these answers, are you able to complete the question?

Answer:
A
. the fertilized egg and the cells produced by the first few cell divisions
Explanation:
Totipotent cells are those cells in developmental stage of multicellular organisms which can give rise to any part of the organism. It can give rise to both the placenta and the embryo.
After the fertilization, the cells produced in first few divisions are totipotent. This stage is also called as morulla stage. Once blastocyst stage is reached, totipotency is lost. All the cells of blastocyst are not totipotent. The inner cell mass of blastocyst is pluripotent which means it can give rise to the entire embryo except placenta. The trophoblast layer of blastocyst can only produce placenta.
Answer:
Synthesis Of Osmoprotectants
Explanation:
One Mechanism Halophiles use to survive in high concentrations of salt is the Synthesis Of Osmoprotectants, which are also known as compatible solutes. These work by balancing the internal osmotic pressure with the external osmotic pressure, making the two solutions isotonic, or close to it.
