No nucleus, they are prokaryotes
Answer: Option C. consists of ancestor species and all of its descendants groups.
Explanation:
Monophyletic clade refers to a group composed of a collection of organisms, including the most recent common ancestor of all those organisms and all the descendants of that most recent common ancestor.
A monophyletic clade is also called a taxon. By classifying organisms based on their biological diversity and evolutionary history, we can easily know, how different organisms, both past and present, are related to one another. Examples of monophyletic groups include: Mammals, birds, angiosperms, and insects.
Answer:
Explanation:
Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies
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:
Answer:
C. different alleles of the same gene
