I believe the correct response is the third option. Have higher resolution that allows you to view smaller specimens.
No their babies won't look alike.
<h3>Explanation:</h3>
Both the couples mentioned here i.e. Sally - Harry and Emily - Ken are both identical twins. So they have similar pairs of genetic setup. This was possible because they developed from same zygote.
But during gametogenesis, crossing over and independent assortment occurs which brings about variation in genetic setup among the offspring. And it's very less probable that same crossing over will occur between the gametes of these couples. So, their offsprings won't look same.
Answer:
Tropical Climate
Explanation:
If glossopteris fossils were found in Antarctica, the climate of this continent before was a Tropical Climate.
I disagree with this statement. Asexual organisms are at a lower risk for extinction due to the fact that they do not need a partner to procreate. They have an easier time making offspring.
Answer:
Explanation:
Species: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
Population: a particular group or type of people or animals living in a place.
Gene pool: the stock of different genes in an interbreeding population.
Mutations: the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
Lateral Gene Transfer: the movement of genetic material between unicellular and/or multicellular organisms other than by the transmission of DNA from parent to offspring (reproduction).
Single-gene Traits: when a trait is linked to one gene-pair that consists of two alleles.
Polygenic Traits: is one whose phenotype is influenced by more than one gene.
