A.) Angiosperms have flowers that attract organisms like insects, which aid in fertilization.
Answer:
Genetic diversity in a small population, with a high level of genetic drift and with very little migration will decrease because existing alleles will be lost and few new alleles will be introduced over time (option A).
Explanation:
Evolution - linked to the natural selection and perpetuation of a species - depends, in large part, on three fundamental factors to make it happen:
- Mutations
.
- Genetic drifts.
- Migrations.
In small and isolated populations, very little genetic variation, high levels of genetic drift and very few mutations can be observed, which could lead to some alleles being lost and the species may become extinct.
Genetic drift (GD) is an important factor in terms of natural selection, as it is the result of allelic variations that occur from one generation to another. In large populations, GD is low, given the cross between different individuals is greater. A characteristic of GD in small populations is that their levels are very high, and this leads to the eventual loss of alleles.
In this small population, without the possibility of migration -few new alelles will be introduced- genetic variation will decrease, due the genetic flow is low, reducing reproductive fitness and weakening the population's resistance to environmental changes, which could result in the long-term extinction of the species.

Answer:
The term “reptile” is derived (Made) from a Latin word meaning “creeping animals.” These animals include snakes, lizards, crocodiles, alligators, turtles, geckos, and chameleons, with lizards and snakes species making up the majority of all reptiles. Reptiles are cold-blooded animals which means they are unable to regulate their own body temperature. Reptiles are Oviparous (Egg laying). Reptiles also have chains of bony elements from the tail to the head. The bony endoskeleton consists of cranium or skull, appendages, and limb girdles. The endoskeleton protects the inner tissue and also aids in body movement. Skeletons differ from one species to another, with crocodiles having some of the largest body structures in this class.
