Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of their own species. Which isolating mechanism does this describe?A.)behavioral
B.)temporal
C.)geographical
D.)anatomical

Answers

Answer 1

Answer:

A reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.

Reproductive isolation refers to the mechanisms that prevent a species from mating with others, which have fundamental importance from an evolutionary point of view.

These barriers to fertilization can be divided into:

prezygotic isolation barriers, which prevent the fertilization of the egg
postzygotic isolation barriers, which prevent the generation of fertile offspring.

The most important prezygotic isolation barriers include, among others, habitat isolation, behavioral isolation, mechanical isolation, etc.

Behavioral isolation mechanisms are characterized by mating rituals (for example, the songs of males in certain bird species), which are capable of generating reproductive barriers.

In conclusion, a reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.

Answer 2

Answer:

The isolating mechanism involved is the behavioral change (A).

Further Explanation:

Isolating mechanism are those characteristics of the species that prevents them to reproduce with other members of the species.

There are various types of isolating mechanism:

1. Behavioral- Reproductive isolation that arises due to the behavior of the individual during their mating period.

2. Temporal- The species breeds at different time or they may have different breeding season, therefore this can lead to reproductive isolation.

3. Geographical- The isolation of species because they occupies different habitats.

4. Anatomical- Isolation that arises due to different internal structure of the species.

Example of isolating mechanism - when two species of flies, Drosophila melanogaster and Drosophila simulans, can mate however they usually do not mate. But even though they are kept with each other in any lab, males court the females of both species but the females prefers to mate with males that belongs to the same species.This example shows the behavioral isolation.

Answers

The following types of changes that can happen in the rock cycle:

- igneous rock to sedimentary rock
- igneous to metamorphic
- sedimentary rock to to metamorphic
- metamorphic to sedimentary

Answer:

All are correct

Explanation:

An igneous rock can be converted into sedimentary rock when it is exposed to the surface because only then it will start decomposing by the action of water and wind

In the same way a metamorphic rocks on being exposed can be broken down into sediments

An igneous rocks can be converted into metamorphic rock when it is buried deep into the Earth crust at high temperatures and pressures

Sedimentary rocks become metamorphic only when they are subjected to heat and pressure from burial.

And lastly Metamorphic rocks of one form can be converted into metamorphic rock of other form.

Hence, all the given changes are correct

Which system most likely interact and cause the severity of infections to vary?

Answers

The answer is an immune and endocrine system.

Immune and endocrine system are connected in a complex way. Hormones are specific modulators of immune cell and are able to affect their activation and function. The severity of infection depends on their interaction. For example, testosterone can suppress the immune system. In the case of infection, the body is more susceptible to infection. This can partially explain the fact that autoimmune diseases are more common among the women than men.
