Which is an example of temporal isolation?

Biology
1 answer:
Tom [10]4 years ago
4 0

Answer:

A. flowers that bloom in different months

Explanation:

Temporal isolation is a prezygotic barrier that is caused by the inability of two closely related species to interbreed as a result of differences in breeding season.

If two related species of plants have flowers that bloom in different months, the possibility of both fertilizing each other is very slim. Both flowers won't be able to interbreed as a result of this reproductive isolation mechanism, called temporal isolation.

Blood type is controlled by two equally dominant genes. What type of example is this?
Angelina_Jolie [31]

The type of example is Codominance.

<u>Explanation:</u>

  • The term codominance represents the relation between two alleles at a point when animals heterozygous for the two alleles present both of the phenotypes recognized in animals homozygous for one allele or the other.
  • Codominance happens when two versions, or “alleles,” of the identical gene are present in a living thing, and both are revealed.
  • Instead of one trait being prevailing over the other, both traits develop.It also occurs in some less noticeable traits, such as blood type.
  • It is easy to spot codominance in plants and animals that have more exceeding than one pigment color.
  • Spattered cows and flowers with corollas of two different colors are examples of codominance.

Which best illustrates a result of natural selection?
Yanka [14]

Answer: The correct answer is -

D) giraffes having increasingly longer necks over time.

Natural selection is an evolutionary mechanism that was proposed by Darwin.

According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.

Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).

This is considered as a peculiar example of natural selection.

Which step is not part of a normal convection cycle?
mixer [17]

Answer:

D.  Warmed air sinks  is not a normal convection cycle outcome

Explanation:

Warm air is buoyant and rises.  Cold air is dense and sinks.

Think of fog in the air.  Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.

Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.
