Select ALL the correct answers.A forest was cleared to build a road. Which two would be the most likely effects on the ecosystem
Kryger [21]

Answer:

Some species will develop adaptations to survive in the deforested land.

Some populations will migrate out of the deforested area.

Explanation:

The deforested land will be able to support large trees eventually in the future, and animals cannot instantly adapt to anything.

Therefore, the most logical answers are populations will migrate to forest lands and species will eventually develop adaptations to help them in the newly deforested land.

I hope this helps! :)

Sort the different barriers into their modes of reproductive isolation. A snail with a flat disc-like shell will not be able to
Stella [2.4K]

Answer/Explanation:

Types of reproductive isolation include: temporal, ecological, mechanical, and behavioural.

A snail with a flat disc-like shell will not be able to mate with a snail having a conical shell - this is an example of mechanical isolation, where the animals are physically unable to mate due to incompatible body shapes and sizes.

The reproductive organs of male bush babies do not match with the reproductive organs of females of other bush baby species. - this is another example of mechanical isolation, as the sexual organs will physically not allow reproduction between these species

The mating call of a cricket is not recognized by a cricket of other species - this is an example of behavioural isolation, which results from incompatible mating rituals. I.e. the animals do not respond to each others mating behaviours

The signals sent by a male firefly are not recognized by the female firefly of other species. - this is also an example of behavioural isolation.

Temporal isolation is where species cannot interact because they do not have the same mating seasons or are not active at the same type of day. ?Ecological isolation occurs when two species do not come into physical contact to one another because they access different areas of the habitat. E.g. mating zones, food sources or nesting sites.

What problem would most likely to occur if a haploid cell attempted to perform meiosis? the cell could not replicate its dna pri
Cerrena [4.2K]

The answer is; the cell could not pair homologous chromosomes during meiosis.

For meiosis to occur, the sister chromosomes pairs line up in the metaphase-plate so that each chromosome of the pair is pulled to the opposite pole by the spindle in anaphase. Therefore, meiosis can only occur in cells with normal ploidy so the ploidy halved by meiosis.

Quiz: sensation and perception select the best answer to each question. our perception of the brightness of a color is affected
zmey [24]

Our perception of the brightness of a color is affected mainly by: the amplitude of light waves.

Night and peripheral vision depend mainly on rods, while daylight and acute vision depend mainly on cones.

The amount of light entering the eye is regulated by changes in the size of the pupil.

If you project a red, a green, and a blue light into space, the point at which the three lights cross will lead to the perception of white light.

eric has been wearing red welding goggles for the past 30 minutes. Based on the opponent-process theory of color vision, when Eric takes off the red goggles, he should expect that objects will temporarily appear to be green.
