Answer:
The correct answer is - 50% or 1/2.
Explanation:
In codominance both alleles express their traits and blend to make new traits, there is no dominance or recessive pattern found. In this question, there is FF have pink feathers, PP has purple feathers and mottled diriclaws (FP). Then a cross between pink feathers and mottled diriclaws would produce offspring:
F F
F FF FF
P FP FP
Here two out of four have pink feathers. That is 50%
Answer:
Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. Environmental change and isolation of groups of organisms play an important role in evolution. Environmental change is any change in an environment to which an organism must adapt. Change can be gradual, such as when mountains or deserts form, other species die out, or new species evolve.

Biotic Factors: Low Shrubs (sedges, reindeer mosses, liverworts, and grasses), Crustose and Foliose Lichen, Herbivores (lemmings, voles, caribou), Carnivores (arctic foxes, wolves, polar bears), Migratory Birds (ravens, snow buntings, falcons, loons), Insects (mosquitoes, flies, moths, grasshoppers), Fish

Answer:
The statement 2 best describes the next process taking place within the cell.
Explanation:
A kind of cell division, which is characterized by the differentiation of a single parent cell into two daughter cells that comprise equivalent chromosomes number is termed as mitosis or reductional division. In the given case, the arrangement of chromosomes at the equatorial plate indicates that the cell is currently in the metaphase stage of mitosis.
After going through the stage of metaphase, the cell moves into the anaphase stage. In the anaphase stage, the sister chromatids begin to segregate and move towards the opposite pole of the cell. Thus, statement 2 correctly illustrates the next stage of the cell.
Answer:
The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.
Explanation:
As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.
