In order to identify the most recent common ancestor of an animal, the physical and genetic makeup of the organisms must be compared. The two organisms must have striking similarities in order to be considered as closely related.
Despite the difference in their size, the domestic ferret has a great resemblance with the features of an Eastern European polecat. In addition, they have the ability to cross-breed with polecats. Therefore, the most recent ancestor of the ferret is the Eastern European polecat.
This took a long time to type cuz I am a slow typer. But I hope I got the answer correct! Hope you have a great day!:)
Answer:
Yes!
Explanation:
It is stated in the Unified Cell Theory by a Botanist named Schleiden and a Zoologist named Schwann that all Living Things (organisms) are composed of 1 or more cells. The cell is the basic unit of life.
Answer: For three traits inherited in a dominant/recessive pattern, the probability of an offspring in a trihybrid cross between parents heterozygous for all three traits to be recessive at exactly two of the three loci is 23/64.
Explanation: Let A, B and C represent the dominant alleles and a, b and c represent the recessive alleles. The genotype of each of the parent will be AaBbCc since it has been said to be heterozygous for all the three traits. There are eight (8) possible different types of gametes from each of the genotype. This can be calculated using 2^n where n is the number of heterozygous loci.
The number of heterozygous loci in the genotype AaBbCc is three (3). 2^3 = 8. The gametes are;
ABC
ABc
AbC
Abc
aBC
aBc
abC and
abc.
Therefore, sixty-four possible offsprings are expected from the cross AaBbCc x AaBbCc.
Out of these offsprings, twenty-three (23) are expected to be heterozygous at two loci as boldly shown in the attached image.
An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
