1 answer:

8 0

The arctic hare lives in the harsh environment of the North American tundra. These hares do not hibernate, but survive the dangerous cold with a number of behavioral and physiological adaptations. They sport thick fur and enjoy a low surface area to volume ratio that conserves body heat, most evident in their shortened ears. These hares sometimes dig shelters in snow and huddle together to share warmth.

Because all of the cells in a multi-cellular organism come from a single cell, all of its cells will have the same number of

Lapatulllka [165]

Answer:

Chromosomes

Explanation:

Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.

Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.

Suppose two BbCc mice are crossed together. Assuming that the two genes assort independently, what are the expected phenotypes,

Katyanochek1 [597]

Answer:

4 types of phenotypes with phenotypic ratio 9:3:3:1 will be obtained.

Explanation:

The Punnett square diagram for the cross between mice with genotype BbCc & BbCc is attached.

It is clear from the diagram attached that the phenotypic ratio will be 9:3:3:1

The following 9 genotypes will show dominant trait for both the characters i.e. characters represented by B & C genes.

BBCC, BBCc, BbCC, BbCc, BBCc, BbCc, BbCC, BbCc, BbCc

The following 3 genotypes will show dominant trait for one character represented by gene B and recessive trait for other character represented by gene C.

BBcc, Bbcc, Bbcc

The following 3 genotypes will show recessive trait for one character represented by gene B and dominant trait for other character represented by gene C.

bbCC, bbCc, bbCc

The following genotype is the only genotype which will show recessive trait for both the characters represented by gene B & C.

bbcc

-3(x-5)=45. could anyone tell me how to do this prob and the answer☺ btw this is mathematics

valkas [14]

Youre using the distributive property. sk you multiply negative three by x and negative 5. itt equals negative three x and positive 15. you subtract 15 frkm 45. which leaves 30. then you divide by negative three. the answer is negative ten.
