Answer:
The water molecules in ice are considerably far apart as compared to cold water of 4 degrees centigrade and below. This, therefore, makes ice less dense than water at these temperatures (because they are fewer water molecules in ice per unit volume). This is why ice floats on cold water below 4 degrees centigrade. Ice, being a bad conductor of heat, shields the water below an ice sheet from excessive heat loss to the atmosphere. This is why water remains liquid below an ice sheet protecting the marine life below from complete freezing.
I am so confused, what's your question?
The statement that organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to their offspring is false. Organisms pass their traits and adaptation abilities to their offspring. These organisms have also characteristics that are advantageous for reproduction in a specific environment and leave more offspring in the next generation. The process is called natural selection.
Answer:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b: Progeny ratio= 1: 1: 1: 1
c: 1/4
Explanation:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.
Gametes formed by female parent: All gametes with "bn" alleles.
c. The probability that the offspring will have a genotype of Bbnn=
Bb x bb= 1/2 Bb: 1/2 bb
Nn x nn= 1/2 Nn: 1/2 nn
Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.
For telophase it’s the end of mitosis and meiosis. And telomeres are basically caps at the end of your DNA to protect it.
