Answer:

The level of compaction in Eukaryotes from naked DNA to the most compact is:

d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome

Explanation:

As we know that the

  • Diameter of  DNA is 2 nm.
  • Diameter of nucleosome is 11 nm.
  • Diameter of solenoid is 30 nm.
  • Diameter of looped chromation is 300 nm
  • Diameter of meta-phase chromosome is 1400 nm

All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.

Blababa [14]

Answer:

A homozygous dominant trait can be described as a trait in which both the alleles of a gene are the dominant one. For example, the AA genotype of the 80 brown gerbils.

A heterozygous trait can be described as the trait in which one of the alleles is dominant and the other is recessive. For example, the Aa genotype of the 64 brown gerbils.

A recessive trait can be described as a trait in which both the alleles are recessive. For example, the aa genotype of the black gerbils.

saw5 [17]

Answer: Autocrine signal, paracrine signal and endocrine signal.

Explanation:

Testosterone is an example of hormone which shows its effect on different locations of the cells.

The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.

Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.

The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.

All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.
