Biology
1 answer:
Sphinxa [80]2 years ago

The major difference between bacterial chromosomes and eukaryotic chromosomes is that bacteria have a single circular chromosome whereas eukaryotes have several linear chromosomes.

Eukaryotic chromosomes are present within the nucleus while prokaryotic chromosomes are found in the nucleoid (a region of the cytoplasm). The nucleoid does not have a membrane.

In eukaryotic chromosomes, DNA is wrapped around histone proteins, which is further compacted by supercoiling and folding. However, in prokaryotic chromosomes, DNA is supercoiled and held together by nucleoid-associated proteins.

Prokaryotic chromosome is very simple in comparison to the eukaryotic one. Prokaryotic chromosome lack telomeres and centromeres sequences which is found in the eukaryotic chromosomes.

How does a white blood cells structure help it perform its function?
Kryger [21]
Hi
<span>Firstly, the white blood cells tend to have a higher surface to volume ratio then other cells because the are more amorphous. That would lead to an relative increase in plasma membrane, which contains receptors for identifying antigens. Thats why, the white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration. It's basically because this.</span>

zloy xaker [14]

D)Heat within Earth

Explanation:

The heat from within the earth is as a result of plate tectonics. Plates on the earth are driven by heat within the earth through convection currents.

  • Plate tectonics suggests that the earth are broken into slabs that moves on the weak and ductile material called asthenosphere.
  • Heat from within the earth causes the melting of asthenosphere.
  • The riding lithosphere which is cold will sink into the asthenoshpere.
  • Hot mantle materials will move to the surface thereby setting up a convection current.
  • Heat from within the earth rises to the surface due to plate movement.

In most sexually reproducing organisms, the diploid phase of the life cycle begins at
valkas [14]

The diploid phase of the life cycle begins with the formation of the zygote.

Meiosis is referred to the type of cell division which occurs in the production

of male and female sex cells. This also occurs during sexual reproduction.

Parent cells provide male and sex cells such as sperm and egg which

contains DNA. They then fuse together to form a zygote which is the diploid

phase as a result of the fusion of two haploid cells. The zygote then

continues to undergo some meiotic processes which reduces it to back to a

haploid cell and consequent growth to form a fetus.
