Identify the true statements regarding the heme group of myoglobin and hemoglobin

Biology
1 answer:
PIT_PIT [208]3 years ago
5 0
<span>The globin chains of myoglobin and hemoglobin prevent the oxidation of Fe2 to Fe3 , which irreversibly binds oxygen. The cooperativity of oxygen binding in hemoglobin arises from electronic interactions between heme groups.</span>

Cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell? if a cell at meta
kumpel [21]

Answer:

The correct answer would be 10.

The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and  mitosis (M) phase.

DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.

The number of chromatids restores to 2n in daughter cells after completion of mitosis.

Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.

Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.

In terms of adaptation, what advantage does sexual reproduction provide for species
KengaRu [80]
Unlike other ways of reproduction, sexual reproduction provides variation through inheriting various genes. This variation is essential for adaptation as it would not just create a copy of the original life form, but rather a different unique life form that could adapt to something, and then have it's own offspring with the adapted trait.

What does paleontology, biogeography, embryology, and anatomy reveal bout evolution
Ugo [173]

Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.

Biogeography deals with the distribution of species across the mother earth.

Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.

Anatomy deals with the study of the similarities and difference that exists among different species or organisms.

<u>Explanation: </u>

As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.

Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.
