The answer is Dr Alec Jeffreys. <span>The genetic fingerprint and DNA profile are used by forensic science to help the police in their research work. The same technique has proved very useful in resolving litigation about paternity, for the identification of human remains in armed conflicts and for the identification of the corpses of historical figures.</span>
<span>Men can produce sperm throughout their adulthood because their reproductive organs and glands are fully developed. During their childhood and adolescence the glands and organs are not functional for reproductive purposes.</span>
Answer:
Explanation:
The production of ATPs for skeletal muscle contraction depends on the conditions that the muscles are exposed to.
In presence of abundant oxygen, to the cells Aerobic respiration-cellular respiration is the most ideal. 32 ATPs and 4 C02 are produced as by-products during the process as by products majorly two C02 from each of the 2 acetyl Co A that enters the kerb's cycle.
Likewise direct phosphoryaltion of ADP to ATP gives 32.0 kj/mol of heat liberated but no C02 was produced. This takes place during chemiosmosis. with 28ATPs produced.
In absence of oxygen, anaerobic respiration of skeletal muscles produced ATPs from glycolysis, heat and 2C<u>02 as products, but not as by-product</u>.Through alcoholic fermentation pathway.
Therefore ,the correct answer is Aerobic respiration, because it gives out C02 which is a by-product, released out of the body as waste from the lungs,and not use up in the body.
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Crustacea(ns) form a very large group of arthropods.
