The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
The statements are true.
Hemoglobin (Hb), is the oxygen-transport metalloprotein which contains iron in the centre of its structure. This metalloprotein is found in the red blood cells (erythrocytes). The function of hemoglobin is to transport the oxygen through the blood carries from the lungs to the rest of the tissues. Oxygen is necessary for the aerobic respiration in order to provide energy for the functions of the organism (metabolism).
Answer:
B
Explanation:
<em>The correct answer here would be that </em><em>it can be injected by a virus.</em>
Since a virus operates by taking over the genetic system of the host and uses its replication, transcription, and translation to make virions or viral particles through the lytic or lysogenic life cycle. In the process, if the virus is utilized as a vector to carry a foreign DNA, the DNA is introduced into the genome of the bacteria. This is exactly what happens during the process known as transduction.
<em>The correct option is, therefore, </em><em>B.</em>
Hydrogen and Oxygen. Better known as H2O
