Answer:
In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia
.
Explanation:
A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.
Answer:
B)Photosynthesis releases oxygen into the atmosphere while aerobic respiration removes oxygen from the atmosphere.
Explanation:
Only option B satisfies the answer to the question.
We know that photosynthesis is the process whereby green plants manufacture their foods in the presence of carbon dioxide and sunlight. Carbondioxie in the environment is used to manufacture food in plants. The bye product of photosynthesis is oxygen gas. Oxygen gas is used for aerobic respiration in animals and is essential for their life. This way photosynthesis adds to the pool of oxygen in the atmosphere and aerobic respiration removes from the pool.
<span>All of the populations of different species that occupy and are adapted to a given area are referred as a community.
In a community, there will be many populations of different species. Population is a group of individual in a certain area. The more species in the community, the more complex it is.</span>
