Answer:
2. Can carry less oxygen and more carbon dioxide.
Explanation:
Sickle cell anemia damages and inhibits hemoglobin in red blood cells reducing how much oxygen they can carry.
Translation. The tRNA brings the corresponding amino acids to the ribosome.
desert, open ocean, lake, tropical rain forest
Explanation:
The net primary productivity tells us about how productive an ecosystem is. It is usually derived by the difference between the amount of carbon dioxide that producers used to the amount they release during their cellular respiration.
- The rainforest is the biome with the highest amount of net productivity.
- The amount of sunlight and organic matter used up during photosynthesis is very large.
- The tropical rain forest receives the highest amount of sunlight because the sun is overhead here.
- This provides energy to drive photosynthetic process in the presence of other available resources.
- Deserts are bare and lacks plants due to the extreme conditions here not favorable to life.
- The open ocean productivity is restricted to the photic zone where light is only able to reach
- Lakes are highly productive ecosystems.

Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists. For example, one may never see a person with blue eyes and brown hair if the alleles for the two traits, hair and eye color, were inherited together. However, it is worth noting that there is "genetic linkage", meaning full or partial violation of independent assortment among certain trait groups.
There are 46 chromosome in a normal human diploid cell, 23 inherited from the mother's egg and 23 inherited from the father's sperm.
