Answer:
E
Explanation:
Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others
the principle is defined by the equation
p² + 2pq + q² = 1
where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq
substitute the value into the expression
p² + 0.04 + q² = 1; The information is not enough to calculate either p or q going by the equation generated.
A diet deficient in calcium can cause osteopenia. The deficiency of calcium may Cause a low bone density which is a condition caused in osteoporosis. Hence the correct answer is B osteopenia.
An invasive species is a species that is not native to a specific location, and that has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health.
The correct term to fill in the blank would be cortisol. In the context of stress hormones and the brain, cortisol has a profound effect on the hippocampus, a brain structure that plays a pivotal role in memory. Cortisol is classified as a steroid hormone which is produced by the adrenal gland. It is deemed as the stress hormone as it is released as a response to stress as part of the fight or flight process. From studies, cortisol was found to have effect on the hippocampus when present in high levels. It damage and kill the cells in that area of the brain. The hippocampus is the area of the brain that is responsible for the long term memory storage. So, when this part is damage then the storage for our memories would surely be affected.
Answer:
- Bird wings and dragonfly wings are both used for flight: Analogous structure
- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure
- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure
- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure
Explanation:
Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.
