Answer:
B. Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.
Explanation:
- Multiple alleles are an alternative form of allies and can occupy the same gene ad only two of them can be found in the same organism. Such as the ABO blood group.
- A polygenic or a multiple gene inheritance is a hypothetical gene that s often difficult to characterize and traits control a multiple of genetic loci, they are relatively small and interchangeable.
Mitochondria convert the energy in the bonds of glucose and oxygen to readily available energy in the form of ATP (Adinoshin Tri Phosphate) with the help of oxygen. Mitochondria are often referred to as the powerhouse of cell.
Answer: A. Zidovudine (Retrovir) and emtricitabine (Emtriva)
Explanation:
Basic postexposure prophylaxis (PEP) therapy typically includes treatment with one of these combinations of pharmacologic agents:
Zidovudine (Retrovir) and emtricitabine Emtriva),
Lamivudine (Epivir) and tenofovir (Viread), or
Tenofovir (Viread) and emtricitabine (Emtriva)
If the accidental exposure is especially severe, a third agent may be included.
Answer:
Notice that many amino acids are represented in the table by more than one codon. For instance, there are six different ways to "write" leucine in the language of mRNA (see if you can find all six).An important point about the genetic code is that it's universal. That is, with minor exceptions, virtually all species (from bacteria to you!) use the genetic code shown above for protein synthesis.
Explanation:
The seahorse is found in many different locations around North and South America. They are typically located in the shallow tropical waters that are quite warm. They will be found living along the coral, the sea grass, and the mangroves. In Europe they are known to reside in the Thames estuary. Many of the larger species are living in the Mediterranean Sea.
Many species of seahorses are very territorial. The males often have about 11 square feet of territory. The females have up to 1,100 square feet. What they live though will influence how much area they have. In many regions that habitat range has gotten smaller and smaller.
In captivity the seahorses will be limited to a large aquarium. This can be a huge change in home range habitat for them. That is why the stress levels are very high and the survival rate low. Young in a captive state are more likely to do well because they haven’t become accustomed to the wide territory.
As a result the seahorses living in a given area have become more aggressive. They have also suffered from higher stress levels and more forms of disease. The aggressive behavior is typically when males are looking for females that they can mate with. It is also common when they are fighting for territory or food and that extends to both genders.
