Answer:
A. Codominance
Explanation:
Codominance is where both traits show, and in this case, with the red and blue, they show. Incomplete dominance is characterized by blending; in that case, the fish would have to be purple because red and blue make purple. It's not multiple alleles because there isn't anything to suggest that there are more than 2 alleles for the color gene.
Answer:
C. It harms aquatic organisms
Explanation:
The hydropower is a one of the most commonly used in the world. It is based on the power of the water, and by building a dam on a river, the water is accumulated, and its power used for production of electrical energy. While this type of power has lot of advantages, like having long lifespan, being eco-friendly, and it has high efficiency, it also has some negatives about it. The biggest negative by the hydropower is that it causes harm tot he aquatic organisms. Because there is a dam built, the water becomes more stagnant, meaning that it becomes warmer, harming the organisms that are not able to adapt to it. The dam restricts the migration of the aquatic organisms, which is especially a big problem for the ones that migrate because of mating. The nutrients start to concentrate in front of the dam, while after the dam they are in very low quantity.
I don't know the options, but if more then one lizards live in grass and have similar characteristics then I do believe it would "Adaptation" since they are adapting to live in that environment... my apologies if I am incorrect
Hope this helps!!!!
Answer:
The disease is autosomal dominant.
Explanation:
Huntigton's disease is an autosomal dominant disease because the allele for this disease is present on an autosomal chromosome and the person with even one mutated allele (H) can develop the disease even if he has one normal allele (h) too. If a person is affected with Huntigton's disease, there are 50 percent chances that the children will also suffer from the disease.
For example: A father is suffering from Huntigton's disease but mother is normal. Let us see how it will be passed to kids.
P1: Hh : hh
Gametes: H : h: h: h
Offspring: Hh: Hh: hh: hh
50% : 50%
Therefore, 50 percent chances are there that the kids will have disease even if only parent suffers from it.
