The answer is (d.) Some scientists believe that prions, tiny proteins much smaller than a cell, that can replicate themselves may be living organisms.
Prions are like viruses, they are not alive making statement B to be true. Prions lack the ability to grow and reproduce. they are dependent on the living cells to replicate. Statement A is absolutely correct while Statement C is somehow wrong. According to scientists, the accurate count of cells in a human is 37.2 Trillion.
There are 75% chances that their offsprings will be checkered.
Explanation:
The gene version allele is received by an individual and if they are different then the gene of the parent which is dominating is expressed in the offspring. However, in the case of co dominance the offspring gets the trait of both parent alleles.
So, in this case the mating of checkered rooster and checkered hen with co-dominance in their trait of genes will produce checkered offspring with a chance of 75 percent as can be calculated by the punnet square. The result will be 3 out of 4 checkered offspring.
<span>This type of a relationship where only one species benefits and the other is harmed is known as parasitism. The other species is not killed immediately, at least not as long as the first species, or the parasite, needs them. As long as the victim provides enough sustenance for the parasite to live, they will be necessary and not killed off. The moment the victim has nothing else to offer to the parasite, it is probably going to die.</span><span />
Domain is basically your (X) value.
Ex: (3,7) 3 would be your domain because it is the x value.
Answer:
selective breeding always produces unhealthy offspring
Explanation:
false becasue its mostly healthy and dominant genes
