Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Answer:
You didn't include the following
however 2 heterozygotes
build a punnett square which is a just a box with the alleles contributing from each parent one on the top and one on the side
A a
A AA Aa
a Aa aa
That is what would happen so 25% chance of AA and 25% of aa and 50% chance of a heterozygote
Brainly won't allow the h o m o zygote to be included as an answer
Explanation:
Maintaining a courteous attitude while driving can be difficult yet there is a technique to have it.One is having a positive attitude. Examples would be being tolerant to other road users, forgiveness as well as recognition that people would make mistake. A sense of humor and a helpful attitude towards driver.
Explanation:
But two water molecules contain four hydrogen atoms, which means that two hydrogen molecules must be present on the reactant side of the equation for the numbers of H atoms to balance (Figure 7.2 on the previous page).
This phenomenon is not rare in the animal kingdom. Known as alternative mating strategies, it is employed by a subgroup of males that are usually incapable of facing the larger males in direct confrontations.
These "sneaky males" as they are sometimes called, will employ alternative strategies to mate with females. Which strategy will be dominant is dependent on the environmental factors and is not permanent. In some conditions where food is not that abundant, there will be less larger males and thus, the smaller males employing this strategy will be more common. At other times the opposite will occur.
However, in most cases and most probably here, the end result will be a coexistence of this traditional and alternative mating strategy, where males will exhibit a greater diversity in phenotype.
