The answer is reproductive isolation. This ensures that there is no viable reproduction between
different species or subspecies. Even if reproduction
between species leads to conception, the embryo may not be able to survive to maturity or will be sterile. This ensures that
species remain integral by restricting gene flow.
the answer for the first one is B
and the second is B
Answer:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions
Explanation:
Genes are located in the same location on homologous chromosomes.
Answer:
P = 0.79.
Explanation:
To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).
Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.
If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.
To prove this, we can insert these values into the equation:
