Answer:
If a species has the ability to produce that many eggs, that means it has the ability to overproduce. This is beneficial because while the parents cannot provide excessive amounts of parenting/care for each of the offspring, only the fittest will end up surviving. Once the fittest survive and reproduce, they will pass on the trait or traits that made them fitter to their offspring. Then the process will repeat, resulting in a better population over time. Thus, the amount of favorable traits will accumulate in the species; this, in other words, is a benefit to the species.
Answer:
Both parents would have to have one recessive gene.
Explanation:
Blond haired people have two recessive genes to have blond hair. Dark hair is dominant over blond hair. If B represents dark hair and b represents blond a person could have the two genes B and b. The dominant gene will win. For example: Bb produces dark hair. BB produces dark hair, but bb produces blond hair. Two blond haired people each will give a b characteristic to the offspring, producing blond hair. Two parents with Bb genes each have 1/2 chance of giving a b gene. Therefore two dark haired parents Bb have 1/4 chance of having a blond offspring. 1/2 times 1/2 gives 1/4 chance (if they have both the dominant and recessive genes).Two parents with BB can not have a blond haired offspring.
It would be the first option A) Mouse
Answer:
D) The exact mixture of components varies from point to point.
Explanation:
It's important to know that the air is a mixture formed by around 78% of nitrogen, 21% of oxygen, 0.9% of argon, 0.04% of carbon dioxide, and other gases in smaller amounts.
Additionally, the mixture that formed the air is not always the same, it variates depending on several variables, that means the air as such can slightly change is mixture, at some points can have a bit more oxygen or a bit more carbon dioxide. In other words, the air is not a constant mixture.
Having said that, the right answer is D, because the mixture of components can actually vary from point to point.
