Answer:
1. During meiosis, we have three chromosomes +, +, ey, when duplicating them in sister chromatids we will have the combination ++, ++, eyey, then multiple alignments are made to generate the metaphase, the pairs will be randomly joined and the odd will be left couple, two of the three arrangements will be added and will generate two sperm + ey and two +, on the other side 2 with ++ and 2 with ey will be produced, thus the genotypes will be the following:
1/3 +
1/3 hey
1/6 ++
1/6 hey
2.
to evaluate the probabilities of the genotype e and when crossing the spermatozoa already studied it will be the following
1/6 ++ hey
1/6 eyey
1/3 + eyey
1/3 + hey
With this result we can deduce that 1/6 will not have eyes and 5/6 are wild type, which supposes that there is no crossing and that wild flies have the genotype + eyey
<span>It is through whistles that dolphins interact with the pod. Each dolphin has a distinct whistle that identifies it with other dolphins of its pod. If an individual is in danger, it uses a particular noise that indicates aid is needed, so the pod responds quickly.

Small dolphin species gather into multi-member pods as a way to compensate for their size when facing predators.</span>
Answer:
The answer is A.
Explanation:
Because B is easily disproven because they do not always spend their whole life on land. C is incorrect because most species of birds to not spend their lives in water. And D is wrong because both of their young develop in eggs.
Answer:
The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.
It was for studying MIMICRY in snakes.
Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.
This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.
The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.
since it changes in the artificial snake
