What is adaptation in animals and plants

Answers

Adaptation is when a plant or animal make modifications to their body to survive in an altered environment. For example, the snow foxes' fur changes depending on the seasons. Another example would be blueberries. They develop thorns in order to protect the berries the plant grows.
Pretty much all plants adapt. If you pay attention, when you put a plant next to the window, and when there's no sunlight shining on it, you should notice that it will start to lean toward the sun.
Hope I helped!

Adaptation is a modified part of the animal that it was born with to survive in certain a certain way that it was suppose to survive. For example, Ducks have webbed feet, so they can swim. That is an example of an adaptive animal.

Some animals, such as cows, normally produce only one offspring from each mating. If a cow showed a dominant phenotype, why would a typical testcross be a difficult way to determine the genotype of that animal?

Answers

Answer:

Because of insufficient number of offsprings to determine the result of test cross.

Explanation:

Normally, in genetics, a test cross is a cross between a dominant phenotype (genotype unknown) and a homozygous recessive genotype in order to determine the genotype of that dominant organism.

The result of the test cross is obtained when a 1:1 phenotypic ratio is produced for each trait i.e. 1 dominant trait: 1 recessive trait showing that the parent is heterozygous while all the offsprings will show dominant traits if the dominant phenotype was homozygous. Hence, more than one offspring is required to be able to conclude

In this question, the cow only produce one offspring which may be DOMINANT for the observed trait making it difficult to know if other offsprings will all be dominant or some of them recessive. Hence, it is not a sufficient number needed to determine the genotype from the phenotypic ratio of offsprings.
