Answer:
Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.
The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.
Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.
For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
Darwin's evolution theory explains organisms change accordingly.
Explanation:
Darwin traveled the world sitting on a five year voyage , during his journey he collected various species of plants as well as animals. He also came across three different types of diversity that are globally, locally, species overtime. Darwin said as earth is an oldest planet various changes have occurred from and still going on in present. Darwin said Farmers choose organisms based on traits and humans choose base on their needs. Four things essential for natural selection are competition, adaptation, variation, fitness.
Answer:
1600 calories consumed daily
Explanation:
we have to:
1 pound of weight (0.45 kg) equals 3,500 calories.
paraelll we suppose the formula
calories / days of the week = 3500/7 = 500 calories per day.
so there are 500 calories that you must reduce from the diet, so according to calorie consumption:
2100-500 = 1600 calories consumed daily
Answer:
I think 2 because that sounds like more of a consequence of the environment
