Explain how corn can be used as an example of Mendel's law of independent assortment.
MatroZZZ [7]

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.

Choose a plant or animal that you think is interesting. describe some of the threats or challenges
Natasha_Volkova [10]

Answer:

If I were to choose a plant or animal which is interesting, I'd choose the "cactus."

Explanation:

A "cactus" is truly a splendid plant owing to its <em>ability to survive in the desert </em>or<em> periods of drought.</em> Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.

  • One of these threats is the <em>"over-collection of cacti." </em>Due to its versatile use, the cactus is often sold as an ornamental plant.
  • Another threat is the number of pests, such as <u>snails</u> and<u> slugs</u>, that attacks it yearly. It is a delicious food for<em> mealy bugs, red spider mites, gnats, flies, etc.</em>
  • People often misunderstand the <u>cactus' water level need</u>s. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.
