How could the tomato plants response to being eaten by a hornworm caterpillar be described as a function of homeostasis
sesenic [268]

Answer:

First, it's important to get clear on the meaning of Homeostasis.

In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.

       

Explanation:

In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.

This does not mean that the plant or animal is completely immune to such external changes.

In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.

Cheers!

DNA _____.
Ne4ueva [31]

Answer:

Answer:

The correct answer would be "contains coded information for the creation of proteins".

DNA or deoxyribonucleic acid is a polymer of nucleotides.

It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.

In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.

The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.

It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.
