Many plants have evolved mutualistic relationships with nitrogen-fixing bacteria because: A. The bacteria transform nitrogen into useful forms for the plants; the plants provide carbohydrates B. The bacteria protect the plant from harmful effects of nitrogen compounds such as ammonia; the plants provide carbohydrates for the bacteria C. The bacteria utilize nitrogen to produce energy for the plants; the plants provide the source of the nitrogen for the bacteria D. The bacteria provide natural immunities to the plants; the plants shelter the bacteria from predators E. There is not a mutualistic relationship between nitrogen-fixing bacteria and plants

Plants have evolved mutualistic relationships with nitrogen-fixing bacteria

because the bacteria transform nitrogen into useful forms for the plants and

the plants provide carbohydrates.

Plants and bacteria have developed a mutualistic behavior known as

symbiosis as they gain benefits from each other.

The bacteria which is usually found in the root nodule helps to convert

nitrogen into useful forms while the plants provide carbohydrates to the

organisms for their activities and survival.

A

Explanation:

Different or same species interact with one another in an ecological relationship. One of these ecological relationships is MUTUALISM, in which both organisms involved in the relationship benefits from it by helping one another fulfil a task they normally can't fulfil on their own.

An example of this mutualistic relationship is that of nitrogen-fixing bacteria in the root nodules of certain plants. In this relationship, the bacteria uses its ability to fix nitrogen compounds to help plants convert nitrogen gas into compound forms (ammonia, nitrate) that will be used for their structural build up e.g amino acid formation while the plant uses its photosynthetic ability to produce carbohydrates in form of malate and succinate for the bacteria.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

answer: dna

because all cells have genes
