nitrogen deficiency in low-nitrogen soils

pathogens transmitted by insects

Answer all of them please

Bryophyllum daigremontianum ("mother of thousands") produces hundreds of asexual baby plantlets that are genetically identical to the parent plant and can grow into mature plants. Predict whether plantlets obtained from a single parent plant but grown under different environmental conditions would likely show the same phenotypes.

Even though the plantlets are genetically identical, they would likely show different phenotypes because of phenotypic plasticity.

Although the plantlets start out genetically identical, different mutations in the different plantlets would result in different phenotypes under different environmental conditions.

The offspring are all genetically identical, so they would likely show almost the same phenotypes under different environmental conditions.

Since the plantlets are all genetically identical, they will only survive under the same environmental conditions as the parent, so the ones that survive will have the same phenotype as the parent

Why is nitrogen fixation an essential process?

Nitrogen fixation can only be done by certain prokaryotes.

Nitrogen fixers are sometimes symbiotic with legumes.

Nitrogen fixation is very expensive in terms of metabolic energy.

Nitrogen-fixing capacity can be genetically engineered.

Fixed nitrogen is often the limiting factor in plant growth.
