Answer:
ALL OF THE ABOVE
Explanation:
Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics. Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.
While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.
Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.
Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.
All these causes are related and therefore affects the Florida Panther.
C is the proper answer. They have been reduced by using unleaded gasoline because lead can harm the air and water we breathe, so using less of it will help reduce the pollution being caused by it.
Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of about 90% of all plants.
Mycorrhizal fungi are a symbiotic combination of fungi and plants. The term mycorrhiza refers to the role of fungi in a plant's rhizome, its root system. Mycorrhizae play an important role in plant nutrition, soil biology, and soil chemistry.
In mycorrhizal organization, the fungus resides in the root tissues of the host plant, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in extrinsic fungi.
The association is sometimes reciprocal. In some species or in specific cases, mycorrhizal fungi may have a parasitic association with the host plant.
Mycorrhizae are generally divided into ectomycorrhizae and endomycorrhizae. These two types are distinguished by the fact that mycelium of mycorrhizal fungi does not penetrate individual root cells while mycelium of endophytic fungi penetrates the cell wall and penetrates the cell membrane.

Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
