Answer:

Abiotic-  non-living thing. ex: wind,water,soil,sun, atmosphere, temperature

biotic- living components of an ecosystem ex: animals, plants, bacteria, fungus

Energy is passed between organisms through the food chain. it first starts with the producers which get eaten by the primary consumers. than the secondary consumers eat them.

Genetic drift results in selection for individuals that are better adapted to their environments. True False
Harlamova29_29 [7]

Answer: False.

Genetic drift is a stochastic process that occurs randomly through time. It refers to random fluctuations in allele frequencies due to chance events (small population size).

Explanation: Factors that can affect genetic diversity are Genetic drift, mutation, selection, migration, non-random mating and recombination.

Of these factors, forces that majorly control the fate of genetic variation in populations are genetic drift and natural selection.

Genetic drift refers to random fluctuations in allele frequencies due to chance events (small population size).

Natural selection involves environmental conditions acting on wild plant or animal populations or species. Most fit in a selection refers to genotype or phenotype with greater average reproductive output over it's lifespan than other genotypes or phenotypes.

The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no oth
KIM [24]

Answer:

The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.

Explanation:

Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.  

With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.

What is recombination
Rufina [12.5K]

Answer:

Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
