The probability that allele k will drift to a frequency of 1.0 in the future is 0.5, given that genetic drift is a random and non-directional method of evolution that drastically modifies the gene or allele frequency in every population.

Genetic drift is the process by which a population's allele frequencies change over successive generations due to randomness (sampling error). It is more effective in smaller populations.

Since genetic drift is a random and ad hoc mechanism of evolution, its results are unpredictable. It's possible that it changes the frequencies of other alleles while keeping the fixed frequency of 1.0 for the allele k.

Two types of farming in Central America are Slash and burn Farming.

Define farming.

Managing a biological process, such cultivating crops or caring for livestock, in order to harvest products or reproduce a biological means of production, is often involved in farming, which is the typical activity that takes place on a farm.

Burn and slash Food is typically grown through agriculture, which involves clear-cutting wild or forested land and setting fire to any residual plants. The ash that results is nutrient-rich, helping to fertilize crops on the freshly cleared area.

A type of shifting cultivation is slash-and-burn, which refers to an agricultural system in which farmers frequently move from one cultivable area to another. Slash-and-burn agriculture is one of the only types of agriculture that can be used in tropical regions due to the leached soil, which is extremely nutritionally deficient in places like the Amazon. Instead of cultivating a single crop, slash-and-burn farmers typically plant a variety of crops, which increases biodiversity by fostering mosaic habitats. Other than a brief temporary patch, traditional slash-and-burn does not harm the ecosystem in its entirety. You could think of slash-and-burn farming as a type of agroforestry.

Generally CAP binds to it's site and recruits RNA polymerase for transcription from lac operon in the absence of glucose and presence of lactose, hence option A is correct.

Escherichia coli, a helpful gut bacteria, needs amino acids to survive because, like humans, it needs to make proteins. Tryptophan is also the amino acids they need. There is a set of genes which are known as the lac operon that was discovered in the E. coli bacteria and codes for the tryptophan biosynthesis enzymes. When tryptophan levels are low, the trp operon is expressed (or "turned on"), and when levels are high, it is repressed (or "shut off"). The trp repressor controls the trp operon. The trp repressor prevents the operon from being expressed when it is linked to tryptophan. Attenuation controls the synthesis of tryptophan as well (a mechanism based on coupling of transcription and translation).

The complete answer is:

A reflex, also known as a reflex action, is an involuntary, unplanned sequence or action that occurs in response to a stimulus. Reflexes of varying complexity can be found in organisms with a nervous system. A reflex is triggered by neural pathways in the nervous system known as reflex arcs. A stimulus causes a neural signal to be sent to a synapse. The signal is then transmitted across a synapse to a motor neuron, which causes the target response to be elicited. Because neural signals do not always reach the brain, many reflexes are automatic responses to stimuli that do not require or receive conscious thought.
