Answer: Wind speed and air temperature.


Wind chill factor is a factor which measures the loss of heat from the body due to the effect of low temperature air to which the body is exposed. This heat loss can be calculated by combination of factors like wind speed and air temperature that can be used to converted to a wind chill equivalent temperature or wind chill temperature. Higher the wind speed more will be the heat loss and lower the air temperature faster will be the cooling of the body. Therefore, wind speed and air temperature are considered for calculating the wind chill factor.

djyliett [7]

Answer;

A) Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic.

Explanation;

-Inductive reasoning is a logical process in which multiple premises, all believed true or found true most of the time, are combined to obtain a specific conclusion.

-The inductive method starts with many observations of nature, with the goal of finding a few, powerful statements about how nature works (laws and theories). In the deductive method, logic is the authority.

What is the determining factor for the transcription of structural genes of the trp operon?
padilas [110]

The right answer is 3. the availability of tryptophan in the environment

The TRP operon regulation depends on the availability of the tryptophan molecule (it depends if the cell need tryptophan or already has it).

There are two modes of regulation of the trp operon: Suppression and Mitigation

*Repression

The synthesis of operon mRNA is controlled by a repressor that blocks transcription when bound by tryptophan, which acts as a co-repressor.

The repressor, a 108 aa homodimer (ie 2 apo-repressor), has helix-turn-helix domains that interact with inverted repeats at the major groove of the operator, thus allowing its fixation.

In the absence of trp, the repressor is inactive and does not attach to the operator. The RNA polymerase can bind to the promoter and transcribe the trp E, D, C, B, A structural genes.

In the presence of trp, the repressor changes conformation and becomes active, so it binds to the operator, preventing RNA polymerase from accessing the promoter so transcription will not occur.

* The Attenuation

This is a premature termination of transcription that is a function of Trp concentration. It takes place at a late moment of transcription while regulation by repression is done during the initiation.

1st Case: Low Trp Rate, Continuous Transcription, → Formation of the Anti-attenuator in the absence of trp, and therefore the synthesis of tryptophan is continued.

2nd case: High rate of trp, stop transcription, → Formation of the attenuator in the presence of trp. This one will attenuate the synthesis of tryptophan.

AnnyKZ [126]

Answer:

gene flow

Explanation:

Gene flow, in simple terms, is a transfer of gene from one population to another. Also called as migration, where there is movement of individuals, and the genetic material they carry from one population to another. It also involves successful breeding of these individuals in their new locations. When people with sickle cell anemia were brought into the US, transfer of the gene responsible for sickle cell disease changed the frequency of the sickle cell allele in overall US population.
