Birds are animals that have wings to fly, which can be adapted (modified) to regions where winds are more intense.

<h3>What is adaptation?</h3>

Adaptation refers to the emergence of traits capable of facing challenging environmental conditions.

In birds, wings are an adaptive trait of this taxonomic group, which can be modified according to the environment.

In regions where winds are more intense, wings can take different anatomical forms in order to resist these environmental conditions.

A gene that is normally transcriptionally active can be "silenced" if it is relocated (through experimental manipulation) to cer
Genrish500 [490]

Answer:

Position Effect

Explanation:

Position effect is referred to the effect on gene expression when the gene is translocated from the location it is on a chromosome to another location.

As it relates to gene silencing and euchromatic gene repositioning, Position effect variegation best explains it.

Position effect variegation occurs when a gene in some cells is silenced as a result  of rearrangement of chromosomes which translocate or reposition euchromatic genes close to vicinity of heterochomatin. It is this abnormal chromosomal juxtaposition that leads to the gene silencing in stochastic pattern.

el electrophoresis is normally set up with the negative electrode at the top of the gel and the positive electrode at the bottom
Marina CMI [18]

Answer:

The DNA will still move towards the positive electrode

Explanation:

Gel electrophoresis is a technique which is used by the molecular biologist to separate the fragments of DNA. In the procedure, a DNA sample of a particular concentration of DNA sample composed of a particular length of DNA is loaded into the samples.

The gel is usually set up with the positive electrode at the bottom and negative at the top which by mistake when placed at the bottom and positive at the top.

The DNA will still move from the DNA wells towards the positive side as the DNA moves in the gel as the DNA posses negative charge due to phosphate groups they have and therefore move towards the positive electrode (opposite charge always).

Thus, the DNA will still move towards the positive electrode is correct.

Page No Date Sex in bacteria is deteaimined by ?<br>​
VladimirAG [237]

Answer:

Pili

Explanation:

The sex of bacteria is determined by a structure called Pilli. Pilli is not present in all species of bacteria, but within species that have this structure, such as Escherichia coli, pilli is considered an appendage present in male bacteria.

Pilli presents itself as a long hair and can also be called F factor or fertility factor and has a reproductive function, as it allows the conjunction between two bacteria (one with pili and the other without), where the male bacteria transmit genetic resources to within the body of the female bacteria , which will combine these resources with its own resources and will give rise to another bacteria.
