It is also assists in creating body chemicals like hormones and enzymes that are needed for normal function. It provides energy (like carbohydratesdo) and keeps the immune system strong. Proteins are made up of amino acids, and dogs require 22 amino acids to make necessary proteins.

A gated channel in a cell membrane allows
Ne4ueva [31]
A gated channel is an example of facilitated diffusion. A gated channel protein is a transport protein that opens a "gate" allowing a molecule to pass through the membrane (usually molecules too big to enter the cell by passing through the membrane itself).<span> </span>Gated channels <span>have a binding site that is specific for a given molecule or ion. (meaning only certain molecules or ions can enter the channel).</span>

anzhelika [568]

Answer:

Lycopodium which is an example of Club mosses are seedless vascular plants that are heterosporous.

Explanation:

The club mosses, or phylum Lycopodiophyta, are the earliest group of seedless vascular plants. They can either be homosporous or heterosporous

Some club mosses like Lycopodium clavatum, sporangia are arranged in clusters called strobili.

Lycopodium is heterosporous (while some club mosses are homosporus.

Heterosporus means that spores of two different sizes and sexes are produced by the sporophytes of land plants.

A single-celled zygote develops into a multicellular organism with specialized cells through the processes of
iren2701 [21]

Answer:

mitosis

Explanation:

The zygote undergoes a process known as mitosis, in which it replicates its chromosomes (which carry each parent's DNA) and then divides, resulting in two identical cells. These cells are called totipotent and have the ability to develop into a new organism

You first use PCR to amplify the fragment so that there is sufficient DNA for sequencing. You carry out dideoxy sequencing and t
dsp73

Answer:

The first attached figure below shows the design of an agarose gel with four sequencing reactions. The second figure presents a photo of an agarose gel, so that you can better understand how the bands are represented in this gel.

Explanation:

To view the bands of four sequencing reactions on an agarose gel, you will need to use a melted agarose gel, plastic combs suitable for that reaction and a container suitable for that type of gel. You will place the plastic combs in the container and pour all the gel into the vat and wait for the melted gel to solidify. The plastic combs will form holes in the hardened gel where the DNA samples will be placed.

Once the gel is hardened, you will remove the plastic combs and begin to apply the sequenced DNA.

The sequenced DNA samples will be mixed with a dye, usually bromophenol blue, which will allow you to visualize the bands formed on the gel. You will also apply the dye to a sample without DNA containing only the dye, which serves as a comparison for the size of the bands.

Each sample of DNA will be plated in the column of holes formed by the plastic combs. Then, this container, with the gel, will be placed in a larger container that contains a loading buffer. The larger container will be closed and an electric field will be applied that will force the DNA samples to be moved from one pole to another inside the container, in this case, the samples leave the negative pole for the positive pole.

After a few minutes, it is possible to visualize the DNA displacement and at the end of the procedure it will be possible to visualize the formation of bands as shown in the drawing and in the figure below. The size of these bands can be compared and analyzed.

Which statement correctly compares the transfer of genetic material during mitosis and meiosis?
guajiro [1.7K]

<span>d. During mitosis daughter cells receive an exact copy of the parent cells and during meiosis it only receives half of the genetic material.

</span><span>Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. </span>
