Answer:

Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

7. Phytochrome prevents seeds of some plants from germinating when they are in deep shade by the: absorption of far-red waveleng

SIZIF [17.4K]

<h2>Function of Phytochrome </h2>

Explanation:

The color of light that they absorb maximally by the two types such as Pfr is a blue-green structure that ingests far-red light (730 nm) and Pr is a blue structure that retains red light (660 nm)
Pfr assimilates far-red light, it is changed over to the Pr structure
Pfr can spontaneously revert to the Pr form structure in obscurity dark over time = dark reversion Pfr is additionally helpless to proteinases
Pfr contains some red light, so in red light 15% Pr and there is a parity of 85% Pfr.
The phytochrome (Pr) is changed over to the organically dynamic structure red light with the Pfr under illumination
Darkness and Far -red light convert the particle back to the inactive form.

HELP!! DNA was isolated from water samples taken from six different sites. This gel

VladimirAG [237]

After running DNA in a gel, bands of different sizes and species might appear. Scientists know silver carp are at North Shore site 1 because one of the bands in lane 1 matches a band in the positive control (Option C).

When DNA was isolated and run in a gel, many bands migrated to different points.

These bands were the different-sized fragments of DNA samples from different species from the six sites.

Researchers wanted to figure out where the silver carp is.

To do it, they needed to identify the bands on the gel that belonged to the silver carp DNA, so they included negative and positive controls to make comparisons.

<h3>Positive and negative Controls</h3>

Negative and positive controls guarantee the interpretations of the results.

The positive control shows the band sizes that belong to the silver carp DNA.

Any band in the sampling sites that matches one of the positive control bands indicates that the species is present at that site.

The negative control is the opposite. It is the absence of the species' DNA.

<h3>Results interpretation</h3>

As we can see, there are four sites where the bands match one of the bands of the positive control. These are,

North shore site 1
Chicago site 1
Calumet site 1
Calumet site 2

This means that at these four sites, the silver carp is present.

So scientists know silver carp are at North Shore site 1 because one of the bands in lane 1 matches a band in the positive control (Option C).

By looking at the lane of the North Shore site 1, we can also see another band (Thinner and grey). But this band does not match either of the positive control bands. This result suggests that the grey band belongs to another species' DNA.

Vertebrate locomotion results from the contraction of muscles anchored to what other tissue?

liraira [26]

Answer:

Bones

Explanation:

Bones are tissues that provide the body with rigidity. It also acts as the body's supporting structure.

The bone helps to maintain the body's shape at all times and provide a surface for the attachment of muscles. Joints are the points of contact between two bones. The bones, muscles and joints are very important in the locomotion(movement) process because there’s a synergy between them.
