What is a list of types of organisms in an eco pyramid?

Next the researchers repeated the experiment in part c but instead of mixing the ax and ay strains, they put one strain on each

Nadya [2.5K]

The correct answer is none of the above.

Bacterial cells can transfer genetic material through a process called bacterial conjugation. This process involves the direct physical contact of the bacterial cells and a horizontal gene transfer. The genes which are transferred are most of the times beneficial for the recipient, such as genes for antibiotic resistance.

In this example, bacterial cells cannot have physical contact, since they are separated by a glass filter. Therefore, the bacterial conjugation cannot happen. Given that no gene transfer can be achieved, the AY strain remains bio- trp- and is unable to grow on any medium that lacks bio or/and trp.

A signal molecule in the interstitial fluid binds to a receptor on the cell membrane, triggering an intracellular cascade. Which

Lady bird [3.3K]

<h2>Function of The Cell Membrane</h2>

Explanation:

There are a few unique kinds of this simple development of particles. It could be as basic as atoms moving uninhibitedly, for example, assimilation or dispersion.
Proteins are utilized to help move atoms all the more rapidly. It is a procedure called encouraged dispersion.
It could be as straightforward as acquiring a glucose particle. Since the cell film won't permit glucose to cross by dispersion.
The cells are in a zone where there is a huge focus contrast. For instance, oxygen particle focuses could be exceptionally high outside of the cell and extremely low inside.
Those oxygen particles are little to such an extent that they can cross the lipid bilayer and enter the cell.
This is a water explicit procedure. For the most part, cells are in a domain where there is one convergence of particles outside and one inside.
Since focuses like to be the equivalent, the cell can siphon particles in an out to remain alive. Assimilation is the development of water over the layer

Acid rain is a secondary pollutant. Please select the best answer from the choices provided T F

olchik [2.2K]

The answer is T, True. Secondary pollutants are pollutants that we do not directly release, but that are created as a side effect of releasing primary pollutants, such as carbon dioxide, sulfur oxides, and particles such as ash and dust. Secondary pollutants include acid rain, ozone, smog, and CFC's (chlorofluorocarbons).

If an organism is homozygous for a particular trait, the organism A. has extra alleles on both chromosomes in a chromosome pair.

inysia [295]

B. Has the same allele on both chromosomes in a chromosome pair.

Here is why:

Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.

There can be two types of homozygous alleles.

~

Homozygous Dominant: BB

Homozygous Recessive: bb

Notice in both of these they were the same alleles.

~

Heterozygous: Bb

Notice how both are different alleles.

~

Below I have attached a diagram of a Punnett square I have made.

On the left is a homozygous recessive allele pair.

On the top is a heterozygous allele pair.

Organisms depend on , which are compounds that stabilize ph by absorbing or releasing h ions.

Korolek [52]

Organisms depend on buffer that are compounds that stabilize pH by absorbing or releasing h ions. It consists of weak acids and weak bases.

The buffer is also consists of undissociated acid (HA) and the ions that are made by dissociating the acid (A-). Because of the presence of weak acids and bases and to stabilize the pH the buffer absorb or give off H+.

The nucleic acids must have positive charge that helps in formation of double helices.

Undissociated acid means when an acid dissociates to release a proton to make the solution acidic.
