Answer:

Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.

Biodiversity includes all ecosystems—managed or unmanaged.

Biodiversity is essentially everywhere, ubiquitous on Earth’s surface and in every drop of its bodies of water.

Which of these microbes has the most complex cell wall?

vivado [14]

Plant cells have what is perhaps the most complex outer coverings. Plant cell walls are made largely of cellulose which forms strong, highly rigid, almost indigestible coverings that protect the cell and gives it shape.

A researcher is trying to construct a molecular-based phylogeny of the entire animal kingdom. Assuming that none of the followin

densk [106]

Answer:

Option (B) is the correct answer of the following question.

Explanation:

Collagens are a family of enzymes that perpetuate and protect many of the body's tissues, with the exception of connective tissue, femur, fibula, pigmentation, and the caucasian eye (optic disc). It would be the best choice on which to base the phylogeny.

The first and most concentrated substance in the body is the collagen genes.

It is a large, indigestible cellular muscle which maintains organisms and gives internal cells a texture.

Collagen is also an essential part of the crisscrossing membrane neurons.

Other options are incorrect because they are not related to the given scenario.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation.

Lera25 [3.4K]

The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, T<u>T</u>C⇒T<u>G</u>C. Patient 2: nucleotide 143, T<u>T</u>C⇒T<u>C</u>C. Patient 3: nucleotide 147, TT<u>C</u> ⇒ TT<u>G</u>.

<h3>What is a mutation?</h3>

A mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual.

These mutations are the ones that have been selected by natural selection.

<h3>Solving the problem</h3>

We know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.

So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.

Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.

Finally, we will identify the nucleotide location of each mutation.

People who use complex tools like plows, irrigation, and fertilizers to grow domesticated plants are called:

motikmotik

People who use complex tools like plows, irrigation, and fertilizers to grow domesticated plants are called farmers, it is a large scale activity and it´s use to obtain food from the earth, we also have horticulture, does not require hundreds or thousands of acres of land, horticulture is also important, but is more limited to the domestic and individual context, and finally it is much cheaper because it is not done at large scales like the Agriculture.
