Answer: Carbon is the most important element in organic compounds, which means that life on earth is possible thanks to this atom and its characteristics. Below you can see some of the ones I consider to be the most relevant

Explanation: Carbon atom has 6 protons and 6 neutrons in its nucleus, and that nucleus is surrounded by 6 electrons. Those electrons are distributed two in their first level (called s) and four in their second level (called p).

It is tetravalent, because it has 4 electrons orbiting its last energy level, which can be combined with other atoms, even with another carbon atom forming covalent bonds. , present in all the organic compounds.

Thanks to these electrons, it can form three hybridizations or types of junctions; single, double or triple. This is important for molecular geometry: the single bond determines the formation of a tetrahedron, with angles of 109.5 ° , the double bond determines the formation of a flat triangular structure, with 120 ° angles  and the triple bond determines the formation of a linear structure, with 180.

This are some of the most importan characteristics tha make Carbon a unique element.

two parents with normal phenotypes have a daughter who genetically inherited a disorder. Explain how this is possible.
sukhopar [10]

Answer:

              Phenotype is physical appearance of the individual while genotype is the genetic makeup of the individual.

Explanation:

                      Two parents having normal phenotype but effected individual is due to the parents may be Carrier for the particular deseis and the gene responsible for the desies may be in recessive form and the parents are not effected.  The gene is not present in dominant form and can not show its effect but the parents are not effected and the daughter may be affected by certain desiese.

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.

                   nucleotide                 wild-type                mutated

<u>                       location                 nucleotide              nucleotide      </u><u>           </u>

Patient 1            143                         TTC                         TGC

Patient 2           143                         TTC                         TCC

<u>Patient 3           147                          TTC                        TTG                         </u>

Compared to other receptors, what makes steroid hormone receptors unique?
Dafna11 [192]

Answer: b)Steroid hormone receptors are located within the cytoplasm of a cell.

Explanation: Steroid hormones are the element present in the body that provides management in inflammation, metabolism, illness resistant , improves immune function etc. They are obtained from the cholesterol. The particular receptors of the steroid hormone is located at the cytoplasm.

Other options are incorrect because steroid hormone binds the certain receptors only not neurotransmitters .It does not have domain of 20 trans-membrane and is bound to ligand for activation.Thus , the correct option is option(b).
