Genrish500 [490]3 years ago
8 0
The most accurate classification of the common forms of coronary artery disease and hypertension is that they are complex disorders which result from gene-environment interactions. For example, almost 60% of CAD cases are found in South East Asia, that too when their population if just 20% of the total world's population. This is due to the environmental interactions with the genetic disposition of the people of this region.

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

Explain how the action of a peptide hormone is similar to the action of the neurotransmitter norepinephrine
-Dominant- [34]
Neither the peptide hormones or the metabotropic neurotransmitters such as the catecholamines, can enter their target cells. They bind to surface receptors, which then activate second-messenger systems in the cell. Peptides hormones are the hormones that consist of amino acids; they can be among the intracellular signalling peptides and proteins, and can include insect hormones, gastrointestinal hormones and thyroid hormones, but their actions are not limited to individual cells and they can act systemically.

At one gene locus in humans there are 2 alleles: one for curly hair and another for straight hair. Neither allele is dominant, a
Dovator [93]

Answer:

25%

Explanation:

<u>Genotypes and phenotypes:</u>

  • SS = straight hair
  • CC= curly hair
  • SC = wavy hair
  • AA or A0= type A blood
  • BB or B0= type B blood
  • AB = type AB blood
  • 00 = type 0 blood

A man with straight hair and A blood has the genotype SS AA or SS A0.

A woman with wavy hair and B blood has the genotype SC BB or SC B0.

Their first child has straight hair and O blood: SS 00

Because the child has type 0 blood, both parents must have a 0 allele, so their genotypes are SS A0 and SC B0.

<u>If their second child is a boy with straight hair, what is the probability that he has A blood?</u>

The hair and blood type genes are independent, so the hair phenotype of the child is irrelevant to determine the probability of him having A blood.

The parental cross for blood type is A0 x B0.

If you do a Punnett Square, you'll get the following offspring:

25% AB, 25% B0, 25% A0 and 25% 00.

The answer is the child has a probability of 25% of having A blood.
