Opioid drugs. They disrupt the natural production of norepinephrine and act as central nervous system depressants. Opioids block pain sensations, induce drowsiness, reduce body temperature, and slow heart rate, blood pressure, and respiration functions.

In photosynthesis, how does the movement of electrons along the electron transport chain affect hydrogen ions (h+)? how does thi
lukranit [14]
As electrons move along the chain, hydrogen ion are pumped from the stroma of the chloroplast into thylakoid lumen. these leads to creation of proton gradient in thylakoid lumen with the potential energy that will be used to synthesize ATP by enzyme ATPase in the process referred to as rotational catalysis. both chloroplast and mitochondria use electron transport chain to pump protons across the membrane and both enzyme ATPase to produce ATP using proton gradient created in the process of transport of hydrogen ions. the main existing between the electron transport chains of chloroplast and mitochondria is the initial source of energy. chloroplasts obtain their energy from sunlight whereas mitochondria obtain theirs from organic molecules.

A sexually reproducing animal has two unlinked genes (on separate chromosomes), one for head shape (H) and one for tail length (
Verizon [17]

Answer:

a) HT

Explanation:

This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.

According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.

Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.

Therefore, HT is the genotype possible in a gamete of parent: HhTt.
