The adrenal medulla is stimulated to release catecholamines during sympathetic autonomic nervous responses. True or False

forsale [732]

Answer:

True

Explanation:

Catecholamines refer to the hormones produced by the adrenal gland present on the upper side of the kidney. The catecholamine hormone includes the epinephrine, norepinephrine and the dopamine.

During stress conditions, the sympathetic division of the autonomic nervous system gets activated which leads to the release of the norepinephrine from the postganglionic neurons and the prolonged-release leads to the release of the adrenaline from the adrenal glands.

Thus, true is the correct answer.

What is systematics and why is it a less arbitrary and more natural approach to categorizing living organisms?

klio [65]

Systematics is the study of the units of biodiversity. Systematics differs from ecology in that the latter is concerned with the interactions of individuals (and therefore species) in a particular time.

GrogVix [38]

Explanation:

A. The differential induction of DNA transcription suggests the cells are destined to become different tissues.

Given the lack of RNA encoding, DNA transcription is not occurring. This may happen because the cells are destined to undergo different forms of differentiation- here, transcription would require the activation of different regions of the genetic code called transcripts.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
