Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to

Natali [406]

Answer:

The correct answer is: do not enter into a plexus and directly connect to the structures they supply.

Explanation:

The anterior rami of the thoracic spinal nerves from T1 to T11 give birth to the intercostal nerves, which are part of the somatic nervous system.

The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, directly connecting to the structures they supply.

The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.

Explanation:

When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.
its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.

Conservationists establish that the minimal viable population of a population of tigers in an extensive geographical area is 16.

Sphinxa [80]

Conservationists establish that the minimal viable population of a population of tigers in an extensive geographical area is 16. Given that the current population of tigers is 10, which is lower than the established minimal viable population, the tigers will die out because they will be unable to sustain their population.

<h2>Peptidoglycan Cell Wall </h2>

Explanation:

A cell wall containing peptidoglycan and distinctive ribosomes
Bacterial cell dividers are made of peptidoglycan (additionally called murein), which is produced using polysaccharide chains cross-connected by irregular peptides containing D-amino acids
Gram-positive microscopic organisms have a thick cell divider containing numerous layers of peptidoglycan and teichoic acids
Ribosomes are small particles which is related proteins that capacity to synthesize proteins and comprising of RNA
Proteins are needed for many cellular capacities, for example, directing chemical procedures and repairing damage
Ribosomes can be discovered drifting inside the appended to the endoplasmic reticulum or cytoplasm
