a. You are startled when a friend pulls a practical joke and spooks you with a loud sound.

b. You move your arms and legs to take an evening walk.

c. Your stomach makes a gurgling sound as it digests your lunch.

d. Feeling a little stressed? You take a few breaths to calm down.

e. You are at the line, waiting for you race to start, and your heart begins to pound.

Answers

Answer 1

A startle reflex (a), digestion (c), breathing (d) and heart pumping (e) are responses of the ANS, while arm/leg movement (b) is a response of the SNS. They are major divisions of the PNS.

The peripheral nervous system (PNS) serves to connect the central nervous system to different organs, limbs, and skin.

The PNS can be divided into Somatic Nervous System (SNS) and Autonomic Nervous System (ANS).

The Somatic Nervous System is responsible for controlling the voluntary movements of the body.

The Somatic Nervous System is responsible for regulating the involuntary movements (reflexes) of the body.

Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.

Answers

Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.

Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.  

On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.  

Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.  

Hence, the correct statements are

what is the primary action of antidiuretic hormone?

Answers

Answer:

The primary action of the antidiuretic hormone is that it causes collecting ducts in the kidneys to reabsorb more water.

Explanation:

Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.

What is Anti-diuretic hormone (ADH)?

Human vasopressin is also called antidiuretic hormone, arginine vasopressin or argipressin. It is defined as the hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus that converts to AVP.

ADH is the hormone that helps constrict blood vessels and helps the kidneys control the amount of water and salt in the body which helps control blood pressure and the amount of urine. This reduces the amount of urine released and the nature of urine becomes hypertonic which is concentrated. Because of this type of action, vasopressin is known as an antidiuretic hormone.

Thus, Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.

When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.

Answers

Answer:

Different organelles make close contacts with each other via MCSs. These contact sites are generally thought to form via membrane proteins that act as tethers on the interacting organelles . Often these tethers are part of large multiprotein complexes.

The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus, which we will cover shortly.

There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.
