Sebaceous glands are glands found in the skin of mammals, including humans.

They are flask-shaped and typically have short ducts that open into hair follicles or directly onto the skin. These glands produce an oily substance called sebum, which helps to lubricate and protect the skin and hair. Overproduction of sebum can lead to conditions such as acne, while underproduction can cause dry skin. The activity of the sebaceous glands is regulated by hormones, particularly androgens, which increase their activity during puberty. The glands also play a role in the development of skin conditions such as seborrheic dermatitis and rosacea.

Answer:

The correct option is;

7:32 AM

Explanation:

The information given are;

The time at 45 degrees W and 72 degrees N = 9:32 AM

The variation of time with lines of longitude  is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west  of the initial location

Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted

The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM

The latitude of a place left out in the calculation of the relative time of a place.

A compound must be asymmetric to possess optical activity. Optical activity refers to the ability of a substance to rotate the plane of polarized light.

This phenomenon occurs because the substance has a chiral or asymmetric molecular structure, which means that it cannot be superimposed on its mirror image. As a result, the molecule interacts differently with polarized light depending on its orientation, causing the rotation of the plane of polarization.

Polarization is a property of waves that describes the orientation of the oscillations in the wave. It refers to the direction of the electric field vector in an electromagnetic wave, which can be oriented in different directions with respect to the direction of wave propagation.

The peripheral nervous system (PNS) is the portion of the nervous system that exists outside of the central nervous system (CNS). It is composed of all the nerves and ganglia that connect the CNS to the rest of the body.

This system is responsible for sending sensory information to the CNS, such as pain, temperature, and pressure, and for sending motor commands from the CNS to the muscles and glands.

The PNS is also involved in controlling reflexes, which are involuntary reactions to stimuli. It is divided into the somatic nervous system, which is responsible for voluntary control of skeletal muscles, and the autonomic nervous system, which is responsible for involuntary control of organs and glands.

The sympathetic nervous system and the parasympathetic nervous system are subsets of the autonomic nervous system. The enteric nervous system, which controls the digestive system, is also a part of the PNS.

A cell that is 3% salt is placed in a container of pure water.

Answer:

If there is 5% salt on the outside of the cell and 20% salt on the inside of the cell, the environment would be considered osmotically imbalanced or osmotically stressed.

Explanation:

In general, cells are surrounded by a membrane that separates the inside of the cell from the external environment. This membrane is selectively permeable, meaning that it allows certain substances to pass through while blocking others. In the case of a cell in an osmotically imbalanced environment, the concentration of solutes (such as salt) is different inside and outside the cell, which can cause water to flow in or out of the cell in an attempt to balance the concentration of solutes on both sides of the membrane.

If the concentration of solutes is higher inside the cell than outside (as in the case you described, with 20% salt inside and 5% salt outside), this can lead to an excess of water inside the cell, which can cause the cell to swell and potentially rupture. On the other hand, if the concentration of solutes is higher outside the cell than inside, this can cause water to flow out of the cell, leading to dehydration and potentially damaging the cell.

Osmotic stress can have a range of effects on cells, depending on the severity and duration of the imbalance. In some cases, cells can adapt and survive in an osmotically imbalanced environment, but in others, the stress can be lethal.

Answer: The physical state of the material depends on the intermolecular interaction between hydrogen molecules....and here this is only a fairly weak dispersion force, which is reasonable because the molecule is certainly non-polar, and is not many electron. ...

Explanation: Several of the nonmetals are gases in their elemental form. Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).

When the ribosome reaches the end of the mRNA strand during the process of translation, the polypeptide chain has been fully synthesized. The ribosome releases the polypeptide from the mRNA and dissociates from the mRNA molecule.

In eukaryotic cells, the polypeptide may undergo further modifications and folding to attain its functional conformation. It may be targeted to specific cellular compartments, such as the endoplasmic reticulum (ER), for further processing or secretion.

The direction of the ribosome/mRNA complex to the ER receptor is facilitated by a signal sequence present in the growing polypeptide chain. This signal sequence is recognized by a signal recognition particle (SRP), which is a complex of proteins and RNA. The SRP binds to the signal sequence and guides the ribosome/mRNA complex to the ER membrane, where it interacts with the ER receptor. This process is known as co-translational translocation and ensures that proteins destined for the ER or secretory pathway are properly targeted and inserted into the ER membrane.

If you scratch your eye, you can damage the cornea, which is the clear outer layer that covers the iris and pupil.

The cornea is a delicate and extremely sensitive part of the eye that serves a vital role in focusing light onto the retina, allowing us to see with clarity.

It's made up of several layers of cells and lacks blood vessels, meaning it relies solely on the surrounding tissues for essential oxygen and nutrients.

Scratching the cornea can disrupt its smooth surface and cause abrasions or scratches, leading to intense pain, extreme sensitivity to light, blurry vision, and a surge in tear production.

And it only gets worse from there. In severe cases, a corneal abrasion can become infected, resulting in corneal ulcers that can potentially threaten your vision.
