Explanation:
To be precise, homeostasis is a process/phenomenon not a system. Homeostasis is actually the process of maintaining a stable internal environment despite changes in the external environment. There are mechanisms in organisms that regulate pH and this regulation is an example of homeostasis.
integral proteins are important to maintain the strength of the cell membrane. true of false?
Answer:
false
Explanation:
Integral proteins are one type of membrane protein. They are constantly associated with the membrane, carrying out many different functions but they do not maintain the strength of the cell membrane. The sentence is False.
-----------------------------------
Plasmatic membranes are composed of lipids and proteins.
Among the proteins, we can find integral proteins and peripheric proteins.
Integral proteins are permanently associated with the membrane.
They accomplish many different functions such as substances transport, cellular receptors, cellular adhesion, among others.
According to how they are incrusted in the lipidic bilayer, integral proteins might be,
Transmembrane proteins ⇒ span the entire membrane⇒ present in every membrane cells
Monotypic integral proteins ⇒ attached to only one of the lipidic layersIntegral proteins provide structure to the plasmatic membrane, but they do not maintain its strength.

Disease or disorder that affects the nervous systems
Answer:
There are many diseases/disorders that affect the nervous system, but here are a few:
Alzheimer's disease
Parkinson's disease
Epilepsy
Stroke
Explanation:
Alzheimer's disease: Alzheimer's disease is a progressive disease (gets worse and worse overtime) that destroys your memory. When a person has Alzheimer's disease, their neurons (nerve cells) get damaged and eventually die all throughout the brain. Some problems people with this disease can experience are: getting lost easily, personality/behavior changes, memory loss (obviously), and need help with self-care and daily things.
Parkinson's disease: Parkinson's disease is a progressive disorder that affects one's movement. Because the nerve cells are damaged, the dopamine (type of neurotransmitter) levels decrease. Since dopamine can control your body movement, it makes it hard to balance, and you're usually stiff. It usually begins with a tremor in your hand.
Epilepsy: Epilepsy is a neurological disorder where neuron activity in the brain gets disturbed, resulting in a seizure. Epilepsy is usually genetic or gained through a trauma or stroke (brain injuries). During these seizures, people often lose consciousness. Most epileptic people are sensitive to lights (flashing and flickering especially).
Stroke: A stroke occurs when your blood supply to your brain is interrupted/stopped. This is a SERIOUS emergency. Cells can die from lack of blood and the resulting lack of oxygen. Most warning signs of a stroke include: numbness + weakness, trouble speaking, loss of balance, and dizziness.

Which coast of North America would you expect you to have a cooler overall climate
Answer:
east coast
Explanation:
During the winter, land is much colder than the oceans. When the westerly winds blow over it, the air cools substantially. By the time it reaches the East Coast, the moist air is cold enough to convert into snow. Thus, the East Coast experiences extreme cold weather during the winter.

A human has 46 chromosomes in each body cell. How many chromosomes would be found in its daughter cells after mitosis
Answer:
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.

Enzymes are (d)_________- each one controls only one type of reaction. They are (e)_________by high temperatures and by extremes of ph.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Explanation:
Maybe this will help?
Enzymes are proteins that speed up the biochemical reactions in living organisms, and they are biological catalysts. Enzymes are substance-specific, each one controls only one type of reaction. They are denatured by high temperatures and by extremes of ph.
What are enzymes?Enzymes are biocatalysts made up of proteins, that increase the speed of the reaction.
Enzymes do not involve in the reaction and in the end of the reaction they separate from the reaction their substance is specific they are specific to reactions whose speed is increased by these enzymes.
In high temperatures and pH their structure changes as they are protein and with extreme where they also get the nature

to prevent acid from seeping in the stomach, the stomach cells join one another via
The stomach and the cells that comprise it have a three-part protection system to protect from the acid contained in the stomach, comprised mostly of compact cell unions.
The stomach is one of the main digestive tract organs. Its job is to break down the food we ingest and pass it along to the rest of the digestive tract. To perform this action, the stomach secrets hydrochloric acid. However, the stomach itself is not damaged by this acid due to a three-part protective system comprised of:
Tight epithelial cell liningMucose BarrierBicarbonate secretionThe cells present in the epithelial lining of the stomach join one another via compact cell unions to form a closed barrier which is then covered by a thick Mucose barrier. This along with the secretion of bicarbonate which works to break up the acids present in the stomach and ingested, form a sealed barrier that protects the stomach from harm.

when does an electron emit energy in the form of a photon?
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
how does your body acquire the oxygen the cells in your body need to function?
Answer:
You take in oxygen and it goes to your lungs. It spreads through your body, going through your bloodstream, and going to your heart. The excess oxygen turns into carbon dioxide leaves through your mouth. When it leaves, the plants take the carbon dioxide and turn it back into oxygen, and repeating this process.
(I'm pretty sure this is the answer. Hope it helps:)
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
What are the functions of hemoglobin?Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs.
Hemoglobin, abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the respiratory organs to the rest of the body.
Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.

What is the end result of crossing-over during the first stage of meiosis?
-the paternal DNA only is copied onto the chromatids
-the chromatids are identical to each other
-the chromatids contain the maternal DNA only
-the chromatids become non-sister (non-identical) chromatids
Answer:
The chromatids contain the maternal DNA only.
Explanation:
They must contain half the original number of chromosomes. It must contain only one chromosome in place of each homologous pair of chromosomes, so it is endowed with either the maternal or the paternal copy of each gene but not both.

What is the structure of cell membrane?The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure. These compartments are the inside and outside of the cell in the case of the plasma membrane.
The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The membrane of the cell is composed of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
The heads (phosphate) are polar, whereas the tails (lipid) are non-polar. The heads, which form the outer as well as inner linings, seem to be "hydrophilic" (love water), whereas the tails, which face the cell membrane's interior, are "hydrophobic" (water fearing).
Thus, the correct option is B.
