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.
how does lipases contribute to homeostasis
Answer:
The presence of the cholesterol and short lipid tails keeps the cell membrane fluid, allowing the passage of necessary materials across its layer. This one major mechanism helps the cell with the maintenance of homeostasis.

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.

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.
The tails of the cell membrane are ____________ while the phosphate heads are ___________.
Hydrophilic, Hydrophobic
Hydrophobic, Hydrophilic
Flexible, Hydrophobic
Water Loving, Flexible
Explanation:
The tails of the cell membrane are __hydrophobic__ while the phosphate heads are __hydrophilic__.
I hope the following image helps to further explain the answer.
The tails of the cell membrane are hydrophobic while the phosphate heads are hydrophilic. The correct option is B.
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.

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.

Why does water have a strong surface tension and why is this important?
The stronger the cohesive force, the stronger the surface tension. The water molecule has two hydrogen atoms bond to an oxygen atom through covalent bonding. ... Formed bonds are called hydrogen bonds which lead to strong cohesive forces between the water molecules and high surface tension of water.
Why is it important?The surface tension of water provides the necessary wall tension for the formation of bubbles with water. The tendency to minimize that wall tension pulls the bubbles into spherical shapes. Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets.

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.

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.
