What does the graph tell you about the concentration of salt inside the cell?

Answers

Answer:

So,

Assuming that the plasma membrane is either semipermeable or fully permeable, either diffusion or osmosis will even out the concentration eventually.  Therefore, options A and B are eliminated.

The only options left both say that osmosis will take place.  We know that osmosis will always move the solvent from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell).  Thus, water will move into the cell through osmosis.  That is option C.

If the cell cannot get rid of the water quickly enough, the cell will explode by cytolysis.

1)What are some examples of specialized cells
and what do they do?
2) Why is the specialization of cells in organisms
significant and important for homeostasis?



























any spams or scams will be reported and given a low rating

Answers

Answer:
mast cells, melanocytes, nerve cells, cardiac muscle cells
Explanation:
There are lots of examples of specialized cells, but here are four.
Mast cells - release histamine and heparin, which are important in directing the inflammatory response. These cells direct the first line of defense in preventing infection
Melanocytes - release melanin, which is a brown pigment that gives skin and hair its color. This is an important process because melanin reflects UV light, which can damage DNA in skin cells
Nerve cells - specially designed to allow nerve impulses (called action potentials) to travel throughout the body. They use electrical signals to allow the whole body to communicate
Cardiac muscle cells - responsible for muscle contraction of the heart. They have specialized structures like intercalated discs that allow rapid communication between cells. This is important because every cell in the heart has to contract at the same time to allow blood to flow properly throughout the body.
The specialization of cells in organisms is important because it allows us to do many specialized functions. Non-specialized cells are pretty limited in what they are able to do, so they are small and inefficient. Specialized cells also help prevent disease, which is the opposite of homeostasis.

Which of the following emotions is the last to develop in an infant?
Select one:
a. pride
b. fear of strangers
c. anger
d. curiosity

Answers

A. Prided because they it’s not very common
Their develop shy and not interested in propel they don’t know and anger when they get something they don’t want is very common along with curiosity they are new and have so much to learn


So answer A Pride

Pride is the last emotion to develop in an infant. So the correct option is A.

When do emotions develop in an infant?

From the moment of birth, babies are able to convey their curiosity, pain, disgust, and enjoyment through their body language and facial expressions. Around 2 to 3 months old, babies start smiling spontaneously, and around 4 months old, they start laughing. Infants also display other emotions, such as anger, sadness, surprise, and fear, between the ages of 2 and 6 months. Babies start to show signs of stranger fear between the ages of 5 and 6 months.

They will express their displeasure openly when someone holds or plays with them since they do not enjoy it. They used to grin at everyone and let people hold them. Babies are nevertheless learning at this time how to recognize the sentiments of others as well as how to express their own. Infants can start recognizing the various emotional emotions of others at the age of 4 months. Babies don't start mimicking emotions and facial expressions until they are approximately 6 months old.

Babies generally treat their caretakers interchangeably at birth because they lack the ability to recognize individual differences. They do, however, start to develop a strong attachment or relationship with their primary caretakers as the months of their first-year pass and their perceptual and processing capacities advance.

Therefore, the correct option is A.
