This organelle modifies and labels proteins so they will be working properly and arrive at the correct destinations? so whats the answer?

Answers

Answer:

[tex]\boxed {\tt Golgi \ apparatus}[/tex]

Explanation:

After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.

In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.

So, the correct answer is Golgi apparatus.

Golgi apparatus

The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

I would say the answer is c or d

Answer:

D all of above

Explanation:

Polypeptides are chains of amino acids. They can coil/fold into different shapes. Some 'R'-groups are either hydrophobic, hydrophilic, or neutral in their charge. Suppose you have a very long polypeptide, where a part of the chain is hydrophobic and another part is hydrophilic. I go ahead and drop this long polypeptide in water and it coils up. How do you think it would coil? Why? What can you infer about the proteins in our bodies regarding this situation

Answers

Answer:

The hydrophilic part of the polypeptide chain would be oriented towards the surrounding water while the hydrophobic portion would be arranged away from the water and would make the hydrophobic interior resulting in coiling of the polypeptide chain. The body proteins assume the shapes to organize their hydrophobic parts away from the watery fluid.

Explanation:

Amino acids are the monomers of proteins. Each amino acid, present in proteins, has a central carbon atom. Four functional groups are attached to the central carbon atom of amino acid. These are the carboxyl group (COOH), amino group, a hydrogen atom (H) and a side chain (called R group). Amino acids differ from each other for the side chain present in them. Based on the nature of the side chain, amino acids are hydrophobic or hydrophilic or neutral. Sidechains of some amino acids are charged and have positive or negative charges on them.

The extracellular fluid of the body is a watery medium. Blood also has liquid plasma that is 99% water. The intracellular fluid, called cytosol, is also a water-based liquid.  

The hydrophilic side chains of the amino acids interact with the watery surroundings. They can make hydrogen bonds with the water. The charged hydrophilic R groups make electrostatic interactions with the surrounding medium. The hydrophobic R groups of the amino acids tend to arrange themselves away from the watery medium. This makes the part of the polypeptide chains with hydrophobic amino acids to fold so that these R groups are oriented away from the water.

Similarly, when a long polypeptide chain is dropped in the water, the hydrophobic R groups are arranged away from the water while the hydrophilic ones are arranged towards the surface of the chain facing the water. It is done to adopt a stable shape where maximum attraction forces are established.

Why did the narrator use the phrase "fit together like puzzle pieces" to describe how the cells of a developing human
embryo form a human face?

Answers

Answer:

The narrator uses that phrase because the pieces of the skin and face feathers have to come together as one to create a human head so they would be fitting together like puzzle pieces.

Explanation:

Answer:

The human face doesn’t form all at once. It requires many divisions of cells. As the cells divide, they eventually piece together to form a human face.

summarize the importance of stem cells

Answers

Answer:

Stem cells can become almost any cell in the human body.

Explanation:

This is important because in embryonic development, the body uses stem cells to form each individual part. For example, a single stem cell could become a heart cell, or brain cell, or a blood cell, or more. This is also important for possible treatments. In order to heal damaged or diseased bone tissue, blood stem cells can be taken out of the same person and used to fix the tissue. This allows for a lower rejection rate sense the cells used to fix the tissue were already part of the person's body.
