Hello. This question is incomplete. The complete question is:

"Which of the following describe a stem cell? Check all that apply. a cell that is able to develop into a variety of specialized cells a cell that is able to self-renew from differentiated cells a specialized cell that results in differentiation a specialized cell that results in self-renewal a cell that divides by meiosis to produce new cells "

Answer:

a cell that is able to develop into a variety of specialized cells
a specialized cell that results in differentiation

Explanation:

Stem cells are very special cells. They appear in the human being, still in the embryonic phase, before birth. After birth, some organs still hold within themselves a small portion of stem cells, which are responsible for the constant renewal of this particular organ. These cells have some distinct characteristics:

they can reproduce themselves by duplicating themselves, generating two cells with equal characteristics; furthermore it is a cell that is capable of transforming itself into a variety of specialized cells
they can differentiate, that is, transform themselves into several other cells of their respective tissues and organs.

An example is the hematopoietic stem cell, which in adults is located in the red bone marrow. In the bone marrow, it is responsible for the generation of all blood.

This is the cell that is effectively replaced when a bone marrow transplant is performed.

Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Sele

Virty [35]

Answer:

B. identifying the regions of human DNA that are transcribed into RNA

C. identifying the regions of human DNA that bind to proteins

D. analyzing the regions of human DNA that vary among individuals

Explanation:

The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.

GarryVolchara [31]

Answer:

1.)negatively charged protein

2.)positive anode

3.) shock

4.) ?

5.)decreased synthesis by the hepatocytes and water and sodium retention

Explanation:

1.Albumin is a negatively charged protein and its loss from the serum results in the retention of other negatively charged ions such as chloride and bicarbonate. As bicarbonate and chloride anions are used to calculate the anion gap, there is a subsequent decrease in the gap

2.At physiologic pH, most proteins are negatively charged, with albumin having a stronger negative charge and migrating further towards the positive anode, whereas immunoglobulins have the weakest negative charge and are closer to the negatively charged cathode.

3.?

4.?

5.Human serum albumin and liver cirrhosis

Patients with advanced cirrhosis almost always have hypoalbuminemia caused both by decreased synthesis by the hepatocytes and water and sodium retention that dilutes the

content of albumin in the extracellular space
