Which type of stem cell gives rise to red and whiteblood cells?a. endothelialb. epithelialc. hematopoieticd. mesenchymal

Bone marrow is a soft, spongy, connective tissue found inside bones. Bone marrow contains stem cells, which can generate new blood cells and, therefore, can treat many diseases of the blood. In the past, extracting bone marrow from a donor required anesthesia and a long, large needle. The process often discouraged people from signing up to be donors. A process called apheresis has made the process much less painful and invasive. In apheresis, the donor's blood passes through a sterile line into the machine. Once the blood is inside the machine, the bone marrow stem cells are extracted, and the remaining blood is returned to the donor. Donors typically only experience minor discomfort from the needles used and the loss of electrolytes. Describe how you think this advance in biotechnology will affect individuals and society. Be sure to include any potential medical or ethical issues that could arise from this new practice.

Epithelial tissue is an important part of the body as a covering of surfaces and as a lining of the internal hollow organs.  Discuss how histologists can use visualization of epithelial tissue to help with diagnosis of diseases in different parts of the body.

explains how the three characteristics below affect the function of this cell, its system or / and the body as a whole. Make the connection between the structures and functions of the body. 1. Red blood cells that do not have a nucleus 2.The length and ramifications of neurons 3.the insulating layer of myelin around a neuron

Erythrocytes do not have a nucleus. In what two cellular processes can they not engage? a. apoptosis and synthesis of lipid b. protein synthesis and cell division c. digestion of unwanted protein and cell division d. formation of vesicles and protein synthesis

What type of cells can be differentiated into many different cell types, including different blood cell types?  A. Erythrocytes B. Unipotent stem cells C. Platelets D. Pluripotential stem cells

One of the main functions of connective tissue is to integrate organs and organ systems in the body. Discuss how blood fulfills this role. answer quickly?

An individual is running to catch their ride share vehicle when they trip and fall with their hands outstretched. The individual looks up and notices an abrasion from the fall on the palms of their hands but there is no blood. What is the reason for the lack of bleeding?   A. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 5 layers on the palm to reach the vascularized (having blood vessels) basement membrane.   B. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 3 layers on the palm of the hand to reach the vascularized (having blood vessels) basement membrane.   C. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 4 layers on the palm to reach the vascularized (having blood vessels) basement membrane.   D. The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 6 layers on…
