The answer is T-cells.

T-cells (T-lymphocytes) have a central place in cell-mediated immunity. On the surface of T-cells, T-cell receptor is present. When T-cell binds to the antigen via antigen receptor, the recognition occurs. Therefore, T cells act as a bridge between the cellular and humoral (antigen) response.

Which of the following attributes is common to both prokaryotic cells and eukaryotic cells?
yarga [219]

Answer:

b. the use of DNA as the information storage molecule

Explanation:

Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.

RSB [31]

Answer:

Here the fucose is linked to galactose by alpha1,2 glycosidic linkage.

Explanation:

Fucose is a deoxy sugar consist of 6 carbon atoms which means fucose is a hexose sugar.

   Fucose does not contain -OH group at C6 carbon that"s why it is termed as deoxy sugar.

     Fucose can link to both Nactylglucosame by alpha-1,6 glycosidic linkage and to galactose by alpha-1, glycosidic linkage  generates the H antigen.

   As donor is blood type B that means fucose is linked to galactoseof H antigen by alpha 1,2glycisidic linkage.

Fantom [35]

Answer:

b. False

Explanation:

All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). These intermediary products are produced at the glycolysis and citric acid cycle stage.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Hence, during respiration, most ATP is formed as a direct result of the net movement of protons down a concentration gradient but not potassium against a concentration gradient potassium.
