Answer:
(08) and (32)
Explanation:
To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.
The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.
Answer:
C
Explanation:
The major histocompatibility complex (MHC) is a group of genes whose function is to codify proteins that participate in the immune response, helping the system to <u>recognize foreign substances to develop an immune response</u>.
<u>Histocompatibility or compatibility of tissue </u>is given by self-identifications molecules (antigens) located on the surface of cells, membrane, these molecules are almost <u>unique to each person</u>, letting the body to distinguish self from non-self.
Answer: False.
Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
The correct answer is biological anthropology, or physical anthropology.
It is centered around human beings only, with respect to their common or different features that they either share or don't share with their related non-human primates and other ancestors. It deals with human evolution, the study of their behavior, reproduction, etc.
Answer:
The correct answer is : * Membrane carbohydrates function primarily in cell-cell recognition.
Explanation:
The carbohydrates (poly or oligosaccharides) associated with the plasma membrane, are covalently bound to it (to proteins or lipids). They are found in the outer part of the plasma membrane forming the glycocalix. Its main functions are:
-Cell recognition
-Support to the membrane.
