Macrophages engulf foreign material and destroy them using lysozymes.
When presented with antigen by antigen presenting cells, Helper –T cells produce
cytokines that activate B cells and triggers the adaptive immune response. T-helper cells determine the specificity of the adaptive response to an antigen. Cytotoxic-T-cells
destroys infected cells that have displayed an antigen on the MHC I surface receptors.
Suppressor T cells enable negative feedback by downregulating
immunity in cases when a foreign antigen
is eliminated. It also prevents autoimmunity.
Plasma cells are repsosncible for the production of antibodies in the humoral
immune response. Memory B and T cells ensure the immunity can remember an
infectious agent and therefore can launch a faster response in case of re-infection.
Answer:
<u>Starch</u> is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.
<u>Cellulose </u>is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.
<u>Glycogen</u> is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.
Explanation:
All of these sugars are polysaccaride sugars containing large number of glucose subunits.
Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.
Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.
Cellulose is the storage form of glucose in plants and leaves.
Answer:
B
Explanation:
According to Mendel, an organism receives two forms of a gene from each parent. This form received by each parent is called an ALLELE. An allele is the variant form of a gene for a particular trait.
For a diploid organism, two copies of genes (alleles) are acquired by an organism. The combination of these alleles from each parent determines the genotype for that gene.
In Mendel's experiments, he discovered that one allele can mask the expression of another for a trait. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. The combination of these alleles, whether two dominant or two recessive called HOMOZYGOUS or one dominant and one recessive called HETEROZYGOUS, determines the phenotype of the organism for that gene.
N.B: There are exceptions to this pattern of inheritance.
Answer:
C .Exocytosis is the process by which a large amount of molecules are released.
If you're talking about something that lives off of eating others to survive, this would be considered a heterotroph
If you're instead asking for what hunts others as prey, then you'd consider this a predator
<em>If this is a multiple choice question, try looking for one of those two as the answer.</em>
