The structure of a Neuron: ___________ contains nucleus and organelles; _________ receives nerve impulses and conducts it towards cell body whereas _________ conducts nerve impulses away from the body.
Answer:
The structure of a Neuron: Soma/cell body contains nucleus and organelles; dendrites receives nerve impulses and conducts it towards cell body whereas axon conducts nerve impulses away from the body.
Explanation:
A neuron is the structural and functional unit of the nervous system. A neuron has three main structural components namely, soma, one axon, and many dendrites.
Soma is the metabolic center of the neuron and does not participate in conduction of nerve impulse. Many small extensions arise from the soma and are called dendrites. The function of dendrites is to carry the nerve impulse from axon terminals of the presynaptic neuron towards soma.
One large extension of soma is axon that carries the nerve impulse from soma to the axon terminals.

Why is the action of phagocytes considered a nonspecific response?
Answer:
Since phagocytes are effective against any type of infectious/toxic agent.
Explanation:
Phagocytes are the cells of the immune system that are involved in the non-specific immune response. These cells serve to engulf and kill any pathogenic or infectious microbe that has entered the body. Since phagocytes do not require the presence of specific antigens or pathogens to mount the immune response, their action is "non-specific response".
Answer:
D. It is not a response to a specific type of pathogen.

48) Capillaries lack smooth muscle and elastic or fibrous tissue reinforcement. Instead, theirwalls consist of ________, supported on a cellular matrix called ________
There’s no fill in words ?
Capillaries are formed from a single layer of endothelial cells, supported by a basement membrane. This structure allows them to be flexible, yet strong, and permeable to materials passing through them.
Explanation:Capillaries, unlike other types of blood vessels, lack smooth muscle and elastic or fibrous tissue reinforcement. Instead, their walls are composed of endothelial cells, which are supported on a cellular matrix known as the basement membrane or basal lamina.
In a large capillary, several endothelial cells may line the lumen, while in a small capillary there may be only a single cell layer that wraps around to contact itself. The basement membrane, which binds the endothelium to the connective tissue, provides strength while maintaining flexibility. It is permeable, allowing materials to pass through it.

a. Activation of an integrin receptor
b. Activation of a g-protein
c. Activation of an enzyme linked receptor
d. Increase in [Ca++]i
e. Increase in [Na+]i
Answer:
(d). Increase in [Ca++]i
Explanation:
Peptide hormones are hormones, synthesized by polymerization of amino acids that generally bind with receptors present on membrane of target cells. These hormones are produced in ER (endoplasmic reticulum) and are packed into secretory vesicles in Golgi for export.
These peptide hormone storing vesicles move to membrane of target cell and release their content due to increase in intracellular calcium (Ca++) ions concentration.
Thus, the correct answer is option (d).
Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type and what blood can she receive in order to save her life?
Answer:
Mrs Jones Blood type= B type.
Safe transfusion from: B and O blood type.
Explanation:
In the given example, the anti-B antibodies are present in the donor plasma. Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".
Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.
She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.

If a transgene is inserted into an animal embryo
only the non-reproductive cells should contain the transgene DNA.
the animal should become sterile as an adult.
every cell should contain the transgene DNA.
the transgene protein will be expressed in all cells.
only the sperm and egg cells should contain the transgene DNA.
Answer:
Every cell should contain the transgene DNA.
Explanation:
The embryo is the very early stages of growth and development of an organism. An embryo develops from a zygote and contains about 16 cells. Inserting transgenes in these cells, therefore, will ensure that all the cells that divide from the embryo by mitosis have the transgene. The whole organism will, therefore, bear the transgene including its gametes. This foreign gene will, therefore, be inherited by the offspring of the organism.

The frequency of a deleterious recessive disease in a large, randomly-mating population is 1 in 1000. Calculate the probability of an individual being a carrier for this recessive disease?
a) 0.74
b) 0.06
c) 0.03
d) 0.001
e) All individuals will be homozygous
Answer:
The frequency of carriers for the recessive disease is 0.062.
Explanation:
The frequency of recessive allele in the generation is 1 in 1000.
Let the frequency be q²=1/1000.
q=√1/1000.
q=0.032.
Let p be the frequency of dominant allele
p+q=1 ( According to hardy weinberg equillibrium)
p=1-q
p= 1-0.032
p=0.968.
The frequency of carriers for the recessive disease = 2×p×q
=2×0.032×0.968
=0.062.
