Differentiate Humoral immunity vs cell mediated immunity
trapecia [35]

Answer:

Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.

The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.

Describe two examples of how an understanding of genetics is making new fields of health care(treatment or diagnosis)possible?
WARRIOR [948]

Answer:

Genetics is a branch of science that deals with the study of genes, their sequence, function, variation, and heredity.

Increasing understanding of genetics help in making new fields of health care, for example,  

  • Gene therapy helps in treating various genetic diseases such as cystic fibrosis et cetera.
  • Molecular genetics help in the development of more precise methods for diagnosis such as ELISA.
  • Pedigree analysis and karyotypes help in early detection of possible hereditary diseases.
  • DNA fingerprinting helps in detecting criminal suspects, paternity test, identification of dead organism et cetera.

I need help on this Asap. i also need an explanation to go with the answer.
Anna35 [415]

Answer:

For question 20. I believe the answer is C. There would be more iguanas with webbed feet.

Explanation:

It states the iguanas have adapted to different habitats on the island. The iguanas that have webbed feet will be better at getting food in water, but slower on land. So if the land starts to disappear and turns into more water, the iguanas with webbed feet will have a higher chance of survival. Meaning the iguanas with out webbed feet will die out as a population.

An action potential triggers the release of synaptic vesicles into the synaptic cleft by _____ channels, allowing _____ ions to
noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.
