Answer:
Post-synaptic neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.
Explanation:
Postsynaptic neuron
:
These are the neurons that is present after the gap called synapse. These neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.
There are number of neurotransmitter. These includes
GABA ergic: This neurotransmitter is often inhibitory.
glutamatergic: This neurotransmitter is often excitatory.
Adrenergic: This neurotransmitter releases norepinephrine.
Cholinergic: This neurotransmitter activates vertebrate neuromuscular junction.
Answer:
Pia mater
Explanation:
Three meninges cover the brain and spinal cord. Pia mater refers to the deepest meninx of the brain. It is a thin delicate layer of connective tissue. It is a transparent connective tissue layer like that of cellophane. Being a transparent and thin tissue layer, it looks like a cellophane wrap adhered to the surface of the brain.
One consequence of CFCS pollution is increased rates of skin cancer in humans.
Cholofluorocarbons cause the breakdown of the ozone layer that protects the earth from the sun's ultraviolet radiation. Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are brojken up by ultraviolet radiation, releasing the chlorine that catalytically destroys ozone.
The provided question has marked options incorrectely the correct order as follows:
A) Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.
B) Measure the amount of post-translational processing that occurs in the putative DNA repair mutant plants.
C) Measure the somatic mutation rates for the putative DNA repair mutant plants.
D) Expose the putative DNA repair mutant plants to a deaminating agent and select those that have a decreased mutation rate.
E) Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.
Answer:
The correct answer is: A), C) and E)
Explanation:
The breeder wants to isolate the mutants in tomatoes that are defective in DNA repair, to identify such plants breeder should follow these methods as they will allow best to identifying the defective tomatoes-
Measure the somatic mutation rates for the putative DNA repair mutant plants.
Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.
Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants. This will allow the breeder to see and analyze the ability of DNA repair in tomatoes
Answer:
2
Explanation:
plants do have dna in the nucleus
