7 0
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell. 

The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.
lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which  leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase)   that  metabolize activities of  cholinergic   neurotransmitters  e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites  transmits action potential to the  neuromuscular junction is called presynaptic neuron. While  neuron that  transmit action potential away from the neuronal synaptic junction, or from the neuromuscular  junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called  post synaptic  neuron.

The more  negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of  activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to  continuous   excitatory activities  of cholinergic neurotransmitters   on  the receptors at the postsynaptic neuron, and the more  action potential

Imagine a population of rabbits with fur color that ranges from black to white. If this population were put in an area that has
Molodets [167]

The correct answer is option (C) Gray rabbits would be eliminated by predators.

Camouflage is an adaptation by organisms allowing them to blend with the environment. This helps them in surviving or escaping from their predators. It can be throught coloration or developing a particular pattern or mimicry.

The example given above is a type of camouflage through concealing coloration. Concealing coloration includes having a fixed camouflage and changing the camouflage depending on the environment. Grey rabbits cannot exhibit camouflage as the backgroud is dark rocks and light stones. As a result, these rabbits are clearly visible to the predators and get elimiated by them.
