In humans, albinism is caused by loss of function mutations in genes involved in the synthesis of melanin, the dark pigment in s

kin. Only people homozygous for loss-of-function allege (genotype aa) have the albino phenotype. In Americans of northern European ancestry., albino individuals are present at a frequency of about 1 in 10,000 (or 0.0001). Assuming that genotypes are in Hardy-Weinberg equilibrium, what is the predicted frequency of Caucasians in the United States who carry a single allele for albinism

Difference between cytoplasm ans cell sap?
Ludmilka [50]
Cell saps are the liquid inside of a plant cell's large central vacuole, which acts as support in order for it to function. They're made up of amino acids, glucose, salts and water and plays an important role in osmosis.
Cytoplasms, on the other hand, are a jelly-like substance between the cell membrane and nuclear envelope within a eukaryotic cell. They're mostly made up of water and salt, and aid in growth and metabolism in a cell.

Which synapse(s) are specifically responsible for the sensitization of the withdrawal response?
qaws [65]

The correct option is (e) sensory neuron to motor neuron, responsible for the sensitization of the withdrawal response.

The central nervous system receives the excitation from a sensory neuron that has been stimulated by its nociceptors. Notably, these fibres deliver excitement to the sensory neuron's cell body, which is located in the spinal cord's dorsal root ganglia. The sensory neuron in the dorsal root ganglion transmits excitatory postsynaptic potentials (EPSPs) to motor neurons and interneurons after receiving the action potential from these fibres.

By releasing neurotransmitters into the central nervous system, the sensory neuron does this. Excited somatic motor neurons contract and depolarize the targeted muscles to complete the withdrawal reflex. The motor neuron, which leaves the spinal cord and enters the peripheral nervous system, is where this depolarization travels.

Therefore, sensory neuron to motor neuron is responsible for the sensitization of the withdrawal response.

What is responsible for the yellow-orange coloration of leaves in the fall?
mixer [17]

The correct answer is - C) carotenoids.

The majority of the trees from the mid-latitude forests tend to shade their leaves in the autumn. This process occurs because of the seasonal changes in the climate, where the trees tend to be almost not-active during the winter, so in order to preserve as much energy and nutrients as possible they get read off their leaves.

It is not a sudden process, but it takes some time, where the leaves from the initial green color start to change to yellowish, than towards orange, reddish, or brownish before they fall.

The reason why this coloration appears in the leaves when the tree starts to process of shading them off are carotenoids. The carotenoids found in the leaves, the lutein and the beta-caroten, thorugh the xantophills and the flavonoids give a yellowish color to the leaves, thus we get the beautiful autumn colors and landscapes.
