Answer:

Explanation:

The main goal of metabolism is for the ultimate release of energy. Energy is simply a function of the ability to do work. In this context, we consider energy in one of it forms, chemical energy.

The chemical energy obtained through digestion of food mostly in the form of glucose is the fuel for almost all of life's processes. This chemical form of energy serves as the power house for our functioning.

Energy is required by the brain to power it and carry out its function. Without energy being supplied to the brain, there won't be a living being.

Energy is needed for locomotion and other life activities. The muscles, bones and other appendages gets their coordination power from the energy released during metabolic processes.

It can be said that all life activities revolves round how organisms obtains and utilize energy.

Nutrients are the nourishment we derive from feeding. The nutrients helps to build our body parts e.g proteins. Energy are derieved from carbohydrates. Fats and oil are also energy sources and they help life functions. Vitamins and minerals supplies needed materials to make everyday life activities successful.

Non example of mitochondrion

Yuliya22 [10]

The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.

In the marine mollusk, Aplysia, serotonin binds to a G-protein-coupled receptor and activates a Gs subunit. The resulting activa

dem82 [27]

The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.

Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses. Without this activity, the transmission of signals would be impossible.

If you know that a population is 75% the dominant phenotype and 25% is the recessive phenotype, can you determine approximately

Andreyy89

If dominant allele = p, and recessive allele = q,
and p+q = 1, then:
${(p + q)}^{2} = {p}^{2} + 2pq + {q}^{2} \\ where \: {p}^{2} \: is \: homozygous \: domin \\ {q}^{2} \: is \: homozygous \: recessive \\ and \: 2pq = heterozygous$
So if 75% have the p, then p^2 = homozygous dominant
${p}^{2} = {(.75)}^{2} = .5625$
And if the other 25% have the q, the q^2 = homozygous recessive
${q}^{2} = {(.25)}^{2} = .0625$
Now those remaining MUST be the heterozygous, thus 2pq are those:
2pq = 2(.75)(.25) = .375

Therefore homozygous dominant are 56.3% and heterozygous are 37.5%
