mass and distance

Explanation:

OLga [1]3 years ago

Answer:

The masses of the objects and the distance between them

Explanation:

The formula for the force (F) of gravity is  

F = \dfrac{Gm_{1}m_{2}}{r^{2}}

where m₁ and m₂ are the masses of the two objects and r is the distance between them.

Thus, the force of gravity depends on the

  • Masses of the objects
  • Distance between them

Lions tend to prey on primary consumers like zebras and gazelles. if there were a sudden decline in a population of lions, which
KatRina [158]

There would be an increase in "Zebra" and "Gazelle" population. This is due to the fact that there wouldn't be as many lions to eat the zebras and gazelles, causing their repopulation to become more frequent.

An individual with Huntington disease has two normal parents. What are plausible explanations for this pattern of inheritance? C
Vitek1552 [10]

Answer and Explanation:

The Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.

The Huntington disease characterizes for being,

  • Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene.
  • Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.
  • Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.
  • Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.

There are just a few cases all around the world (3% approximately) in which the disease is expressed with no family history. The progenitors are not affected by the mutation. These cases are very rare and are called <u>"de-novo" mutations.</u> A new mutation is spontaneously produced and it is not inherited from any of the parentals. It consists of an increase in the number of CAG repetitions. In a normal person, the number of CAG repetitions is less than 35. When there are 40 or more repetitions it occurs the disease. But when there are between 35 and 39 repetitions, the penetrance of the disease is incomplete. This is a "gray zone". Those alleles that fall in the gray zone are unstable and might produce the HD. Individuals with these unstable alleles have a tendency to increase the number of repetitions from generation to generation until the number reaches 40 repetitions and the person expresses the disease. This <u>usually occurs in the paternal germinal line</u>, as it is particularly unstable in sperm and probably meiosis greatly affects their instability, causing an increase in the number of CAG repeats.

where the carbon atoms of acetyl coa end up and where the energy that was stored in acetyl coa ends up. krebs cycle
ruslelena [56]

Since each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must be completed twice to produce the four CO2, six NADH, two FADH2, and two ATPs.

  • Catabolic reactions occur within cells during cellular respiration. It is a biochemical process by which waste materials are removed and nutrients are broken down to generate energy, which is then stored in the form of ATP. The process of aerobic respiration needs oxygen.
  • The Krebs cycle, also known as the citric acid cycle, is the last step of oxidation for amino acids, lipids, and glucose.
  • Other than glucose, many animals rely on other substances for energy.
  • Protein's metabolic byproduct, amino acids, are deaminated and converted to pyruvate and other Krebs cycle intermediates.
  • They begin the cycle and are broken down, for example. On deamination, alanine turns into pyruvate, glutamate into -ketoglutarate, and aspartate into oxaloacetate.
  • Acetyl CoA is created when fatty acids are -oxidized and enters the Krebs cycle. It is the primary mechanism through which cells produce ATP. Complete nutrient oxidation results in the production of a significant amount of energy.

Identify the neurons described
rosijanka [135]

Answer:

<u>Motor neurons </u>send messages to the muscles and glands to respond to stimuli.

<u>Sensory neurons </u>move information towards the central nervous system for processing.

<u>Interneurons </u>carry information from one type of neuron to another.

Explanation:

  • Neurons are basic structural and functional units of Nervous system.
  • Neurons possess electrical excitability, the ability to respond to a stimulus and convert it into a action potential.
  • Neurons can be classified on the basis of their structure and function.
  • On the basis of structure neurons are classified as, Multipolar neuron;Bipolar neuron; Unipolar neuron.
  • On the basis of function neurons are classified as, Afferent or sensory neuron; Efferent or motor neurons; Interneurons or association neurons.
