Why can a planet orbit circular?
Answer:
Explanation:A circle is merely a special case of an ellipse. However, the planets do not quite move in ellipses either. The increased kinetic energy of a planet as its distance from the Sun decreases causes it to behave as though it had a greater mass, which results in the point of the orbit furthest from the Sun precessing.
Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG codons are in the 'zero' reading frame, in- frame with the AUG initiation codon. The effect of increased numbers of CAG repeats on the encoded protein is:___________. a. to silence of the gene to generate a truncated protein b. to generate a protein with a run of consecutive glutamines c. to generate a frameshifted protein product d. none of the above
Answer:
The correct answer is - option b. to generate a protein with a run of consecutive glutamines.
Explanation:
The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.
So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.

Q: Predict and describe some possible effects to your entire food web if the following happened:
A mysterious virus has sickened the secondary consumer fish. There
are few survivors. Fortunately, this virus is not affecting organisms on any other trophic levels. However, the loss of these organisms is
affecting the rest of the food web. Please describe the possible effects:
Answer:
Less fish will disrupt the predators in the ocean. Sharks, and other predators in these oceans need a food source such as fish if this Virus does indeed kill these many fish. Meaning the virus is in this fish, It might spred to predators that eat these fish. Still if the predators of the food chain dont find these food sources for them i am sure they will die of starvation.
Explanation:
If a food source for animals is obsulete i am sure the predators of the animals will have starved to death like how, the Hot blob is affecting the Cassins auklet due to the Less amount of phytoplankton in the oceans.1. Which items best describe a desert?

How many valence electrons does Neon have and does it have cations and anions???
Answer:
Neon has eight valence electrons and it does not have cations or anions.
Explanation:
Neon is a noble gas, meaning it has already fulfilled the octet rule and has eight electrons in its valence electron shell. Hence, it does not want to lose or gain any more electrons, and does not have cations or anions.
Hope this helped!
Answer:
Neon has eight valence electrons and it does not have cations or anions.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.
Answer:
The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.
Explanation:
Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.
The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.
The function the eyes performs requires more precise locomotion control than the movement of the limbs require.
For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.
This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.
In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

Which part of photosynthesis is represented by the diagram to the right
Answer:
Light-dependent reactions
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).

A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?
Answer:
7250 WBC/ml
Explanation:
The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us
10,000 + 4,500 = 14,500 WBC/ml
The mean then is
14,500 / 2 = 7250 WBC/ml
Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml
