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.

Do all living things obtain the matter and energy they need to live and grow in the same way?
Answer:
Explanation:
This means all living organisms must obtain and use energy to live. Energy is the power to do things. ... A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis.
Living things obtain energy and food to grow but different organisms do in different ways plants depend on the sun for photosynthesis.
How do living things obtain energy?Every living thing has a unique method of getting nutrients. Protozoans and other animals are among the creatures that obtain nutrition by eating food. Through the process of photosynthesis, plants and algae produce their own sustenance.
Animals consume food and drink to get the substance and energy they require for their biological activities.
A producer is an organism that produces its own nourishment. Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.
Therefore Plants are one type of creature that can produce its own food, to obtain energy.

A researcher is investigating the of effects a chemical that makes thylakoid membranes permeable to hydrogen ions (H+). Which of the following is most likely direct effectof adding the chemical to plant cells?
Answer:
B. The chloroplasts will generate less ATP
Explanation:
Photosynthesis, occurs in the chloroplasts of plants. Solar energy is converted into chemical energy in the form of stable carbohydrates.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process. The thylakoid contains multiple folded membranes called granum stacked together. They contain light-absorbing pigments like chlorophyll.
Here, absorbed light is used in photolysis, to split water produce H+, O2 and high-energy electrons for the high-energy producing electron transport chain.
Protons are pumped into the stroma within granum, producing ATP. ∴ Without ATPase, less ATP is produced.
Chloroplasts are the membrane-bound organelles, which carry out the process of photosynthesis. The correct answer is:
Option B. The chloroplasts will generate less ATP.
Photosynthesis is the process of preparing the food in presence of sunlight. It occurs in the plant. The chloroplasts are the membrane-bound organelles, which consists of pigments, enzymes, and other molecules. The thylakoid membrane consist of stacked membranes, known as grana. The light-absorbing pigment, chlorophyll is found in grana.
The following points can be used to explain photosynthesis:
The absorbed light initiates photolysis, which is the breakdown of water molecule into hydrogen and oxygen. During photolysis, high-energy electrons are also released. These electrons are utilised in the electron transport chain to provide energy.Therefore, the permeability of the protons into the granum will yield ATP. The less ATP will be produced without ATPase.

Describe two mating systems, and explain why different systems exist.
Answer:
It depends on their life expectancy. There is an bird that is born and dies on the same day (sorry I cannot remember the name) so as soon as they can mate, they mate until death. Not every animal mate for life because they live longer. Animals that mate for life mate because they have a short life so they do this to continue the population.

In essence, DNA is a thin and very, very long organic molecule. It is a polymer, and each of the monomers that constitute it are called ______
Answer:
nucleotides
Explanation:
DNAs are long-chain, helical macromolecules that store genetic information They are made up of varying sequences of covalently bonded monomers called nucleotides. Four types of nucleotides make up the nucleic acid DNA, these include Adenine, Guanine, Cytosine and Thymine.
Unlike other macromolecules, these are typically not used as an energy source and only encode protein synthesis. They comprise a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
Nitrogenous bases encourage base-pair formation through hydrogen bonding. Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.

Which compound is a reactant in cellular respiration?
oxygen
carbon dioxide
water
ATP
Answer:
Oxygen
Explanation:
........... ......
Oxygen and glucose are the reactant in process of cellular respiration. ATP is the primary product of cellular respiration, and carbon dioxide and water are waste products. Thus, option A is correct.
What is the importance of cellular respiration?During the process of photosynthesis, which creates glucose from water and carbon dioxide, solar energy is transformed into chemical energy. The byproduct is the emission of oxygen.
In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
The terminal electron acceptor in cellular metabolism is oxygen. H2O is produced when oxygen takes hydrogen ions and electrons.
After passing via ATP synthase, hydrogen ions from the intermembrane space move from the mitochondrial matrix to produce ATP.
Therefore, oxygen molecule is a reactant in cellular respiration.

We use blank as the matrix through which DNA will travel. In order to physically see the samples that we put in the gel, we first have to add blank to each sample. When we have the samples loaded, we want to make sure we also add what's called a blank which acts as the standard curve in a tube; it's made up of DNA fragments of known sizes. Before running the gel, it's important to make sure that there is blank covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool
Answer:
This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:
1) GEL
2) DYE
3) DNA MARKER
4) LID
Explanation:
This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.
In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.
