Answer:
Both are heteroproteins with a globular structure.
Explanation:
Both proteins are very similar, myoglobin is usually relatively small in size compared to hemoglobin.
Both proteins are considered heterogeneous because they are globular, because of their globular shape and the order of union between their amino acids.
The center of these proteins is iron, which is why they are capable of transporting gases such as oxygen, carbon dioxide (CO) and NO.
The structures that make them up are known as heme groups, these heme groups can also be found in meats of animal origin, it is as well as inside the erythrocyte, there is hemoglobin, which contains the heme group with a divalent iron capable of be oxidized to transport this oxygen in the form of oxide, towards the myoglobin that will receive it in the muscular tissue, and consequently oxygenate the muscular tissues as well as other tissues during locomotion or physical action.

which of the following is not a reactant needed for photosynthesis
A. sunlight
B. oxygen
C. carbon dioxide
D. water
Answer:
I think it B
Explanation:
By definition of photosynthesis, oxygen is not a reactant needed for photosynthesis.
First, you have to know that photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.
With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.
Photosynthesis takes place in 2 stages:
In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O2).The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.
This is sunlight, carbon dioxide and water are reactants needed for photosyntesis, and oxygen is not a reactant needed.

please mark as the brainliest (ㆁωㆁ)
Answer:
B, in the cytoplasm
Explanation:
Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. This question is worded quite strangely, as the nucleus is an organelle it would make better sense to say in the organelles but it refers to organelles as plural and it's not in any other organelle but the nucleus, the cytoplasm is what surrounds the organelles and has direct contact with the cell membrane, the nucleoid also does not contain any enclosing membrane

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because she did not believe the new formula helped plants grow better than the old formula. it was necessary to see data from more plants before the conclusion could be accepted. it was necessary to have tested the fertilizer on different kinds of plants. she thought he should test additional fertilizer formulas on the same two plants.

What are possible products of glycolytic, or anaerobic, catabolism?
Answer:
The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.
Explanation:
Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.
Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.
Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.
This hormone has the opposite effect to glucagon.

Answer:
A hydrocarbon reacts with oxygen
Explanation:
The clue that can be used to identify a chemical reaction as a combustion reaction from the options would be if a hydrocarbon reacts with oxygen.
Basically, a combustion reaction is a kind of reaction involving oxygen and another reactant with energy being released in the process. The energy is usually in the form of light and heat.
Thus, following the definition:
Oxygen is rather a reactant, and may not be a product in combustion reactionsWater reacting with carbon dioxide is not a combustion reactionReaction involving ions may not be a combustion reactionThe only reaction that may identify as a combustion reaction is, therefore, the one involving hydrocarbon and oxygen.

Which of the following statements concerning ribosomes is true?
A. Several ribosomes are often attached to and translating the same MRNA.
B. Ribosomes join amino acids together to form a polypeptide.
C. Ribosomes have one binding site for MRNA and three binding sites for 1RNA molecules.
D. Ribosomes are the organelles responsible for protein synthesis.
E. All of the above statements are true.
Answer:
E. All of the above statements are
Explanation:
Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.
A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).
Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.
The correct answer is:
Option E. All of the above statements is true.
The explanation for the above option is:
The ribosome is located either free or is connected to the endoplasmic reticulum(RER).Ribosomes assist in the translation of the information from mRNA.Polysomes are numerous ribosomes connected to a single mRNA molecule.Ribosomes have one binding position for mRNA and three binding positions for tRNA molecules.The three binding sites for tRNA is (A- site) amino acyl site, (P-site) peptidyl site and (E site) the exit site.Ribosome assembles amino acids to form a polypeptide chain. These polypeptides get transported to the cytoplasm.Therefore all the above statements are true for ribosomes.

In the thylakoid membranes, what is the main role of the antenna pigment molecules?
a) split water and release oxygen to the reaction-center chlorophyll
b) harvest photons and transfer light energy to the reaction-center chlorophyll
c) synthesize ATP from ADP and Pi
d) concentrate photons within the stroma
Answer: Option B.
harvest photons and transfer light energy to the reaction-center chlorophyll
Explanation:
In the thylakoid membranes,the main role of the antenna pigment molecules is harvest photons and transfer light energy to the reaction-center chlorophyll because the photon of light move until it get to a molecule in the chlorophyll. When it reaches the molecule, it causes an excitation of electrons in the chlorophyll. The energy then present allow it to break free from the chlorophyll atom, which indicate chlorophyll donating an electron and the energy that is absorbed is then converted to heat.
Water has the property of having a high specific heat. This trait has a great influence on maintaining homeostasis within the body. Which of the following accurately explains what it means to have a high specific heat
Answer:
We can write the specific heat as:
C = (dU/dT)
Where C is the specific heat, U is the internal energy and T is the temperature.
This is:
"How much does change the internal energy when the temperature changes".
Having a high specific heat (and positive) means that for every little increase in the temperature we will have a large change in the internal energy.
What does this mean?
Think in the inverse way:
A larger specific heat means that we need a large amount of heat (the heat is energy) to change a little the temperature.
Then this is good, because even when receiving a lot of heat, the body temperature will remain about the same.
