people with type A blood will have the A antigen on the surface of their red cells (as shown in the table below). As a result, anti-A antibodies will not be produced by them because they would cause the destruction of their own blood.
Suppose that 22% of an organism's genome is the nucleotide guanine (G). What else do you know about the organism
An organism's genome is made up of the nucleic acids and some other macromolecules. The genetic material is the DNA and the DNA comprises the nitrogenous bases, deoxyribose sugar and a phosphate backbone.
Suppose an organism genome is made up of 22% guanine, then approximately, the amount of cytosine is 22% and that of adenine and Thymine is 28% each.
According to Erwin Chargaff, he deduced that Adenine pairs with thymine therefore their base composition will be equal . And that cytosine pairs with guanine and the same follows. Since guanine is 22%, it follows that cytosine would be 22%, then their addition gives 44%. 100 - 44 = 56/2 gives the composition of either adenine or thymine which is 28% each.Learn more: https://brainly.com/question/19156457

If a haploid cell has 16 chromosomes in its nucleus, how many would be present in the diploid state? View Available Hint(s) for Part A 4 8 32 64
Answer:
If a haploid cell has 16 chromosomes in its nucleus, how many would be present in the diploid state? A. 4. B. 8. C. 32. D. 64. C.
Explanation:
If the haploid cell has 16 chromosomes in its nucleus, then it has 32 chromosomes in the diploid state. The option saying "32" is correct for this condition.
What is a chromosome?
The chromosomes are present in the nucleus of the eukaryotic cell, and their number varies from species to species. One species may get 4 chromosomes while others, like humans, have 46 chromosomes.
The haploid cells are formed by the process of meiosis, where the cell gets half of its genetic content from the parent cell. If the haploid cell gets 16 chromosomes, then the parent cell, which is the diploid cell, gets 32 chromosomes. In the parent cell, there are two copies of a gene, one from the paternal side and one from the maternal side. The same genetic content is transferred to the daughter cells during mitotic division.
Hence, as a haploid cell is formed with 16 chromosomes, the diploid cell has 32 chromosomes.

What is Evolution? best answer will get a brainliest!
Answer
Evolution is basically just the process in which different types of organisms have devoloped.
Easier way of saying it:
The gradual development of something
usually from something simple to something complex.
Have a great day :)
Answer:
Evolution is the gradual change of characteristics and traits, that occurs within a species, over many generations.
Explanation:
Due to natural selection, some genes of a species can be passed on to their offspring, to increase chances of survival. This is because these new traits are enabling, the organisms who have them, to survive longer then the ones who don't, thus allowing them to procreate and have more offspring, who share that same trait.
This process can occur over several generations, and in turn, can really change a species.

Water is a source of ______________ for chemical reactions in cells. (a) hydrogen atoms (b) oxygen atoms (c) energy Both (a) and (b) (a), (b), and (c).
Answer:
A) Hydrogen Atoms
Explanation: Water provides hydrogen (H) and (O) atoms for making biological molecules.
Water is a source of both (a) and (b) for chemical reactions in cells. Water molecules have one oxygen atom in the center and two hydrogen atoms, one on each side which participate in chemical reaction.
what are the features of water molecule ?
Water is tasteless, odorless, or transparent, where oxygen atom having nucleus attracts electrons more strongly than the nuclei of the hydrogen atoms.
So oxygen is more electro negative and electron-greedy than hydrogen atom, resulting in the development of a partial negative charge on the oxygen atom of the water and a partial positive charge on the hydrogen end.
Water shows both cohesive and adhesive properties where adhesion of water molecules refers to stick to some other substance while cohesion is the property of water molecules to stick together.

If a population pyramid is shaped like a true pyramid, what can we determine about that population's growth?
Answer:
A population pyramid does not provide information about the actual population in terms of numbers. Another way to think about it is that the bottom of the pyramid is bigger than the top, indicating that a greater proportion of the population is in their reproductive years or has not yet reached reproductive age. As a consequence, there is a great deal of room for expansion.
Explanation:
Hope it helps:)
If a population pyramid is shaped like a true pyramid, with a wide base and gradually narrowing towards the top, it indicates a population with a high birth rate, a decreasing death rate, and a potential for rapid population growth.
A wide base of the pyramid suggests a larger proportion of young individuals, typically representing a high birth rate. This means that a significant number of babies are being born within the population.
As the pyramid narrows towards the top, it indicates a smaller proportion of elderly individuals. This suggests a decreasing death rate, meaning that more people are surviving into older age due to improvements in healthcare, nutrition, and living conditions.
The combination of a high birth rate and a decreasing death rate creates a population structure conducive to rapid growth. With a larger number of young individuals entering reproductive age in the future, the potential for continued high birth rates exists.

The enzyme machinery responsible for mismatch repair must be able to distinguish between the template strand and a newly synthesized strand. How is that achieved in a bacterial cell, such as E. coli
Answer: For a short period of time after replication, the sequence GATC is methylated at the A only on the template strand.
In recently manufactured DNA, a mismatch has been found. The template (old) strand's T is coupled with a G in the new strand.
What effects of mismatch repair in enzyme machinery?DNA damage causes the mismatch repair enzyme MLH1 to become active. However, MLH1 expression appears to be connected to apoptotic signaling.
As well as being necessary for damage repair, When it is activated, activities that result in planned cell death are triggered.
A region of DNA containing the mismatched nucleotide and its neighbors is removed, and the new DNA strand is cut. A DNA polymerase substitutes the missing nucleotides for the missing patch.
The mismatch repair machinery separates the newly synthesized strand from the template to start the repair process (parental).
Therefore, a short period of time after replication, the sequence GATC is methylated at the A only on the template strand.

Mendel was the Father of Genetics, who studied the inheritance pattern and explained the independent assortment, segregation, and dominance. The influence of one gene does not affect the other in independent assortment.
The correct answer is:
Independent Assortment
The law of independent assortment states that alleles of two or more genes get sorted into gametes independently. The allele received for one gene does not influence the allele received for another gene.
The example of independent assortment includes the combination found in pea plants, such as round shape and yellow color, wrinkled shape, and green color, and round shape and green color.
Therefore, the correct answer is independent assortment.

What term is used to describe the premise that increased ventricular filling improves contractile force of the heart as a result of greater stretch of cardiac fibers
Frank – Starling law is used to describe the premise that increased ventricular filling improves contractile force of the heart as a result of greater stretch of cardiac fibers.
According to the Frank – Starling law, the more the heart muscle is stretched during filling, the greater the contractile force and the greater the amount of blood pumped into the aorta are, as well as the ejection pressure.
This is because there is a relationship between cardiac fiber length (equivalent to end-diastolic volume) and force of contraction (equivalent to stroke volume).When an extra amount of blood reaches the heart, the heart muscle stretches more and is able to contract with greater force.Therefore, we can conclude that Frank – Starling law is used to describe the premise that increased ventricular filling improves contractile force of the heart as a result of greater stretch of cardiac fibers.

Which method do you think best represents energy flow through ecosystems? Why?
this needs to be a paragraph or two :)
Answer:
The circle of life, in which energy flows into the world from the sun, giving plants that energy to live. All of the organisms in an ecosystem are chemical machines driven by the energy captured in photosynthesis. The organisms that first capture energy, the producers, include plants, some kinds of bacteria, and algae. All other organisms in an ecosystem are consumers.
The plants energy will then be transferred to a small animal, most likely a rabbit or maybe a mouse; depending on the plant. The small animal will then be eaten by a bigger more dominating animal like an eagle or a snake. It just goes on and on. The eagle or the snake will get eaten by a bigger animal or will decompose into the earth giving the soil and plants around it that same energy.
BOOM UR WELCOME SWEETIE :)
The method that best represents the flow of energy through the ecosystem is known as the pyramid of energy.
What is an Ecosystem?An ecosystem may be defined as a type of place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
As well all know that the pyramid of energy is always upright in all sorts of ecosystems, whether it is grasslands or aquatic. This is because the energy flow from one trophic level is only 10% that has to be transferred to the next trophic level in all ecosystems.
This system of energy movement is so efficient that even a little energy can not be wasted. It all gets consumed by the next trophic level.
Therefore, the pyramid of energy is the method that best represents the flow of energy through the ecosystem.
