What blood types are possible for a child whose parents both have AB bloodtype?I. AII. BIll. ABIV. OA. Only IB. Ill and IVC. I and IlD. I, Il, and Ill
They are asking us the possible blood types for a child of parents with AB blood type.
This means that both parents have one allele for antigen A (Iᵃ) and one allele for antigen B (IᵃIᵇ):
Mother: IᵃIᵇ
Father: IᵃIᵇ
Just from that, the child cannot be type O, because there is no allele for not having any antigen (i).
Let's look at the Punnet's square:
As we can see, the child of this couple could have blood type A, B, or AB.
This means the right answer is D. I, Il, and Ill

Explanation:
Endotherms are able to maintain a constant internal body temperature. Which is one property of endotherms that allows them to complete this task?A: well-developed lungs that deliver oxygen to the bloodB: a low metabolic rate that releases a small amount of heatC: an insulated body covering, such as fur or feathersD: a thin skin that readily absorbs heat from sunlight
The correct answer is the letter C: an insulated body covering, such as fur or feathers
Endotherms mainly use internally generated heat in order to maintain body temperature. This will cause their body temperature tends to stay steady regardless of the environment. On the other hand, ectotherms depend mainly on external heat sources and their body temperature changes with the temperature of the environment.
Examples of endotherms are birds and mammals
Examples of ectotherms are fishes, amphibians, reptiles, and invertebrates.
Based on the result, which is the most effective antibiotic in this example?1234
What we see around three of the antibiotic disks is the area in which the antibiotics stopped the bacteria from growing. It's called a zone of inhibition and it creates an area where the bacteria haven't grown enough to be visible. So, in order to understand which is the most effective antibiotic we must look at its zones of inhibition and find the one with the biggest zone. Therefore, the correct answer is 3, as it is the one with the bigger zone of inhibition.

Would the absence of the nucleolus affect the process of protein synthesis? Explain
(HELP NEEDED BY THE NEXT FEW HOURS. THANK U SO MUCH)
The absence of nucleolus will affect the process of protein synthesis because r-RNA is required for protein formation and the synthesis of r-RNA occurs in the nucleolus.
Nucleolus is a small dense structure present inside the nucleus. It is site for r-RNA synthesis. Ribosome assembly also takes place inside the nucleolus. Nucleolus is also known to play part during cell's response to stress.
r-RNA is the ribosomal RNA. It is involved in the formation of ribosome along with some proteins. Ribosome is the most essential machinery for the synthesis of proteins. r-RNA belongs to the category of non-coding RNAs. r-RNA is considered to be a ribozyme.

Why natural selection is not just a theory?
In science, the meaning of "theory" is different than the one we use commonly.
In the day-to-day, "theory" means a supposition or speculation, while a scientific theory is an explanation of a certain aspect of nature that is supported by evidence collected from several sources, and that has been tested repeatedly following the scientific method. A scientific theory is considered to be a truth, which is the case for natural selection and evolution.
In this process humans would select animals or plants with a trait they desire then breed those organisms to produce more individuals with the desired traits.Natural selectionContaminationInseminationArtificial selection.
The correct answer is Artificial selection.
Humans interfere in the natural process of organisms that they slect the desirable trait for the organisms that they think best will help the organisms to adapt well into their environment.
How do trees give earth all its oxygen?
*Oxygen is an essential element in the atmosphere that helps living organisms stay alive.
*Tress gives Earth oxygen through the process of photosynthesis. Plants, such as trees, capture sunlight and use it to split carbon dioxide and water. The product of it is sugar which releases oxygen into the atmosphere as a by-product of the process.

Answer: Which example best describes a computer model that could be used to better understand the function of the brain?
A. A simulation predicting the paths of electrical impulses through the brain is the best example of a computer model that could be used to better understand the function of the brain.
Explanation:
In this simulation, a computer program would be used to create a virtual representation of the brain and simulate the movement of electrical impulses along different pathways. This can help researchers and scientists study how the brain processes information and how different areas of the brain communicate with each other.
By using this computer model, scientists can observe the patterns and pathways of electrical activity in the brain, which can provide valuable insights into how the brain functions. This can help in understanding various neurological disorders and developing treatments for them.

The hemophilia gene is an X-linked recessive gene. This means that a person will be hemophiliac if has two copies of the recessive "h" allele (in the case of females) or if has one copy (in the case of males). This also means that if the individual possesses the dominant H allele, he or she will not have hemophilia. Therefore, when performing the punnet table of section 2, we can observe that only one of four descendants would present hemophilia and in this case, it would be a male with genotype X^h Y (25% male), and only one of four would be a carrier that doesn't present hemophilia and in this case, it would be a woman with genotype X^H X^h (25% female)

Write the balanced equations for the process of your organism uses to make food / energy ( Photosynthesis , respiration, or both).My organism is great white shark
Photosynthesis is a mechanism of sugar production that is carried out by plant organisms possessing chloroplasts. Most animals cannot perform photosynthesis because they do not have chloroplasts, the great white shark is one of them.
On the other hand, respiration is a mechanism for obtaining energy that is performed by all organisms, which can be aerobic (in the presence of oxygen) or anaerobic (in the absence of oxygen). In cellular respiration, sugars such as glucose are metabolized to obtain energy.
The equation changes depending on the type of breathing that is performed, but in this case, the white shark performs aerobic breathing, so the equation would be:

Which dissolved substance do aquatic plants absorb from water during photosynthesis The choices are: carbon dioxide, ATP, oxygen, nitrogen
In the case of aquatic plants those that are totally submerged like seagrass, do photosynthesis as well as terrestrial plants, which need light carbon dioxide and expel oxygen. However, carbon dioxide in water dissolves so aquatic plants obtain it not in a gaseous way but in a dissolved way, so we can say that he correct answer is carbon dioxide.
Is the trait (blue) in the pedigree most likely caused by the presence of a dominant or recessive allele?Group of answer choicesrecessivedominantneitherboth
The blue trait is most likely caused by a dominant allele (e.g. allele A), while the white trait is caused by a recessive allele (allele a). However, for the diagram to be correct, individuals 1I and 2I must have genotypes Aa (blue) and aa (white) respectively, thus making the punnet squares, the genotypes of their offspring would be Aa (blue) and aa (white). In turn, we can verify that this is correct by observing the third generation since if the blue individuals of the second generation had genotype AA, they could not have white offspring (aa). If we make all the crosses, the genotypes would be as follows:
1 I: Aa 2 I: aa
1 II: Aa 2 II: aa 3 II: aa 4 II: aa 5 II: Aa 6 II: aa 7 II: Aa 8 II: Aa
1 III: Aa 2 III: aa 3 III: aa 4 III: aa 5 III: aa 6 III: Aa or AA 7 III: aa 8 III: Aa or AA 9 III: aa
