Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2).
Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.
how to write a narrative story?
Answer:
Start with action or dialogue.
Ask a question or set of questions.
Describe the setting so readers can imagine it.
Give background information that will interest readers.
Introduce yourself to readers in a surprising way.
Explanation:
Answer:
Narrative essays/stories are often anecdotal, experiential, and personal—allowing students to express themselves in a creative and, quite often, moving ways. So, in short, it's an essay about your life with details, events, etc.
Explanation:
Narrative essays/stories should include:
an introduction, plot, characters, setting, climax, and conclusion.must have a purpose; think of this as the thesis of your story.the essay should be written from a clear point of view; essays to be written from the standpoint of the author (you); however, this is not the sole perspective to be considered. Creativity in narrative essays oftentimes manifests itself in the form of authorial perspective. narrative essays are effective when the language is carefully, particularly, and artfully chosen. Use specific language to evoke specific emotions and senses in the reader. the use of the first person pronoun ‘I’ is welcomed; though it is welcomed it is not necessary—nor should it be overused for lack of clearer diction.have a clear introduction that sets the tone for the remainder of the essay. Do not leave the reader guessing about the purpose of your narrative; you are in control of the essay, so guide it where you desire (just make sure your audience can follow your lead).I hope that this helps you! I know it was a lot to read, but it's worth it. Have a nice night! :D

Although the liver and the pancreas are not part of the digestive tract, they are important to the process of digestion because: a. Secretions they produce help to digest food b. They absorb nutrients into the bloodstream c. They eliminate wastes from the body d. All of the above
Answer:
The correct answer is - d. all of the above.
Explanation:
The liver and pancreas are not part of the digestive tract but they play a very major role in the process of digestion. The liver and pancreas both produce and secretes the enzymes and bile to breakdown the food into nutrients. Bile digests the fat while enzymes of the pancreas break down protein, carbohydrates, and fats.
The liver helps in absorbing the fats and some vitamins and minerals to the bloodstream from the nutrient from digested food. They also help in the removal of toxins and wastes from the digested food or the waste products of breaking down into nutrients through the feces or filtered from the blood by the kidneys.

as the hare population increases there is in increase in the lynx population explain why this occurs
Answer: The lynx population increases as the hare population increases because there are more prey for the lynx to eat. The Lynx population also increases because there is more food for them to eat. What does the increase in the lynx population lead to? It leads to a decrease in the hare population because the lynxes were eating the hares. What happens to the lynx population when the hare population goes up? Continued predation due to high populations of lynx and other predators increases the hare population decline. ... As hare numbers start to decline, lynx continue to eat well because they can easily catch the starving hares. When hares become scarce, lynx numbers also decline.
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
The changes in the population of one species can have a significant impact on the population of another species within the same ecosystem. Therefore, when hare population increases, there is in increase in the lynx population as well.
What is predator-prey cycle?A predator-prey cycle is a cycle where if the prey population increases in size, it leads to an increase in predator population size due to availability of more food.
The relationship between the hare and lynx populations is a predator-prey dynamics. When the hare population increases in size, the lynx population also increases due to availability of more food.
When there are more number of hares, the lynx hunts them more easily which causes an increase in lynx population. However, the increase in lynx population leads to more consumption of hares, that leads to decrease in the hare population. With fewer hares available, the lynx population then starts to decline leading to a cyclical pattern of population growth and decline.
Therefore, this type of relationship is a predator-prey cycle which describes changes in the population of one species can have a significant impact on the population of another species within the same ecosystem.
