How is the small intestine designed to absorb digested food ?
Answer:
Small intestine is designed to more and more area for absorption of digested food and transfer into the blood for circulation throughout the body. The inner lining of small intestine has a large number of finger-like projections called villi. These villi provide a large surface area for absorption of food.
Explanation:
Hope this helps!
Have a good day or night!
➜ The small intestine is the main region for the absorption of digested food. The inner lining of small intestine has millions of tiny finger-like projections called villi. The presence of villi gives the inner walls of the small intestine a very large surface area for absorption of digested food. The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body.

Explanation:
In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.
1) what is the genotype of the spotted (recessive) parent?
Answer:
the spotted parent has the genotype ss
Explanation:
we will use s as the letter when describing the spotted trait.
since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss. the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.

Given the following sequence of DNA, write the correct sequence of complementary DNA bases.
TACCGATAA
Given the following sequence of DNA, write the correct sequence of complementary mRNA.
ACCGTACTG
Given the following sequence of DNA write the correct sequence of amino acids.
ATAGGCGTA
Answer:
1. ATGGCTATT
2. UGGCAUGAC
3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)
Explanation:
For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them. The first three letters of the amino acid are the abbreviation.
Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?
Answer:
Immunization is one of the most effective processes of preventing or treating dangerous disease. It should be told and advertise to the general public about the facts and importance of vaccination. Doctors and government should explain the reports and ratio that the people who are taking the vaccination in the proper dose and the right amount of vaccination are about 9 timeless likely to have to the other people. It is essential to get a proper dose and proper amount to avoid the development of resistance.
There are several forms of vaccine and they have a different schedule from each other. Every vaccine is safe but one needs to know the cycles, dose and amount of the vaccine. Yes, we should spread out the inoculation schedule to prevent confusion of a young person.

Which factors affect the gravitational force between two objects?
Answer: The size of each object and the space between them.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Describe three ways in which economies are
likely to be affected by climate change
Answer:
1. Climate change affect the geography within which economy of the world operate
2. It changes the comfortability of human within the global industry
3. Growth Zone is affected
Explanation:
1. Climate change affect the geography within which economy of the world operate: economic of the world are affected by change in climatic condition in the since that there is shift in the usual period of seasons. For example, taken Nigeria as a region in West Africa, rainfall is expected to start around March in almost all part of the country, however, due to climate change, some part don't still have rain till May. This causes a shift in farmers plan and affect the supply of farm produce to the local market and to the global market, in turn affecting the gross domestic product of the country.
2. It changes the comfortability of human within the global industry. Take for example, fossil fuel, it is part of human being to address some unfavourable conditions among which is climate change which causes global warming, during this period, the way industries and people uses fossil fuel are been changed and it have direct effect to global economy.
3. Growth Zone is affected: change in climatic condition changes world economy growth zones. Thus could be seen in transportation sector, when the water level is affected, international movement of cargoes by ship are affect and hence, some trades agreements are altered thereby changing the growth zone.

present at a high concentration?
Answer:
A. Repressor proteins can be activated and bind to regulatory sequences to block transcription.
Explanation:
its A
The best explanation for the prokaryotic expression of a metabolic protein is repressor proteins can be activated and bind to regulatory sequences to block transcription.
What are metabolic proteins?Protein helps with growth and repair. Proteins have the potential to serve as a metabolic fuel source in addition to all of these important functions.
Excess proteins must be converted into glucose or triglycerides and used to provide energy or build energy reserves because proteins cannot be stored.
Thus, the correct option is A.

Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
Answer:
Question 6: The answer is the energy, because it collects more energy than the cow. When the cow eats plants, the energy from the plant decreases leaving the cow with only little amount.
Question 7: I agree, Because plants holds way more nutrients and energy than meat. I could support that by saying when a herbivore eats from a plant, It only recieves 10%.

Challenge question! Imagine the following situation. You receive a viral vector coronavirus vaccine that uses a specific adenovirus and your immune system mounts a strong immune response. At the same time, your friend receives an RNA coronavirus vaccine and also has a strong immune response. One year later a new coronavirus variant emerges and neither of the original vaccines protect people from this new variant.
A new viral vector vaccine is developed to the variant using the same adenovirus as before. In clinical trials, it is found that the new vaccine protects people that originally received the RNA coronavirus vaccine that your friend had but does not protect people that originally received the viral vector coronavirus vaccine that you had.
Question: Can you think of an explanation for why the new vaccine didn’t protect you, but did protect your friend?
Answer:
she took more care of her self and her immune system its more advance rather than the other person!
Explanation:
Due to being more careful meaningly taking care of not catching it, but also just cause you had it doesnt mean you're going to be carless "free" because you got the vaccine.
your friend could've been protected even though she had the vaccine she was not carless unlike the other person she thought about her actions.

kudzu quidity grew out of control. Why can introducing a new species to an existing ecosystem often be a disaster?
A The new species can create excess nutrients in the soil that can damage native species
The series can harminative anime and damage the ecosystem
Answer:
Due to lack of biological gent.
Explanation:
Introducing a new species to a new ecosystem often leads to a disaster because of the absence of bioagent for that species. Bioagent are those organisms which has the ability to control other organisms by feeding on them. A new species does not make problem in its old or original ecosystem due to the presence of controlling agents but in the new ecosystem there is no bioagent that can stop its growth so that's why sometimes the introduction of new species leads to a disaster.
