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.

Considering ethical questions is part of a marine scientist’s job. Part of being ethical is doing your homework and exploring all sides of an issue. Choose a current ethical issue in marine science, such as the use of genetically modified organisms (GMOs), conditions in fish farms, or another topic your instructor approves. Find two perspectives supporting one side of the ethical issue and two supporting the other. Be sure to use reliable sources, such as university web sites or newspaper/magazine articles. Create an outline with at least five points for each side. Then write a brief paragraph explaining what you believe an ethical choice around this issue is. Remember, ethical problems are difficult because both sides have valid points. Be sure to consider and discuss at least one point you think is valid from the side that you disagree with in your conclusion as you explain why your choice is the ethical one. Also, include a list of sources that you used. Two is the minimum for each point of view.

One current ethical issue in marine science is the use of genetically modified organisms (GMOs) in aquaculture.
What are genetically modified organisms?Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering techniques.Here are two perspectives supporting each side of the issue:
Perspective 1: According to a report by the World Health Organization (WHO), GMOs have the potential to reduce the environmental impact of aquaculture by decreasing the need for wild fish as feed, reducing the use of antibiotics, and decreasing the risk of disease outbreaks.
Perspective 2: Opponents of GMOs in aquaculture argue that they pose a significant risk to wild fish populations and the environment. According to the Ocean Conservancy, GMO fish can escape from fish farms and breed with wild fish, potentially altering the genetic makeup of natural populations and harming biodiversity.
Therefore, use of GMO's is profitable as well as hazardous for the environment.

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.

2. fish
Explanation:
As per the given scenario, The best source of vitamin C is strawberries, while fish is naturally rich in vitamin B12. The correct option for first blank is B, and for second one is A.
What are vitamins?A vitamin is an organic molecule that is an essential micronutrient that an organism requires in small amounts for proper metabolism function.
Fat-soluble vitamins are stored in the liver, fatty tissue, and muscles of the body. Vitamins A, D, E, and K are the four fat-soluble vitamins.
Water-soluble vitamins do not accumulate in the body. Vitamin C and all of the B vitamins are among the nine water-soluble vitamins.
As per the given scenario, The best source of vitamin C is strawberries, while fish is naturally rich in vitamin B12.
Thus, the correct option for first blank is B, and for second one is A.

The earth , the sun , and the seven other planets that are in orbit around the sun are part of the solar system. How does the size of the solar system compare with the size of the milky way galaxy ?
Answer:
Size of milky way galaxy is very large than our solar system.
Explanation:
The size of the solar system is much smaller than the size of the milky way galaxy because our solar system is a part of milky way galaxy. The radius of our solar system is 4.545 billion km while on the other hand, the radius of the milky way galaxy is 52,850 light years which is very very large than the radius of our solar system. Milky way galaxy has 100–400 billion planets while in our solar system has only eight planets.
1- why dong you usually get sick from the exact same pathogen twice
2-if a pathogen mutated so it had different antigens, would your memory B and memory T cells recognize it?
please help this is due at 3pm
1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.
2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.
The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus

Once pollen lands on the stigma, it forms a pollen ____________________ down through the long_____of the pistil [the female reproductive part] into the flower's ______– which contains ovules. fill in the blank
Answer:
1. Pollen tube
2. Style
3. Ovary
Explanation:
This process is describing the process of POLLINATION, which is the transfer of pollen grains from the anther of a male flower (androecium) to the stigma of the female flower (gymnoecium). After pollination i.e. the pollen has landed on the sticky stigma, the pollen grows out a tube called POLLEN TUBE.
The pollen tube extends through the STYLE of the female flower called PISTIL to the OVARY. The ovary is the reproductive part of the female flower that produces the ovules, which the sperm in the pollen is about to fertilize.

In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?
Answer:
Three different genotypes and two different colors
Explanation:
Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.
hope this helps!
The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).
According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b). If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb. BB - black offspringBb - black offspringbb - white offspringTherefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).Learn more at: https://brainly.com/question/3712307?referrer=searchResults
