What would happen if a freshwater fish didn't produce lots of watery urine? a. The fish would shrivel.
b. The fish would swell.
c. Water would move out of the fish by osmosis.
d. Water would be pumped out of the fish.

Answers

The right answer for the question that is being asked and shown above is that: "c. Water would move out of the fish by osmosis." if a freshwater fish didn't produce lots of watery urine, then water would move out of the fish by osmosis.

How and why do cells reproduce

Answers

Cells reproduce for 3 reasons

-Repair
-Growth
- And to make new kinds of cells

And how they reproduce

Scientists call the process of somatic cell division mitosis. Mitosis has six distinct steps in which the cell organizes and copies the DNA in the nucleus. Once copied, each new cell has its own copy of the DNA. The six steps of mitosis are prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Some authorities consider the non-dividing portion of the cell’s lifecycle, known as interphase, to be one of seven steps involved in mitosis; however, interphase cells are not actively dividing. Sex cells, such as sperm or eggs, must divide differently. Sex cells only possess one-half of the DNA that makes up a new animal. That way, when they combine, the resulting organism gets half of its DNA from its mother and half from its father. Because sex cells only want half of the DNA in each cell, they go through a different division process called meiosis. In meiosis, the cells split a second time, which yields four daughter cells rather than two as with mitosis; however, this provides each daughter cell with 23 chromosomes in contrast to the 46 chromosomes in somatic cells.

Lack of vitamin C in the diet interferes with the ability of fibroblasts to produce collagen. What effect might this interference have on connective tissue?

Answers

Answer:

Answer is given below:

Explanation:

Function of vitamin C is healing wounds. Its deficiency causes multiple effects on connective tissue. It decreases the amount of collagen synthesis and angiogenesis and increases the amount of fibroblast and also increases capillary fragility and definitely because of its deficiency wound will not be healed properly or may not be healed.

Which object in space emits light because it releases energy produced by nuclear fusion?

Answers


My answer to this would be the sun

Final answer:

The Sun is the object in space that emits light due to the energy released from nuclear fusion in its core. This process involves the fusion of hydrogen nuclei to form helium, releasing energy as photons, neutrinos, and gamma rays. The released energy, particularly the photons, is therefore responsible for the Sun's light.

Explanation:

The object in space that emits light because it releases energy produced by nuclear fusion is the Sun. This nuclear fusion takes place in the Sun’s core and involves the combination of two hydrogen nuclei to form helium, releasing energy in the process. This energy is released as light and other particles such as neutrinos and gamma rays.

In detail, the nuclear fusion reaction in the Sun converts about 10³8 protons per second into helium at a temperature of 14 million Kelvin. The energy produced manifests as photons (light), neutrinos, and other particles. The neutrinos and gamma rays escape the Sun's core and propagate out into space.

The energy from this nuclear fusion diffuses slowly towards the surface of the Sun, lighting up the Sun and ultimately, our Earth. It's worth noting that though this process destroys mass, the amount of energy release, known as the Q value, is incredibly large, affirming the application of Einstein's mass-energy equivalence principle, E=mc².
