The half-life of Uranium-235 is 700 million years. The correct answer is option D.

Half-life is the time period taken by the radioactive atoms to decay and to decrease to half of the original number of radioactive atoms that were present initially. The half-life of a radioactive element tells about the rate at which it decays and releases radiation

Uranium has thirty-seven different isotopes. Uranium-235 is an isotope of uranium. This isotope is important because it releases a large amount of energy on splitting. It is not highly radioactive as it releases less radiation.

Here, it is given that the Uranium sample initially contains 200 atoms which decrease to 100 atoms after 700 million years which is half of the initial number of atoms in that sample. so the half-life of the Uranium-235 sample is 700 million years.

Explanation:

Not only is the biota important, but the abiotic factors in the ocean are also important because both groups work together. The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize.

Answer: Equilibrium is the condition of a system in which competing influences are balanced, resulting in no net change. However, homeostasis is the ability of a system or living organism to adjust its internal environment to maintain a state of dynamic constancy; such as the ability of warm-blooded animals to maintain a stable temperature

Explanation:

This is active transport so the ions go against the concentration gradient. This means that the ions will travel from the place where there are less sodium ions(from the inside of the cell) to the place where there are more sodium ions (to the outside of the cell).

Answer:

77.5lbs

Explanation:

Weight × Pluto's surface gravity

125 x 0.62 = 77.5

A 125-pound person would weigh 7.5 pounds on pluto because of its low gravity.

The force that pulls materials toward the center of a planet or other entity is called gravity. All of the planets are placed in orbit around the sun by gravity.

Weight is the gravitational force that pulls objects towards the center of the Earth. The resulting force that pulls a mass toward Earth is called gravity. In contrast to gravitational force, which occurs between any two masses, this only happens between Earth and a mass. The gravity of pluto is one-fifth of the earth's gravity. Therefore, weight is experienced less on pluto and more on earth.

Thus, a 125-pound person would weigh 7.5 pounds on pluto because its gravity is low.

Explanation:

Blood type is one of the traits we inherit from our parents. There are three different alleles that determine it: A, B, and O. Their combination can produce four different blood types: A, B, AB, and O.

If a person has blood type A, their genotype is either AA or AO. The child's exact genotype will depend on the mother's, which we are not provided with. Her blood group is either A, O, or AB. The child definitely inherited one A allele from its father, and the second allele (A or O) had to be inherited from the mother. Her genotype can be AA, AO, AB, or OO. What matters is that her genotype contains one A or one O allele. That is how we can get a child with the AA or AO genotype if its father has the AB genotype.

According to the International Astronomical Union, which sets definitions for planetary science, a dwarf planet is a celestial body that -orbits the sun, has enough mass to assume a nearly round shape, has not cleared the neighborhood around its orbit, and is not a moon.

Explanation:

Hope this helps :)

Answer:

The reason these as well as our moon aren't considered planets or dwarf planets is because their natural satellites of actual planets. They orbit the planet that orbits the sun. So that's why they're not considered planets, even though several are bigger than Mercury.

Answer:

B

Explanation:

Mitosis is how cancerous cells reproduce (well, it's more of a gene mutation that makes them over reproduce; or they go through the mitosis phase much more often and quicker than is needed) If you prevent mitosis, then they can't reproduce

A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. It could these be helpful in the treatment of tumors by preventing tumor cells from reproducing. Therefore, the correct option is B.

Mitosis inhibitors are a type of chemotherapy medication that interfere with the process of cell division, preventing cells from progressing through the various stages of mitosis. This can be particularly effective in the treatment of cancer, as tumor cells typically divide and grow more rapidly than normal cells.

By preventing tumor cells from dividing, mitosis inhibitors can help to slow or stop the growth of a tumor. This can also make the tumor more vulnerable to other treatments, such as radiation therapy, which may be more effective against actively dividing cells. Therefore, the correct option is B.
