If child X has type A blood and father Y has type AB blood, what are the child's possible genotypes?
Answer:
AA, AO
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.
What is the difference between homeostasis and equilibrium
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

A uranium-235 sample starts with 200 atoms, and 700 million years later,
there are 100 atoms. What is the half-life of uranium-235?
A. 350 million years
B. 235 years
C. 100 years
D. 700 million years
The half-life of Uranium-235 is 700 million years. The correct answer is option D.
What is half-life?
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.

describe their effect on ecosystems.
Answer:
Explanation:
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.

how much would a 125 pound person weigh on pluto
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.
What is gravity and how it affects the weight of a person?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.

A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. How could these be helpful in the treatment of tumors? A. It would prevent carcinogens from entering the cell. B. It would prevent tumor cells from reproducing. C. It would force the cells into binary fission. D. It would force the tumors to enter telophase,
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.
What is a mitosis inhibitor?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.

How is air density related to the global wind patterns we see on our planet? *
Answer:
For example, air with a large amount of water vapor is less dense than dry air because the water molecule has less mass than either an individual nitrogen or oxygen molecule. Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earth's surface also forms large global wind patterns

Is plankton biotic or abiotic?
Answer:
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.
