Explanation:
the genotype of the mother is X⁻X
the genotype of the father is XY
the gametes from the mother are X⁻ andX

Which of the following cell processes is NOT considered a type of asexual reproduction?
A. meiosis
B. fragmentation
C. binary fission
Answer: A - Meiosis
Explanation: Asexual reproduction always results in daughter cells that are identical to the parent cells. In Meiosis, the daughter cells have half of the number of chromosomes of the parent cells. Meiosis is used in sexual reproduction, while fragmentation and binary fission are used by asexual organisms.
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.

there are 30 sodium ions found outside the cell and 10 inside the cell. if the cell is utilizing active transport to move these molecules, where will the sodium ions travel?
I NEED AN ANSWER ASAP!!!
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).

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.
Answer: Plankton is biotic

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

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.

Answer:D
Explanation:
Multiple Sclerosis is an autoimmune disorder. Therefore, option (D) is correct.
What is multiple sclerosis?Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system. It occurs when the immune system mistakenly attacks and damages the myelin sheath, the protective covering of nerve fibers in the brain and spinal cord.
This leads to a range of symptoms that can vary greatly from person to person, including fatigue, vision problems, numbness, muscle weakness, and difficulty with coordination and balance.
The cause of MS is not yet fully understood, but it is believed to involve a combination of genetic and environmental factors. There is currently no cure for MS, but treatments are available to manage symptoms, slow the progression of the disease, and improve quality of life for those affected.

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.
