Answer:
c haploid gamete cells
Explanation:
The vast majority of cells in the body are diploid, meaning they have two copies of every chromosome. However, like the question says, if during fertilization, the diploid cells fuse, then there will be 4x copies of every chromosome in the first generation, 8 in the second, and so on.
Meiosis creates haploid cells from diploid cells through one round of DNA replication and then two cell divisions to create haploid cells, one copy of each chromosome.
During fertilisation, when the gametes fuse, they make a diploid cell that develops into a new organism.

Which cell structure is found in plant cells, but not in animal cells?
(1) cell wall
(3) nucleus
(2) cell membrane
(4) cytoplasm
Answer:
(1) Cell Wall
Explanation:
Plant cells have a cell wall, animal cells do not. This causes plant cells to have a structured shape, while the animal cell shape can vary.
A red blood cell is placed into a sugar water solution. The red blood cell has a lower concentration of protein and sugar than the outside solution, as shown in the diagram. In the diagram, the volume of the cell is equal to the volume outside the cell. Protein and sugar are both too big to move through this cell's membrane.
Becuase the cell has a lower concentration that the solution it is placed in, the solution is considered hypertonic. The cell will lose water through osmosis and will shrink, the 2nd option is correct.
The most likely thing to occur when a red blood cell is placed in a sugar water solution is:
B. Water from the red blood cells will diffuse into the solutionAccording to the given question and diagram, we can see that a red blood cell is placed in a sugar water solution and the volume od the cell is equals to the volume outside the cell which shows that equilibrium has been attained.
As a result of this, this solution is hypertonic because the cell has a lesser concentration than the solution as the red blood cell contains less protein which would make the cell to lose water through osmosis as the cell walls would shrink.
Therefore, the correct answer is option B

John and Marianna are expecting their first baby. John has a widow's peak (dominant allele) hairline
while Marianna has a straight hairline (recessive allele). If they have a daughter, she will have a
widow's peak, not a hairline that is indeterminate or a mix between a widow's peak and a straight
line. Why is this so?
Answer:
its due to law of dominant
only dominant character is ecposed in 1st generation
If they have a daughter, she will have a widow's peak, not a hairline that is indeterminate or a mix between a widow's peak and a straight line. This happens due to law of dominance.
What is law of dominance?Law of dominance was given by Mendel and according to law of dominance parents with pure, and contrasting characters are crossed with each other, than in this condition only one form of character appears in the coming generation.
DNA has also known as Deoxyribonucleic acid it has been basically composed of two polynucleotide chains and by nature it has a polymer. The polynucleotide chains folded around each other to form a coiled or structure which is double helical and it has been consist of genetic material along with genetic information which has very much essential for proper body functioning, reproduction, growth, and other necessary activity of the body.
Therefore, If they have a daughter, she will have a widow's peak, not a hairline that is indeterminate or a mix between a widow's peak and a straight line. This happens due to law of dominance.

How would gravity cause planets to move if they had no inertia
Answer
[tex]--------------------------------------------[/tex]
According to Answers, Inertia is defined by Newton's first law,
"Objects in motion stay in motion, objects at rest stay at rest"
If a planet had no inertia it could come to a stop or accelerate to high speeds without any force applied to it. It also would not find an orbit.
Inertia is a fundamental property of the law of conservation of energy.
Without it, the planet, and the universe would be quite, quite different.
