Answer:
Metaphase
Explanation:
During metaphase, the chromosomes line up along the center axis of the cell, called the metaphase plate, and attach to the spindle fibers. Since the chromosomes have already duplicated, they are called sister chromatids.

How did Kepler develop his second law of motion?(1 point)
a He made accurate measurements of the positions of all the planets over many years.
b He used a telescope to carefully follow and time the orbital motion of Mars.
c He compared data of planetary motion at different times along orbits.
d He invented a telescope that was strong enough to view all planets of the solar system along their orbits.
Answer:
He found that the planets do not all move at the same speed. (A)
Explanation:
Kepler develop his second law of motion by he made accurate measurements of the positions of all the planets over many years. So, the correct option is A.
What do you mean by Kepler's second law?Kepler's second law states that a planet moves in its ellipse so that the line between it and the Sun placed at a focus sweeps out equal areas in equal times.
This discovery by Kepler gives the idea of the planetary motion of all planets. According to this law, the planets moved on a circular path around the sun, but the speed of revolution is different for each planet.
Therefore, Kepler develop his second law of motion by he made accurate measurements of the positions of all the planets over many years.

a sample of dna contains 10% guanine. what is the percentage of the remaining nitrogenous bases?
Answer:
10% 40% 40%
Cytosine 10%, Thymine 40% and Adenine 40%
If the sample of DNA contains 10% guanine, the percentage of remaining nitrogenous bases are cytosine 10%, adenine 40%, and thymine 40%.
What is a Nitrogenous base?
A nitrogenous base may be defined as the nitrogenous compounds that form an important part of the nucleotides which are known as the building blocks of nucleic acids like DNA or RNA.
According to the question,
The concentration of guanine in DNA = 10%.
According to Chargaff's rule, the amount of guanine is equal to the amount of cytosine. So, the concentration of cytosine is also 10%.
Now, the remaining amount of nitrogenous base = 100-20 = 80%. This 80% is divided into adenine and thymine 40% each.
Therefore, the percentage of remaining nitrogenous bases are cytosine 10%, adenine 40%, and thymine 40%.

Sexual reproduction is the most common form of reproduction in the animal kingdom and is the only reproduction type in humans.
With over seven billion humans on Earth, there is an enormous variation in genetics within the human population. Which
statements describe how cell division and sexual reproduction contribute to this huge genetic variation? Select ALL that apply.
A)
B)
Random fertilization of haploid eggs by many potential haploid sperm
increases genetic variation
Increased frequency of mitotic division ensures that animals have cells to
replace those that are lost.
The ability of homologous chromosomes to swap and exchange gene
regions in meiosis contributes to genetic variation.
Random assortment of homologous chromosomes in metaphase I increases
the variation of chromosomes that segregate into gamete cells in meiosis.
Increased chromosome number at the end of meiosis ensures that resulting
offspring have additional chromosomes containing increased genetic
variation
D)
E)
The statements that describe how cell division and sexual reproduction contribute to huge genetic variation is as follows:
The ability of homologous chromosomes to swap and exchange gene regions in meiosis contributes to genetic variation.Random assortment of homologous chromosomes in metaphase I increases the variation of chromosomes that segregate into gamete cells in meiosisRandom fertilization of haploid eggs by many potential haploid sperm increases genetic variationSEXUAL REPRODUCTION:
Sexual reproduction is the kind of reproduction that involves two organisms (male and female). Sexually reproducing organisms produce gametes or sex cells by a process called MEIOSIS. Meiosis reduces the chromosome number by half i.e. from diploid (2n) to haploid (n). A process called crossing over, which is the process by which non-sister chromatids of homologous chromosomes exchange their genetic material. The process of crossing over aids in genetic variation.The statements that describe how cell division and sexual reproduction contribute to huge genetic variation is as follows:

Answer:
1. Random fertilization of haploid eggs by many potential haploid sperm increases genetic variation.
2. Random assortment of homologous chromosomes in metaphase I increases the variation of chromosomes that segregate into gamete cells in meiosis.
3. The ability of homologous chromosomes to swap and exchange gene regions in meiosis contributes to genetic variation.
Explanation:
Meiosis has crossing over in prophase I which increases genetic variation, independent assortment in metaphase I, and resulting haploid cells by the end. The resulting haploid cells can fertilize other haploid cells, with a random nature. However, mitosis does not contribute to genetic variation. Also, meiosis results in haploid cells, not diploid cells or cells with an increase in genetic chromosome quantity.
