Answer:
By their chemical composition
By their asthenospheres
Explanation:
The earth's layers can be defined with the help of the following facts:
By their chemical compositions. By their physical properties.Thus, the correct options for this question are A and B.
What are the different layers of the earth?The structure of the earth is generally categorized into four major layers. They are as follows:
The crust.The mantle.The outer core.The inner core.Each of the above-mentioned layers has unique chemical composition. Apart from chemical composition, the physical state is also important when describing the different layers of the earth. The concentration of iron is found to be the highest in the core regions along with a little bit of nickel.
Therefore, chemical composition and physical properties are the two parameters that are used to define the different layers of the earth. Thus, the correct options for this question are A and B.

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

E)

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.

What is blood group?Mother has the blood types A, B, AB, and O. The child has the blood types A, AB, B, and O. The fluid termed plasma, which is the blood, contains the red, white, and platelet blood cells.
Four main blood types are distinguished by the ABO system:
Blood group O has both anti-A and anti-B antibodies in the plasma but no antigens. A and B antigens are present in blood group AB, however there are no antibodies. Red blood cells with blood group A antigens have anti-B antibodies in their plasma. B antigens and anti-A antibodiesTherefore, Red blood cells, white blood cells, and platelets are contained in a fluid called plasma, which is the blood. The blood group of father will be A, A, AB, O.

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%.
