What are the functions of asteroids?An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.
They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron).
Almost all of the asteroids in our solar system are orbiting in a broad band 19,400,000 miles wide between Jupiter and Mars. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade.

Choose all that apply. Which of the following is true in a comparison of your skin cells to your kidney cells?
1) conduct translation differently
2) contain different DNA
3) contain different chromosome
4) transcribe many different genes
5) conduct replication differently
6) have different transcription factors
7) contain different genes
Answers
Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".
The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.
What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

pairs of chromosomes (or 46 chromosomes) in
all somatic or body cells. These cells divide by
mitosis that forms daughter cells with same
number of chromosome pairs as present in
parent cell.
In humans, gametes (eggs and sperms) are
formed from the germ cells by the process of
meiosis that leads to reduction of chromosomes
in daughter cells (with half the number of
chromosomes as present in parent cell).
Thus, the correct options are:
-bone cell has 46 chromosomes, as bone is a

-Skin cell has 23 chromosome pairs (46

-gamete has half the chromosomes (23

Answers
Answer:
Heredity,Genetics
Explanation:
Heredity is the passing of traits from generation to generation while Genetics is the scientific study of traits being passed from generation to generation.
Traits are the defining characteristics that are passed from generation to generation, and genetics is a branch of science to study heredity.
What is genetics?Genetics is the branch of science to study heredity and evolution, how genes originate and what changes occur over time.
Genes are segments of DNA upon chromosome code for protein, in the genetics gene is the major area of study. How a gene can be transferred from parents to a daughter and lead to heredity can be studied.
Heredity depends on the gene responsible for a particular trait and character, during evolution, there would be changes occur at the genetic level which leads to variation among species.
Therefore heredity is to pass traits, and the scientific study of it is genetics.
