The instructions for making all the proteins are carried by the DNA, these proteins determine one's traits.
The genetic code determines the proteins manufactured by the cell. The proteins refers to the strands of amino acids. The DNA sequence of the genes determines the order of amino acids in a protein. This is the direct association between the traits and the genes.
It is the DNA, which carries all the instructions for the manufacturing of the proteins, these proteins determine the traits. DNA does not possess the tendency to leave the nucleus, thus mRNA copies the message of DNA and carries it to a ribosome. The mRNA is read by the tRNA that brings in the appropriate amino acid to produce the protein. This protein determine a trait.
Thus, DNA sequence determine a trait, as they provide instructions for the manufacturing of the proteins, these proteins further determine a trait.

Answer:The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. This is the direct connection between your genes and your traits. ... Then cellular structures, the ribosomes, translate the RNA into proteins.
Explanation:
b. less water would need to be excreted by the kidneys.
c. they don't have kidneys.
d. their cells would eventually swell.
The best answer is A.
Unlike marine animals such as fish, land vertebrates do not have mechanisms to excrete high salt content. Their excretory organs namely the kidneys are not designed to handle concentrated salt content.
Therefore if high salt content is retained in the body, then osmotic imbalance in cells of land vertebrates would occur with the cells losing water because they would be hypotonic to their immediate surrounding and eventually die.
Marine fish are able to maintain osmotic balance in the sea water because they have specialized cells in their gills that actively eliminate salt and these fishes do not absorb any salt from the water they drink.

By repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
An experiment is defined as a procedure which is carried out to support or disprove a hypothesis. It determines the efficacy or potential of something previously unusable. It provides insight into cause and effect by demonstrating what results when a particular factor is manipulated.
An experiment is defined as a type of empirical study that involves manipulation of an independent variable, measurement of a dependent variable, and control of extraneous variables. This extraneous variable is any variable other than the independent and dependent variables.
The best approach when conducting a scientific experiment is to test repeatedly and make sure the experiment can be repeated.
Thus, by repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).

The right answer are in the picture attached.
Gametes:
A gamete is a sexual cell that allows sexual reproduction. The word gamete comes from elsewhere in ancient Greek and means "spouse".
Gametes function to merge to give birth to a new individual with unique genetic heritage.
The random loss of a chromosome of each pair allows the fertilization of two gametes with each other, whose fusion will give birth to an egg (zygote) endowed, like its parents, with 46 chromosomes.
Meiosis:
* Meiosis consists of two successive cell divisions that will give birth to gametes.
At the end of meiosis, the original cell gave birth to four haploid cells whose genomes were recombined in a unique way.
* In humans, the cells that will participate in meiosis are spermatocytes and oocytes.
* In the cells that will enter into meiosis, the replication of A.D.N. occurred during interphase, each chromosome consists of 2 chromatids connected by their centromere. (Each chromatide is composed of a double-stranded A.D.N molecule and molecules that maintain its structure).
Mitosis:
Mitosis is the process of reproducing (identical) cells.
At the end of the mitosis, the mother cell divided into daughter cells identical to each other and identical to the cell that gave birth to them.
This one can be broken down into 4 phases.
Prophase, Metaphase, Anaphase and Telophase.
Somatic cells:
The set of somatic cells, called soma, are all the cells forming the body of a multicellular organism, that is, all non-germline cells, such as gametes, or cells. germ. These last ones constitute the germen.
Somatic cells are usually the vast majority of cells that make up an individual.
Asexual reproduction (there's no asexual cells in the proposed terms):
A vegetative or asexual cycle, in the context in which this word is used here, means: which does not concern reproduction but which concerns the physiological processes that ensure life, growth, development and multiplication when it is not sexual .
A vegetative or asexual cell is said to be, as opposed to reproductive, a cell whose function is related to nutrition. See the definition of endospore and especially vegetative propagation.
Sexual reproduction (there's no sexual cells in the proposed terms):
Sexual reproduction is a reproductive process that creates a new organism by combining the genetic material of two different sex organisms through a different genital reproductive tract in both males and females. This process occurs in both eukaryotes and prokaryotes; in multicellular eukaryotic organisms, a new individual is created; in prokaryotes, there is scissiparity of the initial cell.
Somatic cells undergo mitosis for growth and form asexual cells. Gametes, produced through meiosis, are reproductive or sexual cells. Mitosis produces identical copies of cells, while meiosis produces gametes for sexual reproduction.
In understanding cell division, we need to look at four main terms: gametes, meiosis, mitosis, and somatic cells. Somatic cells are non-reproductive cells that undergo mitosis for growth and repair, leading to asexual cells, while gametes are reproductive cells (sexual cells) created through meiosis. Mitosis and meiosis are types of cell division. Mitosis divides a cell into two identical copies and is a key mechanism of asexual reproduction. On the other hand, meiosis is involved in sexual reproduction and generates gametes.
