Answer:A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. These bases are crucially important because the sequencing of them in DNA and RNA is the way information is stored.
Answer:
Type I.
Explanation:
The statistical hypothesis can be used in the scientific experiments to explain any observation or the results. Two main types of hypothesis are null hypothesis or alternate hypothesis.
Sometime error might also be done by the individual while accepting any hypothesis. In Type I error, the individual rejects the correct hypothesis and accept the alternate hypothesis which is wrong. Dr. Mai has also done Type I error in her experiment.
Thus, the answer is Type I.
Answer: Another name for translation is protein synthesis.
Explanation: Translation is a biochemical process in which a messenger RNA (mRNA) molecule is used to make a polypeptide chain (protein). Protein synthesis occurs in the ribosome where the ribosome binds to the mRNA strand and interpretes the codons in the mRNA into their corresponding amino acids. A tRNA brings the appropriate amino acid coded for in each codon and attaches it to the growing polypeptide chain.
The polypeptide chain produced undergoes other processes after translation to form proteins.
Answer:
d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.
Explanation:
The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.
The correct answer is that ammonia is removed from the blood by the liver, which processes it into urea, and discharging it into the circulation.
The liver plays an essential function in the metabolism of proteins. The cells in the liver modify amino acids in foods so that they can be utilized to generate energy, or make fats or carbohydrates.
A toxic component known as ammonia is a waste-product of this procedure. The liver cell transform ammonia to a much less toxic component known a urea, which is discharged into the blood. Urea is then translocated to the kidneys and is removed out of the body in the form of urine.
