Joint movement when you twist head side to side:

Answers

Answer 1

Answer:

The atlantoaxial pivot joint provides side-to-side rotation of the head, while the proximal radioulnar articulation allows for rotation of the radius during pronation and supination of the forearm.

Explanation:

Rotation can be toward the midline of the body, which is referred to as medial rotation, or away from the midline of the body, which is referred to as lateral rotation. Movement of the head from side to side is an example of rotation.

Answers

Inducible and repressible systems are similar in that in both systems the regulatory molecules function by binding to the operator.

An operon is a structural group of genes that are expressed or controlled by a single promoter and is considered the functional unit of genomic DNA.

Similarities between inducible and repressible operons:Inducible and repressible operons are two types of operons in prokaryotic gene organization.Both contain functionally related genes juxtaposed in the genome.Gene regulation of both operons also falls under the general regulatory elements.Moreover, their differential regulation is based on the type of molecular effector that binds to the repressor. When activated, the repressor binds to the promoter-operator region and directs the RNA polymerase to bind to the promoter region

based on their work with insertions and deletions of nucleotides in viral dna, crick and brenner were able to determine that the genetic code is read in increments of nucleotides.

Answers

Crick and Brenner determined that the genetic code was read in increments of three nucleotides.

Why does the genetic code is called triplet?

The same codon cannot code for more than one amino acid and for twenty proteins that are present. If the codons are triplet there will be 64 codons which are used to code for 20 amino acids. Hence, the genetic code is a triplet.

The three major codons are:

UAGUAAUGA

These codons terminate the polypeptide chain. Hence, these are called stop codons.

What is a frameshift mutation?

It is a change in the DNA caused by the insertion or deletion of fragments in a DNA sequence. This affects the reading of the genetic code. If one of the nucleotides is deleted from the sequence, then the entire reading of the sequence is changed.

Hence, Francis crick and Sydney Brenner concluded the order of three nucleotides in DNA through insertion (addition of one or more nucleotides to the DNA) and deletion (removal of at least one nucleotide in a gene).

Androgen hormones are often referred to as “male hormones”. In general, this hormone regulates everything related to the male reproductive organs. However, androgen hormones are also produced in the female body, but the amount is not much in men.

The menstrual cycle begins with the release of menstrual blood (menstruation), which marks the first day of the follicular phase. When the follicular phase begins, estrogen and progesterone levels are low. The ovulatory phase begins with limiting luteinizing hormone and follicle-stimulating hormone levels. During the luteal phase, luteinizing hormone and follicle-stimulating hormone decrease. In this phase, the estrogen level is high. Progesterone and estrogen cause the uterine lining to thicken more, in anticipation of the possibility of conception.

In men, the function of the GnRH hormone is to stimulate the production of LH (Luteinizing Hormone) in the pituitary gland. LH is then carried by the bloodstream, binds to receptors on cells in the testicles, and then stimulates the formation of sperm cells.

The correct option is C : Because they have a phosphate backbone, nucleic acids are sources of phosphorus in food. Nucleic acids include RNA and DNA.

Although "Diets rich in protein and calcium" were suggested as diets that would probably satisfy phosphorus needs, protein and calcium do not contain any phosphorus on their own. Protein-incorporating biological amino acids do not exist.

Many foods naturally contain phosphorus, but dairy, red meat, poultry, shellfish, legumes, and nuts are the largest sources.

They only become visible when cells divide, which is the only time they do.Chromosomes are found in all living things, and humans have 23 pairs of them. These 22 pairs of chromosomes are known as autosomes, and both males and females have the same number of them. Allosomes, or the 23rd pair of chromosomes, are unique to each gender. Males only have one copy of each of the "X" and "Y" chromosomes, whereas females have two copies of each.
