Feliz [49]

Answer:

Vagina

Ovary (Pl. Ovaries)

Uterus

Explanation:

The vagina is also called the birth canal. It is a hollow, muscular tube attached at the lower end of the uterus and opens to the outside. It is called the birth canal because this is where the baby passes from the uterus to the outside world.

Ovaries are oval-shaped organs where egg cells are developed. They are located at the sides of the uterus, attached to the fallopian tubes. It is also the site of estrogen production which is also known as the female sex hormone.

Uterus is also known as the womb. This is a pear-shaped organ where the fetus will grow if an egg cell is successfully fertilized by the sperm cell. The main body of the uterus called the corpus and it is expandable, which makes it capable to hold a growing fetus.

Progressive muscle relaxation suggests that tension and relaxation are not mutually exclusive.

Te answer is False.  T<span>ension and relaxation are mutually exclusive--it is not possible to be relaxed and tense at the same time.  R</span>elaxation of the body through decreased muscle tensions will, in turn, decrease mental tension.  It is <span>Edmund Jacobson's who showed us Progressive Relaxation Technique.</span>

2. Protein A has a binding site for ligand X with a Kd of 10-6M. Protein B has a binding site for ligand X with a Kd of 10-9M. W
allsm [11]

Answer:

Protein B has a higher affinity for ligand C than protein A

Explanation:

Binding affinity is a measure of the strength of the bonds or interactions between a single biomolecule or receptor to its ligand. A ligand is usually a small molecule that binds to a specific receptor.

The receptor is usually a large molecule that contains a specific site for the binding of ligand.

Binding affinity is usually measured by the equilibrium dissociation constant (KD). The equilibrium dissociation constant KD is a ratio of the dissociation and the association of ligand to the receptor. The value of KD is used to evaluate and compare the strengths of bimolecular interactions.  The larger the KD value, the more weakly the target molecule and ligand are attracted to and bind to one another.

The higher the dissociation constant (KD), the weaker the affinity is between the interacting molecules, whereas, the smaller the KD value, the greater the binding affinity of the ligand for its target.

Protein B has a KD value of 10⁻⁹ M while Protein A has a KD of 10⁻⁶ M.

Ration of KD of protein B to protein A = 10⁻⁹ M/10⁻⁶ M = 10⁻³

Therefore, protein B has a KD value which is 1000 times smaller than the KD of protein A.
