Alcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH3OH) into nontoxic substances. Methy
KonstantinChe [14]

Answer:

D.Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Methyl alcohol is a competitive inhibitor of ethyl alcohol. This means that both of them compete with each other for the same enzyme (ADH). Methyl alcohol leads to poisoning because it is converted to toxic formaldehyde in body. It can be treated by increasing the concentration of ethyl alcohol.

More ethyl alcohol (substrate) will reduce the competitive inhibition by methyl alcohol (inhibitor). This will happen because a substrate needs active sites on an enzyme to attach to it. If ethyl alcohol is increased in concentration, it will occupy more active sites and their availability to methyl alcohol will be reduced. Thus, the enzyme will not be able to act on methyl alcohol.

1 Identify the hormones (and their functions) of the hypothalamus and the anterior and posterior pituitary glands in homeostasis
Valentin [98]

1.The hormones of the hypothalamus and the anterior and posterior pituitary gland are antidiuretic hormone and oxytocin and ADH.

<h3>What hormones are produced by the hypothalamus and their functions?</h3>

The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.

2. The endocrine glands on models  are :

  • hypothalamus.
  • Hypophysis.
  • Thyroid gland.
  • Parathyroid glands.
  • Islet cells of the pancreas.
  • Adrenal glands.
  • Testicles in men and ovaries in women.

<h3>What are the general characteristics of the endocrine glands?</h3>

The main feature of endocrine glands is the absence of excretory ducts. The service product produced by endocrine cells is transported to the extra diffusion space, reaching the interior of blood vessels.

3. When an imbalance of the endocrine system occurs, it results in Hormonal disorders can be caused by various factors such as diabetes, psychological changes, stress, eating disorders, regular use of medication and cancer.

________________ is the ability of a microscope or camera lens to separate what to the unaided eye appears to be one object into
lyudmila [28]

Answer:

Resolution.

Explanation:

This is the ability to  distinguish between two separate  points.  if two  separate points can not be seen separately, but as a single  point,  they can not be resolved.   Consequently Resolution  is the amount of  details of an object that that can be seen. Thus the more  the  higher  the resolution of an object the more  the detail of the object that can be seen.

For example the maxiimum reso;ution of  light microsope is 20nm<u>. Therefore if two objects are placed together more than 20nm apart , they can not be seen(resolved); that is  distinguished from one another by light microscope,This is the limImitation of light microcope.</u>

Electron microscope makes use of beam of electrons for focusing, therefore has resolution than light microscope
