Answer:

A

Explanation:

Proteins are large biomolecules produced in living cells. They are polymers made up of monomeric units called amino acids. Asides being structural components as highlighted in the question, complex proteins produced in living cells also serves as biological catalysts that regulates biochemical reactions in the body of living organisms. The protein that perform this function of regulating reactions is called ENZYME.

Catalytic enzymes affects the rate of biochemical reactions, without them, reactions will occur slowly or not at all. Enzymes, which can be anabolic or catabolic depending on whether they catalyze building up or breaking down of complex molecules respectively, are usually specific about what (substrates) they act on.

The amino acids that make up specific enzymes are modified into a three-dimensional shape. This shape determines its function and confers upon it the ability to speed up a reaction. An enzyme gets its name from the type of reaction they catalyze e.g. cellulose synthase catalyzes the synthesis of cellulose from glucose.

Which of the following properties does NOT play a role in trees growing to towering heights by moving water from roots to leaves
jarptica [38.1K]

Answer:

The correct option is;

Water absorbing energy in large amounts to increase energy by a degree of temperature

Explanation:

The growth of trees to towering heights has to do with the formation of plant cell walls which are built by the aggregation Glucose molecules to form Cellulose molecules. The cellulose molecules further combines to form microfibrils by forming hydrogen bonding. The microfibrils that combine to make cell walls

Therefore, the growth of a tree is dependent on the formation of hydrogen bonds between water molecules to enable uptake of water into the plants which enable photosynthetic reaction that result in the formation of glucose

The transpiration, which is the conversion of water into vapor or gas at the leaves facilitates the uptake of more water for the formation of more glucose molecules and creation of hydrogen bonds

The hydrogen bonds between chlorophyll molecules is facilitated by forming hydrogen bond with water molecules.

An outbreak occurs where the first case is detected on October 15th, the last case is detected on October 27th, and the peak is
aksik [14]

Answer:

12-14 october

Explanation:

The probable period of exposure is calculated as follows:

  1. Know  the range of the incubation period
  2. Start counting back from the days of the first case by subtracting the first number of incubation period range
  3. Count back the days from the last case by subtracting the last number of incubation period range.
  4. This will give a range which will be the period of exposure.

From the question,

  • Incubation period range 1-15
  • Date of first case = october 15
  • Therefore, first date of exposure = 15 -1 = 14
  • Date of last case = 22
  • Therefore, last date of exposure = 27 - 15 = 12
  • Thus, the range is 12-14 october which is the probable period of exposure.

The gluten-free diet was originally intended for people with celiac disease, but it’s now become a new fad diet for the general
Aleks [24]

Answer:

The gluten free diet is helpful for the people that are sensitive to food with gluten it which occurs due to the celiac disease. It was originally meant for the such people but it becomes a new fad. However, there is no compelling evidence to support that gluten free diet helps in health improvements n non sensitive people.

In other hand there are majority of doctors are against the use of gluten free diet is not good for various body organs like heart. A study concluded that there are lower risk of heart disease in people take more gluten. Doctors and various study suggests that people with no celiac disease should not avoid gluten.
