Answer:

<h3>A) Enzymes are highly specific protein catalysts</h3>

Explanation:

  1. Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
  2. Enzymes have an active site by which it binds to substrate at that specific site.
  3. Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
  4. Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.

Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for
vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. <u>Action potential. </u>

2. neurons that detect chemicals such as those found in food. <u>Chemoreceptors. </u>

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. <u>Compound eyes. </u>

4. the structure that gives the response to an environmental change.<u> Effector</u>

5. neurons that detect electrical fields. <u>Electroreceptors. </u>

6. secretion of hormones into the blood stream to affect distant processes. <u>Endocrine.</u>

Explanation:  

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

What term is used to describe the nuclear contents during interphase
kolezko [41]

Chromatin is the component that specifies the nuclear contents during inter-phase.

<u>EXPLANATION:</u>

  • The term inter-phase is the type of phase in which the cells would exhibit in all parts of its life.
  • Chromatin is a term used to explains the components and contents of the nuclear in its inter-phase.
  • A cell grows normally and duplicates its internal structure, the DNA, during inter-phase.
  • Then it divides during the phase called mitosis after inter-phase.

How can you tell the difference between a physical and a chemical property? (in your own words)
AleksAgata [21]

Answer:

A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties

A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity
