Answer:

Option A, occurs at a constant rate

Explanation:

It becomes easy to determine the age of any radioactive substance when the rate of decay is constant and its starting and presents mass is known.

For example - if we know that the mass of a radioactive substance is 100 Kg few years back , but its present mass is 10 Kg. Then if we know the value of rate of decay, we can easily determine the age of substance based on the logarithmic equation as given below

A_t= A_0*e^{kt}

Where A_t is the mass of radioactive substance at time t

A_0 is the mass of radioactive substance at time t=0

t is the time in years and

k is the decay constant.

Hence, option A is correct.

If pathogen A is more resistant to an erythromycin disc on a Kirby-Bauer plate compared to pathogen B, then pathogen A will have
alexdok [17]

If pathogen A is more resistant to an erythromycin disc on a Kirby-Bauer plate compared to B, then A will have a smaller zone of inhibition compared to B.

<h3>What is the zone of inhibition?</h3>

The zone of inhibition can be defined as a circular region in a plate where pathogenic agents cannot grow.

This zone (zone of inhibition) can determine the action of different drugs like antibiotics for a given disease.

The zone of inhibition test is also widely known as the Kirby-Bauer Test due to their developers.

Answer:

Explanation:

1. a. Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During interphase, the cell copies its DNA in preparation for mitosis.

b. The third phase is anaphase. This phase only takes about 0.8 percent of the cell cycle to complete, which is the shortest time required out of all the phases. During anaphase the sister chromatids, or the two identical parts of a chromosome, are pulled apart to opposite ends of the cell by the spindle fibers.

2. Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.

  • Development and growth. After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. ...
  • Cell replacement. ...
  • Asexual reproduction.
