Determine whether the statement is true or false. Suppose P(t) represents the population of bacteria at time t and suppose P'(t)

> 0 and P''(t) < 0; then the population is increasing at time t but at a decreasing rate. True

Answer:

TRUE

Explanation:

If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.

The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.

The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.

When t < 3, P'' > 0.  

When t = 3, P'' = 0.

When t > 3, P'' < 0, because the rate of population growth is slowing down.

Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..

Which type of carbohydrate polymer is used for structural support in the cell wall within plants ?​
anygoal [31]

Answer:

Cellulose is a type of carbohydrate polymer is used for structural support in the cell wall within plants

Explanation:

Cellulose, for example, is a major component of plant cell walls, which are rigid structures that enclose the cells (and help make lettuce and other veggies crunchy). Wood and paper are mostly made of cellulose, and cellulose itself is made up of unbranched chains of glucose monomers linked by 1 4 glycosidic bonds

Describe how each of Newton’s laws may be observable during a car trip.
aleksandrvk [35]
According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Also if a car was going straight but another car (unbalanced force) bumps into it causing the motion of the car to change.

Why is it important to stain youngcultures of bacteria with<br> the grain stain?
uranmaximum [27]

Answer:

Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.

Explanation:

Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.

1. Explain how dehydration synthesis and<br> hydrolysis are related.
PolarNik [594]

<em>Answer: In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.</em>
