<h2>Rates of Population Growth</h2>

Explanation:

  • <em>Growth is precisely defined for microbes as increment in number of cells, not size</em>
  • Development rate is change in cell numbers per unit time. Age time is the time it takes for a cell to double. Also called doubling time.
  • Development rates allude to the rate change of a particular variable inside a particular time span and given a specific setting.  
  • r = (births-passings)/populace size or to get in rate terms, <em>simply increase by 100</em>
  • The populace is so a lot greater, a lot more people are included. In the event that a populace develops by a consistent rate for every year, this inevitably indicates what we call exponential growth..

7. Why is approximately 50% of any individual's DNA inherited from that individual's father?
Strike441 [17]

Answer:

B. It was passed to the individual by a gamete from the father.

Explanation:

<u>DNA is transferred</u> to the next generation <u>via gametes</u>, which are produced during <u>meiosis</u>. During meiosis, <u>half of the genetic material</u> is <u>transferred</u> from parent cell to their gametes. Therefore, among the given options, only <u>B is correct</u>.

Option A is not correct because it talks about <u>somatic cells;</u> whereas, in somatic cells, <u>genetic material is not transferred half</u> rather duplicate first and then a complete duplicated set of genetic material is transferred.

Option C is also not correct because only <u>one gamete (sperm)</u> fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.

A 2550 gram box is pushed across the floor with a net force of 18 .0 N.
Aleks04 [339]

Answer:

The acceleration of the box across the floor is 7.0588 m/s^2

Explanation:

Given:

Mass of the box =  2550 gram

net force  acting on the box   =  18 .0 N.

To Find:

The acceleration of the box across the floor = ?

Solution:

Newton's 2nd Law of Motion states that the acceleration of an object as produced by a net force is "directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. "

Newton's Second Law formula is

F = m a

Where:

 F = the magnitude of the net force, in N

 m = the mass of the object, in Kilogram

 a = the acceleration of the object, in m/s^2

Now substituting the values, we get

18.0 =  a (2.55)     [since 2550 gram = 2.55 kg]

a = \frac{18.0}{2.55}

a =  7.0588 m/s^2
