In an effort to control vegetation overgrowth, 108 rabbits are released in an isolated area free of predators. After 2 years, it
Elis [28]

Answer:

246

Explanation:

Increased amount / current population = 972

Amount released = 108

time(t) = 2years

Using the exponential growth function :

f(t) = A*g^t

Where g = growth rate

To obtain the growth rate = g

972 = 108 * g^2

g^2 = 972 / 108

g^2 = 9

g = 3

To determine population after 9 months :

9 months to years = (9/12) = 0.75

t = 0.75

f(0.75) = 108*(3^0.75)

f(0.75) = 108 * 2.2795070

f(0.75) = 246.18676

= 246

Which pattern of inheritance results from individual organisms having many different genes working at the same time to control a
saw5 [17]
The answer is polygenic inheritance.
Many physical characters (traits) depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.


For example, the color of the skin in humans. The color of the skin results from the interactions of several factors determined by different pairs of genes:-Certain genes could affect the metabolism of skin melanocytes.-Other genes can determine the distribution of melanin in the thickness of the skin.-Some genes could determine the relative amounts of each of the two possible types of melanin.-Others may affect the production of certain hormones involved in the activity of melanocytes.

the activities in the cell cycle occur during a specific phases. In which phase of the cell cycle is DNA replicated?
ValentinkaMS [17]

Answer:

S phase

Explanation:

The S is short for synthesis, which means that DNA is being replicated.  This is one of the stages of interphase, when the cell is growing and getting ready to divide.  Well, this is the getting ready to divide part of interphase; the cell needs to duplicate its DNA so it has enough to divide out to daughter cells.
