A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y
antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:  

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:  

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.

How are the cells in multicellular organisms different from those in single-celled organisms?
Mrac [35]

Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.

Explanation:

Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc

From the examples given, the cells of multicellular organisms are specialized in function in that:

- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces

On the other hand, unicellular organisms possess just one cell that do all the functions.

Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.

Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level<span>, </span>primary producers<span> (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present, they represent still higher trophic levels. Organisms that feed at several trophic levels (for example, grizzly bears that eat berries and salmon) are classified at the highest of the trophic levels at which they feed. Decomposers, which include bacteria, fungi, molds, worms, and insects, break down wastes and dead organisms and return nutrients to the soil
