Organisms can have positive or negative impacts on the ecosystem they live in. The cane toad, or Rhinella marina, was introduced to the Hawaiian Islands in 1932 by sugar cane farmers. Farmers released the toads in their crops to help control pests that were damaging the sugar cane. The cane toad has few natural predators, as it secretes a poisonous toxin from its skin that deters larger organisms from eating it. As a result, the cane toad population thrived and grew to number hundreds of thousands by 1935. width="379" Which role does the cane toad play in the Hawaiian Islands?a. native speciesb. invasive speciesc. uncontrolled speciesd. endangered species

The birth rate is defined as the number of births in a particular time divided by the total population. So the correct option is A.

What is the birth rate?

A total number of births in a specific time (a year) divided by the total population (usually taken as 1000) is called the birthrate. The birth rate is calculated for various reasons.

Some of the things for which birth rate is needed are population count, universal registration of births etc.

Population growth is calculated using birth rate, mortality rate and migration rate from a population. The mid-year population is usually taken as the estimated population.

The birth rate is also referred to as natality. The rate of natural increase is given when the crude death rate is subtracted from the crude birth rate.

The birth rate of a population should be maintained at a moderate level by providing resources to people with children, creating awareness about methods of contraception etc.

The birth rate is calculated by dividing the number of births by the total population.

Therefore the correct option is A.

Answer: Number of half lives occurred 2.

Explanation:

Let the initial concentration be x

Concentration left=25 % of the x= $x(25)/(100)=(x)/(4)$

To calculate the number of half lives, we use the formula:

$a=(a_o)/(2^n)$ ..(1)

where,

a = amount of reactant left after n-half lives = 0.0495 moles

$a_o$ = Initial amount of the reactant = 0.7924 moles

n = number of half lives

$(x)/(4)=(x)/(2^n)$

taking log both sides

$\logx-\log4=\logx-n\log2$

$\log4=n\log2$

$\log(2)^2=2\log2=n\log2$

n = 2

Number of half lives occurred 2.

2 half lives.A half life is when a substance is broken down by half. 100% -> 50% etc.
