Apopulation of deer has a per capita rate of increase of 0.1 deer per year. if there are initially 300 deer in the population, and the population is growing exponentially, how many deer will be in the population after 1 year?

a) 30
b) 300
c) 330
d) 600

c) 330

Explanation:

Formula to calculate exponential growth is written as:  

                 y = a( 1+r)ⁿ

a = initial quantity  

r = growth rate as a decimal

n = number of time intervals  

y = quantity after n time

As per the question given  

a = 300

r = 0.1  

n = 1 year

y = ?

Thus,

y = a( 1+r)ⁿ    

300(1+0.1)¹

300 × 1.1 = 330

Therefore,

y = 330

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
