Answer:
A. Water molecules have strong intermolecular attractions.
Explanation:
Water molecules have strong intermolecular attractions due to the presence of hydrogen bond between oxygen and hydrogen atoms. This hydrogen bond is present between hydrogen of one water molecule to the oxygen of another water molecule. This hydrogen bond is weaker than covalent bond so that's why it can be broken down and water is converted into vapours form by heating.
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate would result in decrease in population showing negative population growth.
Explanation:
Negtaive population growth is a term used when individuals leaving the population is more than new individuals in the population.
Individuals would leave the population by two means:
either they die or emigrate from other places to join in.
The following scenario will be analysed by the formula provided to know the negative growth in population:
population growth = (birth rate + immigration) - (death rate + emigration)
putting the values in the equation:
first case:
immigrated individual = 14
emigrants = 0
new born = 14
died = 14
population growth = (14+14)-(14-0)= 14
second case:
immigrants = 28
emigrants = 40
new born = 10
died = 0
population growth= (10+28)-(0+40)= - 2
third case:
immigrants = 0
emigrants = 12
new born = 17
died = 5
population growth = (17 +0)-(5+12) = 0
fourth case:
immigrants = 0
emigrants = 19
new born = 25
died = 4
population growth:(25+0) - (19+4) =3
In second case the population growth has become negative. The value of population growth is -2.
D. The largest population that can be supported
D, since a capsids protects a viruses and it acts as a shell like material, if a drug that damages the capsids would make the virus be able to be killed off because it does not have its protection anymore.
