Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
The answer is A- sperm and egg. gametes are reproductive cells in mammals, so sperm and egg would be the correct.

<u>Given:</u>
Present population of bison = 3652
Maximum growth rate = 0.28
<u>To find:</u>
The population of bison after one year.
<u>Solution:</u>
The future population can be calculated with the help of the following formula,

where
is the future population,
is the present population, r is the growth rate and n is the number of years.
On substituting the given values in the formula we get,


Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
Answer:
Only cells contain cytoplasm
Explanation:
Viruses are microscopic creatures (not alive though), that can use genetic material such as RNA or DNA, just like cells.
About protective covering, viruses use a capsule to protect this genetic materials, while cells use the cell membrane and the cell wall (like plants and some bacteria).
