Answer: c. molecular structure of DNA
Answer:
In secondary succession, a previously occupied area is re-colonized following a disturbance that kills much or all of its community. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill animals unable to flee the area.
Answer:
<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>
Explanation:
The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.
Answer: population increases by 15
Explanation:
The population growth will be calculated by adding the Natural Increase in population plus the Net In-Migration. This will be:
Natural increase = Birth - Death rate
= 35 - 7
= 28
Net-In-Migration = Immigration - Emigration
= 4 - 17
= -13
Therefore, population growth will be:
= 28 - 13
= 15
Therefore, population increases by 15
