this population?
A. 300 - 1000 = 0.3
B. 1000 + 300 = 1300
C. 1000 x 0.3 = 300
D. 1000 - 300 = 3.33
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.
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:
New cells produced within uterus (or any other organ) as a direct result of mitotic cell division.
Mitosis is the type of cell division which results in the formation of two daughter cells with same number of chromosomes as that of parent cell. It plays an important role in growth and repair of cells and tissues in multi-cellular organisms such as human beings.
For example, mitotic division helps in formation and repair of uterus lining lost during menstrual phase. Similarly, it keeps replacing the dead skin cells lost from our body surface on regular basis.
Meiotic division on other hand is used only in the formation of haploid gametes i.e. sperm in males and egg in females.
Answer:
Everything living would die
Answer:
Without DNA, cells could not reproduce, which would mean extinction of the species. Normally, the nucleus makes copies of chromosomal DNA, then segments of DNA recombine, and next the chromosomes divide twice, forming four haploid egg or sperm cells.
