A. How do the Earth’s physical factors influence population density? When population growth increases in an area, what is happen
madreJ [45]

Question 1 The world's population is spread very unevenly. Some spaces are empty or very sparsely populated: we speak of human deserts:

• Cold polar environments are the least populated regions: the ground, frozen permanently, prevents any form of agriculture, the very low temperatures make the habitat difficult.

• The hot or cold desert environments are also not busy: the lack of rain and the strong heat during the day limit the activities of men. The only exceptions are oases.

• The role of relief is more difficult to define. High temperate mountains like the Alps are generally sparsely populated but tropical chains like the Andes have a high population density. However, men have generally settled in the plains, in the valleys (along with the rivers) and on the coasts.

There are also other factors unrelated to land factors that influence population density such as job availability, or even historical factors.

Question 2: Birth rate:

The birth rate (sometimes called the crude birth rate) is the ratio of the annual number of births to the average total population for that year. When the population grows, the contact between people will be more permanent, and it will increase the marriage rate, and thus the birth rate. Age structure:The age structure is a mode of graphical representation of the structure (of age as well as of sex) of a population which constitutes a synthetic image of the past, present and future of the population.When a population resides for a long time in the same place (in favorable conditions, not raising the death rate and without moving), this will vary the age structure by observing an increase in the elderly population.

Which statement accurately describes an aspect of human reproduction
Nitella [24]

Ans.

Human reproduction involves release of sperm (male gamete) and egg (female gamete) and their fusion to form zygote that develops into embryo. In females,  an egg is released each month as a part of a monthly cylce, called menstrual cycle. The  release of egg is termed as ovulation, in which tiny eggs are send into the fallopian tubes for fertilization.

Hence, the correct answer is 'a). an adult female usually releases an egg from an ovary each month.'
