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.
"50" percent of the offspring will be pink is the one among the following choices given in the question that will happen if <span>a red rose is crossed with a pink rose. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer has helped you.</span>
Answer:
As the population increases, the food supply, or the supply of another necessary resource, may decrease
Explanation:
Yes it can kill brain cells. if you hold your breath for a short amount of time example 10 seconds it won't do any harm. but if you hold your breath for an extended time like a minute the cells will not get enough oxygen and eventually die. I hope I helped you
Answer:
<h2>Have a common understanding in the classification of organisms</h2>
Explanation:
- Taxonomy plays an important role in the classification of organisms to study the organisms on the basis of their properties.
- Taxonomy is a branch of biological science that explains the identification, characterization, naming and classification of the organisms thus it is helpful to understand the different types of organisms that are present in the biosphere.
- Taxonomy makes the scientist come on one point about the unknown organisms according to morphology, anatomy, physiology and some other properties of the organisms.
- Thus a common understanding is generated among scientists of the world.
