How are plants pollinated?
matrenka [14]

Answer:

People can transfer pollen from one flower to another, but most plants are pollinated without any help from people. Usually plants rely on animals or the wind to pollinate them. When animals such as bees, butterflies, moths, flies, and hummingbirds pollinate plants, it's accidental. hope that helps love!!

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.

Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of kno
xenn [34]

Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is :  The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test <u>color, malleability, melting points</u>, and to test how shiny or dull it is. I would propose these to increase the <em>certainty</em> in the identity of the metals.  Btw, please mark me brainliest.

Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".

The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
