Explain how competition for food can cause natural selection.​

Answers

Answer 1

Answer:

Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.

For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

Answer:

we must look at billions of years

When considering the entire period of time during which life on Earth has been evolving, we must look at: D. billions of years.

Evolution can be defined as a process of gradual change in the characteristics of various species of living organism over several generations.

Basically, these characteristics refer to gene expressions that are typically transferred from parent organisms to their offspring or successive generations.

The earliest life forms known to humans existed about 3.7 billion years ago and they are microscopic organisms (microbes) whose fossils were found on rocks.

In conclusion, when you are considering the entire period of time during which life on Earth has been evolving, you must look at billions of years.

2. D. It determines the hotness or coldness of an object.

3. D. Energy transferred due to temperature differences.

4. C. The object is a thermal insulator.  

Explanation:

Convection is the transfer of heat energy through the movement of a liquid or gas from one place to another. If we place a metal object at a distance from the hot body so the fumes that comes out increase the temperature of the metal that is present on the hot body. Temperature determines the hotness or coldness of an object not the heat. The heat energy transferred from one body to another due to difference in temperature of both objects. Insulator are those materials which no ability to transfer heat energy from one place to another.

The water balance is the relation or balance between the amount of water entering the organism by intake liquids and food and the total output or loss of water lost from the body by different ways such as the kidneys, lungs, bowels, and skin.

Other than water there is the constant input of electrolytes also occurs into the system. Osmotic pressure and the process of osmosis help in ensuring that optimal concentrations of electrolytes and non-electrolytes are maintained in the cells. The excess water or electrolytes, move out of the cells by the osmosis through the semi-permeable membrane that is the cell membrane here.
