Answer:
So, they do eat...they do reproduce...they are simple...and can move.
So if you were lazy and skipped a type of food mentioned or anything, please ask the entire question, with all the included words. This way I can evaluate from how/the way they say it.
Answer:
Explanation:
His conclusion is correct. We are overpopulated. Our planet cannot stand double the population it currently has. Waste for one thing is an unsolvable problem with 14 billion people on the planet. We are already in massive trouble with 7 billion.
But the moral principle involved is not correct. Laws have been set up that prevents us from killing each other off. Holocausts have solved nothing but that we are capable of mass murder. The population problem and all it's side effects have not been eradicated.
The Bible records God's attempt at doing what Thanos wanted to do. He saw immediately after the flood that was not the answer. Too many people is one thing. Murdering half is no answer that will work.
The given is incomplete as the options are missing. The correct options for the given question are as follows-
(A) cultivation of agricultural land inhibits the decomposition of organic matter
(B) nitrogen-fixing bacteria are not as plentiful in agricultural soils because of the use of pesticides
(C) land that is available for agriculture tends to be nutrient-poor
(D) the nutrients that become the biomass of plants are not cycled back to the soil on lands where they are harvested
Answer:
Option (D)
Explanation:
In order to carry out agricultural practices, the soil must be rich in essential nutrients for the growth of crops. The soil fertility is a key role in the production of crops.
This agricultural land often requires a large amount of these nutrients and minerals because some of the nutrient minerals are converted into plant biomass which is then used up to produce energy in other sectors. So, the nutrients that were present in the soil are taken away and not transferred back into the soil. This means that the nutrient cycle gets affected. Due to this reason, there requires a constant supply of nutrients into the agricultural fields.
Thus, the correct answer is option (D).
Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.
Answer:
1) Oxygen, sugar, water and carbon dioxide are the main starting material and products of both photosynthesis and cellular respiration.
2) The diagram shows that cellular respiration which requires oxygen and sugar is the opposite of photosynthesis which requires water and carbon dioxide. The products of cellular respiration are the starting materials or photosynthesis and the products of photosynthesis are the starting materials for cellular respiration.
