Photosynthesis, which is the process through which some living organisms, including most plants and some fungi, make their own food, produces oxygen as a waste product.<span> The process of photosynthesis in plants is the reverse of the respiration process in humans. While humans breathe in oxygen and expel carbon dioxide, plants ingest carbon dioxide and dispel oxygen.</span>
6-2(4+5)+6
First, you go off of PEMDAS, (parentheses, exponients, mutiply, divide, add, subract), and you will mutiply -2 to the numbers in the parentheses, -2x4 and -2x5. Which will then give you -8 and -10.
Then you set up your equation as normal, except without parentheses, which will make the equation 6-8+-10+6.
Then you will combine the two negative numbers, and it'll give you -18.
Then you will combine both the positive numbers, and that'll give you 12.
Add 12 to -18 and that will give you -6.
Ans.
Sickle-cell disorder is a genetic disorder, which shows defected red blood cells, due to mutation in the genes for hemoglobin protein.
Malaria is common in sub-Saharan Africa region and there, natural selection favored gene for sickle cells, because it might be beneficial to people having sickle cell disease that makes them able to survive in such condition and transmit their genes to offspring.
On the other hand, in those Africans, who moved to United States, where malaria is uncommon or absent, natural selection favored normal, wild type genes, resulting in fewer people with defected sickle cell.
Hence, sub-Saharan African population shows higher percentage of mutated gene for sickle cell as compared to population of United States.
Thus, the evolutionary process behind this difference is 'natural selection.'
Answer:
When living in colder climates, people tend to build their buildings, shops, etc with more insulation and heavier materials so that heat resonates as best as it can in the building.
Explanation:
It is a Chemical reaction taking place un a solution in which one or more of the products is insoluble in the solvent, and so forms solid particles that fall to the bottom of the reactor
