Solar flares occur constantly, and would have to be HUGE to impact the Earth's climate (remember, climate is measured over long periods of time). While solar flares do affect weather and other things, such as radio waves, they don't affect climate. So C is out. Variations in Earth's orbit are short-lived, so A is out. Earth's reflectivity would need to change in order to contribute to climate change, so ignore answer B.
Now let's look at D and E. Ocean circulation is one of the most important factors affecting Earth's climate, and the primary factor leading to changes in ocean circulation is plate tectonics, or, more specifically, continental drift due to plate tectonics. Plate tectonics cause continental drift, which changes ocean currents, which leads to ice ages, ice cap melting, and global climate change. D and E are correct.
Bacteria can cause many infections such as pneumonia, wound infections, bloodstream infections, and also STD's.
Answer:
It is easier to send the raw materials to the factories to become finished goods.
Explanation:
I don't know if this was multiple choice, but you would put the farmland upstream from the factories so that the crops and other raw materials could easily go down to the factories to be finished. I hope this helped :)
Protista:
This is a kingdom that compromises mostly single-celled organisms (such as: Protazoa)
Answer:
C.) 26 - 13
Explanation:
During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.
DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.
