Surface currents are different from deep ocean currents because surface currents depend on the temperature, pressure, wind, and moon to determine them but deep water currents are too deep for any of that to affect them and are generally always there
***They both move from the Northern hemisphere to the southern hemisphere
The conclusion for this particular observation would be that one of the finches has food sources on both islands, thus lives on both of them, while the other finch has food sources only one of the islands, thus lives on that island. The food sources about which the finches, or any other organisms, have specialized, determines where they can be found. If there is sufficient amount of the food source to support a population, then the species can and will probably live there, but if there isn't then the species can not, and will not live there.
The right answer is; This is important for laboratory safety.
Before using any chemical in the lab, one should first read the Material Safety Data Sheet (MSDS) because it is important for laboratory safety.
A Material Safety Data Sheet (MSDS) is a technical document that contains detailed information about the protective measures to take, and the possible hazards of a chemical. The Material Safety Data Sheet (MSDS) is available for all the chemicals used in the laboratory and it may be written, printed or electronic.
The answer should be C, progesterone.
Progesterone is the hormone which can help maintain the lining of uterus and to further thicken it so that the uterus is prepared for implantation and the development of a baby. The level of progesterone is significantly rose after ovulation.
On the other hand, LH, luteinising hormone, is produced by oestrogen, another female hormone which will drop after ovulation. LH helps stimulate ovulation and prevent the development of other follicles, the origin of eggs, to form yellow body instead. Which yellow body is the one which stimulates the production of progesterone.
Last but not least, I believe D should be testosterone, and it is a male hormone so it will not be found in female normally.
Therefore, your answer should be C, progesterone.
