Answer:
48
Explanation:
Lets assume that the third runner up eats x hot dogs.
The total time for the contest is 15x seconds.
Given is that the winner ate (x+24) hot dogs
The winner's rate of eating is 1 hot dog per 7.5 seconds.
And we know the rate = total time/number of hot dog eaten
We get;
solving we get x= 24
therefore the winner ate 24+24= 48
The correct answer is D.
This was the first manner in which humans adapted to food scarcity, by migrating to new zones and being nomadic, in the constant seek for new lands where they could hunt, fish or collect food.
Later on, they would develop weapons and tools to help them reachs their 'preys' more easily or increase the quantity obtained. The establishment of the first crops meant the transition from the Paleolitic to the Neolitic era, in which human groups started to settle down in a certain territory, to end their nomadic way of life and to substitute it for conducting agricultural and animal husbandry activities.
Hence the options stated described a whole process, but the earliest of all the mechanisms listed was the one detailed in letter D.

Explanation:
The answer is apocrine gland: thermoregulation
Explanation: The gland can be classified into two types: eccrine and apocrine sweat glands. Eccrines are those that release their secretion without loss of the secretory cell cytoplasm. Already the apocrines eliminate secretion with portions of the cytoplasm.
Apocrine sweat glands are less frequent and are located in the armpits, mammary areolas, genital region and perianal region. These glands begin to function at puberty and the secretion varies according to their location and also the action of sex hormones. However, in general, this secretion is more viscous when compared to that eliminated by the eccrine glands. Another point worth mentioning is the fact that the secretion produced by these glands is eliminated in the hair follicle channels, unlike merocrine, which throws on the body surface.
