Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
Answer:
In the result of meiosis, testes produce 4 small mature sperm while ovaries produce 1 large egg cell.
Explanation:
Meiosis produces gametes (sex cells). Sex cells are eggs in females and sperm in males.
In the female, ovaries produce four haploids (3 polar bodies and 1 immature egg) under meiotic division. Polar bodies die because of the unequal division of cytoplasm. The immature egg matures into a large ovum/egg every 28 days during the menstrual cycle that is able to fertilize.
In the male, meiosis occurs in testes that produce 4 spermatids that mature into 4 small sperms. Testes produce several hundred million sperms every day under meiosis. These sperms are able to fertilize.
Nevertheless, if we want to compare their numbers based on meiotic division, we would say that they will be in the same ratio (1:1) at the end of each meiosis cycle for males and females.
Answer: the actual size of the population is relatively small.
Explanation:
In relatively small populations, the phenomenon of genetic drift significantly may change the frequencies of the alleles in that population. This consequently affect the genetic structure of the population in context.
Whereas big populations doesn't significantly feel the shakings of this phenomenon because her effects are small and insignificant.
1 pound = 0.45 kg
Therefore
18 pounds = 18 x 0.45 = 8.1 Kg
But, the dosage is 5 mg per kilogram of the body.
Thus,
5 mg for each of the kg will be
5 x 8.1 = 40.5 mg
Therefore, 40.5 mg Ibuprofen for 18 pounds body weight
I think the answer is D. Circulatory because this system helps to get the absorbed nutrients throughout the whole body
