Answer: option b) 1 dg
Explanation:
1) These are the different equivalences of those quantities:
a) 1 g = 100 cg ⇒ 1 cg = 0.01 g
b) 1 g = 10 dg ⇒ 1 dg = 0.1 g
c) 1 g = 1000 mg ⇒ 1 mg = 0.001 g
d) 1g = 10⁹ g ⇒ 1 ng = 10 ⁻⁹g
2) Now that you have all the masures in grams you can compare:
0.1g > 0.01g > 0.001g > 10 ⁻⁹g
3) So, the largest value is 0.1g which is 1 dg.
Answer: B.22.4 liters
Explanation:
When we attribute to a certain fixed mass of a given gas a fixed number of molecules. Avogadro considered that the mass of 36g of oxygen at any temperature and pressure would have a fixed number of molecules to which he called 1 mol of molecules. So by definition 1 mole of molecules would have a number of molecules equal to that present in 36 g of oxygen. The occupied volume by one mole of molecules at a given temperature and pressure is called molar volume and consists in 22,4 Liters. The molar volume matches the Avogadro Hypothesis (created in 1811 by Amedeo Avogadro), where equal volumes of different gases, at the same temperature and pressure, have even number of moles.
Each type of electromagnetic radiation and placed in order of increasing photon energy and increasing frequency
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays
This is further explained below.
<h3>What is
electromagnetic radiation?</h3>
Parameters
Frequency =107 100 000 hertz
Wavelength, λ = c / ν => 2.8 m => 2.12 * 10-10 m
Energy = 3.97 * 10 -19 J/ photon.
Generally, the equation for Wavelength is mathematically given as
λ = h c / E
Therefore
λ =6.626 * 10-34 * 3 * 108 / (3.97* 10 -19 J)
λ =5 * 10-7 m
In conclusion, This is considered to be part of the viewable area (green Increasing photon energy from lowest to highest.
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays

Answer:
Pre-zygotic, temporal separation
Explanation:
Reproductive isolation mechanism is of two types:
- Prezygotic mechanism
- Postzygotic mechanism
Prezygotic mechanism isolation occurs before fertilization and helpful in preventing formation of fertile offspring.
In frog external fertilization occurs. In the external fertilization, eggs and sperms are released in water and fertilization occur outside the water.
Prezygotic isolating mechanisms may include behavioral isolation, temporal isolation, mechanical isolation, gametic isolation and habitat isolation.
Temporal separation in reproduction is the sexual activity in the same geographical range but in different periods.
Therefore, the given reproductive isolation is pre-zygotic, temporal separation.
