As stated on google it says “ Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce. ... This is evolution through artificial selection.”
Answer:
Archaea
Explanation:
Archaea are prokaryotic single cell microorganism.
They are usually found in extreme environment like hot thermal vent and others. They share characteristics with bacteria and eukaryote. Archaea as a prokaryotic organism they lack true nucleus and organelles but unlike bacteria they are unaffected by antibiotics and contain different cell wall components. Unlike bacteria and eukaryotes, their membranes contain branching lipids.
Answer:
im guessing it's the second one
Answer:
0.93 mol
Explanation:
Given data:
Number of moles of Na atom = ?
Number of atoms = 5.60× 10²³
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
5.60× 10²³ atoms × 1 mol / 6.022 × 10²³ atoms
0.93 mol
There are a couple of ways in which you can express the concentration of a solution, and here they are: gram per liter (g/L), molarity (M), parts per million (ppm.), and percents (%).
As you can see, only M appears in your answers, which means that the correct option should be (2) 3.5 M.
