<span>Using a genetic cross, we can look at the following
A = brown a = White, B = Tall, b = small
With the capital letters being the dominant allele
A a
B AB aB
b Ab ab
The allele we are looking for is Ab which as 1/4 chance
To work out how many are in 2/6 also (1/3)
we do 1/4 x 1/4 x 1/4 = 1/64</span>
The correct option is this: THE MASS OF THE PROBE REMAINS THE SAME, BUT THE WEIGHT OF THE PROBE DECREASES.
The mass of an object is a measure of the amount of substance it contains and this amount always remain the same unless there is a change in quantity of matter. This is the reason why the mass of a substance will remain constant, no matter where it is placed, whether on planet earth or on another planet. The weight of a substance on the other hand is a force, whose value depends on the force of gravity. Thus, the force of gravity that exist in the place, where the object is placed will determine its weight.
A because Only plant cells have chloroplasts
Answer:
1. ionic bonds;
2. salt
Explanation:
Ionic bonding is a case of chemical bond that produces two oppositely charged ions, it occurs where there is the complete transfer of valence electron(s) between atoms. In the case of ionic bonds, the metal loses electrons to become a positively charged cation, and the nonmetal receives the electrons to become a negatively charged anion.
While salt is a mineral that is comprised mainly of sodium chloride (NaCl)
