The nucleus of an atom contain protons and neutrons, which make up most of the mass of an atom.

Answer: Option (b) is the correct answer.

Explanation:

In an atom there will always be three sub-atomic particles which are protons, neutrons and electrons.

And, inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.

Protons have a positive charge, neutrons have no charge and electrons have a negative charge.

Mass of these subatomic particles are as follows.

Proton : 1.672623 \times 10^{-27} kg

Neutron : 1.674929 \times 10^{-27} kg

Electron : 9.109390 \times 10^{-27} kg

Thus, we can conclude that out of the given options locations 2 and 3 are likely to have subatomic particles with the greatest mass.

The law of_____
Marta_Voda [28]

Answer:

The correct answer is - segregation.

Explanation:

The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.

The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.

Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease
Gala2k [10]

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.
