Answer:
The given statement is true.
Explanation:
In the nuclei atoms we know that there are 2 type of particles named protons and neutrons.As we know that the neutrons are uncharged and protons are positively charged thus in such a close proximity when the proton's are just touching each other the electrostatic forces of repulsion between the particles becomes exceedingly large thus rendering the nucleus theoretically unstable. But as we know that the nucleus is inherently stable indicating that there is another type of force that must act between the nucleons (proton's and neutrons) this fundamental force is known as strong nuclear force and is the strongest force among the 4 fundamental forces in nature.
Answer:
Tall offsprings: 13/25
Short offsprings: 12/25
Explanation:
According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:
13 tall pea offsprings
12 short pea offsprings
This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.
That is;
Tall offsprings: 13/25
Short offsprings: 12/25
In percentage, this can be represented as:
Tall offsprings: 13/25 × 100 = 52%
Short offsprings: 12/25 × 100 = 48%
Answer:
Correct answer is Irregular galaxies
Explanation:
An irregular galaxy is a galaxy which does not have a well-defined structure and is not identical to an elliptical or a spiral galaxy. Irregular galaxies do not fall into any class of the galaxies having a distinct size and shape.
These galaxies are rich in dust and gas and do not have a smooth appearance. They appear rough and chaotic in structure when observed through a telescope. Furthermore, these are the type of galaxies which are still not fully understood by the astronauts.
