Answer:
Explanation:
Density is a characteristic property bodies and materials, and is defined as the relationship between the mass and the volume , as shown below:
(1)
In the case of the neutron star, we know it has the same mass as the Sun:
And its radius is
On the other hand, if we assume this neutron star has a spherical shape, its volume can be calculated by the following formula:
(2)
(3)
(4)
Substituting (4) in (1):
(5)
Finally:
Distance= speed x time
distance = 2.6 m/s x 120s
distance= 312 meters
Answer:
D. DNA
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
Deoxyribonucleic acid (DNA) is a strand of evidence which helped to provide a link in the evolution of whales from land mammals on 4 legs to a sea mammal with fins.
Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
