*The rate at which radioactive decay occurs.
*How much radioactive decay has occurred.
The clear explanation for the forces mentioned in the question given below
Explanation:
1.A non-contact force that is generated between charged objects is known as "Magnetic force" eg: train tracks, new roller coaster, a compass, motor.
2.A non-contact force that is generated from moving charges is known "Electrical force". eg: Electric charge in a bulb.
3. A non-contact force that exists between objects with mass is known as "Gravitational force". eg: The force that causes apple to fall down from trees, The force thatt makes us to walk instad of floating.
4.A force that requires physical contact between objects is known as "Contact force". eg: moving a chair or table across a room, kicking a ball
The movement of the continents
in the continental drift hypothesis causes the land to rise or fall. The earth’s
crust is dynamic and it is constantly moving slowly. If the continent rises,
the sea level decreases and if the continent goes downward, sea level rises. Hope this helps!!
Answer:
2n, n, diploid
Explanation:
<em>When the somatic cells of human are in interphase, the ploidy level is denoted as </em><em>2n (diploid)</em><em>. The ploidy level of the human's gametes is denoted as </em><em>n (haploid)</em><em>. The 2n number of a human is </em><em>diploid</em><em>.</em>
Somatic cells are also known as vegetative cells and all somatic cells of humans have diploid number of chromosomes. At interphase, the number of chromosome remains diploid (2n) but the amount to DNA is doubled at the synthesis phase of the interphase.
Human gametes are formed through meiosis - the division of sex cells in the human body. Meiosis results in the halving of number of chromosomes of cells. Hence, all human gametes contain half the number (n = 23) of chromosome of vegetative cells.
Humans are diploid organisms with diploid (2n = 46) number of chromosomes in their vegetative cells.
Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!
Hope this helps!
