There is only 1 negative choice here, so you can solve by common sense.
C. They reproduce slower than unicellular organisms.
This is true because, for example, think of humans. We take 9 months to reproduce uses multiple stages of meiosis. Unicellular organisms on the other hand, such as bacteria, are asexual and use binary fission to reproduce, which happens very quickly, but creates less diversity.
Answer:
A. Isotope
Explanation:
For example you have Carbon 12 with 6 protons and 6 neutrons and Carbon 14 with 6 protons and 8 neutrons.
Denser salt water makes the eggs to float in the water.
<u>Explanation:
</u>
Egg will always sink in water, as egg is denser than water.
But we can make it to float by means of adding excess salt to the water. Adding more salt to water makes it as denser than egg. Denser water makes less dense egg to float in water.
So, making the water as denser one leads to the floating of egg in the water.
