Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.
Answer:
Option B , Binding Energy
Explanation:
The energy in combining two nucleus is lost in binding them. This binding energy is too large that it causes significant loss of mass and is calculated using the Einstein’s theory of relativity.
When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.
Hence, Option B is correct.
Answer:
C
Explanation:
Nearsightedness is what happens when the image does not reach the retina whereas farsightedness happens when light is focused beyond the retina.
Answer:
b. 17%
Explanation:
Let's begin by stating that the human genome possesses around 3,000 millions of base pairs.
Therefore, if this retrotransposon is around 1,000 base pair and possesses 516,000 copies, it will produce 516,000,000 of base pairs overall.
Let's consider,
516 millions
--------------------- × 100
3000 millions
= 17.2% (approximately 17%)
it gives us a percentage of the human genome which is for this transposon.
In biology, evolution is the change in the inherited traits of a population from generation to generation.
Common traits that have evolved in creatures are multicellular, heterotrophic, obtaining their energy by consuming energy-releasing food substances, reproduction and changes in cell structures.
