Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.
Out of the following given choices;
contain ribose
consist of two strands
made of nucleotides
have an R group
The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.
<u>Cellular respiration</u> is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level.
Explanation: In simpler words, it provides energy for the cell to do basic needs.
The correct answer is seismic waves.
A sudden movement of the Earth's crust followed by the production of seismic waves is known as an earthquake. The seismic waves travel outwards from the source. The sudden vibration or ground motion is generated due to a brisk discharge of accumulated energy.
The vibrations, which travel via Earth carrying the energy discharged at the time of an earthquake is known as seismic waves. The earthquakes are usually determined with a help of seismometer, called seismograph.
