Answer:
D. increasing the number of mitochondria
Explanation:
The mitochondria are membrane-bound cellular organelles found in the cell of an eukaryote. Mitochondrion is responsible for the production of energy since the process which releases the energy (cellular respiration) occurs in it.
In an experimental procedure whereby the amount of energy which is produced by a cell is about to be increased will involve the increase of the number of mitochondria in that cell. Since more mitochondria means more energy production.
Answer:
D. an educated guess or tentative explanation for a natural phenomenon.
Explanation:
A hypothesis is an idea or explanation that is tested through study and experimentation. Outside science, a theory or guess can also be called a hypothesis. In other words, hypothesis is defined as a proposed explanation for a phenomenon.
A trial solution to a problem as a hypothesis is often called an educated guess because it provides a suggested outcome based on the evidence.
Cell X is likely a prokaryotic cell. Option B) is the correct answer.
<u>Explanation</u>:
- The prokaryotic cells are present in unicellular organisms such as bacteria and lack Nucleus in it. The cell X is not filled with x-mark in the nucleus.
- The prokaryotic cells consist of the cell membrane, cell wall and a genetic material composed of DNA. All these are marked with x-mark for cell X.
- Chloroplasts are not present in prokaryotic cells and the space for it is left blank in cell X without the x-mark.
- This information clearly shows that prokaryotic cell structure is viewed likely in cell X.
Answer:
The correct answer is a. Zygote
Explanation:
Edouard van Beneden was a zoology professor at the University of Liège whose worked showed how chromosomes are organized during gamete formation or during meiosis process.
During meiosis, the chromosomes number is reduced to half so each gamete contains half of the chromosome found in somatic cell and are called haploid cells. This reduction in chromosome number is necessary to bring the correct number of chromosomes in the zygote.
During fertilization, sperms fuse with eggs to produce a single diploid cell that is known as zygote. So the zygote has 46 chromosome in which half comes from sperm and half from the egg.

_____________________________________</h2><h2>REPLICATION</h2><h3>---------------------------------------------------------------------------------------------</h3><h3>Definition:</h3>
DNA replication is the process by which a double-stranded molecule of a DNA is replicated(copied) to produce two morphologically and chemically identical DNA molecules.
<h3>__________________________________________________</h3><h3>Why is it Important:</h3>
Replication is a very important process for the living organism, because in a cell division, the two new daughter cells are produced which must contain the same genetic information or the DNA just like the parent cell. It cant be less or more than the parent cell.
<h3>__________________________________________________</h3><h3>Steps of Replication:</h3>
Replication occurs in three major steps,
1- the opening of the double helix and separation of the DNA strands,
2- the priming of the template strand.
3- the assembly of the new DNA segment.
