Answer:
The correct answer is - 25600 bacteria.
Explanation:
Bacteria can divide and produce double their population very quickly. As mentioned in the question bacteria multiply every 15 minutes to their double number. Finding the number of bacteria after 2 hours is simple mathematics. Two hours means 120 minutes and dividing it to 15. The result will be 8 which mean the bacteria double their colony 8 time so,
100×2 to the power 8 = 100 (initial number of bacteria)×2×2×2×2×2×2×2×2= 25600
Thus, the correct answer is option- 25600 bacteria.
C. Agar provides a solid surface for bacterial growth.
Agar is a substance obtained from red algae which when added to a culture media, provides a solid surface for the growth of bacteria. When the agar is not added then the culture media remains as the broth and when the agar is added then the broth gets solidified.
Agar is added 1.5-2% in the broth to get solidified. The growth of the bacteria depends on the amount of agar added. Agar is used for the growth of bacteria because it has gel like properties which holds the nutrients evenly and the bacteria can use it accordingly.
It's biotic, biotic is basically anything living

Answer:
The correct answer would be - structure of protein and conformation of the R group of the particular amino acid.
Explanation:
The functional properties such as solubility, color, water retention and absorption, texture, foam formation, curdling and other are decided and depends on the structure of the protein and make up of the R-group attached to particular amino acid.
Each amino acid has a single conformation different from other amino acid and which is extremely stable, this unique conformation has its chemical properties that helps in proteins to perform certain and particular catalytic and structural function.
Thus, the correct answer is - structure of protein and conformation of the R group of the particular amino acid.
Therapeutic cloning<span> uses the replication of human embryos to harvest </span>stem cells<span> for medical uses. Majority of the clones are made through a process called "somatic </span>cell<span> nuclear transfer." Basically, a scientist uses a tiny needle to pull DNA material from the nucleus of a donor </span>cell<span> and transfer it into a hollow egg</span>
