The Lederberg experiment that used the technique of replica plating showed that mutations _____ and are not a result of _____.
The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
What is a random mutation?Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.
Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

The number of chromosomes in a human gamete is __________; this is referred to as a __________ chromosome number.
Answer:
23, haploid
Explanation:
there are 23 chomrosomes in both a egg and sperm cell
this makes them haploid as they have a single set of unpaired chromosomes
hope this helped
The number of chromosomes in a human gamete is 23, and this is referred to as a haploid chromosome number because in a diploid cell there are a total of 46 chromosomes.
What are the chromosomes?The chromosome numbers vary in the diploid cell of the human and in the haploid cell of the human, which is in the sperm and in the egg cell. The diploid cell has 46 chromosomes, and this cell can undergo either mitosis to produce an exact equal cell with 46 chromosomes or it can undergo the meiosis process to produce the 23 chromosomes. The mitosis is helpful for filing up the cut site, for cell duplication, or for body size growth, and the meiosis is helpful for gamete formation and helpful for the reproduction.
Hence, the number of chromosomes in a human gamete is 23, and this is referred to as a haploid chromosome number.

A. Advantage: Hydrogen is easy to store.
Disadvantage: Hydrogen is scarce.
B. Advantage: Hydrogen is easy to transport.
Disadvantage: Hydrogen emits pollution.
C. Advantage: Hydrogen is an efficient form of energy.
Disadvantage: Hydrogen is expensive.
D. Advantage: Hydrogen fuel has established infrastructure.
Disadvantage: Hydrogen is scarce.
Hydrogen is used as an energy source as it is an efficient form of energy compared to the other sources, but it is expensive. Thus, option C is correct.
What is hydrogen energy?
Hydrogen energy is the use of hydrogen gas in the production of energy that is more efficient than the other sources as it has a greater fuel conversion rate than petrol and diesel.
Ther hydrogen energy is also a disadvantage as it is expensive as it includes steam reforming and electrolysis which are costly processes and hence are not used globally.

A particular viral genome can replicate in 8 hours. If you start with 55,000 copies of this genome, about how many copies would be present in a host's cell after 48 hours of growth
If a viral genome can replicate in 8 hours and the starting copies is 55,000, the number of copies after 48 hours would be 3,360,000 copies
Replication ratesThe starting number is 55,000 and replication happens every 8 hours.
Starting from 0 hours, the genome would 55,000
After 8 hours = 55,000 x 2 = 110,000 copies
After 16 hours = 110,000 2 = 220,000 copies
After 24 hours = 220,000 x 2 = 420,000 copies
After 32 hours = 420,000 x 2 = 840,000 copies
After 40 hours = 840,000 2 = 1,680,000 copies
After 48 hours = 1,680,000 x 2 = 3,360,000 copies
