Natural selection is the changes of size and shape of living things in.
Natural selection is the changes of the size and shape of living things in nature.
What do you mean by Natural selection?Natural selection may be defined as favorable variations through which organisms are better adapted and survive in the environment.
Natural selection is an agent of evolution. It is the component that forces the species to change and diverge from its parental species over a period of time.
It may alter the size as well as the shape of living organisms according to their need in nature for survival.
Therefore, natural selection is the changes of the size and shape of living things in nature.

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

Answer:
Similar DNA
Explanation:
We and our mom will have similar DNA. We inherit half of our DNA from mother and half from father.
Our DNA is not different or completely same (identical) because, we inherit 50% of our DNA from mother. Hence, we can confirm that it is similar.
1. A parent has the Bb genotype. Due to the Law of Segregation, what percent

2. What law of genetics says that organisms inherit each all ele from their
parents separately?
3.
One parent has curly hair, and one parent has straight ha r. Their child has
wavy hair. What type of dominance is this?
Answer:
1. 25% if it also includes the other parent's unknown alleles and 50% if it does not take into account the other parent.
2. The law of independent assortment states that organisms inherit each allele from their parents separately.
3. The type of dominance is incomplete dominance.
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.

What kind of activity is pinge made up by ?It is the human activity in which the extractions are done in order to make the use of the resources . It is the artificial human activity.
This depression or sink-hole is usually caused out by collapse of the old underground mine works which are close to Earth's surface.Unlike any natural landforms , a Pinge is the direct result of the human activity. The collapses do make up big larger holes that almost makes the pinges in the process of mining.
Pinge is also formed by the surface in which the land is not supported properly and the extraction has made the holes in the lands because of the more pressure and the type of extracting machines that are being used in it.
