If a segment of DNA contains five restriction sites for a particular restriction enzyme then 6 fragments of DNA will remain after the enzyme is used to cut the DNA.
What are restriction sites?A specific restriction enzyme attaches to a section of DNA called the restriction site, which has a length of 6–8 base pairs. There are numerous restriction enzymes that have been identified in bacteria. By cleaving the viral DNA, they naturally render invasive viruses inactive. Type II restriction enzymes identify restriction sites and break the DNA at certain places inside or close to the restriction site.Bacteria include restriction enzymes (and other prokaryotes). They identify and attach to particular DNA sequences known as restriction sites.

Answers
A population of beetles in which some individuals are blue and some individuals are green evolves by chance because more alleles of one color are transmitted to the next generation than alleles of the other color. This mechanism of evolution is known as Genetic drift.
Genetic drift is the arbitrary change in the frequency of a gene variant in a population. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity.Genetic drift is a random or chance process that can produce significant population changes quickly. Recurringly small population sizes, drastic population size reductions known as "bottlenecks," and founder events, in which a new population is created from a small number of people, all contribute to random drift.For example, a population of rabbits having brown and white fur, with the dominant gene being white fur.

What is recessive and dominant?The dominant term is related to the genetic transmission of a trait and is represented, in biology, by a capital letter (A, B or V). While recessive, represented by a lowercase letter (a, b or v), they represent genetic traits transmitted only in the absence of the dominant gene.
With this information, we can conclude that Recessive genes produce proteins considered “defective” as they become inactive. That is, they are hidden (recessive) with the presence of a dominant gene manifesting their characteristics in the absence of their dominant allele.

How does codominance at the molecular level help to explain why evolutionary processes haven't resulted in the elimination of the sickle-cell allele among people of African descent
Answers
Heterozygous individuals have both normal and sickle-cell hemoglobin in their red blood cells and reduced vulnerability to malaria.
What is codominance?In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
The expression of both alleles of a gene pair in a heterozygote is codominant. Offspring are produced as a result, and their phenotype is neither dominant nor recessive. According to the notion of incomplete dominance, this sort of inheritance happens when the phenotype is in between that of the parents and that of the child.
Red blood cells with the A antigen are represented by the IA allele, whereas red blood cells with the B antigen are represented by the IB allele. Since both the normal and sickled shapes can be seen in the blood, the allele is codominant in this way. Consequently, having two recessive alleles causes one to have type O blood.

Which are characteristics of epithelial cells? Select two options.
Answers
Answer:
Epithelial tissue is composed of cells laid out in sheets with strong cell-to-cell attachments. These protein connections hold the cells together to form a tightly connected layer that is avascular but innervated in nature.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.

Glucagon is a hormone that your pancreas makes to assist adjust your blood glucose (sugar) stages. Glucagon will increase your blood sugar degree and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar ranges.
Insulin and glucagon work in what is known as a negative feedback loop. Throughout this system, one event triggers every other, which triggers some other, and so forth, to hold your blood sugar stages balanced.

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.
Answers
When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.
It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll. An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules. An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.learn more about light-harvesting complex here:

An example of two most common helminths which are known to be pathogenic to humans are:
1) Ascaris , the common round worm which causes ascariasis. Its symptoms are internal bleeding, muscular discomfort, fever, etc.
2) Wuchereria (W. bancrofti and W. malayi), the filarial worm that causes filariasis (elephantiasis) . Lymphatic vessels of the lower limbs & genital organs are frequently affected.
The roles that microbiologists play in helping to reduce the number of infections caused by parasitic helminths are :
1) They detect parasites at an early stage of infection, resulting in less harm to the host.
2) The diagnosis provides useful information for identifying and recovering from human parasites.
3) Microbiologists thoroughly research these parasites in an effort to understand how these helminths function, develop, and interact with their surroundings.
4) They collect the sample (feces in case of these diseases) and test them for the parasites that are or maybe the illness's cause.
5) They also provide information on the anthelmintic medications' in vitro activity against the discovered parasite.
