The body's reaction to information is to send neurons to the brain. This can be facilitated by the transmission of nerve impulses throughout the body with the help of neurons.
Neurons may be characterized as nerve cells that significantly sends or receives signal to and from the brain. These cells typically communicated with other cells of the body with the help of a junction which is known as a Synapse.
According to the physiology of the function of neurons, sensory neurons perceive as a set of information or messages from various sense organs like eyes, ears, nose, tongue, and skin and send them directly to the brain.
While the function of motor neurons is understood by the fact that these neurons send the perceived information and messages from the brain to the entire body at the target site.
Therefore, the body's reaction to information is to send neurons to the brain.

Earlobes can be either attached or detached. The allele for attached earlobes
is recessive (e), and the allele for detached earlobes is dominant (E). What
must be true if a boy is born with attached earlobes?
A. He has a heterozygous genotype.
O B. He has no E alleles.
C. He has no recessive alleles.
O D. He has one of each allele,
SUBMIT
If a boy is born with connected earlobes, he has no E alleles because the allele for detached earlobes is dominant (E), whereas the allele for attached earlobes is recessive (e). So, the correct option is B.
A dominant allele is one that will overpower a recessive allele's expression. Hence, only the trait linked to the dominant allele is manifested when a dominant allele and recessive allele coexist in the genotype of offspring. Consequently, for a recessive allele phenotype to manifest, both of the recessive allele must be present in the progeny.
A recessive allele causes connected earlobes (e) while the dominant earlobe detachment allele (E)
A child with the EE genotype would have disconnected earlobes.
As features of dominant alleles are manifested in heterozygous genotypes, offspring with the Ee genotype would also have disconnected earlobes. Only the child with the ee genotype would have connected earlobes. A homozygous recessive genotype is genotype ee.
Thus, the correct option is B.

Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
Some viruses uses Lysogenic cycle to insert the viraldna into the host cell dna before it enters a lytic cycle.
The lysogenic cycle also referred to as nonvirulent infection, includes the virus integrating its genome with the genome of the host cell in order to replicate without destroying the host. An example is the structure of a bacteriophage. To reproduce, the phage should first penetrate the host cell.
The lysogenic cycle is characterized by The phage infecting a bacterium and inserting its DNA into its chromosome, enabling the phage DNA (now known as a prophage) to be replicated and transferred on alongside the cell's own DNA.
The lytic cycle includes virus reproduction by utilizing a host cell to produce more viruses, which then ruptured out of the cell. The viral genome is incorporated into the host cell genome during the lysogenic cycle, infecting it from within.

Answer:
Water has various properties as frozen ice is less dense as 0.9340 g/cm cube compared to density of water at room temperature is 997 kg/m cube.
Explanation:
Correct answer: B). Sac Fungi
Yeast is the single-celled microorganism that is classified with the molds and mushrooms in the kingdom Fungi. It is a member of Group Ascomycota, which is also known as sac fungi.
A truffle is the fruiting body of the subterranean ascomycete fungus. These are found in close association with the tree roots as it is an ectomycorrhizal fungus.
Hence, the correct answer would be option B.
