Reaching for your coffee cup is accomplished by the _____ subdivision of the peripheral nervous system.
Answer:
somatic subdivision
Explanation:
The peripheral nervous system is divided into somatic and autonomic systems. The somatic system is required to transport sensory and motor information to the central nervous system. The somatic system is composed of nerves that connect different parts of the body including sensory fibers, skin, and skeletal muscles. On the other hand, the autonomic system can be subsequently classified into sympathetic and parasympathetic systems, which are required in fight (potentially dangerous) and calm-associated responses, respectively.
The levels of nitrogen and ___ in the atmosphere remain fairly constant but the levels of other gases may vary.
Answer:Oxygen

What is the retrovirus, and how does it work? Name an example of a retrovirus.
Answer:
A retrovirus is a type of RNA virus that inserts a clone of its genome into the DNA of a host cell that it invades. An example of a retrovirus would be HIV.
Hope this helps! :)
Explanation:
A retrovirus is a specific kind of RNA virus that, when it infects a host cell, will insert a clone of its genome into the DNA of the host cell. HIV is an example of a retrovirus that may infect humans.
What is a retrovirus?A kind of RNA virus known as a retrovirus copies its genome into the DNA of the host cell it invades. HIV is a prime example of a retrovirus.
A virus that employs RNA as its genetic material is referred to as a retrovirus. When a cell becomes infected with a retrovirus, the retroviral RNA is converted to retroviral DNA, which is then inserted into the DNA of the host cell.
Acute retroviral syndrome symptoms, which include headache, nausea, diarrhoea, and body pains, are comparable to those of the flu and go away on their own in a few of weeks. A person who has acute retroviral syndrome may no longer have any symptoms, yet they are nonetheless HIV-positive and remain contagious.

What is Ependymal cell?
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.
What is the function of Ependymal cells?The main role of Ependymal cells is formation of CSF.
The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.
Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.
Thus, Ependymal cells are involved in formation of CSF.

Taxonomists today tend to group organisms into the same category based on similar what?
Answer:
characteristics
Explanation:
oranisms are grouped based on shared characteristics
Taxonomists today tend to group organisms into the same category based on their evolutionary history and shared ancestry, as explained in Option A, as this allows taxonomists to construct more accurate and detailed phylogenetic trees.
What is taxonomy?The field of taxonomy is concerned with the classification of living organisms based on their shared characteristics, the aim of taxonomy is to group organisms in a way that reflects their evolutionary history and to provide a standardized system of naming, while earlier taxonomists relied on morphological characteristics, such as the physical appearance of an organism, but modern taxonomists instead use molecular and genetic data to group organisms into categories.
Hence, taxonomists today tend to group organisms into the same category based on their evolutionary histories and shared ancestry, as explained in Option A.

b. mitosis and the cell cycle are different types of cell division that occur in different of cells in a multicellular organism
c. mitosis is a sequence of events within the cell cycle that separates the genetic material
d. mitosis is a type of cell division that occurs in eukaryots and the cell cycle takes place in prokaryots
Answer: C. Cells in meiosis have unique genetic information
Explanation: Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.

What are the mechanism that use to resist the antimicrobial agents?There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.
These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.
There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.

A student hypothesized that EC growth might be affected by the DNA from circulating erythrocytes. Is this student’s hypothesis reasonable?
Answer:
Explanation:
It can be said that this hypothesis is actually not reasonable because circulating erythrocytes do not contain DNA. This can be proven by the Mammalian erythrocytes (rbcs) which ultimately loose their nuclei as well as many other organelles during their maturation process and they don't have nuclei or mitochondria meaning that they are not affected by the DNA.
You decide to focus first on Mutation 1 and Mutation 2.
The F' plasmid appears to "rescue" mutant strain 1 by restoring wild-type inducible expression.
The F' plasmid does not change the phenotype of mutant strain 2; there is still no expression of the lac operon.
There are three possible mutations that could lead to lack of expression: a super-repressor (Is), a promoter mutation (P-) or a mutation in the lacZ gene (Z- ). To determine the effect of introducing a wild-type F' plasmid into a bacterial cell with each of these mutations, you draw out the three possible scenarios.
F' l+ cap+
Determine the expression of the lac operon for each possible partial diploid and for the "unknown" mutation partial diploids (Mutation 1 and Mutation 2).
1. F' lac+/ ts
2. F' lac+/ P
3. F' lac+/ Z
4. F' lac+/ Mutation 1
5. F lac+/ Mutation 2
A. Inducible (wild type)
B. No expression (mutant)
Answer:
Super-repressor (Is) - Uninducible dominant
Binding region is modified by the protein called repressor which prevents the lactose to bind with it. Thus, even the lactose is present the repressor protein is bound to the promoter and can not be detach from it. Transcription is not inducible.
Promoter mutation (P)- - Uninducible recessive
Mutated promoter region inhibits the binding of RNA polymerase that leads to trranscription.
The lacZ gene ( Z-) is mutated - recessive while the normal LacZ gene (Z +) - dominant .
Inducible (Wild type) No expression (Mutant)
F' lac+/ Is No Yes
F' lac + / P- Yes No
F' lac + / Z- Yes No
F' lac +/ Mutation1 Yes No
F' lac+ / Mutation2 No Yes
Mutation 1 and F' plasmid - Inducible wild type
Mutation 2 and F' plasmid - Mutant no expression
Choose a strategy to clone genes known only by a mutant phenotype in organisms with highly efficient transformation procedures and relatively small genomes.
a. cloning by complementation
b. direct sequencing of the mutant genome
c. PCR of the gene and transformation of an organism
d. cloning using a specific cloning vector
Answer:
Option a (cloning by complementation) `would be the correct choice.
Explanation:
In species containing extremely efficient transforming techniques as well as comparatively small genomes, cloning by rearrangement testing is performed to clone gene products mostly by a mutated gene as the rearrangement test was being used to detect mutations.This strategy for cloning through mechanism begins with identifying another yeast mutant that affects something like a plasmid representing a cloned genetic material.The other options in question aren't relevant to the particular circumstance. Therefore the answer to the above seems to be the right one.
What is a biological approach to determining when a mother and her conceptus become separate individuals?
Answer:
Electroencephalography.
Explanation:
Electroencephalography is used to measure brain activity in terms of electrical activity. It is done by attaching electrodes on the scalp, or sometimes by placing electrodes directly in the brain. Using electroencephalography can help determine when the fetus starts having its own brain activities, which means that it is now a separate entity distinguishable from its mother. Using electroencephalography to see brain waves can give us a deeper insight into the age old complicated issue of when a mother and her conceptus become separate individuals.
