The neurons of the central nervous system are also known as ________.
Final answer:
The neurons of the central nervous system are specialized cells that make up the brain and spinal cord, crucial for processing and transmitting sensory information.
Explanation:
The neurons of the central nervous system are also known as the fundamental building blocks of the central nervous system (CNS), which includes the brain and the spinal cord. The CNS is central because it processes sensory information, like touching a hot stove or seeing a rainbow, and then sends signals for action through the peripheral nervous system (PNS). Neurons are specialized cells that transmit information via electric signals and form connections with other neurons at synapses. There are approximately 100 billion neurons in the human brain, each with the capability of creating numerous synapses. The structure of neurons consists of a dendrite, a soma, and an axon that collectively facilitate the reception and transmission of information within the nervous system.
A cell's mitochondria cease to function, and the cell has no more energy. will all the transport across the plasma membrane stop?
A cell's mitochondria cease to function, and the cell has no more energy. No, the transport will not stop but the transport will be helpful with the help of energy that is the ATP molecules are transferred in order to give the energy.
What is the cell organelle that provides the energy for the cell ?The cell organelle that provides the energy for the cell organelle is the mitochondria.
In case the cells are not able to get the transportation for certain molecules but there is a need for the transport then in that case certain helpers will help the molecules.
Carrier proteins are the proteins that help in the transportation of molecules from one extracellular medium to intracellular or vice versa. ATP helps in the transportation of such molecules where the molecules are helping to certain passing mechanisms.
Facilitated diffusion is one such help to it and reverse osmosis as well.

How does an f+ cell differ from an hfr cell? how does an f+ cell differ from an hfr cell? hfr strains have the f plasmid integrated into the chromosome. f+ cells have no plasmids. hfr cells cannot perform conjugation. hfr strains can no longer reproduce?
In summary , the most difference between an F+ cell and an Hfr cell are the area of the F plasmid (extrachromosomal vs. coordinates into the chromosome) and the degree of DNA exchange amid conjugation.
Bacterial cell explained.
An F+ cell and an Hfr cell are both sorts of bacterial cells that have the F plasmid, too known as the richness calculate. In any case, there are critical contrasts between them:
F+ Cell (F-Positive Cell):
An F+ cell carries the F plasmid as an extrachromosomal circular DNA atom partitioned from the bacterial chromosome.The F plasmid in an F+ cell can duplicate autonomously and is competent of conjugation, which is the exchange of hereditary fabric to a beneficiary cell.F+ cells can act as givers amid conjugation and can exchange the F plasmid to an F- (F-negative) cell, changing over it into an F+ cell.Hfr Cell (High-Frequency Recombination Cell):
An Hfr cell moreover carries the F plasmid, but it is coordinates into the bacterial chromosome instead of existing as a isolated plasmid.Integration of the F plasmid into the chromosome comes about in an Hfr strain.Hfr cells have the capacity to perform conjugation and exchange both chromosomal and plasmid DNA to beneficiary cells amid conjugation.However, the exchange of the whole F plasmid from the Hfr cell to the beneficiary cell is regularly fragmented, because it requires the replication and recombination of the coordinates F plasmid with the beneficiary chromosome.
It's imperative to note that Hfr strains can still replicate, and they hold the capacity to perform conjugation. In any case, the total exchange of the F plasmid and chromosomal DNA to the recipient cell seldom happens amid conjugation with Hfr cells.
In summary , the most difference between an F+ cell and an Hfr cell are the area of the F plasmid (extrachromosomal vs. coordinates into the chromosome) and the degree of DNA exchange amid conjugation.

the boundary between which two tectonic plates is most similar geologically to the plate boundary at the Mid-Atlantic Ridge?
A) Pacific and Nazca
B)Cocos and Caribbean
C)Nazca and South America
D)Eurasian and Indian-Austrailian
The correct answer for the boundary between which two tectonic plates are most similar to the plate boundary at the Mid -Atlantic Ridge is ( D ) : Eurasian and Indian-Australian
Tectonic plates are parts of the Earth's crust and uppermost mantle which are collectively called lithosphere. tectonic plates are made up of two distinct materials which are:
Ocean crust Continental crustThe plate boundary between two tectonic plates ( Eurasian and Indian Australian boundary ) appears geologically similar to the plate boundary at the Mid-Atlantic Ridge because the Mid-Atlantic Ridge ( divergent plate boundary ) occurs along the plate boundary where the ocean floors are formed as plates separated from each other.
Hence the correct answer from the options is Eurasian and Indian-Australian boundary

What are responsible for the structure and functions of organisms
Julia had a sibling who died because of a genetic disease as an infant. Before having children, she and her husband Tobias get genetic testing and counseling. They are unlucky.
For the GAA gene, Julia has one normal allele and one totally non-functional allele. Tobias has one normal allele and one totally non-functional allele.
If any of their offspring test positive for Pompe disease, when are symptoms likely to develop (remember, both parents have one non-functioning allele, 0%GAA)?
1.) Before the age of nine months
2.) Anytime during adolescence up through middle adulthood.
The right answer is A.
It turns out that this family possesses in their gene the infantile form of Pompe disease, so the disease will appear early in the offspring.
Pompe disease is caused by a deficiency of lysosomal acid α-glucosidase resulting from mutations in the GAA gene. The clinical spectrum ranges from a rapidly fatal multisystem disorder (classical, beginning before 1 year) to less severe myopathy in adults.

Explanation:
Which of the following is true of hydrogen bonds
A. Hydrogen bonds are strong
B.hydrogen bonds make the positive sides of water molecules stick to each other
C.hydrogen bonds are not strong but there are plenty of them in a drop of water.
Hydrogen bonds are not very strong, but there are many of them in a drop of water, making them crucial for the properties of water.
Explanation:The correct answer to the question is that hydrogen bonds are not inherently strong, but there are plenty of them in a drop of water, which makes them vital for water's unique properties (option C). A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Although they are weak when compared to covalent bonds, they are nevertheless very necessary for the properties of water due to their large quantity.
