A cell's mitochondria cease to function, and the cell has no more energy. will all the transport across the plasma membrane stop?

Answers

Not all transport will cease. Active transport will cease, because it requires energy. However, passive transport requires no energy from the cell.

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.

Which response best explains why promoters for the same sigma subunit do not have identical sequences?

Answers

This enables the differential expression of genes. While the sigma promoter is canonically placed upstream of genes at position -10 and -35 across organisms, they differ slightly in sequence. This allows for the binding of sigma factors of RNA polymerase by different affinities across different gene promoters. Expression of genes will, therefore, be high where the sigma factors bind with high affinity and vice versa.
The correct response is,
the sequences within the promoter region at -10 and -35 are the most important for recognition by the sigma subunit.
Promoter region is the DNA sequence located upstream of the corresponding gene. Promoters for genes are essential as RNA polymerase recognizes the promoter region and binds to it forming the holoenzyme complex which can inititate transcription of the gene located downstream.
Sigma factor is the transcription factor found in bacteria, RNA polymerase has a subunit for the sigma factor, this factor only can recognise the sequences in the promoter region and bind to it thus initiating transcription. 

Promoters usually have 2 parts of conserved regions, -10 element and -35 elements. Both these regions have conserved sequences.
The sigma factor is capable of identifying these conserved sequences at these particular locations of the promoter and can bind to these sequences.
once the sigma factor binds to these regions, RNA polymerase too binds and forms a transcription initiation complex and then transcription of the downstream gene is initiated.

Therefore promoters need not have identical sequences for the sigma factor to bind, as long as the -10 and -35 regions have conserved sequences the sigma factor can bind and transcription initiation will be followed.

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.

Answers

B. Hydrogen bonds make the positive sides of water molecules stick to each other
Final answer:

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.

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.

Answers

I'm thinking that it is 2

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.

Occlusion of the left anterior descending artery during a myocardial infarction would interrupt blood supply to which structures?

Answers

I believe it would interrupt blood supply to the left and right ventricles and much of the interventricular septum. Myocardial infarction (heart attack) occurs when blood flow decreases or  fails to reach parts of the heart, causing damage to the heart muscle. Occlusion of the left anterior descending artery may cause infarction of the anterior wall of the left ventricle, manifested as precordial ST-segment elevations. 

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?

Answers

The correct answer is "Hfr strains have the F plasmid integrated into the chromosome".

This is in the context of horizontal gene transfer in bacteria. This gene transfer consist of transferring an "F plasmid" in a process called bacterial conjugation. Bacteria with the F plasmid are termed as "F+ strains". The key difference between an Hfr strain and a F+ strain is that while they both have the F plasmid; the Hfr strain have the F plasmid integrated to its chromosome while the F+ strain have the F plasmid not integrated to the genetic material and only freely floats in the cytoplasm.

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 nurse is preparing a woman for discharge after a birth and notes the mother's record indicates rh negative and rubella titer is positive. which nursing intervention will the nurse prioritize?

Answers

The answer is to assess the Rh or as called as rhesus of the baby. In addition, the cord blood should be evaluated to determine the Rh type of the infant. If it is negative, there is no need for any further action or concern. However, if it is Rh positive the mother needs to be evaluated for possible supervision of RhoGAM. 

The measures for giving RhoGAM are as follows: 

• The woman must be Rho (D) negative.

• The woman must not have anti-D antibodies which are must not be sensitized. 

• The infant should be Rho (D) positive in which the fetus cord blood is checked after birth.  

• A direct Coombs test which is a test for antibodies performed on cord blood at delivery and must be weakly reactive or negative.


All of these requirements to be accomplished in the first 72 hours of birth, so the mother can obtain RhoGAM in the appropriate time frame.

The neurons of the central nervous system are also known as ________.

Answers

The neurons of the central nervous system are also known as _interneurons_.
Being cells between sensory and motor neurons, these cells of the brain and spinal cord are the decision-makers of the nervous system.

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.
