a bacterium is infected with an experimentally constructed bacteriophage
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria. Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

Our sun is a low mass main sequence star at the middle of its life cycle. Explain how the
appearance of the sun's location on the HR diagram will change as it continues to the end of
its life cycle.
Answer:
Accordingly, when our Sun comes up short on hydrogen fuel, it will grow to end up a red monster, puff off its external layers, and after that settle down as a minimal white small star, at that point gradually chilling off for trillions of years. All incredible, in the long run — in around 5 billion years — our sun will, as well. When its supply of hydrogen is depleted, the last, sensational phases of its life will unfurl, as our host star extends to wind up a red Goliath and afterward shreds its body to consolidate into a white smaller person Explanation:

Answer:
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What does it mean when we say that replication is a Semi-Conservative process?
Answer:
Semiconservative replication describes the mechanism of DNA replication in all known cells. ... This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each copy conserving (replicating) the information from one half of the original DNA molecule.
What happens when an action potential is produced with a signal that is stronger than threshold?
A)
weaker action potential generated
B)
no action potential generated
C)
action potential has same strength as threshold
D)
stronger action potential generated
Answer:
C) action potential has same strength as threshold
Explanation:
What happens when an action potential is produced with a signal that is stronger than threshold action potential has same strength as threshold
When an action potential is produced with a signal that is stronger than the threshold, the resulting action potential is typically stronger or more intense compared to a standard action potential. The answer is D) Stronger action potential generated.
The threshold is the minimum level of depolarization required to initiate an action potential in a neuron. If the signal surpasses the threshold, it means that the depolarization is greater than what is necessary to trigger the action potential.
When a stronger signal is received by the neuron, it results in a larger influx of ions (such as sodium) into the neuron, leading to a more pronounced depolarization of the cell membrane.
As a result, the action potential generated will have a higher amplitude or voltage compared to a regular action potential. Therefore, the answer is D) Stronger action potential generated.

why is it important photosynthetic organisms to have access to water
Answer:
Plants also need water for photosynthesis. Photosynthesis is what plants do to create their food, and water is critical to this process. ... The water from the leaves evaporates through the stomata, and carbon dioxide enters the stomata, taking the water's place. Plants need this carbon dioxide to make food.

By 12 weeks, the uterus is just ____________ to the level of the ____________ and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the ____________ .
Answer: 1. superior 2. pubic symphysis 3. urinary bladder
Explanation:
Given our understanding of the human anatomy, we can confirm that by 12 weeks, the uterus is just superior to the level of the pubic symphysis and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the bladder.
As the question tells us once the spaces are filled in, the uterus, which holds the fetus during development, expands as the fetus grows in size. This expansion causes it to extend to the spaces superior to the pubic symphysis and the space occupied by the bladder.
The expansion of the uterus into the space occupied by the bladder causes this organ to have very limited space to expand, thus greatly limiting the amount of urine it can hold which causes more frequent trips to the bathroom.

what molecule makes instructions for proteins and is located inside a eukaryotic nucleus
Answer:
DNA stores that info
Explanation:
In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).
The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.
The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.
The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.
During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.
The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

regulation of the cell cycle is dependent on cyclins and cyclin-dependent kinases. the key that allows a cell to progress beyond the restriction point is
The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.
Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).
This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.
CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.
For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.
