What stages of replication do both cycles have in common? Describe the virion action at each of these stages.

Answers

Answer:

Attachment, Penetration and Replication

Explanation:

A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:

1  Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.

2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.

3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

The stages of replication is  Attachment, Penetration and Replication

The following information should be considered:

A bacteriophage means the virus that attacks bacterial cells. The lytic and lysogenic cycles comrpise of two methods of viral replication. In the lytic cycle, the virions generated are released from the host cell while on the other hand in the lysogenic cycle, viral nucleic material are existed into host nucleic material and also they are copied to daughter cells at the time when the host cell reproduces.

The common steps in both cycles are given below:

Attachment – in this step, the bacteriophage attaches itself to the host surface cell to insert its DNA into the host cell.

tRNA molecules bring a specific ________________ to the ribosome, according to the ______________. *
2 points
protein, mRNA anti-codon
protein, tRNA codon
amino acid, tRNA anti-codon
amino acid, mRNA codon

Answers

Answer:

tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.

Explanation:

In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.

The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that :

The pattern in the amino acid sequence of a protein is indicated by mRNA tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.

In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.

What type of cell is shown in the model?

A. Bacterial cell
B. Eukaryotic cell
C. Plant cell
D. Prokaryotic cell

Answers

Answer:

it is a Eukaryotic cell (B)

Explanation:

by process of elimination we can limit it down to B and D, a prokaryotic cell would look nothing like this so therefore it is B

The cell shown in the figure is a model of an eukaryotic cell. An eukaryotic cell consists of all the cell organelles and a well-defined nucleus. Thus, the correct option is B.

What is Eukaryotic cell?

An eukaryotic cell is also known as a true cell. These cells contain all the membranous cell organelles such as mitochondria, chloroplast, etc. and a true well-defined nucleus which are absent in the prokaryotic cell. An outer cell wall or cell membrane is present which encloses the protoplast (living matter) of the cell.

All the animals and plants are made up of eukaryotic cells. These cells contain all the organelles and hence are capable of independent existence. The genetic material is present in the form of DNA (deoxyribonucleic acid) in the nucleus of cells.

Therefore, the correct option is B.

Explanation:

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.


What is the independent variable in this experiment?

Answers

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

The independent variable in this experiment is the amount of light received by each plant.

What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.

Answer:

According to the image, the approximate QT interval is 0.4 seconds.

Explanation:

The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.

Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.

In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:

Then, the estimated QT interval is 0.4 seconds.

What is a vein in rock?

Answers

Answer:

Vein, in geology, ore body that is disseminated within definite boundaries in unwanted rock or minerals (gangue). The term, as used by geologists, is nearly synonymous with the term lode, as used by miners. There are two distinct types: fissure veins and ladder veins.

Explanation:

Material deposits known as geological veins are created when an existing rock fracture is filled with a new mineral.

How rock veins are formed?

   

They are fascinating to planetary scientists because they frequently reveal information about historical water flow. For instance, a lot of rocks have natural pores.

A vein in geology is a distinctive sheet-like body of mineral crystals embedded into a rock. When precipitation occurs, mineral components that are transported by an aqueous solution within the rock mass are deposited as veins.  

Therefore, it is thought that aqueous solutions carrying different elements migrate through rock fissures and deposit their load onto the fissure walls when vein deposits occur, rising water that is hot.

Answer:

Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two

Explanation:

It is not possible to determine information about the geological layers of different locations just by viewing the images, as the question above asks. This is because these two sites have different natural elements that acted on these layers and these fossils differently. In this case, making conclusions only with the visualization of the images, would not promote accurate and correct information. Ideally, a radiometric dating would be performed in both cases, so that accurate conclusions could be created.

Aortic stenosis is one of the most common cardiovascular diseases. This disease is caused by the narrowing of the aortic valve opening, thereby restricting blood flow from the left ventricle to the aorta. Symptoms of aortic stenosis include, among others,  heart palpitations, swollen feet, chest pain, breathing difficulties, sleeping difficulties, chronic fatigue, etc. Aortic stenosis may be cured by transcatheter aortic valve replacement, which is a minimally invasive surgical technique that allows to replace the narrowed aortic valve.
