Answers

Answer 1

The best predictions in this are that when a normal cell is exposed to a retrovirus, the reverse transcriptase will make DNA from the viral RNA, which can be incorporated into the host's genome and subsequently transcribed and translated.

A specific kind of virus that uses RNA as its genetic material rather than DNA. Reverse transcriptase is an enzyme that is used to integrate into the DNA of the host cells. This enables the virus to replicate often in the host cells. Human immunodeficiency virus (HIV), which causes AIDS, is a class of retrovirus.

Retroviruses, including the HIV and hepatitis B viruses, have RNA rather than DNA in their genetic makeup. Reverse transcriptase molecules are also present in them.

Correct Question:

Retroviruses such as HIV and hepatitis B virus use RNA as their genetic material rather than DNA. In addition, they contain molecules of reverse transcriptase, an enzyme that uses an RNA template to synthesize complementary DNA. what will be the best predicts and what will happen when a normal cell is exposed to a retrovirus?

Answer 2

When a normal cell is exposed to a retrovirus such as HIV or hepatitis B virus, the virus will enter the cell and use reverse transcriptase to convert its RNA into a complementary DNA form.

This DNA can then integrate into the host cell's genome and become a permanent part of the cell's genetic material. The best predictors of a retroviral infection are exposure to the virus and the presence of viral genetic material or antibodies in the blood. This is because retroviruses can persist in the body for long periods of time, even if the person does not show any symptoms of illness. Once a retrovirus has integrated its genetic material into the host cell's genome, it can alter the normal functioning of the cell and potentially cause disease. For example, in the case of HIV, the virus attacks and destroys immune cells, leading to a weakened immune system and the development of acquired immunodeficiency syndrome (AIDS). Similarly, in the case of hepatitis B virus, the virus can cause liver damage and lead to the development of liver disease. In conclusion, the integration of retroviral genetic material into the host cell's genome is a critical step in the development of retroviral infections and diseases. The presence of viral genetic material or antibodies in the blood is the best predictor of a retroviral infection, and exposure to the virus is a risk factor for the development of retroviral illness.

estimate area of endoplasmic reticulum when it is in rectancular form using a model for its structure

Answers

The endoplasmic reticulum (ER) is a complex and dynamic organelle found within eukaryotic cells. Its structure can vary depending on the cell type and the functions it is performing.

 

In a rectangular model, the ER is composed of a series of flattened, stacked cisternae that form a network of flattened tubules and vesicles. To estimate the area of the ER in this model, one would need to know the length and width of the cisternae, as well as the number of cisternae present.

The area of a rectangle can be calculated using the formula:

length x width

Therefore, if the length and width of each cisterna are known, the total area of the ER can be calculated by multiplying the area of one cisterna by the number of cisternae present.

The structure of the ER can be more complex than a simple rectangle, and its size can also vary greatly depending on the cell type and stage of development. Also, there are different types of ER, like rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER), that have different structures.

Answers

NADH does not play a role in cellular respiration by oxidizing pyruvate.

NADH participates in oxidation in cell processes such as glycolysis to aid in the oxidation of glucose. The energy stored in this reduced coenzyme NADH is supplied by the TCA cycle during aerobic cellular respiration and powers the electron transport process in mitochondrial membranes.

In the presence of oxygen, pyruvate is converted into an acetyl group that is attached to a coenzyme A carrier molecule. The resulting acetyl CoA can enter a variety of pathways, but the acetyl group is usually delivered to the citric acid cycle for further catabolism.

Three carbons are converted from pyruvate to acetyl CoA, a two-carbon molecule attached to coenzyme A. This reaction requires a molecule of coenzyme A, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.

Transcription is the process of formation of RNA from DNA. RNA production takes place through various steps and the main enzyme responsible for it is RNA polymerase.

RNA polymerase attached to the promoter gene, after the double helix is unwounded. Complimentary nucleotides are selected as per the template strand and mRNAs are produced. When it reaches the terminator, the process stops, RNA polymerase and mRNA are released. So the correct order of step is as follows.

The RNA polymerase identify the gene which needs to be transcribed.RNA polymerase attaches to a part called promoter, which is a set of nucleotide act as the starter of the gene expression. This is called initiation. The double helix unwind and strands are separated.The RNA polymerase starts transcription, use the template strand to produce complimentary RNA. Each nucleotides are added in accordance to the base pairing. This stage is elongation.The RNA polymerase reaches the terminator, which is also a set of nucleotides that signals to stop the process. RNA polymerase as well as the RNA strand separates from DNA. Double helix is reformed. This is called termination.

The major elements of the pathway that blood takes through the heart is Vena cava, right ventricle, pulmonary artery, left ventricle, aorta.

Blood enters the right atrium from the body, travels to the right ventricle, and is forced into the pulmonary arteries in the lungs. After collecting up oxygen, the blood returns to the heart via the pulmonary veins into the left atrium, then to the left ventricle, and finally to the body's tissues via the aorta.

Through the pulmonary valve, the right ventricle sends oxygen-depleted blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and sends it to the left ventricle via the mitral valve. The left ventricle sends oxygen-rich blood to the rest of the body via the aortic valve.

Electrical Stimulation of the Brain (ESB) is a technique which involves passing a mild current through the brain to activate certain structures without damaging them.

Electrical brain stimulation (EBS), also known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to stimulate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current. EBS is employed in both scientific and therapeutic settings.

Even at low currents and up to distances of four millimeters distant, macrostimulation stimulates neurons sparsely surrounding the electrode, according to research using two-photon excitation microscopy. This occurs without specifically selecting additional neurons that are located considerably closer to the electrode tip. This is because whether or not a neuron has axons or dendrites that pass within a 15 m radius of the electrode tip determines whether or not that neuron is activated. The volume around the tip of the neuron that activates axons and dendrites grows when the current is increased, and this also causes a rise in the number of neurons activated. Instead of synaptic activation, activation is most likely caused by direct depolarization.

Much of the excess carbon dioxide in the atmosphere, which results from activities like burning fossil fuels, is believed to dissolve in the ocean rather than accumulate in the atmosphere. What remains in the atmosphere, along with other gases, is responsible for a rise in global temperatures. This is known as "global warming" and it occurs because of what is called "greenhouse effect," whereby increased concentrations of gases in the atmosphere absorb and radiate heat back to Earth. Global warming is contributing to "climate change" which is causing changes to many of the Earth's ecosystems.

Which of the following characteristics of a red blood cell increases its ability to carry oxygen to the tissues?
1) Lacking mitochondria, RBCs rely exclusively on anaerobic fermentation to produce ATP.
2) The cytoplasm of an RBC consists mainly of a 33% solution of hemoglobin.
3) RBCs lose nearly all organelles during their development.
4) The cytoplasm also contains an enzyme, carbonic anhydrase.
5) Lacking a nucleus and DNA, RBCs also are incapable of protein synthesis and mitosis.

Answers

RBCs lack mitochondria, hence they can only create ATP by anaerobic fermentation.

Red blood cells were designed to carry oxygen. They feature a bi-concave form that optimizes their contact area to absorb oxygen, a thin membrane that allows gases to readily permeate through it, are small & flexible so they may fit through small vessels, and contain haemoglobin, which binds to oxygen. Red blood cells can bend and stretch, they can cling to certain other cells, and they can communicate with immune cells. Their membrane has a variety of effects on this. The composition of the membrane has a significant impact on these functions. The protein that transports oxygen is called haemoglobin, and it is almost exclusively located in red blood cells (RBCs) rather than dispersed in plasma. Relative to a flat disc of the same size, the cell's biconcave shape has a larger surface area.

The cytoplasm of red blood cells RBC mainly consists of a 33% solution of hemoglobin these features increase the capacity to carry oxygen to tissues. Here option 2 is the correct answer.

Hemoglobin is an iron-containing protein that binds to oxygen and gives red blood cells their characteristic red color.

The high concentration of hemoglobin in the cytoplasm of red blood cells allows them to carry a large amount of oxygen, which they can then transport to the tissues throughout the body. This characteristic is key to the red blood cells' ability to carry oxygen.

All the other options mentioned are correct as well, but they don't have a direct relationship with the ability of red blood cells to carry oxygen. Lacking mitochondria, RBCs rely exclusively on anaerobic fermentation to produce ATP, and RBCs lose nearly all organelles during their development.

segmented worms. The segmented structure of annelids help them
move and survive predators. They can live in saltwater, freshwater,
and damp soil. Most of them are scavengers and burrow into soil or
sand.
What is a common feature of
ALL of Phylum Annelida?
A have a closed-circulatory system
B. scavenge for food
C. have a segmented body plan
D. contain anti-coagulant factors

Answers

A common feature of all Phylum Annelida is : C.) have a segmented body plan.

What features do annelids possess?

The term "annelida" also refers to segmented worms. It is distinguished by having a segmented body plan, which is a characteristic shared by all individuals in this phylum. Because of their more complicated and flexible bodies due to this segmentation, they can move around and fend off predators.

Some of them may survive in a variety of habitats, including freshwater, saltwater, and moist soil. However, the majority of them are scavengers that burrow into the ground or sand. Other traits, including having a closed circulatory system or anti-coagulant substances, can differ between species.
