Viral chromosomes exist in a variety of conformations and can be made up of ________. Viral chromosomes exist in a variety of co
Molodets [167]

Answer:

The correct answer is DNA or RNA. Viral chromosomes exist in a variety of conformations and can be made up of <u>DNA or RNA</u>

Explanation:

The hereditary material of viruses is organized into chromosomes of different types. From the genetic point of view, viruses can be classified into DNA or RNA viruses, double helix or single helix, and circular or linear, that is, viral chromosomes are linear or circular molecules of DNA or RNA. Viruses can be classified according to the type of organism they parasitize in: Bacteriophages or phages, animal viruses and plant-type viruses. Viral chromosomes are also subject to the recombination process, this happens when an individual cell is infected simultaneously by two mutant strains of a virus.

Which statement distinguishes the light-dependent (L-D) reaction from the light-independent (L-IND) reaction?
Alja [10]


The correct answer is  (a).

Both L-D and L-IND reactions take place in the chloroplast of the cell but in different parts or locations. L-D reactions take place in the chloroplast thylakoids while L-IND reactions take place in the chloroplast stroma.

Chloroplasts are chlorophyll- filled organelles mostly found in the leaves of green plants.  Chloroplasts are surrounded by a double membrane called the thykaloid membrane that forms long folds within the organelle. In electron micrographs, the thykaloid membranes look like stacked coins. Chlorophyll is located within the thykaloid membranes.

Between the thykaloid  membrane and the chloroplast membrane is a space. This space is what is called the stroma.

Energy was added to the molecule. What processes would occur in the cell to add this energy?
lisov135 [29]
In order for energy to be able to be created, ATP(adenosine triphosphate) needs to form in either photosynthesis or krebs cycle from ADP + P(from NADPH). When ATP is available, huge amounts of energy are released when needed by slicing one P atom from ATP So that it can again become ADP and undergo lots of processes to become ATP again. So energy is added from tearing of Phosphate Atom due to tearing of phosphoanhydride bonds. This is possible because of process known as hydrolysis, when ATP is in equilibrium with water and some electrons. And the process of ADP becoming ATP is recharging and occurs in mitochondria.

The processes are hydrolysis and rechargeation, but most important process is Krebs Cycle, where all of this happens.

Make a table summarising the main components of tobacco smoke and their effects on the human body.​
Delicious77 [7]

Answer: Some of the components in tobacco smoke include:

Nicotine (the addictive drug that produces the effects in the brain that people are looking for)

Hydrogen cyanide.

Formaldehyde.

Lead.

Arsenic.

Ammonia.

Radioactive elements, such as polonium-210

Benzene.

Explanation: Highly damaging components of tobacco smoke include:

tar – is the word for the solid particles suspended in tobacco smoke. The particles contain chemicals, including cancer-causing substances (carcinogens). Tar is sticky and brown, and stains teeth, fingernails and lung tissue

carbon monoxide – is a poisonous gas. It is odourless and colourless and, in large doses, quickly causes death because it takes the place of oxygen in the blood. In people who smoke, the carbon monoxide in their blood makes it harder for oxygen to get to their organs and muscles

oxidizing chemicals – are highly reactive chemicals that can damage the heart muscles and blood vessels of people who smoke. They react with cholesterol, leading to the build-up of fatty material on artery walls. Their actions lead to heart disease, stroke and blood vessel disease

metals – tobacco smoke contains several metals that cause cancer, including arsenic, beryllium, cadmium, chromium, cobalt, lead and nickel

radioactive compounds – tobacco smoke contains radioactive compounds that are known to be carcinogenic.

The effects of tobacco smoke on the body include:

raised blood pressure and heart rate

constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature

less oxygen carried by the blood during exercise

‘stickier’ blood, which is more prone to clotting

damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)

reduced blood flow to extremities (fingers and toes)

increased risk of stroke and heart attack due to blockages of the blood supply.
