Baltimore Classification groups do COVID-19 fall under the coronavirus family.
Which of the Baltimore Classification groups does COVID-19 fall under and why?The Baltimore Classification System is a type of system for the classification of viruses that is based on the type of genome and its replication. The system was developed by David Baltimore. Viruses do not contain a proper system for the translation of protein, we know that every virus depends on host translational machinery. COVID-19 is caused by the virus known as SARS-CoV-2. It is part of the coronavirus family, which includes common viruses that cause a variety of diseases from head or chest colds to more severe (but rarer) diseases such as severe acute respiratory and the Middle East respiratory syndrome

PLEASE HELP ME!!!! A microbiologist ran some tests on pure enzymes extracted from a pathogenic bacterial strain. She found that Compound Z was a potent inhibitor of an enzyme essential for DNA replication. In subsequent tests, however, when the scientist incubated bacterial cultures in media containing high concentrations of Compound Z, she observed no effect on the bacteria. Pose a scientific question the scientist might use to pursue additional research on this topic.
The scientific question I will pose is "what is the effect of concentration on enzyme activity?"
What is the effect of concentration on enzyme?Enzymes are proteins that takes part in chemical and biological reactions without being destroyed at the end of the reaction.
The factors that affect the efficacy of enzymes include the following:
Temperature,pH andConcentration.From the experiment carried out by the microbiologist, the enzyme Compound Z was found to be a potent inhibitor of another enzyme in bacteria which is essential for DNA replication.
When the concentration of this enzyme ( compound Z) was increased, it had no effect on the bacteria enzyme.

1. how does gas compress into liquid in a gas barrel
2. how does gas change back into gas when it exits the barrel
Answer:
1. When a gas barrel is filled with gas, the gas is compressed into liquid form. The compression process takes place when the gas is compressed by the weight of the gas above it. This compression process causes the gas to become liquid.
2. Once the gas leaves the barrel, it returns to its gaseous form. This change back to gas occurs because the pressure on the gas is released when it exits the barrel. This decrease in pressure causes the gas to expand and return to its gaseous form.
What is compression?
Compression is the process of squeezing together. It often refers to the process of reducing the volume of something, or making it smaller.

Burns of the third degree destroy the epidermis and dermis, two complete layers of skin, as well as the fat layer that sits underneath the dermis.
Define third degree burn.Full-thickness burns, commonly referred to as third-degree burns, are a type of burn that not only damages the skin but also the underlying tissue. Since they are more severe than first- or second-degree burns, they always require skin transplants.
Third-degree burns are a dangerous injury that needs quick medical intervention. In contrast to less severe burns, which can be agonizingly painful, full-thickness burns may not ache. This is because burns have the ability to damage skin nerve endings that sense pain.
Additionally, it's possible to see the burn spot.

Some molecules are too large to pass through the cell membrane without the assistance of a protein channel. The process of molecules traveling along their concentration gradient through protein channels is called facilitated diffusion.
The process of spontaneous passive movement of molecules or ions across a biological membrane by particular transmembrane integral proteins is known as facilitated diffusion.
A form of passive transport is facilitated transport. In contrast to simple diffusion, where substances flow across a membrane without the aid of membrane proteins, substances diffuse across the plasma membrane with the aid of membrane proteins in assisted transport, also known as facilitated diffusion.
Facilitated diffusion is significant because it controls what enters and exits the cell. The cellular component that controls the selective transport of chemicals is the plasma membrane. Facilitated diffusion is illustrated by the movement of amino acids and glucose into cells from the circulation.

Describe the three patterns of communication
The three patterns of communication include:
Verbal CommunicationThe most evident kind of communication would appear to be verbal communication. It makes use of spoken language, either in-person or over the phone. Although most encounters need verbal communication, there are other nonverbal indicators that can add to the meaning of the words themselves. A more sophisticated message is conveyed when spoken language is combined with nonverbal communication.Non-verbal CommunicationThe use of body language might reveal some information about a speaker's word choice. It can reflect sarcasm, complacency, dishonesty, or sincerity. Body language, including the speaker's posture, hand gesture, facial expressions, and even look, is a common way to communicate these things. A untidy speaker with wrinkled clothes and slouching posture, for example, might convey a lack of assurance or knowledge. Visual Communication Signs, maps, and drawings, as well as color and graphic design, are all examples of visual forms of communication. These frequently support verbal communication and aid in proving a point. Visual aids can aid in the presentation of the message by helping the speaker remember key points, providing the audience with something to look at, and more.Learn more about communication here:

When lan connects the wires to the battery, an electric current passes through the wire and the bell rings.
What is transferred by the electric current?
OA. force
OB. sound
OC. light
OD. energy
Energy is transferred by the electric current.
Any movement of subatomic charged particles (such as electrons with a negative charge) or ions (atoms that have gained or lost one or more electrons), holes, or other electric charge carriers (protons with a positive charge), constitutes an electric current (electron deficiencies that may be thought of as positive particles).
The electric current in a wire, where electrons serve as the charge carriers, is a measurement of the amount of charge that moves through any point of the wire in a given amount of time. Electric charge motion is occasionally reversed in the alternating current but not in the direct current. In many situations, the flow of positive charge in an electric circuit is assumed to be the direction of the current, which is the direction that the electrons actually drift in.
An electric current distributes the battery's energy to the elements of the circuit. Nothing in this procedure "uses up" any current. Negatively charged electrons, which are constantly present in the circuit's wires and other parts, are the most common type of moving charged particle.
