their ability to become resistant
to antibiotics

Answers

Answer:

Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.

The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

Study the processes that makes cells work

Answers

Answer:

One cell divides into two in a process called mitosis. Mitosis produces two genetically identical “daughter” cells from a single parent cell. Another type of cell division, meiosis, creates four daughter cells that are genetically distinct from one another and from the original parent cell. Only a few special cells can perform meiosis: those that will become eggs in females and sperm in males

Answers

Answer:

4

Explanation:

The statement that is best supported by the image is that species T and species U are related to species X.

What is evolution?

Is the gradual development of new forms of organisms from their ancestral forms.

In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.

Thus, it is correct to say that T and U are related to species X.

However, it is incorrect to say that X evolved later or species U and V evolved from S.

If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.

What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.
circulatory and lymphatic systems
D.

Answers

the answer is A
i dont really know how to explain but this was a queen in my test and this was the right answer

The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

What is the organ system?

The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.

Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

Answers

Answer:

6. Current = 8.33 Amps

7. Energy = 1200 Joules

Explanation:

Given the following data;

6. Power = 1000 Watts

Voltage = 120 Volts

To find the current flowing through;

Power = current * voltage

1000 = current * 120

Current = 1000/120

Current = 8.33 Amps

7. Power = 900 Watts

Time = 45 minutes to hours = 45/60 = 0.75 hours

To find the energy consumption;

Energy = power/time

Energy = 900/0.75

Energy = 1200 Joules

how magnification and resolution affect the appearance of objects viewed under a microscope​

Answers

Answer:

It allows to see objects more clearly.

Explanation:

Magnification and resolution greatly affects the appearance of objects that can be seen under a microscope​ because these two things make the specimen enlarge in size. Magnification refer to the process of enlarging the apparent size of something to see and observe it clearly while on the other hand, resolution is used to see more details about specimen that can be study in the microscope so we can conclude that both magnification and resolution has a great impact on the appearance of objects.
