If some bacteria are resistant to tetracycline and some are not resistant, what happens when a patient is given tetracycline for an infection?

Answers

Answer:

Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

A. uses electricity
B. specimens cannot be alive
C. lower magnification power
D. more expensive to purchase and operate

Answers

Answer:

Explanation:

The drawback or disadvantage associated with the use of light microscopes over electron microscope is its lower magnification power.

LIGHT MICROSCOPE:

Light microscope is a type of microscope in which photons of light is used to view specimens.

The light microscope is distinct from the electron microscope being that electron microscope uses beam of electrons instead.

One advantage of light microscope is that it can view specimens alive while electron microscope can only view dead specimens.

However, one disadvantage associated with the use of light microscope is that it possesses a lower magnification compared to electron microscopes.

when are chromosomes (dna) copied?

Answers

Answer:

Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.

Have a good day. :)

Answer:

Chromosome replication

Explanation:

Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.

Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories

Answers

Answer:

D. 367

Explanation:

If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.

What is food energy?

Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

To find the total calories, multiply the given biomolecules grams with their calorie count.

= 42 × 4 + 7 × 9 + 34 × 4

= 168 + 63 + 136

= 367 calories

Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

the process which takes place in guard cells but not in other epidermal cells is?

Answers

Answer:

guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck

Photosynthesis

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.

Difference in guard and epidermal Cells:

Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.

Photosynthesis does not take place in epidermal cell because:

The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

3. Which of the following statements best explains how the cell membrane 1 point
is selectively permeable? *
The movement of specific substances into and out of the cell is controlled by the cell
membrane
The movement of waste substances into, but not out of the cell is controlled by the
cell membrane
The cell membrane is inflexible and cannot control the movement of substances into
and out of the cell
The cell membrane does not surround the cell so it plays no role in the movement of
substances

Answers

Answer:

The movement of specific substances into and out of the cell is controlled by the cell membrane.

Explanation:

The cell membrane is permeable, so it allows for the passage of substances both into and out of the cell. It is also selective, so only specific substances can enter and exit the cell.

Explanation:

The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection according to Darwin's (and Wallace's) theory of evolution.

Natural selectionNatural selection is the process through which populations of living organisms adapt and change.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation.

Thus, we can conclude that The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.

What is the difference between mold and cast fossils? A Mold fossils fom from collected minerals and cast fossils do not B. Mold fossils are impressions intock and cast fossils fomm from minerals filling molds cast fossils are impressions Into rock and mold fossils form from minerals filling casts Cast fossils are formed in sedimentary rock but mold fossils are not

Answers

I believe the answer is B.

when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil.

How do ocean currents affect the coastal regions of S.America at 20 degrees south latitude

When a lake freezes over. How does the energy content of the lake change?

Answers

Answer:

Explanation:The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies

Question: How do ocean currents affect the coastal regions of S.America at 20 degrees south latitudeAnswer: Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal regionQuestion: When a lake freezes over. How does the energy content of the lake change? Answer: Liquid water has more energy than frozen water. When water freezes it gives up some of the water's energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released(WATER IS THE LAKE)Bonus: I know that during melting, there is no temperature change as the heat energy is used to do work against potential bond energy but why doesn't temperature change when freezing? Freezing is the opposite process of melting. If the temperature does not increase as the ice melts, the temperature will not decrease as water freezes. Melting and freezing are entropy changes. Entropy measure the amount of disorder in a system. A system, like ice, which has less freedom of motion, has less disorder. A system, like liquid water, which has more freedom of motion, has more disorder. So water has more entropy than ice. Ice is a very ordered arrangement of H2O molecules in a crystalline form. As heat energy is added to ice, the energy is used the break the bonds between the H2O molecules in the ice crystals. So, the temperature remains constant. You might say that the energy that is added to the ice is used to increase the entropy of the system, instead of increasing the temperature of the system.-TAY brainly please
