The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?

Answers

Answer:

10.5minutes

Explanation:

DRT = 90%

Cells present = 10^6

Autoclaving = 1.5 minutes

Solution:

10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

What evidence supports the LAW OF CONSERVATION OF ENERGY?
1. Mechanical energy is converted to chemical energy during photosynthesis
2. Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis
3. Oxygen is made from the breakdown of carbon dioxide during photosynthesis
4. The sun gives off light energy that is absorbed by plants

Answers

The evidence that supports the law of conservation of energy is as follows: mechanical energy is converted to chemical energy during photosynthesis.

LAW OF CONSERVATION OF ENERGY:The law of conservation of energy states that energy can neither be created nor destroyed but is changed from one form to another.

This means that energy involved in chemical reactions and natural phenomena is recycled by transformation and doesn't get destroyed.

A typical example that obeys this law is photosynthesis, which converts mechanical energy in sugar molecules to chemical energy in ATP.

An experiment is designed to study the mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and the pH of the solution is monitored. Samples of the cells are taken at intervals, and their sucrose concentration is measured. The pH is observed to decrease until it reaches a steady, slightly acidic level, and then sucrose uptake begins. Rank the steps from first to last. To rank items as equivalent, overlap them.


A proton Pump, using ATP, pumps protons outside.

Sucrose moves into the cell.

A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.

pH decreases;

The gradient becomes sufficient.

H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.

Explanation:

A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.

A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.

The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease

At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.

H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.

A) A proton Pump, using ATP, pumps protons outside.

D) A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.

F) The gradient becomes sufficient.

A co-transporter also called a symporter, is a carrier protein that transports a solute and an ion from one side of the membrane to the other at the same time.

The proton pump is an integral protein that builds a proton gradient across a biological membrane.

The cell cannot import sucrose by simple diffusion, the cell expends energy to move the substance against a concentration gradient.

The sodium and potassium maintain the electrochemical gradient of living cells, the direction an ion moves across a membrane is determined by the electrochemical gradient.

Hydrophilic areas are attracted to water.

Hydrophilic regions of the protein are attracted to other hydrophilic regions.

Explanation:

Proteins are made up of amino acids. The side chains of these amino acids determine whether they are polar or non-polar.  Hydrophilic amino acids are the types that are soluble in water and their side chains are polar. They are attracted to protein parts that are water-soluble.  Examples are Glutamate and Lysine.

The hydrophobic amino acids have non-polar side chains. They withdraw from water by taking on an oily form.  They are attracted to parts of the protein that are not aqueous. Examples are Valine and Tyrosine.

Given what you learned about how influenza changes over time, how could you explain the emergence of drug resistance in bacterial pathogens?

Answers

Answer:

Beneficial mutations events can generate resistance to drugs

Explanation:

Bacteria can develop antibiotic resistance through mutations, as well as horizontal transference events, that allow them to reduce/eliminate the effectiveness of drugs used to treat infections. For example, penicillin-resistant strains have been identified in Staphylococcus aureus and Streptococcus pneumoniae. In general, mutations have a negative impact on the fitness of the organism; however, there are cases where mutations increase the fitness of the individual. In consequence, antibiotic resistance may occur by natural selection, where antibiotic-resistant bacteria that exhibit beneficial mutations are selected to survive and perpetuate their genetic material.

Identify the incorrect statement about a single motor unit. Identify the incorrect statement about a single motor unit. Some motor units include as many as 2000 muscle fibers. Fine motor skills depend on the development of small motor units. The more neurons involved, the more powerful the contraction. The smaller the number of muscle fibers, the more precise the movement. Muscle fibers of one motor unit intermingle with the fibers of another motor unit.

Answers

Answer:

The more neurons involved, the more powerful the contraction

Explanation:

The motor unit can be defined as the functional unit for muscle contraction, which consists of a motor neuron and the associated muscle fibers it innervates. The number of associated muscle fibers varies depending on the muscle’s ability for contraction. Muscles with a higher number of motor units can modulate force output more finely. The number of muscle fibers per motor unit is inversely proportional to the force that it generates, and while higher is precision, lesser is the size of the motor unit. A higher number of neurons is required for controlling motor units with lesser size, thus being greater the brain's control over the extent of shortening.

The incorrect statement about a single motor unit is that some motor units include as many as 2000 muscle fibers. The correct option is A.

One motor neuron and the muscle fibres it innervates make up a motor unit in most cases. Although a motor unit's muscle fibre count might vary, it is normally significantly lower than 2000.

Depending on the muscle and its purpose, the number of muscle fibres in a motor unit might range from a few to several hundred.

Smaller motor units are linked to more precise motions, whereas larger motor units are in charge of more strong contractions. The size of the motor units affects the level of control and precision of movement.

Thus, the correct option is A.

Answers

Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
