A 68-year-old woman who presents after a fall reports progressive difficulty climbing stairs for the past 3 months. She also feels a loss balance when rising from a chair. She has a 5-year history of diabetes mellitus for which she takes metformin. Examination demonstrates intact cranial nerve function; normal sensory examination except for mildly decreased touch and vibration in her toes, normal motor function except for 4+/5 deltoid power and 4+/5 hip power bilaterally, and an inability to stand on her toes. Deep tendon reflexes are 2+ but 1+ at the ankles; plantar responses are flexor; cerebellar function is normal except for mild difficulty with heel-knee-shin testing. She has difficulty rising from a chair without pushing up with her hands. These clinical findings are best explained by dysfunction in which of the following regions of the nervous system?A. anterior horn cellB. muscleC. nerve plexusD. peripheral nerveE. spinal cord

Answers

Answer 1

Answer:

spinal cord and nerve plexus

Explanation:

Faced with this clinical picture, we would be talking about the affection of the spinal cord and the peripheral nerves that sensually perceive the areas of the epithelium, that is, they give the sense of touch, since the patient is diabetic, it could be deduced that the microangiopathies that this generates Chronic disease over time, can affect the irrigation of certain areas and therefore their inventions, due to lack of supply of oxygen and nutrients.

Diabetics are at risk of affecting both upper and lower limbs, because over time they lose the vascularization and winterization of these areas, thus generating infections or pain imperceptible by the patient.

On the other hand then, it would be ideal to say that the spinal cord with the peripheral nerves that innervate the affected areas, and the cerebellum are affected by the lack of balance or spatial disposition of the patient in relation to their body size.

A student experiments with two solutions containing the same solute concentrations
in a beaker that is divided by a semipermeable membrane, as shown.

In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker

Answers

Answer:

B in both directions at the same rates

Explanation:

Solutions with the same amount of solute concentration is referred to as ISOTONIC. In an isotonic solution, there is NO net movement of water molecules because there is no osmotic gradient i.e. difference in solute concentrations.

In this case, a student experiments with two solutions containing the SAME SOLUTE CONCENTRATIONS in a beaker that is divided by a semipermeable membrane. Due to the equal amount of solute concentrations in both solutions, water moves into and out each membrane at an equal rate.

In order for the concentrations of the solutions to remain constant on both sides of the membrane, WATER MUST MOVE IN BOTH DIRECTIONS AT THE SAME RATE.

Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?

Answers

Answer:

f = 7.87×10¹⁴ Hz

Explanation:

Given data:

Speed of light = 3×10⁸ m/s

Wavelength of light = 3.81 ×10⁻⁷ m

Frequency of light = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

Now we will put the values in formula.

3×10⁸ m/s = 3.81 ×10⁻⁷ m × f

f = 3×10⁸ m/s /  3.81 ×10⁻⁷ m

f = 0.787 ×10¹⁵ s⁻¹

   s⁻¹  = Hz

f =  0.787 ×10¹⁵ Hz

f = 7.87×10¹⁴ Hz

a) Explain why antibiotics would kill a prokaryotic cell. (2 points)

Answers

Answer:

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.

Explanation:

Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.

Gametes is an example of haploid cells.

Explanation:

Haploid cells are cells that contain a single complete set of chromosomes. Haploid cells in humans and other mammals, are usually the sex cells (egg and sperms) which are also called gametes that are produced during meiosis (a type of cell division). When the egg is fertilized by a sperm, it produces a diploid cell. Gametes contain 23 chromosomes in humans.

if a prey evolves to increase its defenses, its predator often evolves to counteract this change. a. True b. False​

Answers

Answer:

a. True

Explanation:  

Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.

What is the role of an enzyme in a reaction with the reaction ? would the reaction happen without an enzyme?

Answers

Answer:

Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.

Explanation:

Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.
