Explanation:
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
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.

Explanation:
A man suffers a penetrating wound through the anterior axillary fold, with resulting damage to one of the main terminal branches of the brachial plexus. Among the effects is a significant weakening of flexion of the elbow. One or more other effects to be expected is (are):______.
A. Loss of cutaneous sensation on the tips of several fingers.
B. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the forearm.
C. Only weakening of flexion at the shoulder.
D. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the arm.
Answer:
The correct answer is option b. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the forearm.
Explanation:
Brachii and brachialis are the two muscles that are innervated by the Musculocutaneous nerve. These muscles help in the production of the flexion at the elbow, and it is known that the musculocutaneous nerve is damaged due to the penetration through the anterior axillary fold.
Other than these muscles there would be an effect on the nerve that provides sensory signals or information to the anterolateral surface of the forearm, known as the lateral antebrachial cutaneous nerve.
Thus, the correct answer is: option B.

What are the different types of chromosomal abnormalities?Chromosomal abnormalities are of different types; some are related to autosomes, and some are related to X and Y chromosomes. The down syndrome happens due to the trisomy in the 21st chromosome, which means instead of two chromosomes, there are three chromosomes.
In Patau syndrome, the trisomy is seen in the 13th pair of homologous chromosomes, and as a result, instead of two chromosomes, three are present. Klinefelter syndrome is associated with males who have an extra X chromosome. Infertility is observed as a result of this male display of female characteristics, such as behavioral changes. Turner syndrome is associated with females who have lost one X chromosome.
As a result, the correct answer is option D, which is Klinefelter syndrome, which is XXY.

A solution with a pH of 2 can be increased to a pH above 7 by adding
Answer:
an acid
Explanation:
A solution with a pH of 2 can be increased to a pH above 7 by adding base (e.g. sodium hydroxide, potassium hydroxide).
What is a base?Bases are chemical substances that have a pH higher than 7 and that can neutralize acids. They have properties such as a bitter taste, slippery feel, and the ability to turn red litmus paper blue. Bases are classified as either strong or weak, depending on their ionization in solution. Strong bases have a high degree of ionization and can rapidly neutralize acids, while weak bases ionize to a lesser extent and have a slower effect on the pH of a solution.
Bases are important in many industrial and biological processes, and are used in cleaning agents, fertilizers, and medicines. The most well-known base is probably sodium hydroxide, commonly known as lye, which is used in the manufacture of soaps, detergents, and other products. Understanding the properties and behavior of bases is important in many fields, including chemistry, medicine, and environmental science.

Which equation best represents conservation of matter?
A 6H2O + 6CO2 → C6H12O6 + 6O2
B 6H2O + 6CO2 → C3H6O3 + 3O2
C 3H2O + 3CO2 → C6H12O6 + 6O2
D 6H2O + 10CO2 → C6H12O6 + 4O2
Answer:
A 6H2O + 6CO2 → C6H12O6 + 6O2
Explanation:
The law of conservation of matter states that matter can neither be created nor destroyed in a system. In other words, when elemental matter undergoes a reaction, the amount of elements used must be equal the amount produced.
The equations in this question depicts the overall photosynthetic process where CO2 combines with H2O to produce C6H12O6 and O2. In order for this equation to obey the "conservation of matter", each individual element must be equal on both the reactant and the product side i.e. the equation must be balanced.
The equation that fulfills this is:
6H2O + 6CO2 → C6H12O6 + 6O2
Hence, it correctly describes the conservation of matter.

Suppose you have two identical solutions of glucose, A and B. The solutions are separated by a permeable membrane that will allow the movement of both glucose and water. You want to establish a concentration gradient so that more glucose in solution B will move into solution A.
How can you manipulate your experimental setup so that the glucose will move in that direction?
Answer:
Add more water to A
Explanation:
In order to establish a concentration gradient so that more glucose in solution B would move to A, more water would be needed in A.
Adding more water to A will reduce the glucose concentration of A and create a concentration gradient which will allow some glucose molecules to move from B to A in order for equilibrium to be re-established.
