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:

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.

The answer is B. Since slavery was introduced to the West Coast of Africa in the 1600s, it became a thriving trade that spurred the industrial revolution. The trans-Atlantic slave trade was used to put slaves on the farms in the Americas. The African leaders benefitted from the sale of Africans as slaves. Powerful kingdoms hence raided weaker tribes to capture slaves for sale to the Europeans.  

According to the text, the growing demand for African slaves during the slave trade era motivated African leader to initiate attacks of rival tribes in order to profit by selling captured Africans to the Europeans.

What is a major reservoir for ammonia?

Answers

Answer:

The major reservoir for Ammonia is the natural soil, where it is present in abundance.

Explanation:

In soil, ammonia is found in quite abundance, where it is changed into nitrate through a process commonly knows as Nitrification. In the nitrification process, first, nitrite is formed which is followed by its conversion into nitrate by a bacteria known as Nitrobacteria. Finally, this nitrate is consumed by the plants, which are then eaten up by the animals.

Final answer:

Ammonia is a crucial compound found variously within the biosphere. In animals, it is processed into safer compounds for excretion, while in the environment, it is both a product of decomposition processes and an important component for agricultural practices.

Explanation:

Ammonia is a nitrogenous compound that plays a significant role in various biological and ecological contexts. In terrestrial animals, the major reservoir for ammonia is the biological system where it is present in compounds such as proteins and nucleic acids. Through the process of metabolism, animals convert the toxic ammonia into urea or uric acid, which are safer for the organism. This is exemplified by the urea cycle in mammals and the corresponding processes in birds, reptiles, and terrestrial arthropods.

Additionally, ammonia is an important product of ammonification, a process that occurs during the decomposition of nitrogen-containing organic compounds. A small percentage of ammonia is also released into the atmosphere.

Furthermore, ammonia is crucial for our economy, particularly in the agriculture industry. It is heavily utilized in the production of fertilizers and also serves as a vital ingredient for the growth of several crops.

A fertile hypha that bears spores is called a?

Answers

a fertile hypha that bears spores is called a sporangiophore. basically, it's a  vertically shaped hypha that hold a chamber filled with the spores, and once it's ready it lets the spores out :)

Don't choose the other answer unless you want to be wrong!

The correct answer is:

conidiophore

This is what the lesson says:

Reproduction among the fungi can occur both asexually and sexually. Asexually, fungi can reproduce by fission, fragmentation, budding, and producing spores. Spores are common reproductive structures among fungi. These spores can be carried by the wind, giving the stationary fungus the ability to spread its offspring over great distances. Molds reproduce by spores. A fertile hypha that bears spores is a conidiophore.

Which of the following is NOT a characteristic of all living things?A. growth and development
B. ability to move
C. response to the environment
D. ability to reproduce

Answers

The answer which is not a characteristic of all living things is B. ability to move.
Just take plants for example - they are indeed alive, but they remain stationary because they do not have the means to move. Every living thing grows and develops, has a certain response to the environment, and can reproduce, in one way or another.
The ability to move because not all living things can move like plants they cannot move but they can respond to their surrounding/ environment, ability to reproduce, and growth and development like all living things do to live/survive
