Answer:
Edrophonium is a drug used for the treatment of myasthenia gravis, a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness, which results from antibodies that block or destroy nicotinic receptors at the junction between the nerve and muscle. By blocking cholinesterase, an enzyme which demolish acetylcholine, it increases the amount of acetylcholine in the neuromuscular junction improving the muscle weakness
It improves Annie's muscle function as a result of the acetylcholine not
being able to be broken down in the muscles.
Acetylcholine is a neurotransmitter that sends signals to the brain and other
parts of the body in the activation of the skeletal muscles.
The drug known as Edrophonium which blocks cholinesterase breaking
down acetylcholine in the muscles will thereby lead to more presence of
acetylcholine and a corresponding increase in the muscle functions.

Answer:
Answer: The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.

Greg Developed and Ear infection. His doctor gave him an antibiotic. The antibiotic killed all the bacteria in his body. What other effect could the antibiotic have
Some of the antibiotics doctors prescribe to treat an ear infection such as amoxicillin, cortisporin (neomycin/hydrocortisone) solution or suspension.
What is infection?The infection is invasion and growth of germs in the body. The germs can be bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin anywhere in the body and may spread all through it.
Antibiotics can have side effects as when children take antibiotics at the first sign of an ear infection, they are more likely to have vomiting, diarrhea, and allergic reactions because of the medicine. Also, antibiotics can kill “friendly” germs in the body and cause other problems like diarrhea.

What are some examples of climatic conditions that support certain species and inhibit others?
Answer:
The cold temperatures, snow and ice, lack of daylight in winter and lack of darkness in winter, make good conditions for the survival of polar bears, seals, caribou, etc., but seriously prohibit the survival of mosquitoes and most other insects.
Explanation: Here's your answer, hopefully this will be help!
The examples of the climatic conditions that support certain species and inhibit others involved the snow, ice, etc.
Examples of the climate conditions:The cold temperature, snow, and ice, absence of daylight in the winter season, and absence of darkness in winter seasons resulted from the polar bears survival.
But at the same time, it restricts the mosquitoes and other insects survival.

29. A teacher presented the two models below to the dass. The models represent a eukaryote and prokaryote cell. The teacher asked the students to label the structure of each cell that contains the genetic code and
tell where it is located.
structure C, located in the cytoplasm in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the nucleus in Cell B
structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the cytoplasm in Cell B
Answer:
C. structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
Explanation:
This question contains images that depicts an eukaryotic cell (animal) and a prokaryotic cell (bacteria). According to the question, a teacher asked the students to label the structure of each cell that contains the genetic code (DNA) and tell where it is located.
In an eukaryotic cell, the genetic material (DNA) which contains the genetic code is located inside a well defined membranous structure called NUCLEUS while the genetic material in a prokaryotic cell is found naked in a region of the cytoplasm called NUCLEOID as they lack a membrane-bound nucleus. Based on this explanation;
- Structure C is the genetic material (DNA) which contains the genetic code of cell A (eukaryotic cell), hence, the genetic code of cell A is found in structure C, which in turn is located in the centrally-placed NUCLEUS.
- Structure C is the genetic material containing the genetic code of cell B (prokaryotic cell), hence, the genetic code of cell B is found in structure C, which in turn is located in the CYTOPLASM.
