Myasthenia gravis is an autoimmune condition in which nerve endings are targeted due to the body produces antibodies against receptors of nicotinic acetylcholine which results in less or no functioning of nerve endings of motor neurons mostly.
Options A, B, and C all three conditions are all due to an increase in muscle movement which is not the case as it causes weakness in the muscles due to less functioning in motor end plates.

Answer:
I think the correct answer is nucleic acid. There four major classes of macromolecules and these are lipids, carbohydrates, proteins and nucleic acids. Among these nucleic acid would best fit the definition. Examples of nucleic acids are DNA and RNA
List the name and functions of the major protein involved in transcription.
Answer:RNA polymerase
Explanation: adds nucleotides to form an mRNA copy from DNA by binding to a promoter sequence at the start of a gene, using the DNA template to synthesise the mRNA, and stopping at a termination sequence
The functions and names include adding nucleotides to form an RNA (RNA polymerase), binding DNA for promoting transcription (transcription factors), and stopping transcription at the termination sequence.
What is transcription?Transcription is the cellular process by which a code in the genetic material (DNA) is passed to another nucleic acid called RNA.
During gene transcription, a fragment of DNA called gene is used as a template to create a messenger RNA.Subsequently, this mRNA is then used as a template to create a protein by a process called translation.In conclusion, the functions and names include adding nucleotides to form an RNA (RNA polymerase), binding DNA for promoting transcription (transcription factors), and stopping transcription at the termination sequence.

Which animal is likely to have the highest basal metabolic rate (oxygen consumption per unit body mass)?
Answer:
Hummingbirds
Explanation:
The animal which is likely to have the highest basal metabolic rate (oxygen consumption per unit body mass) Is the Hummingbird.
The hummingbird have a very small mass when compared to other animals or humans but they perform a lot of activities which is also the main reason why they consume volumes of nectar which is proportional to its size.

What can you conclude about the structure of mitochondria?
Answer:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Explanation:

Unlike other careers in neurology, all doctors of neurology who want to apply for work in the US must first go through
certification.
licensing.
training.
a background check.
The correct answer is B. Licensing.
Explanation
The Neurologist is a doctor who has specialized in the study of diseases and disorders that affect the nervous system. When a person in the United States wishes to practice as a neurologist, they must follow some steps. You must first prepare to enter medical school by studying an area related to medicine such as chemistry, physics, biology, among others, which conceptually prepares you for the next step. In the second step, you must apply to medical school, where you will be put to the test with the Medical College Admission Test (MCAT) to measure your knowledge on this subject. Once you enter medical school, there you will learn for two years everything related to the necessary concepts and theory about medicine and later you will have to serve as a medical apprentice in university hospitals where you will apply what you learned.
Third, once the doctor has obtained his title that accredits him as a doctor, he must obtain one of the medical licenses that USMLE (United States Medical Licensing Examination) or COMLEX (Comprehensive Osteopathic Medical Licensing Examination of the United States ) doctors must have in the United States. Finally, the doctor must serve for three years as a resident in a hospital focused on an area related to Neurology and one more year of internship. According to the above, the correct answer is B. Licensing.

1. One positive use of viruses is their function as a. infectious particles. c. cloning vectors. b. pandemic initiators. d. marine predators.
Answer: The correct option is C.
Cloning vectors.
Explanation:
Viruses are use as cloning vectors because they can give the new gene or birth the new gene by infecting the cell. They are so modified and orogrammed in such a way that they cannot cause disease when it is used in humans. Cloning vector is a DNA fragment gotten from viruses or bacteria plasmid which is maintained and used for cloning purposes.
A human skin cell is observed. It is found to have two distinct nuclei each having 46 unreplicated chromosomes. These observations would be seen if the cell is in____.
a. G2 of interphase
b. metaphase of mitosis
c. S of interphase
d. telophase of mitosis
e. prophase of mitosis
Answer:
c
Explanation:
During the telophase stage of mitosis, a cell is observed with two distinct nuclei with 46 unreplicated chromosomes. Thus, the correct option is D.
What is Mitosis?
Mitosis is the process of cell division by which a cell replicates its chromosomes (genetic material) and then segregates that into two daughter cells, producing two identical nuclei in preparation for the division of cell. Mitosis is followed by equal division of the cell's content into two daughter cells with the identical genomes.
During the telophase stage of cell division, the spindle fibers attached to chromatids disappear. Once the daughter chromosomes arrive at the poles, a nuclear envelope starts reappearing around each set of chromosomes. And, at the end of telophase stage of mitosis, there are two nuclei in one cell, known as daughter nuclei that contains an exact copy of chromosomes.
Therefore, the correct option is D.

Explain the relationship between DNA sequence, amino acid sequence, and protein structure and function.
Answer:
The sequence of DNA may be associated with the sequence of amino acids, and the sequence of amino acids to the three-dimensional shape of the protein. It is the sequence of DNA, which provides the code for the amino acid sequence, and the sequence of amino acids further determines the protein structure that further influences the function of the protein.
When the sequence of DNA changes it causes a change in the sequence of mRNA, further resulting in the change in the sequence of DNA's nucleic acid and the sequence of amino acid. The sequence of amino acids of a protein is accountable for the composition of the protein. The composition of a protein is accountable for its function. The function and composition of a protein are primarily accountable for the organism's trait.

What does it mean to be sustainable?
Answer:
To be sustainable is to be able to maintained at a certain rate. It's to keep things continuous and viable. For example, wind energy is sustainable compared to oil because wind is easier to get than oil. Another example is if a country only has about 10-13 crimes a year for 20 years, crime is sustainable in that country.
Define photosynthesis, cellular respiration,
autotroph, heterotroph, herbivore, carnivore,
omnivore
Answer: Omnivore is an animal that eats both plants and animals.
Carnivore is an animal that eats only meat. Herbivore is an animal that eats only plants.
Heterotroph is an organism deriving its nutritional requirements from complex organic substances.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
