an individual with the condition of myasthenia gravis is faced with an autoimmune disorder in which the body defenses attack acetylcholine receptors on muscle cells. what would be the expected effect on calcium levels near contractile proteins, following the arrival of an electrical impulse at those neuromuscular junctions?
When acetylcholine binds to its receptor, the muscle is stimulated and contracts. In myasthenia gravis, immune proteins called antibodies block, alter, or even destroy acetylcholine receptors at the neuromuscular junction, preventing the muscle from contracting.
How does myasthenia gravis develop in relation to the immune system?Myasthenia gravis causes antibodies to be produced by your immune system that either block or harm many acetylcholine receptor sites in your muscles. Because there are fewer available receptor sites, your muscles get fewer nerve impulses, which results in weakening.
Myasthenia gravis (MG) is a long-term autoimmune disorder in which antibodies prevent the nerves' ability to communicate with the muscles, weakening the skeletal muscles as a result. Acetylcholine receptor antibodies are the main cause of myasthenia gravis, a neurological disorder that weakens and exhausts the voluntary muscles.

White blood cells, called leukocytes, are very different in structure and function than red blood cells. White blood cells help fight infections, parasites, and bacteria. They do this by engulfing pathogens and synthesizing antibodies which are made from proteins. In addition white blood, cells can reproduce unlike red blood cells.
Many white blood cells can't divide and they have the ability to reproduce on their own.
How do white blood cells reproduce?White blood cells are not similar to other types of cells that are present in our body. They act like single-cell organisms which can move on their own and can feed on other cells and bacteria. Many types of white blood cells can't reproduce on their own so they are produced in the bone marrow. In a person that has normal bone marrow, the number of white blood cells can double within hours. It is a type of blood cell that is produced in the bone marrow and found in the blood lymph tissue. White blood cells are part of the immune system of our body. White Blood Cell protects Red Blood Cell, as it tries to protect the red blood cells from pathogens.
So we can conclude that the cells which can move freely and feed on pathogens and bacteria that can harm our body are known as white blood cells.

What is the difference between small, controlled lab experiments versus an ecosystem-scale experiment?
The major difference between the small, controlled lab experiments versus an ecosystem-scale experiment is the number of variables.
Experiments are the scientific procedures carried out in order to make some discovery, test any hypothesis or demonstrate or mimic any natural process. Experiment is a step by step process that requires strict conditions.
Variables in an experiment are the factors, characters or some condition that can be changes according to the need or demand of the experiment. There are three types of variables: Independent, Dependent and Controlled.

what is sexual reproduction system
The process of creating new creatures through the union of the genetic material from two individuals of different sexes is known as sexual reproduction.
The majority of creatures have chromosomes, which contain the genetic material, in the nuclei of their reproductive cells, known as gametes, which mate to produce a diploid zygote. The fusion of a haploid female gamete (egg cell) with a haploid male gamete is the process of sexual reproduction.
These gametes combine during fertilization, creating a diploid zygote as a consequence. A unique organism that is genetically separate from its parent species emerges from the zygote. Contrast this with asexual reproduction, in which an organism reproduces without the use of gametes and the progeny are identical clones of the parent.
However, sexual reproduction outperforms asexual reproduction in terms of boosting genetic diversity and enlarging the gene pool. Additionally, it guarantees that a species' chromosomal count will not change over successive generations. The two main methods of sexual reproduction are conjugation and syngamy.
