Answer: Provide support to the body.
Explanation:
The skeletal system is a system which is formed by the bones. The bones are important for the structure and function of the body. The bones are connected with the muscles to allow the movement of the body, and they protect the vital organs like heart, lungs, brains, and others. They provide support to the soft tissues, organs, and muscles of the body. They keep the human body upright. The skeletal system provide shape to the body. It provides support by acting as regions of attachment of soft body parts and muscles.

How would decreasing the pressure affect the equilibrium of this reaction H2+I2》《 2HI
A. All of the molecules would react more slowly,
B. The reaction would remain in equilibrium,
C. Ha and lo would react to produce Hl more quickly
D. HI would react to produce more H9 and le more quickly.
Answer:
Letter B is your answer.
Explanation:
I just got it correct on A P E X
The decrease in pressure for the given chemical reaction would not affect the equilibrium of the reaction. The correct answer is option b. the reaction would remain in equilibrium.
Pressure is defined as the force per unit area applied perpendicular to the surface of an object.
According to Le Chatelier's principle, a decrease in pressure will favor the side of the reaction with more moles of gas. In this reaction:
[tex]\rm H_2+I_2 \rightleftharpoons 2HI[/tex]
There are two moles of gas on the left side of the equation [tex]\rm (H_2\ and \ I_2)[/tex] and two moles of gas on the right side (2HI).
Therefore, a decrease in pressure will not shift the equilibrium towards either the reactants or products, as the number of moles of gas is the same on both sides of the equation. So, option B is the correct answer: the reaction would remain in equilibrium.

Huntington’s disease (HD) is prevalent South Africa. Most of the families with HD have Dutch or British ancestry, which suggests they inherited the European HD allele. HD is believed to have first arrived in South Africa more than 300 years ago when Dutch colonists settled into the Western Cape in the 1600s. Thus, the prevalence of HD in South Africa is the result of the founder effect.
Mutations in the HTT gene cause Huntington’s disease. The HTT gene provides instructions for making a protein called huntintin. This protein plays a role in nerve cells in the brain. The HTT mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with HD, the CAG segment is repeated 36 to more than 120 times. An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntintin protein. This causes the dysfunction and eventual death of neurons in certain areas of the brain. The more repeats, the more serious the disease is.
HD is inherited in an autosomal dominant pattern. There is both an adult onset (after reproductive age) and a juvenile onset pattern. People with adult onset typically have 40 to 50 repeats, while people with the juvenile form tend to have more than 60 repeats. Individuals who have 27 to 35 repeats do not develop HD, but they are at risk of having children who will develop the disorder. As the gene is passed on to offspring, the size of the repeat may lengthen into the range associated with HD.
Predict what will happen to the allele frequencies for Huntington’s disease in South Africa if there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat. Justify your prediction with evidence. Your response should include links to the sources of information gathered.

A. Anorexia
B. Bulimia
C. Obesity
D. Parkinson's
Answer:
B. Bulimia
Explanation:
See below for a description of each case:
Anorexia (also known as Anorexia nervosa) is an eating disorder characterized by abnormally low body weight. It's similar to the starving of oneself to achieve lower weight, but this is unhealthy. It's very common (more than 3 million cases per year in US) and is treatable. This can last for several months or years and is more common in females from ages 18–35.
Some symptoms include:
Extreme weight loss
Thin appearance
Fatigue and insomnia
Bluish discoloration of the fingers
Hair that thins, breaks or falls out
Amenorrhea (absence of menstruation)
Dry or yellowish skin
Dehydration
Bulimia (also known as Bulimia nervosa) is an eating disorder characterized by binge eating, followed by methods to avoid weight gain (ie. vomiting). It's very common (more than 3 million cases per year in US) and is treatable. It can last several years or be lifelong and are more common in females from ages 18–35.
Some symptoms include:
Binge eating
Forceful vomiting
Long-term fear of gaining weight
Overuse of laxatives or diuretics
Use of supplements or herbs for weight loss
Excessive exercises
Stained teeth (from stomach acid)
Obesity is a condition characterized by abnormal or excessive fat accumulation. It's extremely common (more than 3 million cases per year in US) but is treatable. It can last several years or be lifelong. Family history may increase likelihood for some types.
Some symptoms include:
Above average body weight
Sleep apnea- a condition in which breathing is irregular and periodically stops during sleep
Skin problems caused by moisture that accumulates in the folds of your skin
Osteoarthritis in weight-bearing joints, especially the knees
Parkinson's disease is a chronic and progressive movement disorder, meaning it weakens the control of movements of the body over time. It's fairly common (more than 200,000 cases per year in US). There are treatments to manage the condition but there is no known cure. This can last several years or be lifelong. It's more common in 60+ years old males.
Some symptoms include:
Tremors, trembling of hands, arms, legs, jaw and face
Stiffness of the arms, legs and trunk
Slowness of movement
Poor balance and coordination
Speech difficulty

How does the movement, diet, and cellular structure of an organism play a role in classification?
Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.
The lysosomes are the animal cell’s “garbage disposal”, while in plant cells the same function takes place in vacuoles.
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
The chloroplasts, found in plant cells, contain a green pigment called chlorophyll, which captures the light energy that drives the reactions of plant photosynthesis.
The central vacuole plays a key role in regulating a plant cell’s concentration of water in changing environmental conditions. follow me

Organisms that live in the tundra have developed unique adaptations that aid in their survival. Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. It is the largest terrestrial carnivore, but it is also an excellent swimmer that spends much of its time in and near the water hunting its favorite food. It has large paws with small bumps to provide traction as it walks across the ice. Its fur is helpful as camouflage during the winter months, but not as helpful during the summer. Which organism has the adaptations described that enable it to survive in the tundra
Answer: The organism that has the adaptations described that enable it to survive in the tundra is the POLAR BEAR.
Explanation:
ADAPTATION is defined as the process by which an organism becomes fitted to its environment thereby enabling the organism to live successfully and reproduce.
In any population, an organism is able to survive if it has features that help them to fit and compete successfully in that environment.
From the question, a typical example was given concerning the POLAR BEAR (Ursus maritimus) and it's best fitted environment which is the tundra.
The tundra is a type of biome that is treeless marshy vegetation which is composed mainly of dwarf shrubs. It's has a cold climate (Arctic region) with long icy winters and very short summer with an average temperature of 10°C.
Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. These adaptations include:
--> The presence of a thick coat of insulated WHITE FUR: this helps it to survive the cold environment by acting as an effective insulator. The fur is also found at the base of its large paws with small bumps, which protects it against cold surfaces and provides its with a better grip of ice as it walks across it. It also gives it a concealing coloration making it unnoticed while it stalks its prey in the snow. These are the features that enables it survive the terrestrial environment if tundra.
--> it also has some aquatic adaptations which enables it to hunt it's favourite food which is seals. The presence of large front paws which are slightly webbed allows them swim for a long distance in search of food.
