Autism Spectrum Disorder is a neurodevelopmental disorder that affects a person's social communication, behavior, and interaction.

The term “spectrum” indicates that symptoms and severity can differ from person to person. The intensity of symptoms is what differentiates ASD from one individual to another. Even though all individuals with (ASD) Autism Spectrum Disorder share certain challenges, ASD affects each person differently. Consequently, some individuals may require significant support, while others may need minimal assistance. ASD is typically diagnosed in early childhood, but symptoms can be identified as early as 18 months. While there is no cure for ASD, early intervention and therapy can help individuals with ASD improve their social and communication skills and manage challenging behaviors.

True, mental rotation activates similar brain regions as performing a physical rotation.

Mental rotation and physical rotation have been found to activate similar brain regions. Studies using neuroimaging techniques such as functional magnetic resonance imaging (fMRI) have shown that both mental and physical rotation tasks activate the parietal cortex, which is involved in spatial processing and the manipulation of mental images. These findings suggest that mental rotation is not just a cognitive process but also involves the same neural mechanisms as physical rotation.

Physical rotation refers to the actual movement or turning of an object or body part, such as turning a key in a lock or rotating the arm at the shoulder joint.

The correct answer to the given question is vitamin E works in the lipid membrane and vitamin C works in the aqueous solution of the cell.

So, the answer is C.

Vitamin E is a fat-soluble nutrient that serves as an antioxidant in the body. Vitamin E, like all antioxidants, aids in the body's battle against harmful, unstable particles known as free radicals. Furthermore, vitamin E has been linked to a variety of other health benefits, such as reduced cholesterol levels and reduced skin aging. Vitamin E is abundant in nuts, seeds, and vegetable oils.

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that acts as an antioxidant in the body. Vitamin C aids in the protection of cells against oxidative stress, which is caused by free radicals. Vitamin C also helps to regenerate other antioxidants in the body, such as vitamin E. Vitamin C is found in citrus fruits, strawberries, kiwi fruit, bell peppers, broccoli, spinach, and other vegetables.

A lipid membrane is a double layer of lipids, or fat molecules, that surrounds a cell. The lipid bilayer serves as a barrier that allows only certain molecules to enter and exit the cell. The lipid membrane, for example, prevents toxic substances from entering the cell while allowing necessary nutrients to enter the cell for survival.

Answer: Brain

Explanation:

The correct answer about mRNA is (d). The researcher will find that the molecule is digested by enzymes because it is not protected at the 5' end.

The cap structure is a methylated guanine that links to the mRNA via an unusual 5' to 5' triphosphate bond, while the poly-A tail is a series of adenines that are added to the 3' end of an mRNA molecule. The cap and tail are vital for ensuring mRNA stability, mRNA nuclear export, and translation initiation into proteins. When the cap and tail are removed, the mRNA becomes vulnerable to RNases (ribonucleases), which are enzymes that digest RNA.

In summary, the mRNA will not be translated by a ribosome because it lacks a 5' cap, which is required for translation initiation, and it will be rapidly degraded by enzymes because it lacks a poly-A tail.

The researcher would thus expect the mRNA to be destroyed quickly.

Many of the health problems of older adults are chronic rather than acute. A concern regarding the medical system is that: the medical system is still based on a "cure" rather than a "care" model. The correct option is C.

It means that the healthcare system tends to focus on treating acute illnesses and injuries rather than managing chronic illnesses. The emphasis is on treating the patient with drugs or surgery to cure their illnesses, rather than providing ongoing care to manage the disease.

Medicare does not have special provisions for chronic illnesses, which can leave elderly patients with significant out-of-pocket expenses for long-term care. As a result, many elderly individuals with chronic illnesses have difficulty accessing the care they require. The costs of prescription drugs are still not subsidized for the elderly.

Many elderly individuals require a variety of medications to manage their chronic conditions. However, these drugs can be quite costly, and many individuals struggle to afford them. Home visits are not emphasized over hospital stays. Hospital stays can be disruptive to the lives of elderly individuals and can also be expensive.

The normal approximation to the binomial distribution is given as:

X ~ B(n, p), then it is approximated to a normal distribution such that,

X ~ N(np, np(1-p)) where n is the number of trials, p is the probability of success, and (1-p) is the probability of failure.

The null hypothesis is given as H₀: The median percent of impurities in this brand of jam is 25%.

The alternative hypothesis is given as H₁: The median percent of impurities is not 25%.

The median percent of impurities is given as : (1/2) * (16 + 1) = 8.5.

The following are the number of times the data is above and below 8.5: 2.4 + 2.3 + 3.1 + 2.2 + 2.3 + 3.6 = 16.9 > 8.5. Thus, we have 6 values above the median.

1.2 + 1.0 + 1.7 + 1.9 + 1.6 + 2.3 = 10.7 > 8.5. Thus, we have 6 values below the median.

The total number of signs of observations above the median is given as m₁ = 6.

The total number of signs of observations below the median is given as m₂ = 6

The total number of observations is given as n = 16.

The Z test statistic is given as Z = [min(m₁, m₂) - 0.5]/[√(n/2)] = [min(6, 6) - 0.5]/[√(16/2)]≈ 1.5

Using a normal distribution table, the critical value for α = 0.05 is given as zα/2 = 1.96.

Since |Z| = |1.5| < |1.96|, we accept the null hypothesis that the median percent of impurities in this brand of jam is 25%. Therefore, the sign test at the 0.05 level of significance is not significant enough to reject the null hypothesis.
