Is autism more common in a certain group of people?
Inessa [10]

Answer:

Explanation:

# Boys are four times more likely to be diagnosed with autism than girls.

# Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.

# 31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85).

# Autism affects all ethnic and socioeconomic groups.

# Minority groups tend to be diagnosed later and less often.

# Early intervention affords the best opportunity to support healthy development and deliver benefits across the lifespan.

# There is no medical detection for autism.

There is usually a food pyramid so for example you could display it along the lines of 1,000 worms are eaten by 20 sparrows which are eaten by 1 eagle. Its just the way things are. It is a fine balance. if you went up to two eagles on same land they would run out of food quickly and then would either starve or have to move on and using up all the food doesnt help them so it needs to be in a fine balance.

An intestinal hormone that stimulates the release of insulin from the pancreatic islet cells is?
slava [35]

Secretin is a hormone produced in the intestines that promote the release of insulin from pancreatic islet cells.

Discussion about secretin:

  • When fatty acids and acidic chyme are present, secretin is released. It performs a number of functions by attaching to secretin receptors, the majority of which are related to digestion and acid neutralization.
  • In its principal function, secretin tells the pancreas to release bicarbonate ions into the pancreatic juice, raising the pH to between 8 and 8.3 in order to neutralize the acidic chyme. The pancreatic juice's digesting enzymes may function at their best as a result, safeguarding the duodenum's lining.
  • Additionally, secretin controls the pyloric sphincter's tightness, gastrin release, HCl synthesis, and small intestine motility.

As a result, secretin also encourages the pancreas to produce more insulin in response to ingesting glucose.
