Salivary amylase is an enzyme in humans that breaks down starches. What substances would humans have difficulty digesting without this enzyme
Group of answer choices
Answers
Answer:
Carbohydrates
Explanation:
High in fats and very fatty
In the absence of salivary amylase, humans would have difficulty digesting carbohydrates.
What is salivary amylase?Salivary amylase is produced by the salivary glands located towards the back of our mouth. Salivary amylase is a very small percentage of the total amount of amylase produced by the body.
Most of the amylase in the body is secreted by the pancreas. Salivary amylase is secreted in the saliva. This begins the process of the breakdown of food in the mouth itself.
Salivary amylase breaks down carbohydrates into maltose units which is a disaccharide. The maltose is ultimately broken down into glucose.
Carbohydrates are a very significant portion of the diet of a large percentage of the global population. Various kinds of bread and rice have a large portion of them composed of carbohydrates.
Therefore, in an absence of salivary amylase, humans would have difficulty digesting carbohydrates.

What force is present at a divergent boundary?
A. Shearing
B. Torsion
C. Tension
D. Compression
Answers
Tension force is present at a divergent boundary. Therefore, option (C) is correct.
What do you mean by tension force?Tension is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
Tension formula is articulated as. T=mg+ma. Where, T= tension (N or kg-m/s2) g = acceleration due to gravity (9.8 m/s2)
All physical objects that are in contact can exert forces on each other. We give these contact forces different names based on the types of objects in contact. If one of the objects exerting the force happens to be a rope, string, chain, or cable we call the force tension.

Answers
Answer:
Yes.
Explanation:
If the graph line comes lowers from 1999 to 2013 so it means that steps taken by the EPA and the factories were effective in reducing air pollution. The steps taken by the EPA and the factories were effective in reducing air pollution occurs from two pollutants i. e nitrogen oxides (NOx) and sulfur dioxide (SO2) if they install chimneys which collect these gases and reduce pollution. if the factories uses coal having less concentration of sulphur so less air pollution occurs.
Answer:
Yes, the steps taken by the EPA and factories were effective in reducing air pollution from NOx and SO2 because the emissions of these two pollutants have decreased over the years.

What kind of adaptations could have given homosapiens an evolutionary advantage over neanderthals and other species of humans?
Answers
Answer:
humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations
Explanation:
A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.
