Where does the majority of the chemical digestion of protein occur?.
The majority of the chemical digestion of protein occur in small intestine in presence of pancreatic enzyme.
Why is protein digested in small intestine?A necessary nutrient for practically every aspect of your body is protein. Before being released into your bloodstream as individual amino acids, it is digested in your mouth, stomach, and small intestine.
Once a protein source enters your stomach, it is broken down into smaller chains of amino acids by hydrochloric acid and proteases enzymes. Peptides, which are dismantled by proteases, are what connect amino acids together.
The majority of protein digestion takes place in the small intestine, where the chyme travels after leaving the stomach. More enzymes are present in the digestive juices that the pancreas secretes into the small intestine, which will further break down polypeptides.

Which was Charles Darwin’s contribution to the study of biology?
He was the first person to recognize that organisms change over time.
He believed that organisms adapted through the inheritance of acquired traits.
He explained how traits are passed from parents to offspring.
He proposed that natural selection is the primary mechanism of evolution.
Answer:D
Explanation:
Charles Darwin's most significant contribution to the study of biology was his proposal of the theory of natural selection as the primary mechanism of evolution. In his book "On the Origin of Species," published in 1859, Darwin presented a substantial body of evidence showing that species change over time and that natural selection, acting on variations within populations, is the main cause of evolutionary change. Hence option D is correct.
What is Natural selection?Natural selection is a mechanism of evolution that occurs when individuals with certain heritable traits are more likely to survive and reproduce than those without those traits. This results in a gradual change in the characteristics of a population over time.
The process of natural selection occurs because of variation within a population. Individuals that possess traits that are advantageous in their particular environment, such as better camouflage, faster running speed, or stronger immune systems, are more likely to survive and produce offspring that inherit those beneficial traits.
On the other hand, individuals with traits that are less advantageous are less likely to survive and pass on their genes to the next generation.
Although Darwin did propose the idea of inheritance of acquired traits, he later recognized that this mechanism was not significant in evolution. Darwin's work was a significant turning point in the study of biology, and his theory of evolution by natural selection has since become the foundation of modern biology.
Hence option D is correct.

Exposure to toxins can affect a cell's homeostasis and energy production. Cells exposed to toxins will most likely-
Answer:
When toxins damage your enzymes, they prevent the production of hemoglobin in your blood, which can accelerate aging. It also can lead to the failure of energy production and lower your protection against oxidated stress. Failure of these normal body functions increases your risk of diseases like: Cancer.
Explanation:
Toxins modify gene expression. Our genes switch off and on to adapt to changes in our bodies and the outer environment. But many toxins activate or suppress our genes in undesirable ways. Toxins damage cell membranes so they don't respond properly.

Water stress occurs when the demand for water exceeds the supply. This is likely to occur in:
Question 19 options:
Rainforest, small towns, industrial areas
Wet ecosystems, Sparsely populated Countries, less intense agriculture
Naturally arid ecosystems, Heavily populated countries, Areas with intensive, highly-irrigated agriculture
Tundras, medium populated countries, cattle-farming
Answer:
C. is the correct answer!
Explanation:
If its a naturally arid ecosystem then there wouldn't be that much water there in the first place.
The more people means the more supplies its needed to support those people, which can also lead to supply shortages such as in water.
Highly irrigated agriculture can also lead to tons of water being wasted, needed, and used up.
