Answer: Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
Explanation:
Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
The answer to the biology question being presented above would be 'sexual reproduction'. Genetic variability is the most important result of sexual reproduction. In this variability, the genes are varied through sexual union and reproduction.
Answer: The RNA strand is AUAAUCGGUCGCG
Explanation: The nucleotide sequence of RNA has four bases namely: Adenine A, Uracil U, Guanine G and Cytosine C. DNA nucleotide sequence has four bases namely: Adenine A, Thymine T, Cytosine C and Guanine G. In RNA, A pairs with U, and C pairs with G. In DNA, A pairs with T and C pairs with G.
Answer:
C: Fire
Explanation:
Natural and anthropogenic (caused by human) fires could lead to destruction of existing climax community. This leaves the habitat open for the secondary succession where a pioneer species can enter. Lava flow and wind are the natural cause of succession while over-cutting of trees is its human cause.
Answer:
Given that a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two calorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading.
Though consistent, the first colorimeter has a zero error of -5.
Hence whenever first calorimeter is used this adjustment to be made i.e. actual reading +5 should be made to get correct reading
But second can be used as such taking the reading as correct.
