Answer:
Plate Boundaries
Explanation:
Puerto Rico might be on a plate boundary. When two plates slide against each other (also called a transform boundary) they can cause a earthquake to happen on the surface.
<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>
Explanation:
Let us understand the term DDT
DDT : Dichlorodiphenyltrichloroethane
- This is a crystalline chemical compound
- Basically used for protecting insects eating crops
- It is colorless, odorless, tasteless
- Initially used as pesticides
It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.
It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.
It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures
It contained toxins: It contains moderate toxins.
Answer:
C) The water is cooler than the land, and wind blows toward the beach.
Your answer is precipitation: <span>Any or all of the forms of water particles, whether liquid or solid, that fall from the atmosphere (e.g., rain, hail, snow or sleet). It is a major class of hydrometeor, but it is distinguished from cloud, fog, dew, rime, frost, etc., in that it must fall. It is distinguished from cloud and virga in that it must reach the ground.(Grammarly)</span>
Enzymes are typically composed of amino acids.
Enzymes specifically binds to their substrate, and accelerate the biological or in-vitro reactions.
Four real-life examples of enzymes are: Lipase, Maltase, DNA ploymerase and Alcohol dehydrogenase.
Explanation:
All enzymes are proteins. They are composed of amino acids as monomer units linked by polypeptide bonds.
The substrate is a molecule which has specific enzyme binding sites for the highly specific enzyme called as active sites. With this binding, the enzyme-substrate complex is formed, undergoes the chemical reaction and new product is formed. Enzymes accelerate the biological reactions by lowering the reaction's activation energy.
Four-real life examples of enzymes are:
Lipase enzyme: catalyses the hydrolysis of fats and triglycerides in the small intestine. Lipase enzyme is secreted by pancreas.
Maltase enzyme: catalyses the breakdown of maltose sugar. It is secreted by salivary glands and our mouths.
DNA Polymerase Enzyme: It catalyses the DNA replication in the cells. It is secreted by the nucleus
Alcohol dehydrogenase: It catalyses many reactions in the body as the reduction of NAD to NADH. It is secreted by the liver.
