Q: What term describes a region of space around an atom that has a non-zero probability for an electron with a particular energy? Read this paragraph and choose the correct option from the provided answers: An atomic orbital is a region of space around an atom that has a non-zero probability for an electron with a particular energy. Analogously, a molecular orbital is a region of space in a molecule that has a non-zero probability for an electron with a particular energy. Both an atomic orbital and a molecular orbital can contain two electrons. Choices: - orbital lobe - minimal orbital - related orbital - atomic orbital A:
atomic orbital

Q: What is the transfer of information from rna to dna called? Read this paragraph and choose the correct option from the provided answers: Reverse transcription is the transfer of information from RNA to DNA. The is the reverse of normal transcription. Reverse transcription occurs in retroviruses, such as HIV, the virus that causes AIDS. Retroviruses are RNA viruses that are duplicated in a host cell by using reverse transcriptase enzyme to produce DNA from its RNA genome. Choices: - confront transcription - forward transcription - reverse differentiation - reverse transcription A:
reverse transcription

Q: Q: What are scientists called who study the weather and give forecasts? Read this paragraph and choose the correct option from the provided answers: People often complain when the weather forecast is wrong. Weather forecasts today, however, are much more accurate than they were just 20 years ago. Scientists who study and forecast the weather are called meteorologists. How do they predict the weather?. Choices: - climatologists - geologists - botanists - meteorologists A:
A: meteorologists

Question: Q: What do you call the strands of dna wrapped around proteins, which are located inside the nucleus? Read this paragraph and choose the correct option from the provided answers: Inside of the nucleus, you will find the chromosomes . Chromosomes are strands of DNA wrapped around proteins. They contain genes , or small units of genetic material (DNA) that contains the code for the creation of a protein. Human cells have 46 chromosomes (23 pairs). There are hundreds to thousands of genes on each chromosome. Choices: - receptors - ribosomes - fibrils - chromosomes A:
Answer: chromosomes

*Question*
Q: Predators can replace what tool in agriculture. Read this paragraph and choose the correct option from the provided answers: Predator species such as birds and spiders control insect pests. They reduce the need for chemical pesticides, which are expensive and may be harmful to human beings and other organisms. Choices: - harvesters - fertilizer - irrigators - pesticides A:
**Answer**
pesticides

Q: Q: All proteins are made of monomers called what? Read this paragraph and choose the correct option from the provided answers: Proteins are molecules that have many different functions in living things. All proteins are made of monomers called amino acids ( Figure below ) that connect together like beads on a necklace ( Figure below ). There are only 20 common amino acids needed to build proteins. These amino acids form in thousands of different combinations, making about 100,000 or more unique proteins in humans. Proteins can differ in both the number and order of amino acids. It is the number and order of amino acids that determines the shape of the protein, and it is the shape (structure) of the protein that determines the unique function of the protein. Small proteins have just a few hundred amino acids. The largest proteins have more than 25,000 amino acids. Choices: - monotides - aminotides - peptides - amino acids A:
A: amino acids
