Answer the following question given this paragraph: Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color. Q: What is the term for traits that show wide variation, such as height, skin color, and eye color? Choices: - maladaptive traits - inherited traits - recessive traits - polygenic traits A:
polygenic traits
Answer the following question given this paragraph: Living things are made of matter. In fact, matter is the "stuff" of which all things are made. Anything that occupies space and has mass is known as matter. Matter, in turn, consists of chemical substances. A chemical substance is a material that has a definite chemical composition. It is also homogeneous, so the same chemical composition is found uniformly throughout the substance. A chemical substance may be an element or a chemical compound. Q: What is the 'stuff' that all things are made of? Choices: - minerals - metal - plasma - matter A:
matter
Q: Answer the following question given this paragraph: A carrier protein is a transport protein that is specific for an ion, molecule, or group of substances. Carrier proteins "carry" the ion or molecule across the membrane by changing shape after the binding of the ion or molecule. Carrier proteins are involved in passive and active transport. A model of a channel protein and carrier proteins is shown in Figure below . Q: Where do carrier proteins carry ions or molecules? Choices: - between nuclei - across isotopes - back to nucleus - across the membrane A:
A: across the membrane
Question: Answer the following question given this paragraph: 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. Q: All proteins are made of monomers called what? Choices: - monotides - aminotides - peptides - amino acids A:
Answer: amino acids

Answer the following question given this paragraph: The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms. Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb. Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere. Q: The nitrogen cycle moves nitrogen back and forth between the atmosphere and what? Choices: - Ocean - Ozone Layer - sediments - organisms A:
**Answer**
organisms
