Question: Q: Water follows where sodium ions lead, due to what process?   Read this paragraph and choose the correct option from the provided answers:  Blood Pressure Regulation Due to osmosis, water follows where Na+ leads. Much of the water the kidneys recover from the forming urine follows the reabsorption of Na+. ADH stimulation of aquaporin channels allows for regulation of water recovery in the collecting ducts. Normally, all of the glucose is recovered, but loss of glucose control (diabetes mellitus) may result in an osmotic dieresis severe enough to produce severe dehydration and death. A loss of renal function means a loss of effective vascular volume control, leading to hypotension (low blood pressure) or hypertension (high blood pressure), which can lead to stroke, heart attack, and aneurysm formation. The kidneys cooperate with the lungs, liver, and adrenal cortex through the renin–angiotensin–aldosterone system (see Figure 25.14). The liver synthesizes and secretes the inactive precursor angiotensinogen. When the blood pressure is low, the kidney synthesizes and releases renin. Renin converts angiotensinogen into angiotensin I, and ACE produced in the lung converts angiotensin I into biologically active angiotensin II (Figure 25.23). The immediate and short-term effect of angiotensin II is to raise blood pressure by causing widespread vasoconstriction. angiotensin II also stimulates the adrenal.   Choices:  - electrolysis  - absorption  - hydration  - osmosis   A:
osmosis
Q: What type of tissue makes up much of the inside of a plant?   Read this paragraph and choose the correct option from the provided answers:  Ground tissue makes up much of the inside of a plant. The cells of ground tissue carry out basic metabolic functions and other biochemical reactions. Ground tissue may also store food or water.   Choices:  - leaf tissue  - stem tissue  - working tissue  - ground tissue   A:
ground tissue
Q: Q: What is the name for biochemical compounds that consist of one or more chains of small molecules called amino acids?   Read this paragraph and choose the correct option from the provided answers:  Proteins are biochemical compounds that consist of one or more chains of small molecules called amino acids. Amino acids are the monomers of proteins. There are only about 20 different amino acids. The sequence of amino acids in chains and the number of chains in a protein determine the protein’s shape. Shapes may be very complex. You can learn more about the shapes of proteins at this link:.   Choices:  - lipids  - protons  - hormones  - proteins   A:
A: proteins
Question: Q: Alterations that change chromosome structure are known as?   Read this paragraph and choose the correct option from the provided answers:  Chromosomal alterations are mutations that change chromosome structure.   Choices:  - lesions  - traits  - deformities  - mutations   A:
Answer: mutations

Q: Transparent, translucent, or opaque are properties of matter based on an interaction with what?   Read this paragraph and choose the correct option from the provided answers:  Matter can be classified on the basis of its interactions with light. Matter may be transparent, translucent, or opaque. An example of each type of matter is pictured in the Figure below .   Choices:  - air  - electricity  - gravity  - light   A:
**Answer**
light
Q: Q: What's the name for an atom that has gained or lost an electron?   Read this paragraph and choose the correct option from the provided answers:  Atoms cannot only gain extra electrons. They can also lose electrons. In either case, they become ions . Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons. If atoms lose electrons, they become positive ions, or cations. If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below ). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.   Choices:  - an photon  - isotope  - neutrino  - an ion   A:

Answer: A: an ion
