The polysaccharide cellulose is composed of sugar monomers linked through ______ linkages, with their CH2OH groups in _________ direction relative to the neighboring monomer. Select one: a. Beta; opposite Correct! Polysaccharides of nondigestible Carbohydrates (the "fiber" in our diets) are held together by bonds known as beta linkages between individual monosaccharides; their CH2OH groups are orientated in an opposite direction relative to its neighbors. These bonds make cellulose indigestib...

Even though the amino acid sequence between subunits of hemoglobin and myoglobin are not exactly the same, there are other similarities between the two proteins. Which level of protein structure differs when comparing myoglobin to hemoglobin? 1. Primary 2. Secondary 3. Tertiary 4. Quaternary 43. As carbon monoxide binds to hemoglobin, the protein subunits...

Primary structure consists of the order of ______ in a protein. These are held together with ______ bonds that are formed by a ______ reaction. Select one: a. Amino acids, peptide, dehydration b. Nucleotides, peptide, dehydration c. Amino acids, peptide, hydrolysis Incorrect. A part of the response is correct. Amino acids are bonded together to make proteins. The bonds holding these amino acids are referred to as peptide bonds. However, the combination of the two amino acids results in loss o...

Some Diseases • HIV/AIDS o HIV- Human immunodefiencey virus  A person infected who is infected with HIV may be symptom-free for many years, even while the virus is actively attacking the immune system. It is present in the blood and some body fluids, it is most effectively transmitted (spreads from one person to another) ny actions or practices that involve the exchange of blood or body fluids between people. Transmitted in semen or vaginal fluid during unprotected anal, vaginal, ...

DNA is an incredible molecule that forms the basis of life on Earth. DNA molecules contain instructions for building every living organism on Earth, from the tiniest bacterium to a massive blue whale. DNA also has the ability to replicate, or make copies of itself. This allows living things to grow and reproduce. 1. Look at the DNA molecule shown at right. What does it look like? This shape is called a double helix 2. Based on this picture, how do you think a DNA molecule makes a copy of ...

Insertion - attachment of muscle's other tendon to movable bone, usually distal belly (body) - fleshy portion of muscle between their tendons (origin and insertion) Actions - main movements that occur when the muscle contracts reverse muscle action (RMA) - during specific movements the actions are reversed; • bones act as levers, and joints function as the fulcrums of these levers • lever: rigid structure that can move around a fixed point called a fulcrum • effort: c...

Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller? Make sure the cell grows to full size. The genetic information of a cell is carried in its DNA (short for deoxyribonucleic acid). What do cells need to do between divisions to make sure that a full set of DNA gets passed on to each daughter cell? The DNA must be copied so there is a full set of DNA for the daughter cell.
