The correct answer is:
<h2>
Glucose + fructose → sucrose </h2><h3>Explanation;</h3>
Glucose and fructose are monosaccharides and are the building blocks of sucrose, a disaccharide. Thus, disaccharides are just a pair of associated sugar molecules. disaccharide. They are remunerated when two monosaccharides are joined together and a molecule of water is eliminated -- a dehydration reaction.
2.The correct answer is:
<h3>d.The nucleic acid is DNA and would be found in the cell's nucleus.</h3><h3>Explanation:</h3>
The scientist can say with confidence that this DNA molecule is enclosed by a nucleus based on the combination of the nucleic acid defined. Only eukaryotic cells have a ladder structure. The prokaryotic cells have circular DNA and do not have any organelles, like the nucleus. Consequently, from the steps structure of the DNA, the scientist can see that the cell has a nucleus.
3.The correct answer is:
a.Enzyme activity will decrease, and the reaction will proceed very slowly, or possibly not at all.
Explanation:
The enzyme work under a standard conditions.they work under an optimized conditions if any of them is increased or decreased enzyme activity will b effected.
4.The correct answer is:
a.Adding an enzyme to decrease the activation energy of the reaction
<h3>Explanation:</h3>
Enzymes are macromolecular biological catalysts. Enzymes excite chemical reactions. The particles upon which enzymes may act are called substrates and the enzyme transforms the substrates into separate molecules known as outcomes.
5.The correct answer is:
a.As technology improves so will our understanding of cells.
Explanation:
The advancement in technology improves the understanding of cell and enables the scientist to learn about cell in more detail.
6.The correct answer is:
c.builds on the work of earlier scientists
<h3>Explanation:</h3>
As new work comes to light, a theory is changed; however, it cannot be terminated because one concrete research providing testimony toward it can disprove it.
7.The correct answer is:
b.The lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell.
Explanation:
It consists of a lipid bilayer with embedded proteins. The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
8.The correct option is:
d.fewer mitochondria since there will be fewer molecules left in the cell.
Explanation:
To actively transport molecules against its concentration gradient wanted energy which is generated by the ATP hydrolysis. As mitochondria make and store ATP, here more mitochondria are required to meet the increased energy requirement.
9.The correct answer is:
A protein acts as a pump and moves calcium ions from an area of low concentration to an area of high concentration.
Explanation:
Active transport is the transportation of molecules beyond a membrane from a region of their lower concentration to a region of their greater concentration—in the regulation against the density gradient.
10.The correct answer is:
d.Mitochondrium
Explanation:
The mitochondrion is a double-membrane-bound organelle found in most eukaryotic bodies. Some cells in some multicellular organisms may, though, lack them and present in plants and animal cell.
