What else can I help you with?
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
Why an experiment must have control?
An experiment must have a control to show what would happen if no factors were changed.
What must happen before a hypothesis become a theory?
The Hypothesis Must Be Supported In Order For It To Become A Theory
A protein consisting of six amino acids undergoes hydrolysis How many water molecules must be broken down and reattached to amino acid molecules during this process?
Five. One molecule of water will be used to break each bond between the amino acids. Since there are five bonds, then five molecules of water will be required for the hydrolysis of this peptide.
What freezes faster saltwater or plainwater?
Plain water because the salt in the other water lowers the freezing point. All molecules must line up in order to freeze, therefore if adding salt, the Na and CL must line up with the water molecules in order to freeze. With plain water, the molecules line up faster and thus freeze faster.
What happen for heat to be transferred by thermal conduction?
Two molecules must collide with each other.
What must happen to the molecules to get into the blood?
Molecules must pass through cell membranes or be absorbed by cells lining the digestive tract to enter the blood. This process can be facilitated by active transport, passive diffusion, or specific carrier proteins, depending on the molecule. Once absorbed, molecules are transported through the bloodstream to reach their target tissues.
What must happen to glucose moleculs before respiration begins?
the glucose molecules must break down into two smaller molecules
What must occur for diffusion to happen?
two molecules must collied before diffusion happens.
What needs to happen for conduction to occur?
Two molecules must collide with each other.
What must happen with the water molecules so that they can dissolve compounds?
The water molecules surround the solute (stuff being dissolved) and separate the particles.
What 2 things must happen for a solute to dissolve in a solvent?
The bonds between ions or molecules of the solvate must be broken. The solvent must be in a sufficient amount and an adequate temperature.
What must happen to some of the molecules in the air for a spark to occur?
Some of the molecules in the air must be ionized, meaning they lose or gain electrons, to create charged particles that can conduct electricity. When these charged particles accumulate enough energy, a spark can occur due to the flow of current through the air.
What happens to the bonds of substances during chemical reactions?
Well, First the starting bonds must break molecules are always moving if the molecules bump into each other with enough energy, the chemical bonds in the molecules must break.
Can relatives give each other blood regardless of blood type?
No. You must match type.
Must sugar dissolve in blood to enter cells?
No, sugar enters cells through facilitative diffusion, a process that does not require it to dissolve in blood. Cells use specialized transport proteins to move sugar molecules from the blood into the cell.
What blood type do the parents have to be to make an A positive baby?
One of the parents must be A or AB, and one must be positive.
