The macromolecule that deals with long-term energy
Lipids
Which stages of the cell cycle happen within mitosis?
Prophase, Metaphase, Anaphase, Telophase
in a pedigree, what does a straight line between a male and female mean?
They are married
Within homeostasis, if the body is sweating, what does that mean the body is trying to keep in check
body temperature
The macromolecule that is not on food labels
Which stage does the nuclear envelope disapper?
Prophase
If you have a parent that is homozygous recessive aa and a parent that is homozygous dominant AA, what will the kids be
100% Aa
Three stages of cellular respiration
glycolysis, krebs cycle, and electron transport chain
A scientist discovers a new molecule that is composed of repeating units, contains carbon, hydrogen, and oxygen, and is primarily used for long-term energy storage. However, unlike typical examples, it is not soluble in water.
Which macromolecule is the scientist most likely studying?
Lipid
What three stages are in interphase
G1, S, G2
A parent is homozygous recessive and has blonde hair. The other parent is heterozygous and has brown hair.
What will the kids phenotype be?
50% brown hair and 50% blonde hair
Are ATP and NADPH a reactant, product, or neither within the photosynthesis process.
neither
Two athletes follow different diets: one consumes mostly carbohydrates, while the other consumes more proteins. During a long endurance event, the first athlete performs better initially, but the second maintains muscle function longer.
Which explanation best accounts for this difference?
A. Carbohydrates store genetic information used during exercise
B. Proteins provide quick energy faster than carbohydrates
C. Carbohydrates provide immediate energy, while proteins support structure and repair
D. Proteins are broken down into sugars more efficiently than carbohydrates
C. Carbohydrates provide immediate energy, while proteins support structure and repair
A researcher observes a group of cells and notices that the chromosomes are aligned along the center of the cell, but spindle fibers are not properly attached to all chromosomes. As a result, cell division is delayed.
Which phase of mitosis is being affected, and why is the delay occurring?
A. Prophase; chromosomes are condensing too slowly
B. Metaphase; the cell is ensuring all chromosomes are properly attached before separation
C. Anaphase; chromosomes are failing to move to opposite poles
D. Telophase; nuclear membranes are not reforming
B. Metaphase; the cell is ensuring all chromosomes are properly attached before separation
Where is called when went a trait is not expressed as much?
recessive
The four nitrogenous bases in RNA
Adenine, Uracil, Guanine, Cytosine
Enzymes lower what
activation energy
A drug prevents the formation of spindle fibers in dividing cells. Scientists test it as a cancer treatment because it stops rapidly dividing cells from completing mitosis.
Why would this drug be effective in slowing cancer growth?
A. It speeds up mitosis, causing cells to divide uncontrollably
B. It prevents chromosomes from being copied
C. It blocks chromosome movement, stopping cell division
D. It strengthens cell membranes to prevent mutation
C. It blocks chromosome movement, stopping cell division
What is the ratio for two heterozygous individuals?
3:1
Type of mutation that only changes one nucleotide
Point mutation
