If a trait is mitochondrially linked, what is the mode of inheritance?
Expected ratio of a monohybrid cross...according to Mendel's laws.
What metabolic processes do all organisms undergo which demonstrate common ancestry?
What part of meiosis results in the reduction of chromosome number?
What is photosynthesis controlled by?
Why does increasing carbon dioxide concentration increase rate of photosynthesis?
homologous chromosome line up in the middle of the cell during which phase of meiosis
A person that has the gene for a trait or disease but doesn't show it
At the end of meiosis, each gamete formed should only have 1 copy from each homologous chromosome pair
chromosomes line up randomly during metaphase therefore it is possible for any combination of chromosomes to be passed on from parent to offspring.
some versions of genes are dominant over others
when the heterozygous genotype results in a phenotype where the two alleles are blended together.
In animal cells, glycolysis occurs in theinner mitochondrial membrane.cytosol.outer mitochondrial membrane.nucleus.mitochondrial matrix.
A primary function of cholesterol in the plasma membranes of some animals is tofacilitate the removal of hydrogen atoms from saturated phospholipids.facilitate cell-cell interactions by binding to receptors on neighboring cells.make the membrane more rigid, allowing it to resist pressure from outside the cell.enable the membrane to stay fluid more easily when the temperature drops.
Yeast cells grown anaerobically can obtain energy by fermentation, which results in the production ofATP, CO2, and ethanol.ATP, NADH, and pyruvate.ATP, CO2, and lactate.ATP and lactate.ATP, CO2, and acetyl CoA.
The complete oxidation of glucose in aerobic respiration occurs through which of the following sequence of metabolic reactions?glucose → glycolysis → pyruvate oxidation → citric acid cycle → electron transport chainglucose → pyruvate oxidation → glycolysis → electron transport chain → citric acid cycleglucose → glycolysis → citric acid cycle → pyruvate oxidation → electron transport chainglucose → citric acid cycle → glycolysis → pyruvate oxidation → electron transport chainglucose → pyruvate oxidation → citric acid cycle → glycolysis → electron transport chain
Which of the following statements about NAD+ is true?NAD+ is the source of electrons used in oxidative phosphorylation.NAD+ is oxidized by the action of dehydrogenase enzymes.NAD+ has more chemical energy than NADH.NAD+ is reduced to NADH during glycolysis.
Glycolysis results in a net production of which of the following from each molecule of glucose?2 NADH, 2 pyruvate, and 2 ATP6 CO2, 2 NADH, 2 pyruvate, and 2 ATP6 CO2, 2 pyruvate, and 30 ATP2 NAD+, 2 pyruvate, and 2 ATP4 NADH, 2 pyruvate, and 4 ATP
