What do a phosphate group, a pentose sugar, and a nitrogenous base make up?
The organelle that is the site of aerobic cell respiration and is found in most eukaryotic cells.
What is a Mitochondrion?
The first part of the name in the binomial system for naming organisms.
What is a genus?
This is the principal external source of energy that sustains the vast majority of ecosystems.
What is sunlight?
The type of chemical reaction links monomers to form macromolecules by releasing a water molecule
What is a condensation reaction
The smallest units of self-sustaining life and existing cells can only come from preexisting cells.....
What is cell theory?
Physical and chemical barriers, such as the skin and mucous membranes, as a primary defence.
What is the innate immune system?
A group of interacting organisms of the same species living in a specific area.
What is a population?
The physical property of water that results from hydrogen bonding and allows small organisms to move across its surface?
What is Cohesion?
A solution that has a higher solute concentration than the cytoplasm of a cell, causing water to leave the cell?.
What is hypertonic?
The hormone secreted by the pineal gland to regulate the sleep-wake cycle as part of circadian rhythms.
What is melatonin?
Used to calculate allele and genotype frequencies in a population that is in genetic equilibrium.
What is the Hardy–Weinberg equation?
The enzyme responsible for unwinding the DNA double helix and breaking hydrogen bonds between strands during replication.
What is Helicase?
The phase of mitosis where sister chromatids separate and move toward opposite poles of the cell.
What is Anaphase?
The technique that uses the gradual accumulation of sequence differences to estimate when clades diverged?.
What is the molecular clock?
Food chains rarely extend beyond four or five trophic levels because of this process occurring between each level.
What is energy loss between trophic levels?
A DNA molecule wrapped around a core of eight histone proteins, held by an additional histone.
What is a nucleosome?
This theory explains the origin of eukaryotic cells via the internalisation of prokaryotes that evolved into mitochondria and chloroplasts.
What is endosymbiosis?
This genetic inheritance pattern occurs in the human ABO blood group system when both the IA and IB alleles are expressed equally in the phenotype.
What is codominant?
This type of speciation occurs when populations of the same species become geographically isolated and evolve into separate species.
What is allopatric speciation?
