Explain the relationship between genes, chromosomes, and proteins – Genes are sections of DNA that code for traits, the entire strip of genes is called a chromosome, and the code is used to create proteins.
Secondary growth – the growth in thickness of a plant
polypeptide – long chain of amino acids that make proteins
Phenotype – The observable expression of an organism's genes
What are data? – Data are recorded observations or items of information
The roles of the plasma protein fibrinogen – It forms mesh of blood clot when activated
alveoli – Small spherical chambers in the lungs where gas is exchanged.
Based on the phylogenetic tree above, which of the following two groups are most closely related?
Two species evolve in response to changes in each other over time.

A flower and a specific bird that pollinates it. – coevolution

Microtubule – Thin hollow cylinders made of protein that provides structural support for eukaryotic cells.
Vacuole – A fluid filled organelle that store enzymes of metabolic waste material
science – A body of evidenceā€based knowledge gained through observation and experimentation related to the natural world and technology. It is an organized way of using evidence to learn about the natural world. Word 'science' refers to the body of knowledge that scientists have built up over the years.
Bаsed оn the phylоgenetic tree аbоve, which of the following two groups аre most closely related?
Auxins – Plant hormones that cause the positive phototropism of plant shoots and seedlings.
Acquired Immunodeficiency Syndrome (AIDS) – The most advanced, and fatal, stage of an HIV infection.
reproductive isolation – Condition in which a reproductive barrier keeps two species from interbreeding
habitat isolation – When two species encounter each other only rarely.
organ – A collection of tissues that carry out a specialized function of the body.
