The earth got hit by a meteor billions of years ago and now it sits on an axis
Answer:
Differences: Size
Similarities: Organelles
Explanation:
The most important difference is size. The volume of a typical human cell is 4,000 times more than the volume of a typical bacterial cell. Today's bacterial cells are direct descendants of the prokaryotic cells found in rocks that were formed one billion years after Earth.
Organelles are the biggest difference between bacteria and cells that make up the human body. An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane
The source of evidence refers to C. where the information came from.
There are two sources of evidence the primary or original source or evidence and secondary source. The primary source, in history, is anything that serves as an original source of information about the topic. It could be an artifact, document, manuscript, diary, autobiography and the like. Moreover, in the field of journalism, a primary source can be a person that has a personal or direct knowledge of a subject or situation or a written document by such a person. Meanwhile, secondary sources are evidences or sources that are extracted or build upon primary sources.
Second messenger systems: The amino acid-derived hormones epinephrine and norepinephrine bind to beta-adrenergic receptors on the plasma membrane of cells. Hormone binding to receptor activates a G protein, which in turn activates adenylyl cyclase, converting ATP to cAMP.
Mendel formed a hypothesis for the outcomes he observed in pea plants.
