Answer - A
Semi-conservative model of replication involves the replication of DNA in all the familiar cells in such a way that each newly synthesized daughter cell contains a double helix with one new strand and one old strand.
Long term: I could either help a species have more genetic variation or wipe out an entire species. Short term: it could decrease food resources for other species.
the believe they move inside the membrane which is creating a gradient
The four characteristics of a mineral are:
1. Cleavage- the way it breaks, whether flat or roughly.
2. Luster- the way light reflects off of it, i.e. pearly, shiny, etc.
3. Streak- the color that its powder is
4. Hardness, for example, diamond is the hardest mineral, this is usually measured on the Mohs scale.
The first steps of catabolism generally take place in the cytosol.
Glycolysis and pentose phosphate pathway are metabolic process that occurs inside of the cytosol. Other catabolic processes such as the citric acid cycle, electron transport chain, and oxidative phosphorylation all take place in the mitochondrial membrane.
