Answer:
They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
Explanation:
<span>The answer is I, II and III. These
microbes can be funds even in hydrothermal vents at the bottom of ocean
trenches where they convert chemicals to organic matter. Most are critical in
the many nutrient cycles such as the nitrogen and carbon cycles. These microbes form the
base of the food chain since they support higher organisms such as paramecium
which are in turn eaten by higher organism such as amoeba. The amoebas are then
fed by tadpoles, for example, and the tadpoles are eaten by fish…and etcetera. </span>
Because you only get generic material from each parent, 23 from each adding up to 46
Answer:
Explanation:
Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
Answer:
In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. ... A theory on the other hand is a principle set to explain phenomena already supported by data.
