Who came up with the theory of continental drift? Was his theory originally accepted by
the scientific community?
Answer:
scientist Alfred Wegener and no it wasn't accepted .
Explanation:
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

what are three things that an ecological pyramid shows that food webs
and food chains do not show.
Answer:
An ecological pyramid shows energy flowing through different ecosystems, the amount of energy that is being passed down, and the amount of organisms.
Explanation:
The three things that are not displayed by food chain and food web but showed by ecological pyramid are;
Energy flowing through different ecosystems.
Amount of organisms.
Amount of energy that is being passed down.
An ecological pyramid can be regarded as graphical representation that display relationship between different organisms in an ecosystem.The trophic levels in this ecological pyramid contains amount of organisms as well as mass which is biomass and the amount of energy that can be found in each level.Therefore, it shows the energy flowing through different ecosystems.

Various factors influences the fluidity of the phospholipid bilayer of the cell membrane. If we were to chart the composition of cell
membranes in organisms as we move north from the equator to higher latitudes around the Arctic circle, we would expect to find
phospholipids with
A)
fewer hydrophilic heads.
B)
fewer interspersed cholesterol molecules.
both saturated and unsaturated fatty acid tails.
D
an increase in the length of the fatty acid tails.
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity

Yuki has a bowl of ice. She places the ice in a warm room and watches as it melts into liquid water. Yuki then places the liquid water over a Bunsen burner and heats it until it vaporizes. Explain what happens to the water molecules in Yuki's experiment; from the beginning to the end of the experiment.
Answer:
ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)
