At least a dozen times, lava cascaded down the walls of the Inner Gorge, forming massive lava dams that blocked the flow of the Colorado River. ... 1064 a series of eruptions built the park's namesake cinder cone.

Answer:

No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary. But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to. This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development.

Answer:

99%

Explanation:

at a salt solution concentration of 2%, plasmolysis first started to occur.  So the other 98% in the "solution" would have just been water. Since  water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.

Answer:

Answer: A less dense and rises

Explanation:

Convection is a type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases due to presence of less number of mmolecules per unit volume. As the hot liquid becomes less dense, it starts moving upwards.

Thus convection occurs because heated material becomes less dense and rises.

Explanation:

Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.

Assuming this is a true/false question, the answer would be false.

According to the law of conservation of energy, energy is neither created nor destroyed; it simply changes forms.

Unless you are saying that some energy would be lost as heat, This is true.

Answer:

ae you trying to find the meaning?

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. The only way to use energy is to transform energy from one form to another.

ex: the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.

Answer:

diffusion and osmosis

Explanation:

lipid_ soluble substance

through lipid baleyer

through protein channel

Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.

Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.

Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

I think the answer is B. Immigration must outpace emigration. Hope this helps!

Hardy-Weinberg equilibrium is the principle of the genetic variation being constant. Each allele must be equally beneficial for a population to be in equilibrium. Thus, option C is correct.

Hardy-Weinberg equilibrium states the invariant nature of genetic variation when there are no disturbing factors in a population. For an equilibrium condition, the population should have a large size. Each allele must be equally beneficial so that there is no genetic drift.

There should be no immigration or emigration of the organism in a particular population as it affects the generation and individuals. Also, there must be no spontaneous mutations for the variation to occur.

Therefore, each allele must be equally beneficial for equilibrium.
