Answer:
Ecologists
Explanation
often estimate the size and density of populations using quadrats and the mark-recapture method. A population can also be described in terms of the distribution, or dispersion, of the individuals that make it up. Individuals may be distributed in a uniform, random, or clumped pattern.
Answer:
A, B, C, E
Explanation:
A. not fully submerging the object when doing the fluid displacement procedure.
B. water that is left behind in the collection container when it is transferred for measurement.
C. water that soaks into the materials of the balls, affecting the mass in repeated trials.
E. water in the bucket, approximated to the closest 10 mL due to surface tension at the top of the bucket.
Answer:
The animal cell will take in water until it eventually swells or burst
Explanation:
Osmosis is an important phenomenon that drives the movement of water across membranes. It is defined as the movement of water molecules from a region of high water concentration/low solute concentration to a region of low water concentration/high solute concentration across a semi-permeable membrane.
In this case, the animal cell with a molar concentration of 2.0M is placed in 0.0M and 1.0M sucrose solutions. This means that the cell is placed in an hypotonic solution (solution with low solute concentration), hence, water will move from the extracellular solution into the animal cell since the solute concentration in the cell is more. The animal cell will begin to swell and eventually burst.
You can put wind energy propellers on the front of your car. This would be effective, as the high speed of the car would increase the rate of energy produced.
You could also have a metal rod slightly scraping the ground, and take the heat generated by friction to produce energy.
Hope this helps!
- An object's kinetic energy depends on its mass and its speed.
- The faster something is moving and the heavier it is, the more work it can do.
- Kinetic energy increases as an object moves faster.
- If an objects speed is doubled > kinetic energy is quadrupled.
<em>If an object is not moving, it does not have kinetic energy. </em>
