Answer:

Sample Answer:

Broom: While using a broom to sweep the floor, a person’s hands move a short distance. But the broom head moves a longer distance. This motion cleans the floor faster by removing dirt from a large area.

Claw hammer: Pulling a nail from wood requires more force than a person’s hands can exert. A claw hammer increases the force and helps to safely pull out the nail.

Screw-top lid: When turning a screw-top lid, the threads put force on one another, and the lid closes tightly without much effort.

Predict what would happen to typical animal cells placed in 0.0M and 1.0M sucrose solutions, and explain your prediction. The an
Softa [21]

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.

There is about 1,000 times as much DNA in a human cell as in a bacterial cell, but only 5 times as many genes. What accounts for
chubhunter [2.5K]

Answer:

Phenotypic plasticity

Explanation:

Humans have evolved over thousands of years to adapt to various environmental changes. For example, when we are in an environment that requires certain level of adaptation our off spring often formalizes epigenetic traits that lows them to overcome small changes in the environment. Over time certain genes that are turned on may remain on and eventually the ones that are off remains off. This give rise to some genes that "don't work"  after millions of years of such evolution we end up with a complex genome with more DNA than "working genes".
