Felipe made a toy boat out of clay, but it kept sinking in water. He changed the boat's design by making it slightly wider than

before. Why did Felipe's newly designed boat float on water?
(a) He decreased the density by increasing the volume.

(b) He decreased the density by decreasing the volume.

(c) He increased the density by increasing the volume.

(d) He increased the density by increasing the volume.

The answer is A because the boat is being spread out which increases the total amount of space, or volume. The density is decreasing because the same amount of clay is being spread out over a wider surface. (Density is mass/volume and the mass is still the same but the volume has become smaller so that means that the density is also smaller)

Increased surface area so it was easier to float

(1) What transports oxygen through the body?
devlian [24]

Answer:

(1) Red Blood Cell

(2) Enzymes

Explanation:

(1) Oxygenated Red Blood cells transport oxygen from the lungs through the body using the arteries as a channel of movement to all organs.

(2) Enzymes are proteins that catalyze chemical reaction in the digestion of food so as to break food down into a form which can be absorbed by the body.

A mutation results in the production of much less DNA ligase than normal. What would be a likely consequence?
Ronch [10]
Answer: <span>DNA replication wouldstill  occur, but replication of the lagging strand would take much longer than normal.

</span><span><span>DNA ligase is the enzyme that binds the Okazaki fragments in the lagging strand. </span>Since the mutation resulted in much less DNA ligase, there would be less of this enzymes working for the replication process. Doesn't mean it can't happen, but it will be slower.

Facilitated diffusion requires
KiRa [710]

Answer:

<h3>A. </h3>

Explanation:

<h3>Tutorial</h3><h3>Diffusion</h3><h3>Diffusion means that the net movement </h3><h3>of particles (molecules) is from an area of high concentration to low concentration.</h3>

<h3>Graph of the simple and facilitated diffusion taking into account the rate of uptake and the concentration</h3>

<h3>If the particles can move through the lipid bilayer by simple diffusion, then there is</h3><h3> no limit to the number that can fit </h3><h3>through the membrane. The rate of diffusion increases linearly as we add </h3><h3>more particles to one side of the membrane.</h3>

<h3>If the particles can only pass through protein channels, then the rate of </h3><h3>diffusion is determined by the number of channels as well as the number of particles.</h3>

<h3>Once the channels operate at their maximal rate, a further increase in </h3><h3>particle numbers no longer increases the apparent rate of diffusion. At this limited rate we describe the protein channel as being saturated.</h3>

<h3>The cartoon illustrates several points about facilitated diffusion. The particles are more concentrated on one side of the membrane, and yet they can move in both directions. However, the net movement is from high particle concentration to low. If the number of particles gets so high on one side of the membrane that they</h3><h3> interfere with diffusion through the </h3><h3>protein channel, then we observe a limit to the rate of diffusion at the point of saturation.</h3>

<h3>Illustration of facilitated diffusion</h3><h3>animation used with permission of the Virtual Cell Web Page</h3><h3>Problem 7 | Answer | Problem 8</h3><h3>The Biology Project > Cell Biology > Cell Membranes > Problem Set</h3>

<h3>The Biology Project</h3><h3>Department of Biochemistry and Molecular Biophysics</h3><h3>University of Arizona</h3><h3>May 2002</h3><h3>Revised: August 2004</h3><h3>Contact the Development Team</h3>

<h3>Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a </h3><h3>concentration gradient; facilitated </h3><h3>diffusion moves materials with and against a concertion gradient. </h3>
