state two features of diffusion that do no apply to active transport

Answers

diffusion moves ions from high concentration to low using no metabolic energy and active transport uses metabolic energy in the form of atp to move ions from high concentration to low concentration

What does active transport require that diffusion does not? Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

What two features distinguish active transport from diffusion? An example of diffusion is oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air. Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP)

What are the 2 key features of active transport? There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of glucose in the intestines.

Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

How does cooling of magma affect crystal size?

A) Slow cooling creates small crystals

B) Fast cooling creates both large and small crystals.

C) Slow cooling creates large crystals

D) Fast cooling create large crystals

Answers

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:

I learned about this, Uhm...

C is the right answer bc igneous rocks cool and form crystals.

Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.

Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

Pairs of chromosomes contain (the same/different) types of genes.

Answers

Answer:

The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

In South Carolina, there is an area of shoreline called Grand Strand. Its central part is not protected by barrier islands. Explain what you could infer about the impact that water movement has on this area.

A. Water movement has caused strong waves to build the shoreline up through the process of deposition.

B. Water movement has caused longshore currents to erode the sediment from one end of this shoreline.

C. Water movement has caused this land to erode because there is no protection from strong waves.

D. Water movement has caused a build-up of various inlets to form a combination of tides and currents.

Answers

The impact that the movement of the water has in this area, is that the movement of the water has caused the erosion of this land because there is no protection against strong waves.

What causes marine erosion?

Marine erosion, also called maritime erosion, is defined as “the process of wear, transport and sedimentation of rocks and coastal soils by erosive agents”. Fundamentally, it can be caused by the action of three factors:

WavesCurrents and Tides.

With this information, we can conclude that the impact that the movement of water has in this area is that the movement of water has caused erosion of this land because there is no protection against strong waves.

If I’m correct, it’s c

Answer:

C. There is a 25% chance of short offspring.

Explanation:

In the simplified genotypes of a Punnett square cross, we deal with two genotypes. In this case, we are looking at a cross between Tt and Tt. T is dominant and t is recessive, meaning that someone with any genotype with T in it will be tall.

TT, Tt, and Tt will all produce tall offspring, while tt will produce short offspring.

This means there is a 75% chance of tall offspring, or 3:4.

50% or 2:4 are expected to have the Tt genotype.

Only 1 of the 4 will produce short offspring, which is 25%.
