2) Anabolic metabolism is most similar to:
A) a car crashing into a wall at high speed
B) asexual reproduction in amoebas
C) a pump pushing water through a pipe
D) building a house out of bricks

3) If you drop a human cell into pure water in a petri dish, water molecules will pass into the cell membrane, causing the cell to swell or sometimes even burst if it has no active mechanism to expel the water. What process is happening here?

B) diffusion
C) osmosis
D) cellular respiration

4) When a non-diabetic person eats a candy bar, their pancreas produces blood glucose to balance out the sudden increase in insulin.
A) True
B) False

A) water towers are to firefighters.
B) tires are to a car
C) gas stations are to highways
D) propellers are to a helicopter

A) a freeze ray
B) a cloning tool
C) a hacking device
D) a spy satellite

7) why does sexual reproduction mix the DNA of two parents?
A) it's a unification of hapiloid cells
B) it involves a separation of chromatids to opposite ends of a cell.
C) spindle fibers pull the DNA into two parts
D) it's a process of cellular fission, not fusion

8) which symptom would most likely be a result of decay in connective tissue?
A) pain in your joints
B) poor memory
C) coughing and trouble breathing
D) unusual moles on the skin

B) Claude Bernard
C) Robert Hook
D) Schleiden and Schwann

A) True
B) False

11) Cellular respiration centers around .
A) cellular reproduction
B) the production of ATP
C) tissue creation
D) passive transport mechanisms

12) plant cells, unlike human cells, "cell walls" that contain the rest of the cell components. what are cell walls analogous to in the human body?
A) membranes
B) cytoplasm
C) blastiopores
D) mitochondria

Answer from: Quest

Mantle convection is the slow creepingmotion of earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.[1][2] the earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. this hot added material cools down by conduction and convection of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4] while in other regions, this material is impeded from sinking further, possibly due to a phase transition from spinel to silicate perovskiteand magnesiowustite, an endothermic reaction.[5]the subducted oceanic crust triggers volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6] and mantle plumes.[7]it is because the mantle can convect that the tectonic plates are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the hadean period, resulting in gravitational sorting of heavier molten iron, and nickel elements and sulphides in the core, and lighter silicate minerals in the mantle.
