The amount of heat energy added to silver to heat it from 25°C to 100°C is :

8737.5 J

<u>Given data: </u>

mass of silver ( m ) = 500 g

T1 = 25°C

T2 = 100°C

s ( specific heat of silver ) = 0.233 J/g.c

<h3 /><h3>Determine the amount of heat required </h3>

Applying the formula below for heat ( Q )

Q = ms * ΔT

   = 500 * 0.233 * ( 100 - 25 )

   = 8737.5 J

Hence we can conclude that the The amount of heat energy added to silver to heat it from 25°C to 100°C is :  8737.5 J.

Fructose-2,6-bisphosphate is a regulator of both glycolysis and gluconeogenesis for the phosphofructokinase reaction of glycolys
azamat

Answer: Glycolysis is stimulated by a high concentration of fructose-2,6-bisphosphate, and the gluconeogenesis is stimulated by a low concentration of fructose-2,6-bisphosphate.

Explanation: Fructose-2, 6-bisphosphate (F2, 6P) is an allosteric activator of the key enzyme in the glycolysis cycle, phosphofructokinase (PFK). F2, 6P also acts as an inhibitor of fructose bisphosphate phosphatase (FBPase) in gluconeogenesis. The concentration of F2, 6P is governed by the balance between its synthesis and breakdown, catalysed by phosphofructokinase-2 (PFK-2) and fructose-bisphosphatase-2 (FBPase-2), respectively. These enzymes are found in a dimeric protein and are controlled by a phosphorylation/dephosphorylation mechanisms. Phosphorylation of the dimeric protein results in an increased concentration of FBPase-2, leading to a decreased concentration of F2, 6P, thus activating the gluconeogenesis cycle. The concentration of PFK-2 is increased when the dephosphorylation of the dimeric protein takes place, leading to the increased concentration of F2, 6P, thus stimulating glycolysis cycle.

2 examples of when scientists used space probe technology to find out more about comets.
Tanzania [10]
A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information. A space probe is launched from Earth with a set of scientific instruments and tools used to study the atmosphere and composition of space and other planets, moons, or celestial bodies. A probe may operate far out in space, or it may orbit or land on a planet or a moon. It may make a one-way journey, or it may bring samples and data back to Earth. Most probes transmit data from space by radio. There are different types of space probes because they collect different science information about very different environments. The probes must be able to withstand the various extreme environments to collect data. Humans have been sending space probes into space since the 1950s. The next generation of probes will study samples taken from comets, asteroids, and eventually Mars.
