Answer:
Glue and sawdust.
Explanation:
Glue and sawdust are the substances that applied in wood to fill up cracks and grooves. You can use the glue and sawdust method to fill the gaps present in the wood. This method is a quick and easy solution that successfully fill up the gaps and grooves on the wood. The method of using this method is, first fill the gap with a small amount of wood glue, then rub sawdust into the gap which attached the saw dust with itself and the gaps are filled.
Answer:
NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer electrons in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+
These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid intramembranes.
Outer membrane covers the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.
The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope.
Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.
Thus the rate of reduction of DCPIP is faster.The color changes to colorless increases when reduced , from blue color.
Explanation:
The KT boundary marks a mass extinction event. the KT boundary is the time between the Cretaceous and Tertiary periods. An asteroid hit the earth at the end of the Cretaceous and that caused the end of the Cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth, a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there were many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth.
Answer:
The activation energy required for an exploding firework is less than the activation energy required for a burning candle.
Explanation:
I did this in class. The height of the activation is lower for the firework than the burning candle.
