A pair of scissors is a simple machine. why?

Daniel [21]

Answer:

A pair of scissors uses a combined mechanism known as a compound machine. Compound machines are comprised of two or more simple machines in an effort to more efficiently exert force, like the cutting of an object. The blades of the scissors are a pair of wedges in a cross shape which pivot around a fulcrum.

What is the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells at night w

lions [1.4K]

Answer:

C. +23.1 kJ/mol

Explanation:

the formula to use to calculate the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells is:

ΔGt = RTIn $\frac{C_{2} }{C_1}$ + ZFΔV

let's list the values of the data we are being given in the question to make it easier when solving it.

Z= 1

F= 96500C (faraday's constant)

ΔV= 160mV = 0.160V

R= 8.314( constant)

T= 15ºC ( converting our degree Celsius into kelvin, we will have 273.15k+ 15 = 288.15K)

∴ T= 288.15K

Putting it all together in the formula, we have:

ΔGt = 8.314 × 288.15 × 2.303 log $\frac{C_{2} }{C_1}$ + 1 × 96500 × 0.160

ΔGt = 5517.25 $[ -(log(H^{+}_{out} ) + log(H^{+}_{in} )_{in}$ +15440

ΔGt = 5517.25 $(pH_{out} - pH_{in}$ +15440

Given that the pH differential gradient across the membrane is 1.4pH units. It implies that;

ΔGt = 5517.25 × 1.4 + 15440

= 7724.15 +15440

= 23164.15 Joules/moles

= +23.1 KJ/mole

Answer:

Parasitism

Explanation:

This type of relationship involves one organism living with, on, or inside another organism and harming it. This relationship involves:

Host - the one being harmed in parasitism in this case the fish.

Parasite - the organism (the one doing the harm) that benefits in parasitsm in this case the leech.
