You are at the store with your friend's family and they are looking to buy a new refrigerator for their home. There are two opti

ons available that they are interested in buying. On one of them there is a sticker that says “Energy STAR Certified''. Below the sticker it says that this refrigerator is guaranteed to be at least 10% more energy efficient than non-energy star brands. How might you use your understanding of science to walk your friends' family through why this Energy STAR fridge is a better purchase for the environment?

Answer:

It will take 83 days to recover the extra cost

Explanation:

To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days

The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.

The calculations are set below:

Savings in running cost per hour = $0.1

Total savings in a year = 365 days ×  $0.1 × 24 = $876

Extra cost of Energy Star refrigerator = $200

If total savings for a year is  $876 , then equivalent length of time to save $200 would be

Length of time = 200/876 × 365 days = 83 days

It will take 83 days to recover the extra cost

The way that neurons communicate is through _____________ _________________ which release _________________ .
Ne4ueva [31]

The way that neurons communicate is through synaptic vesicles which release neurotransmitters.

<h3>What are Neurons?</h3>

The neurons are the basic structural and functional unit of the nervous system.

These neurons are able to communicate to each other through the neurotransmitters that are released by synaptic vesicles.

The neurotransmitters are chemical messengers that carry chemical signals from one neuron to another upon the generation of an action potential.

The synaptic vesicles are the organelles that house these neurotransmitters.

Ksenya-84 [330]

If a plant cell had a mutation such that the cyclic electron flow is observed at a much higher rate, which photosystem is most likely mutated such that energy is absorbed at a lower rate?

PSI

PSII

Answer:

PSII

Explanation:

Non-cyclic phosphorylation involves both PSI and PSII. The process starts with the splitting of water and excitation of electrons of the reaction center of PSII upon the absorption of solar energy at the wavelength of 680 nm. Any mutation in PSII would not allow the non-cyclic phosphorylation to occur when only cyclic phosphorylation would occur. The process of cyclic phosphorylation includes only PS I. Its reaction center absorbs maximum light at 700 nm and is cycled back while supporting ATP synthesis. Therefore, if a plant performs cyclic phosphorylation at a higher rate and absorbs less energy, this means that mutation was in PSII.
