Answer:

because they are plastic shopping bags are increasingly recyclable or biodegradable .Traditional plastic bags are usually made from polyethylene, which consists of long chains of ethylene monomers. Ethylene is derived from natural gas and petroleum. The polyethylene used in most plastic shopping bags is either low-density (resin identification code or, more often, high-density (resin identification code.Color concentrates and other additives are often used to add tint to the plastic. Plastic shopping bags are commonly manufactured by blown film extrusion.

Answer:

In my opinion the word reason here is RENEWABILITY/SUSTAINABILITY.

Explanation: Renewability and Sustainability are both synonyms and can be defined as the ability for something to be produced or sustained for a long period of time without damaging the environment or without depleting a resource. Modern plastic shopping bags are increasingly recyclable or biodegradable. modern bags are made of vegetable-based bioplastics, which can decay organically and prevent a build-up of toxic plastic bags in landfills and the natural environment.

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.

What causes the colored bands in the spectra we see?
storchak [24]

Answer:

Each of the different colors has its own wavelength, which reflects and refracts at its own angle, different from all the other colors. When light passes through a prism (a triangular piece of glass), it is reflected and refracted into a continuous band of colors called a spectrum.
