Why do companies like nestle object to bottle deposit programs? what do they support instead?
Ahat [919]

Answer:

The companies take away the bottle as "security deposit and however they can recycle and reuse it."

Explanation:

When buying different beverages from a person distributing, a deposit needs typically to be paid to the distributor from the containers that have been taken. However, the distributor will issue a refund once the bottle that was taken has been returned to the place of purchase. Therefore, the distributor will reimburse the redemption of the retailer the amount that was deposited for every container. The additional handling fees usually added in some countries. The deposits that remain unredeemed are taken to the state or kept by distributors.

6. Delete any base (between the READING FRAME, excluding the start and stop codons) and show the change in the amino acid sequen
kati45 [8]
This is the DNA. I'm going to only use the upper strand to demonstrate what this strand would code for before and after a single bp deletion (so write it as mRNA). I will also write it how it's easier to see this which is to split them up into the 3 base codon system. Note that you don't need to know the amino acid code - you use a table to find these.

ORIGINAL (mRNA on top, Amino Acid (AA) on bottom:

5'-AGC GGG AUG AGC GCA UGU GGC GCA UAA CUG-3'
    SER  GLY  MET SER ALA  CYS GLY ALA  STOP LEU 

Note that the protein would stop being made at the stop codon and the LEU wouldn't matter at the end...

Now, I will remove one bp...(I bolded it up top). Rewrite the mRNA and find the corresponding AA...

NEW
5'-AGC GGG AUG GCG CAU GTG GCG CAU AAC UG-3'
   SER  GLY  MET  ALA  HIS   VAL  ALA   HIS  ASN .....

Completely different amino acid sequence after the methionine (MET). The stop codon is gone...the protein would continue being translated until it reaches another stop codon...so not what was supposed to be made!

The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square
DIA [1.3K]
Hey there!

Here is your answer:

Since there are not options im going to go with what i know:

<u>(Alleles)</u>

<span><u>heterozygous: A,a</u>
</span><u>homozygous: a,a</u>

<u>Therefore the Punnett square should look like this:</u>

<u>A, a</u>
<u>a IA,a I a,a</u>
<u>a IA, a I a, a</u>

Therefore the answer is 50% A,a , and 50% a, a!

If you need anymore help feel free to ask me!

Hope this helps!

When we look at a leaf, we see the colors of light that are reflected off its surface. How does this explain the relatively low
anastassius [24]
Oxygen is produced in the light stage of photosynthesis at Photosystem 2 and results from the splitting of water. Chlorophyll does not absorb green light so in green light there will be less water split and so less oxygen is produced.so thats how we know the reason why a leaf is the color that it is. basically it is because of chlorophyll.

Hope this helps.

Anuta_ua [19.1K]

Answer:

<em>The process of </em><u><em>exocytosis </em></u><em>could be responsible for its secretion. </em>

Explanation:

Exocytosis can be described as a process in which molecules are transported out of a cell in vesicles. The process of exocytosis usually requires energy as molecules are moved out of a cell by the method of active transport.

As certain cells that line the stomach secrete a protein and release it into the stomach we can infer that the process is exocytosis. Peptides, hormones and various antibodies are also transported to different locations through the process of exocytosis.
