Answer is B. Best way to check is make a square
Explanation:
It correctly reads;
A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:
1. Explain why the energy transfer is not the same between the three tests of the experiment.
2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.
Answer:
1. It secretes a peptide/protein hormone.
Explanation:
The above mentioned answer is more likely true for this question.
Because, rough endoplasmic reticulum is the cytoplasmic organelles which are involved in post-translational modification of peptide chains. After that, peptide chains are further modified (folded) in golgi apparatus. It's means that abundance of rough endoplasmic reticulum and golgi apparatus present in cells ensure the formation and secretion of peptide/protein hormones.
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
- Transcription
- Translation
During transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

Answer:
Pollution prevention
Explanation:
The water conservation strategy being used when a household uses eco-friendly cleaning products would be <u>pollution prevention</u>.
<em>The cleaning of household materials generally generates wastewaters that somehow find their way into the water cycle of the environment. </em><u><em>Eco-friendly products are those that do not harm the environment in any way </em></u><em>and the use of eco-friendly cleaning products would ensure that the wastewaters generated from cleanings are minimally polluted, effectively conserving the water due to the environment.</em>
