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.

The answer is applying sustainable development.
The trend of declining ecosystem resource availability and increasing demand for these resources can best be countered by applying sustainable development. Sustainable development refers to the development in which the needs in the present is meet without compromising the future generation's ability to meet their own needs.
Answer:
C. They can grow to larger populations more quickly
Explanation:
Bacteria are the <u>key entities</u> of <u>biogeochemical cycle</u>s (Nitrogen, Carbon, Oxygen, etc.) on Earth. The strength of these cycles is typically achieved when they can multiply faster in a relatively <u>short time period</u>. If all bacteria on Earth start reproducing via sexual means only, then many of the biogeochemical cycles would take forever, thus <u>generating nutrients at a slower rate</u>. Since higher organisms (e.g. eukaryotes) depend on the abundant supply of nutrients, the overall life on Earth would be compromised to a larger extent in the absence of sufficient nutrients supply. Thus, it is <u>beneficial for all forms of life that bacteria reproduce mainly via asexual means</u>.
PS: A simple bacterium can produce millions of copies in 24 hours period.
Answer: Phosphorylation of mitotic sites at the start of mitosis (N-terminal S22 and C-terminal S392 in human lamin A/C)
Explanation: During mitosis the nuclear lamina is dissociated by phosphorylation- dependent mechanisms that causes conformational changes in structure at N- and C-terminals (non alpha helical terminals) during the start of cellular mitosis that leads to its disassembly. This is because the nuclear lamina has two sites that accept phosphates (phosphoacceptor sites) causing a phosphorylation reaction.
The nuclear lamina is a fibrillar network of intermediate filaments as well as membrane proteins and are involved in DNA replication, cellular division as well as providing mechanical support within the cell.
