You've been tasked to study the movements of condensed chromosomes during cell division.
You have access to a magnifying glass, a standard light microscope, a scanning electron
microscope and a transmission electron microscope. Which piece of equipment would you choose
and why? Also why would you NOT choose the others? (max 50 words)
Answers
In order to see something as small as a chromosome, It is necessary to employ the use of a scanning electron microscope.
The question states that we wish to study the movements of condensed chromosomes during cellular division. This means that we will need a scope capable of not only looking inside of a cell but even inside of the nucleus of a cell, an extremely minute space.
Logically, a magnifying glass will not be able to accomplish this given that it only allows us to see macroscopic elements, many hundreds of times bigger than what we wish to observe. We run into similar limitations with standard light and transmission microscopes. Although these allow us to see things on a microscopic level, they fall short of the desired capability.
Though the transmission microscope can see even smaller elements than a standard light microscope, both are limited to the surface of cells. The SEM or scanning electron microscope, on the other hand, allows the user to see elements down to 0.1 nanometers in size. Given that chromosomes are between 10 and 30 nanometers in size, we can use this microscope for the desired study.

Which of the following is an extremely dense form of connective tissue?
Answers
Answer:
the breast tissue
Explanation:
Tendons and Ligaments are the extremely dense form of connective tissue.
What are dense connective tissues?Dense connective tissue is also known as dense fibrous tissue which is a form of connective tissue composed mostly of fibers. These fibers are made of type I collagen which are rows of fibroblasts, the fiber-forming cells that make up the fibers, filled in between the collagen strands.
Tendons and ligaments are strong, rope-like structures which is formed by dense connective tissue where tendons connect skeletal muscles to bones, while ligaments connect bones at joints.
Ligaments have more elastic fibers which are more extensible than tendons. This connective tissue is found in the lower layers of the skin known as Dermis, where it is structured in sheets.
Thus, Tendons and Ligaments are the extremely dense form of connective tissue.

is a chemical substance that is produced in substantial quantities, and is reasonably expected to be released in to the environment in substantial quantities a risk trigger, standard trigger, or an exposer trigger?
Means that the EPA has made a determination that a chemical or biological agent may present an unreasonable risk both in toxicity and exposure.
a. exposer trigger
b. standard trigger
c. risk trigger
Answers
Answer:
c-risk trigger
Explanation:
The Risk Evaluation process is the second step, following Prioritization and before Risk Management, in EPA’s existing chemical process under TSCA. The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation. As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific-evidence.
