How can you tell the cell in question 8 is undergoing meiosis, not mitosis?
UkoKoshka [18]
This cell must be undergoing meiosis because homologous chromosomes are associated with each other at the metaphase plate which this does not occur in mitosis.

Answer:

The correct answer is D. Umbilical cord

Explanation:

The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

How easy or difficult was it to find an example of each category?
Anvisha [2.4K]
Depending on what resources you use, it can be easy or difficult to get examples of each categories

Some easy way can include searching google, wikipedia, encyclopedia.org, etc. These usually give you a broad and large amount of information that you can draw out of, and an over view that allows you to know what the paragraph would be talking about before you use it. 

Difficult ways would be searching through specific websites, such as national geographics, etc, which gives you specific details on the idea (and is more trusted then the others)

Remember too always get facts, not opinions, unless your question asks for others opinions, and to look for what researchers or well-known people within that topic says, and to not get any information from "who-knows-who-typed-it" websites, such as ask.com, etc.


hope this helps
