Gregor Mendel used only true-breeding plants. If he had used plants that were not true breeding, do you think he would have discovered dominant and recessive traits? why or why not?

How do I use the following terms to create a concept map?
meiosis, eggs, cell division, X chromosomes, sex cells, sperm, mitosis, Y chromosome
It has something to do with like putting a word in a bubble and then like drawing lines from it to another word but I'm not sure.

If each of the offsprings, TT, TT, Tt, and Tt, were allowed to self-fertilize, what are the next possible genotypes in the next generation?

For the question above this, what is the probability of each genotype?

Some scientists say that within 20-30 years they will have a way to make us live from 500 to 1000 years old.

Cells are the basic structure in living things.
All living organisms are made up of cell(s).
All cells come from other cells through cell division
Cells carry genetic material that gets passed on to other cells
Cells have essentially the same chemical composition.


SHORT PARAGRAPH

Cell theory can be said to be the foundation of biology. It tells us that animals and plants can be reduced to a single measurable unit of organization. It gives also gives us the definition of life. And now after laying static for its first 150 years in the 1950’s it gave birth science of DNA research. DNA research is providing an explanation of life itself and as well as cloning and stem cell research that may prove to cure diseases we now think are un-curable and extend our life expectancy dramatically

I have a test coming up soon for biology. I'm quite confused with some parts. Can some kind people help explain the following subjects:

A)The Genetic Equivalence of Differentiating Cells
B) DNA-RNA hydidization
C) Determination and Differentiation in cells (Possibly frog and snail)
D) Cytoplasmic Determination in cells
E) Cell-cell interactions

Explaining one of these topics will help me a lot!

Thanks.

I just watched a show on how this man had to relearn to hear electronically. A surgical implant was impended into his skull to interact with the region of the brain that is used to hear. As he was completely deaf. He relearned how to hear via electronic signals and can now hear better then an average person. As software updates so will his superior ability to hear. After this the show went into what could be as nano wires have already been designed to interface with the human brain without surgery but there are still issues with this, but have been tested on rats and have worked for five years.

So here is the question would you be willing to interface with anther person’s brain electronically? It should be possible in the next ten years.

Like cells muscles bones how it all works. Like a simple breakdown of everything in one book. Haha I know that is unreachable so maybe a few different ones. But I am thinking about maybe going into a medical profession and would like to understand the human body in alot more detail then I do now. So I will be prepared to start college. And I can have a little more confidence in being able to achieve my dream. I would also like to know how things like cancer are started I know the whole tumor aspect of it. But how exactly they are created is what I’m interested in. And basically about all the different cells and organisms that pass through and control our body.

i have a bio quiz tomorrow. we are going to have to look in a microcope and tell if the organims is a plant or animal cell and what stage of mitosis it is in. other than seeing a cell wall how can you tell the difference from plant and animal cells? are there any clues to help decide what stage of mitosis it is in. we also have to put a slide into focus.. any suggestions
