up.

I am not asking about whether you think abortion is right or wrong.

I am simply asking if what I heard is true.

Also because the answers of this question will be on both sides, could you tell me sources that back up your claim?

Thank you for your assistance.

Red blood cells contain no DNA. During differentiation that right was given up in order to be able to carry oxygen and sustain hemoglobin. Then how is it possible to use someone's blood to identify them? Blood type is not enough to identify a person.

normally these are simple for me, but apparently missing 1 day of class is a big deal. here's the problem they give me

a1 = [1, 4, -2] a2 = [-2, -3, 7], b = [4, 1, h].
for what values of h is b in the lane spanned by a1 and a2

I'm not entirely clear on what a span even is. this pos book explains it with one paragraph(literally) so I'm assuming it's not as hard as I'm making it out to be. The problem also states that I shouldn't make a sketch, does that mean I shouldn't draw an array? I feel like this simple assignment just made a turn for the worst.

I've looked and looked and still could not find the graphic representation for this. I have this graphing assignment in which I need to find the list of the number of hurricanes each year. I more than likely could just look at a list of past hurricanes but only get a few of them each year. All I need is a list or graph that shows the amount of tropical cyclones/hurricanes each year since whenever it was started to become recorded.

Any help?
