<span>3.Equal numbers of eggs and sperm are produced by meiosis. </span>
<span>4.The gametes produced by meiosis ensure the continuation of any particular species by asexual reproduction.
</span>
The correct answer is <span>2. Meiosis provides for chromosomal variation in the gametes produced by an organism. It happened during cross-over and segregation and law of independent assortment.</span>
Sporozoites that have undergone radiation. The PfSPZ vaccine has been in development by the company. The premise of the vaccine is use to use these radiated sporozoites inside the body to bring forth an attack on the sporozoite, which will help the body prevent itself against further attacks of malaria. Due to its promising nature, the U.S FDA department granted it the fast track designation in 2016.
Pretty sure most of us know that already,so what's your question?You lost buddy?
Answer:
C. The properties of the mixture may be different from those of the original substances
Explanation:
You can work out the concentration of H+ ions (denoted as [H+]) easily on a calculator if you know the pH, which you do. The easiest way to work out [H+] is to do
. In your case, the maths here would be
, which gets you an answer of 1.58x
, or 0.000158. For 6.2 it would be
, which gives you 6.31x
, or 0.00000063. As you can see, the concentration of H+ ions is greater in pH 3.8.
To put it simply, the [H+] decreases the higher up the pH scale you go, and increases as you go lower, but now you know the maths to work it out for yourself too.
