What complementary strand of DNA would be produced from the strand of DNA shown below?<br> TCG GA

Complementary pairing goes like this:

A pairs with T and 
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)

So if you have a strand that goes TCG GA then your pairing will look like this:

T A
C G
G C
G C
A T

Hope this helps!! :)

Genetic diversity is the total number of genetic characteristics in a species. Explain how chromosomal crossover contributes to
Arte-miy333 [17]

Answer:

Option (B).

Explanation:

Genetic diversity may be defined as the number of total genetic characteristics of a species. Genetic diversity helps the population to adapt in the changing environment. Crossing over provides a source of genetic diversity.

Crossing over is the process of exchange of genetic material during the process of meiosis. Thus, crossing over increases the variation of genetic characteristic in the haploid gamete cells.

Thus, the correct answer is option (b).

Sodium (Na) ____<br> atomic # 11<br> atomic mass: 23
SVETLANKA909090 [29]

Find # of electrons and draw them onto the Bohr model.

Assuming the atom has a neutral charge, the number of electrons equals the number of protons.  The number of protons is given by the atomic number, 11, so there are eleven electrons.

From the inner "ring" to the outer "ring":

1.  The first "ring", closest to the center of the atom, can take two electrons.

2.  The second "ring", level 2, can take the next six electrons.

3.  The rest of the electrons (three) can fit on the outermost ring.
