Why do single cell organisms divide?

1 answer:

7 0

Single-celled organisms which use asexual reproduction can do so very rapidly simply by dividing into two equal halves. This is called binary fission. In yeasts the cell does not divide equally in two halves; instead, there is a large mother cell and a smaller daughter cell. This is called budding.

What makes an atom able to form a compound? * O different number of neutron than protons O unfilled outer electron shells O same

GaryK [48]

Answer:

same number of protons as electrons

Explanation:

The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element. ... If you change the number of electrons in an atom, you will get an ion of the element.

Can someone help me and explain why they got what they got?

allsm [11]

Answer:

24.32 amu

Explanation:

From the question given above, the following data were obtained:

Isotope A (Mg–24):

Mass of A = 24 amu

Abundance (A%) = 79%

Isotope B (Mg–25):

Mass of B = 25 amu

Abundance (B%) = 10%

Isotope C (Mg–26):

Mass of C = 26 amu

Abundance (C%) = 11%

Average atomic mass of Mg =?

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

= [(24 × 79)/100] + [(25 × 10)/100] + [(26 × 11)/100]

= 18.96 + 2.5 + 2.86

= 24.32 amu

Thus, the average atomic mass of Mg is 24.32 amu
