A and D
Meiosis produces sperm cells and egg cells
And sexual reproduction uses sperm cells and egg cells to produce a fetus
Answer:
La célula es una estructura constituida por tres elementos básicos: membrana plasmática, citoplasma y material genético (ADN). Las células tienen la capacidad de realizar las tres funciones vitales: nutrición, relación y reproducción (ver t13). La forma de las células está determinada básicamente por su función.
Answer:
<u><em>Active Transport</em></u>
Explanation:
<u><em>active transport
</em></u>
During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Here we have to find the diameter of nucleus as the
diameter of atom is given.
Diameter of atom is 1 x 10⁻⁸ cm
Radius of atom = diameter/2
so, radius of atom = 1 x 10⁻⁸ cm/2
= 5 x 10⁻⁹ cm
To find diameter of nucleus, first we have to find the
radius of nucleus by using this formula,
R = rA⁽¹/³⁾ where <span>R = radius of nucleus, r = radius of atom and A is a nucleon
number, which is different for every atom
so, R=(5x10</span>⁻⁹)A⁽¹/³⁾
here atom is not mentioned, so we don't know the value of A
and Dimeter (D) = 2R, R = D/2
D/2 = (5x10⁻⁹)A⁽¹/³⁾
Diameter of nucleus (D) = 2((5x10⁻⁹)A⁽¹/³⁾)
