Answer:

Both A. and B.

Explanation:

Mitosis is splitting of one cell to create two identical "daughter cells".

Process is completed in four steps: anaphase, metaphase, telophase and prophase

Mitosis three main functions are growth and repair of cells, and asexual reproduction for the single celled organisms.

Hello!

Your answer is A. The daughter cells are genetically identical to both each other and to the parent cell.

The parent cell makes two copies of its chromosomes and separates them, then divides by cytokinesis, creating two genetically identical daughter cells.

The mesentery attached to the inferior margin of the stomach is called the ________.

vovangra [49]

The answer is greater omentum. The omentum is a membranous twofold layer of greasy tissue that spreads and backings the digestion tracts and organs in the lower stomach zone. The omentum is comprised of the more prominent omentum which is a vital stockpiling for fat stores and the lesser omentum which associate the stomach and digestion tracts to the liver.

Mars had an orbital period of 1.88 years. In two or more complete sentences,explain how to calculate the average distance from m

Vanyuwa [196]

This is an interesting problem involving astronomy, in fact, simple physics.
Let r=distance of sun to mars, in metres

Mars had an orbital period of 1.88 years.
=>
tangential velocity, v, of the planet, in m/s is
$v=\frac{2\pi{r}}{T}$
 $=\frac{2\pi{r}}{1.88*365.25*86400}$ m/s, accounting for leap years
$=3.371*10^{-8}\pi{r}$ m/s

The centripetal force, Fc, generated is
$Fc=\frac{mv^2}{r}$
where m=mass of mars = 6.39*10^(24) kg
$=\frac{mv^2}{r}$
$=\frac{6.39*10^{24}v^2}{r}$
$=7.26168*10^9\pi^2r$

The gravitation pull from the sun, Fg, is given by
$Fg=\frac{GMm}{r^2}$
where G=grav. const., =6.67408*10^(-11) m^3 kg^(-1) s^(-2)
M=mass of sun=1.989*10^(30) kg
$=\frac{6.67408*10^{-11}1.989*10^{30}6.39*10^{24}}{r^2}$
$=\frac{8.4826*10^44}{r^2}$

Since the radial distance is in equilibrium, the average distance, r can be found by equation Fc=Fg and solving for r:
Fc=Fg
=>
$7.26168*10^9\pi^2r=\frac{8.4826*10^44}{r^2}$
Solving for the real root:
$r^3=\frac{8.48256*10^44}{7.26168*10^9*%pi^2}$
$=\frac{1.1681263*10^{35}}{\pi^2}$
=2.279*10^11 m
