Think of the nucleus through this analogy: the brain of the human body contains all of the information inside of it that allows us to move and think, just like the nucleus contains all of the information for our beings inside of it. The skull is like the phospholipid bilayer (plasma membrane) surrounding and protecting the nucleus. Just as our brains are the control centers of our bodies, the nuclei are the control centers’ of cells.

To construct a mapping cross of linked genes, it is important that the genotypes of some of the gametes produced by the heterozy

FrozenT [24]

Answer:

False.

Explanation:

Linked genes are the genes that are present on the same chromosome and can undergo the process the recombination. The recombinant progeny are obtained by the crossing of the linked genes.

The recombinant frequency and map distance can be deduced by the mapping of the linked genes. The genotype of the heterozygote cannot be deduced by examining phenotype and sometimes the recombinant progeny is completely different from the parents as well as from the heterozygotes.

Thus, the correct answer is false.

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
