kvv77 [185]

Answer:

B) Lysosome

Explanation:

Lysosomes are cell organelles that found in eukaryotic cells. Lysosomes consists of a double membrane as a covering and an interior made up hydrolytic enzymes. These enzymes, which also known as digestive enzymes, have specific various catalytic functions in the breaking down of proteins and other complex molecules. Some examples of these hydrolytic enzymes that is found bounded in lysosome include proteases,glycosidases, phosphatases.

Answer:

Ос. He used DNA testing to compare evidence to possible criminals.

Explanation:

Detective Scott worked to solve cases by the use of DNA testing which is an efficient way to solve a criminal case because DNA testing provides all information about the criminal. Due to this DNA testing, he solved many cases and the criminal caught with the help of this testing. If he can't use this DNA testing method then the case would not be solved.

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
