Pick one biotic factor, if you were to change it dramatically somehow, how will this change affect the ecosystem?

If all plants were to die, photosynthesis wouldn't occur and that would affect the ecosystem because every other biotic organism would not have oxygen to breathe.

Below are statements that describe either traits that follow the typical pattern of Mendelian inheritance or sex-linked inherita

photoshop1234 [79]

Answer : Mendelian traits

1) A trait like eye color or height

2) Involves a dominant and recessive allele.

3) Predisposition to some diseases like diabetes and heart diseases.

4) These are equally likely to occur in males and females.

Sex linked trait

1) A trait like color blindness which affects many more men than women.

2) These are not equally likely to occur in male and female.

Explanation:

The Mendelian inheritance is based on the laws proposed by Mendel.The traits that follow these laws are called as Mendelian traits.

In an inheritance pattern, a Mendelian trait is the one which is controlled by only a single locus.

It is inherited in the manner that obeys Mendels laws -

1) Law of segregation - This law states that whenever gamete formation takes place each gene for a particular trait segregate from each other in such a way that each gamete carries only one allele.

2) Law of independent assortment- This law states that the genes for different traits segregate independent from each other during gamete formation.

3) Law of dominance- This law states that for every trait there are two alleles, one is dominant while the other is recessive.

Sex linked inheritance

It is the type of inheritance pattern followed by genes which are preesent on the sex chromosomes. Their inheritance varies from that of Mendelian pattern. If it is X linked dominant then each child of an affected mother has 50% chance of being affected whereas if it is recessive then a female can be a carrier or affected but a male will always be affected if it carries the allele.

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
