sergejj [24]

To calculate this we will use the light equation:
$c=$ λ $*f$

We have Frequency $f=9.4* 10^{9}Hz$ .
We know that speed of light in vacuum is $c =3.8* 10^{8} m/s$ .
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).

So:
$f=9.4* 10^{9}1/s$
 $c =3.8* 10^{8} m/s$

 $c=$ λ $*f$
⇒ λ $= \frac{c}{f}$
⇒ λ $= \frac{3.8* 10^{8}}{9.4* 10^{9}}$
⇒ λ $=0.04 m$

In a dihybrid cross for round and yellow seeds (RrYy x RrYy), what is the probability of having green and wrinkled seeds?

Virty [35]

Answer:

The probability of having green and wrinkled seeds is equal to $6.25$ %

Explanation:

Here R allele is dominant over r allele and Y allele is dominant over y allele.

Thus, a green phenotype will have genotype rr

and a wrinkled phenotype will have genotype yy

The punnet square representing the cross between RrYy and RrYy is as follows -

RY Ry rY ry

RY RRYY RRYy RrYY RrYy

Ry RRYy RRyy RrYy Rryy

rY RrYY RrYy rrYY rrYy

ry RrYy Rryy rrYy rryy

Out of all 16 offspring, only one offspring with genotype "rryy" represents green and wrinkled seeds.

Thus, the probability of having green and wrinkled seeds is equal to

$\frac{1}{16} * 100\\= 6.25$ %

Answer:

that's not a good idea, most teachers search the web to check for plagiarism, and if they did they would see this question. but I'd say to go over the main facts, such as their diet, their ecosystem, and animals that prey on them. then add a few facts as space fillers if you need to.
