A newly discovered solar system is found 300 billion kilometers from the sun. How many AU does this represent? Show your work.

Biology

Aleksandr-060686 [28]3 years ago

1 kilometer = 6.68 × 10^{-9} (<<<AU is in scientific notation here)

To convert 300 billion kilometer (3,000,000,000 km)  into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × 10^{-9})

3,000,000,000 × (6.68 × 10^{-9}) =  20.04 AU

Hope this helped!

What are the three types of RNA and how does each contribute to protein synthesis?
Arisa [49]

There are 3 types of RNA:

mRNA (Messenger RNA): This RNA is in charge to travel the genetic information from the nucleous to the ribosome, where it binds to it and give the genetic instructions for protein synthesis.

tRNA (Transfer RNA): This RNA is in charge of providing the correct amino acid to the ribosome during protein translation.

rRNA (Ribosomal RNA): This RNA are structural proteins of the ribosomes.

In a population of lizards, the allele that causes red eyes (R) is dominant, while the allele that causes green eyes is recessiv
zhenek [66]
The answer is 0.47 or 47%.

Let's first distinguish some terms and their frequencies.
R - the dominant allele that causes red eyes
r - the recessive allele that causes green eyes

Since R is dominant over r, lizards with at least one dominant R allele will have red eyes. Therefore, the genotypes and the phenotypes are as following:
genotypes - phenotypes
RR              - the lizards with red eyes
Rr               - the lizards with red eyes
rr                - the lizards with green eyes

Now, we will use some Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1

where:
p - the frequency of dominant allele R
q - the frequency of recessive allele r
p² - the frequency of lizards with genotype RR
2pq - the frequency of lizards with genotype Rr
q² - the frequency of lizards with genotype <span>rr
</span>
We are interested in <span>the frequency p of the dominant R allele.
</span>So, we have the frequency (72%) of the lizards that have red eyes. However, lizards with genotypes RR and Rr will have red eyes. Since their frequencies are p² and 2pq, respectively, we have:
p² and 2pq = 72% = 72/100 = 0.72

Now, use this in the equation p² + 2pq + q² = 1:
0.72 + q² = 1
q² = 1 - 0.72 = 0.28

From here, we will calculate q and later p using the formula p + q = 1:
q² = 0.28
q = √0.28 = 0.53

p + q = 1
p + 0.53 = 1
p = 1 - 0.53
p = 0.47

Were the bacteria which infected Addie on the<br> playground alive? Explain your reasoning,
Serggg [28]

Answer:

Yes.

Explanation:

Bacteria are the simplest of creatures that are considered alive. Bacteria are everywhere. They are in the bread you eat, the soil that plants grow in, and even inside of you. They are very simple cells that fall under the heading prokaryotic. You don't usually get infected by dead bacteria, because  They get recycled. Unlike larger organisms, when single-celled organisms die, they usually undergo a process called lysis, in which the cell membrane disintegrates.
