Answer:The circulatory system consists of the heart and blood vessels which encompass all of the arteries, veins, and capillaries. The arteries carry oxygenated blood away from the heart, and veins return deoxygenated blood back to the heart. The main purpose of the circulatory system is to transport blood, oxygen, nutrients, and hormones to and from different cells and tissues throughout the body. This system works hand-in-hand with the respiratory system to facilitate the exchange of oxygen and carbon dioxide within the blood per the alveoli in the lungs. It is also very important for the removal of wastes and poisons within the body via the digestive and urinary systems.
Explanation:
As the students learned about a system that moved oxygen to the cells and contained structures that help the body fight infections, it means they were studying circulatory system. The correct option is C.
What is circulatory system?Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries transport blood away from the heart, while veins transport blood back to the heart.
The circulatory system transports oxygen, nutrients, and hormones to cells while also removing waste products such as carbon dioxide.
The circulatory system usually transports two varied fluids namely blood and lymph. Blood transports oxygen and nutrients to the cells of the body, as well as waste.
Blood also transports hormones, which regulate body processes, as well as antibodies, which fight invading germs.
Carrying immune cells to their destinations is one of the most important ways your circulatory system helps your immune system.
These vital cells could not function properly without your blood vessels and arteries.
Thus, the correct option is C.

1. Fill in the complementary DNA strand using DNA base pairing rules.
2. Fill in the correct mRNA bases by transcribing the bottom DNA code
3. translate the MRNA codons and find the correct amino acid using the codon table
4. Use the MRNA sequence to find the correct anticodon for the TRNA molecule
Answer:
PART 1: AAAGTTGCTGGTTG
PART 2:UUUCAACGACCAAC
PART 3:
UUU ---> Phe
CAA ---> Gln
CGA ---> Arg
ACC ---> Thr
AAC ---> Asn
PART 4: AAAGUUGCUGGUUG
Explanation:
Hello There!
PART 1: The first thing we want to do is find the complementary base pairs for the given DNA strand
Remember
The base pairs are
Adenine and Thymine
Cytosine and Guanine
The DNA strand given is
TTTCAACGACCAAC
Now we pair each nucleotide with its complementary base pair
T would change to A
A to T
C to G
and G to C
leaving us with
AAAGTTGCTGGTTG
PART 2: Now we want to transcribe the complementary DNA strand
IMPORTANT NOTE: Transcribing is pretty much like the first part, pairing each nucleotide with its complementary base pair except Adenine changes to Uracil not thymine
so adenine (A) changes to uracil (U)
thymine (T) to adenine (A)
guanine (G) to cytosine (C)
cytosine (C) to guanine (G)
AAAGTTGCTGGTTG
*transcribe*
and we're left with
UUUCAACGACCAAC
The next step is to pair the codons to its corresponding amino acid using the codon table provided below
The first thing we want to do is spread the codons out
Remember codons are a set of 3 nucleotides
Codon 1 (UUU) Codon 2 (CAA) Codon 3 (CGA) Codon 4 (ACC) Codon 5 (AAC)
Now we want to match each codon with its corresponding amino acid
Going from inside to outside using each letter we get that
UUU codes for Phe (Phenylalanine)
CAA codes for Gln (Glutamine)
CGA codes for Arg (Arginine)
ACC codes for Thr (Threonine)
AAC codes for Asn (Asparagine)
PART 4 Finally we want to find the anticodon of the mrna
Which is pretty much pairing each nucleotide base with its corresponding pair
Adenine to Uracil
Uracil to Adenine
Cytosine to Guanine
Guanine to Cytosine
So we'd go from UUUCAACGACCAAC to
AAAGUUGCUGGUUG

Answer:
Seismic Waves.
Explanation:
Geologists record the seismic waves and study how they travel through Earth. Different types of seismic waves behave differently. The speed of the waves and the paths they take reveal the structure of the planet. Using data from seismic waves geologists have learned that Earth's interior is made up of layers.

What health and environment factors negatively impact the flow of blood through the body?
Answer:
Certain types of Air pollution, Diseases
Explanation:
Environmental factors
Carbon monoxide is produced when fuels such as gas, oil, coal and wood do not burn fully. The increase of factories and manufacturing stations globally increases the chances of one inhaling carbon monoxide. When inhaled the carbon monoxide binds the haemoglobin in the blood increasing the chances of heart failure and brain damage.
Health factors
Health conditions such as Obesity, Diabetes can contribute to poor blood flow in the body. If someone were to suffer from obesity they would consequently have fatty deposits in the lining arteries. These deposits shrink the space that blood can pass through arteries. This means the heart has to pump blood harder to achieve the same task as someone able bodied. This dangerous because the heart would be at more risk of failing under the strain of the excess mass.

The idea of molecular clock genes has been studied for decades, but the hypothesis remains a controversial topic in evolutionary biology. Why do you think that is the case? What are three questions you still have about the use of molecular clocks?
Answer:
I think thats the case because a lot of scientists have evidence to back it up but some scietntists have other evidence for it not to be true and its just a back and forth problem.
1. Why does It assum that all changes in amino acid sequence are random and are not affected by natural selection?
2. Why do they use these clocks when our fossil record only goes back 550 million years ago?
3. What age range is appropriate for molecular clock dating analysis?
Explanation:
I don't know if this is right by this what I put. Have a good day!
The idea of a molecular clock gene remains a controversial topic because scientists have different opinions on genes mutations occurring at constant rates.
What are molecular clock genes?Molecular clock genes are genes which are assumed used as molecular clocks to determine the age of living organisms.
The idea of a molecular clock gene remains a controversial topic because different scientists have different opinions on if a changes in DNA over time can actually be used to determine the age of organisms,
Three questions that can be asked is this:
are mutations in DNA really random at all times?do mutations really occur at a constant rate?do the same mutations occur in the same species to the same extent?Therefore, until all scientists agree base on evidence, molecular clock genes remains a controversial topic.
