Answer:
the answer is b (horizontal rock layers, each layer is younger than the one below it)
Explanation:
in rock layers, the top layer of a rock will be the newest, or youngest. and the very first layer at the bottom will be the oldest layer since the layers build on top of each other, hope that helps :)
Sedimentary rocks were originally in horizontal layers best describe law of superposition.
What is law of superposition?The law of superposition is a principle that guide stratigraphy stating which state that within a sequence of layers of sedimentary rock, the oldest layer is normally found at the base and that the layers continue to become younger with ascending order in the sequence.

-amino acid1-amino acid2-amino acid3-amino acid4-amino acid5-amino acid-6-amino acid7-
A) Which amino acid residue's backbone forms a hydrogen bond with the backbone of the seventh(7th) residue?
B) which of the following peptide segments is most likely to be part of a stable alpha helix at physiological pH?
A) -Lys-Lys-Ala-Arg-Ser-
B) -Gly-Arg-Lys-His-Gly-
C) -Pro-Leu-Thr-Pro-Trp-
D) -Gly-Gly-Gly-Ala-Gly-
E) -Glu-Glu-Glu-Glu-Glu-
F) -Glu-Leu-Ala-Lys-Phe-
G) -Tyr-Trp-Phe-Val-IIe-
Answer:
The correct answers are "amino acid3" and option F) "-Glu-Leu-Ala-Lys-Phe-"
Explanation:
The alpha helix is one the most common secondary structures of proteins, characterized by seven residue repeating units that alternate hydrophobic and hydrophilic residues. This sequence match with the peptide segment "-Glu-Leu-Ala-Lys-Phe-", where glutamic acid (Glu) is hydrophilic, leucine (Leu) is hydrophobic; and it does not contain amino acids that disrupt alpha helix such as proline and glycine. The alpha helix structure is stabilized by hydrogen bonds within the residue's backbone, one of them stablished between the third and the seventh amino acid residues.

A student made a model of a river in a sandbox. A pile of
sand represents soil and bits of rock in the riverbed. Water
pouring from a hose represents river water as it flows
downhill.
Which two characteristics are limitations of the student's
model?
A. The model is much smaller than a real river.
B. The model is missing plants, fish, and other details
found in a real river.
C. The model soil is nothing like the soil found in a real
riverbed.
D. The model river water flows downhill instead of
uphill like real river water does.
The two characteristics that are limitations of the student's model are:
A. The model is much smaller than a real river.
B. The model is missing plants, fish, and other details found in a real river.
The first limitation of the student's model is that it is much smaller than a real river. A sandbox model cannot accurately represent the scale and size of a natural river system. Real rivers can span for miles with varying widths and depths, while a sandbox model is limited in size and cannot capture the full complexity of a river's dimensions.
The second limitation is that the model is missing plants, fish, and other details found in a real river. A real river ecosystem consists of diverse flora and fauna, including vegetation along the riverbanks, aquatic plants, fish, insects, and other organisms. These elements play crucial roles in the functioning and dynamics of a natural river system. However, the student's model does not include these essential components, limiting its ability to represent the complexity and ecological interactions present in a real river.
The model soil is not like the soil found in a real riverbed. In natural riverbeds, the soil composition is influenced by geological processes, weathering, sedimentation, and organic matter deposition. The pile of sand used in the student's model may not accurately mimic the intricate mixture of soil and rock particles found in a real riverbed, thereby limiting the model's ability to replicate the diverse characteristics and interactions within the soil environment.
Although not explicitly mentioned in the question, it is worth noting that the model river water flows downhill instead of uphill like real river water does. This discrepancy can be considered a limitation if the student's intention was to replicate the natural flow of water in a river. However, if the focus was solely on demonstrating the concept of water movement, this limitation may be less significant.

what is the purpose of having distilled water as one of your test substances?
Distilled water does not have any cellular or mineral contamination. It is used in experiments for accurate results.
What is distilled water?It is a type of water that is completely purified of any kind of impurities. It does not have any minerals, salts, or organic materials.
Distilled water is the liquefied stream. When the water is boiling, it turns into a stream. This is collected and the steam is turned back to liquid. The steam doesn't carry an impurity of water with it and so distilled water formed from steam is also devoid of any impurities.
Distilled water is safe to drink but it will not taste anything like regular water. The water in our homes is supplied with minerals. These minerals are required for various processes in our body. Distilled water doesn't have any such minerals. Hence it's safe to drink but it's not beneficial.
Therefore, distilled water is used in experiments as there is no chance of contamination or reaction with this. This is used as a control against the test substances.

What is ABO Blood Groupings?A system which is used to group human blood into different types that is based on the presence or absence of certain markers on the surface of red blood cells. The four main blood types are A, B, O and AB. The ABO blood group system is used to match the blood types of the donor and the person receiving the transfusion.
People with O blood group can donate blood to anyone and are called universal donors. People with blood type AB can accept blood from all donors and are called universal recipients. People with type A or B can receive matching blood or type O blood.Blood group A has A antigens on red blood cells, with anti-B antibodies in the plasma.
Blood group B has B antigens with anti-A antibodies in the plasma
Blood group O has no antigens, but has both anti-A and anti-B antibodies in the plasma

Juan, a biologist, notices that a particular group of hummingbirds leaves during the colder winter months and returns during the warmer spring months. Juan hypothesizes that the birds fly south to locations with warmer weather and blooming flowers during the winter months. Which procedure should Juan use to test his hypothesis?
This question is incomplete because the options are missing; here is the missing section:
Which procedure should Juan use to test his hypothesis?
A. Survey northern and southern residents about the birds in their areas.
B. Observe the direction the birds fly when they depart in the winter.
C. Tag the hummingbirds with transmitters and track their movement.
D. Set up observation posts in the south to verify the time of year that birds arrive.
The answer to this question is C. Tag the hummingbirds with transmitters and track their movement.
Explanation:
To prove or disprove his hypothesis about birds Juan needs to test the direction hummingbirds fly to during the winter because only in this way he can know if the birds fly to the South as he thinks or they go to a different place. Moreover, this can better be tested through precise instruments such as trackers because these will register the movement of birds and clearly show if they are going to the South. Moreover, others such as the opinions of residents or the initial direction when birds migrate might be inaccurate.
