Answer:
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T). But there are two types of DNA in the cell – autosomal DNA and mitochondrial DNA. Autosomal DNA (also called nuclear DNA) is packaged into 22 paired chromosomes. In each pair of autosomes, one was inherited from the mother and one was inherited from the father.
Extra: Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner. Before replication can occur, the length of the DNA double helix about to be copied must be unwound.

There are 2 chromosomes.
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Human cells contain 23 pairs of chromosomes (46 chromosomes in total). Each chromosome is formed by 2 strands of DNA that hydrogen-bonded to each other make the classic DNA double helix (double-stranded DNA).

This sample of air at 35°C and 60% relative humidity holds ____ grams/cubic meter of water vapor. The same sample of air at 40°C can hold a maximum of 50 grams/cubic meter of water vapor. If the air currently holds 30 grams/cubic meter, then its relative humidity is ____%.
Answer:
Since a sample of air at 35 ° C and 60% relative humidity holds 26.25 grams / cubic meter of water vapor. The same sample of air at 40 ° C can hold a maximum of 50 grams / cubic meter of water vapor. If the air currently holds 30 grams / cubic meter, then its relative humidity is 60%.
Explanation:
To solve the following question, the following calculations must be performed:
If 40ºC can have a maximum of 50 grams per cubic meter of water vapor, this would imply a total of 100% humidity. Thus, if 35º had 100% humidity, the amount of grams per cubic meter of water vapor would arise from the following calculation:
40 = 50
35 = X
35 x 50/40 = X
1750/40 = X
43.75 = X
Now, if this implies 100% humidity, to determine 60% humidity the following calculation must be carried out:
100 = 43.75
60 = X
60 x 43.75 / 100 = X
2625/100 = X
26.25 = X
Therefore, if with 100% humidity you have 50 grams per cubic meter of water vapor, with 60% humidity you would have 30 grams of water vapor per cubic meter.

What is meant by the term "UV"? In your answer, please explain how it
impacts humans and what it has to do with the atmosphere.
Answer:
The term UV stands for Ultraviolet.
Explanation:
Ultraviolet light is a form of electromagnetic radiation which is shorter than that of visible light, but longer than X-rays. This impacts humans because it can provide harmful effects. For example, UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles and leathery skin. They also cause eye problems. However, our atmosphere blocks a lot of the UV rays from the sun which is amazing because if we were every exposed to it, we would die lol
"Ultraviolet light can't be seen by the human eye but is a part of sunlight. It can be harmful to us if we are exposed to it (sunburn!) but it is mostly absorbed by the atmosphere. The presence of UV light in sunlight can be shown by using fluorescing UV-sensitive beads."
Hope that helps!

The DNA sequence TTT codes for the amino acid lysine. The DNA sequence TTC
also codes for lysine. What can you conclude from this information?
Answer:
The genetic code is degenerate and therefore mutations may go unnoticed.
Explanation:
Each triplet of nucleotide bases, which is known as a codon, encodes for a specific amino acid during translation. However, a single amino acid may be coded by different codons. It is for that reason that the genetic code is considered to be degenerate. In this case, Lysine amino acid can be encoded by both TTT (UUU in the mRNA) and TTC (UUC) codons, thereby a mutation T>C at the third nucleotide codon position does not affect the resulting protein (i.e., it is a silent mutation).
what three phases of the cell cycle are considered interphase
Answer:
The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.
Explanation:
The three phases of the cell cycle that are considered interphase include G1, S phase and G2.
The cell cycle can be divided into the interphase and mitotic (M) phases.The interphase can in turn be divided into a Growth G1 phase, synthesis (S) phase and Growth G2 phase.The synthesis of the genetic material (DNA) occurs in the S phase, whereas in G1 and G2 the cell synthesizes all materials required to enter into cell division.In conclusion, the three phases of the cell cycle that are considered interphase include G1, S phase and G2.

Group of answer choices More negative E values mean: [ Choose ] More positive E values mean: [ Choose ] Compounds on the right side of the slash are: the reduced form of the compound Compounds on the left side of the slash are: the oxidized form of the compound Compounds at the top of the tower are more likely to: [ Choose ] Compounds on the bottom of the tower are more likely to:
Answer:
More negative E value means More likely to accept electrons.
More Positive E value means More likely to donate electrons.
Compounds on the right side of the slash are the reduced form of the compound.
Compounds on the left side of the slash are the oxidized form of the compound.
Explanation:
Redox tower is formed by reduction oxidation reaction which transfer of electrons happen between two species. It is a chemical reaction in which oxidation number of ions changes due to gain or loss of electron.
Redox reactions involves loss/gain of electrons.
A redox reaction equation is one in which a chemical specie either donates or accepts electrons. If the value of E is negative, the specie most likely donates electrons while a positive E shows that the specie readily accepts electrons.
The compound on the left side of the slash is oxidized while the one on the right side of the slash is reduced.

What ecological factors do you think might come into play when deciding how to time a pulse flow?
Answer:
- Species inhabiting the river and surrounding areas
- Hydraulic characteristics
- Geomorphology dynamic
- Water quality
Explanation:
Presence of different species: Assay the species inhabiting the area of the river corridor. These species include invertebrates, animals such as fishes, amphibians, reptiles, birds, and mammals, and plants living near the shore and on the floodplain. These species might be affected in some portion of their life cycles by the difference in the river pulse flows. Life stages and population dynamics might be considered of importance when timing the pulse flow.
Hydraulic characteristics: Habitat in aquatic systems varies according to the season and the pulse flow. Depth, velocity, substrate, and instream cover might be considered important factors influencing the presence of different species and their development.
Geomorphology: Refers to the shape of the channel and floodplain. These will depend on the stream velocity, sedimentation, depth, among others. The river geomorphology is in constant change, from season to season. This dynamic also affects the shape of the floodplain and riparian zone.
Water quality: Refers to the difference in sediments, suspended elements, available nutrients, dissolved oxygen, and temperature. All of these affect and influence different forms of life and their evolution through the corresponding cycle stages.
