What is complementary base pairing? Explain why complementary base pairing is necessary to maintain the double helix shape of the DNA molecule.
Answer:
A complimentary base pairing is how adenine can only bond with thymine and how guanine and cytosine through hydrogen bonding. It is necessary to maintain the double helix shape. Because it is opposite, that is why the DNA is that shape. It is anti parallel due to the Complementary base pairing.
Adenine can only bond with thymine and guanine with cytosine via hydrogen bonding. It's important to keep the double helix shape. Complementary base pairing causes antiparallelism.
Why complementary base pairing is necessary?Base pairs linked to a sugar-phosphate backbone form the double helix structure of DNA.
DNA is composed of four nitrogenous bases: thymine, adenine, guanine, and cytosine. Guanine and cytosine are linked by three hydrogen bonds, while adenine and thymine are linked by just two. The term for this is complimentary base pairing.
Complementary base pairing is critical for the formation of the helical helix of DNA because it permits the base pairs to be organized in the most energetically favorable manner. It is also essential for replication since it permits semiconservative replication.

How are the blunt and sharp pipettes
used in the cloning process?
(please answer in simple words i don't even understand the question)
Answer:
During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.

Earth is shown as a circle with a smaller circle labeled Moon above it. Points A and C are marked at the top and bottom ends of the circle representing Earth. Points B and D are marked at the left and right sides of the circle representing Earth.
In this current position, which coastline(s) are experiencing a daily low tide? (5 points)

4)

Answer:
Both B and D i believe
Explanation:
Both B and D experience the daily low tide.
What is Low tide?
One of nature's most dependable phenomena is the tide. We are convinced that the ocean waters will routinely rise and fall along our coastlines as the sun rises in the east and the stars appear at night.
The enormous forces that generate the world's tides are discussed in the pages that follow, along with the reasons why it is crucial for us to comprehend how they function.
When the moon and sun exert their energies on the oceans, very long-period waves called tides travel through the water. The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.
Therefore, Both B and D experience the daily low tide.

The diagram below shows the Moon's orbit around Earth. Letters A, B, C, and D represent four positions in the Moon's orbit.
What is the approximate length of time it takes the Moon to travel from position A to position C?
1 day
14 days
28 days
31 days
Answer:
14 days is the correct answer. Since it takes 27(approx) days to complete one revolution of the earth and will take (27/2=14) days to complete half of the revolution I.e. A to C.
The orbit of the Moon around Earth is shown in the diagram below. Four locations in the Moon's orbit are represented by the letters A, B, C, and D.
How long does it typically take the Moon to move from position A to position C?
The Moon takes 28 days to go from location A to position C, which is a rough estimate. The Moon is at perigee, or its closest point to Earth, at position A. The Moon is at its apogee, or furthest point from Earth, at location C. Even though the Moon's orbital speed varies, it does take about 28 days to go from perigee to apogee. The Earth's orbit around the Sun and the Moon's orbit are both inclined.
This indicates a tilt between the orbital planes of the Earth and the Moon. The Moon's location with relation to the Sun consequently shifts throughout time. The Moon appears to "wax" and "wane" in the night sky because of this. The 28-day synodic period of the Moon accounts for the Moon's shifting positions with respect to the Sun.
Therefore, it may be concluded that it takes the Moon 28 days to roughly travel from place A to position C. This is due to the Moon's relatively slow orbital motion, which takes around 28 days to complete from perigee to apogee and from one place in relation to the Sun to another.

____ The DNA “rezips,” reforming the original complementary cross-strand
bonds
____ The DNA and messenger RNA strands separate from one another and the
RNA leaves the nucleus
____ Helicase “unzips” the DNA-RNA hybrid
____ RNA polymerase joins the new RNA nucleotides into a single strand
____ Helicase “unzips” the DNA, opening the two strands of the double helix
____ Free RNA nucleotides make complementary pairs between their own
nitrogenous bases and the attached bases of the single DNA template
strand.
Answer:
6, 5, 4, 2, 1, 3
Explanation:
Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.
Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.
The process of transcription takes place in the following sequence:
1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.
2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.
3. The RNA nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.
4. DNA helicase unzips the DNA and RNA hybrid.
5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.
6. The two-strand of DNA is again joined via complementary base-pairing rule.

Environmental agencies throughout the world believe that humans have forced Earth out of its natural cycle. Consider the choices below as possible sources of empirical evidence for anthropogenic climate change. Which choice does not support this view?
Answer:
Human activities increases the concentration of oxygen in the atmosphere.
Explanation:
Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.

People with hemophilia need to have clotting factor proteins injected into their cells throughout their lifetime. Based on what you observed when you added proteins to change Greg’s stripe color, why do you think people with hemophilia constantly need to receive injections of the protein? *
Answer: people with hemophilia constantly need to receive injections of the protein because, hemophilia can causes internal bleeding in severe cases, which can result in the damage of organs and joint. This is because people who have hemophilia lack a specific protein (which is called a clotting factor) that enables blood to clot.
Explanation:
Hemophilia is a hereditary bleeding disorder which is characterized by either decreased, defective or absent production of blood clotting proteins.
The treatments needed will depend on the type of hemophilia and the severity of hemophilia. For example, if you have mild hemophilia (that is relevant clotting factor activity is greater than 5%, but less than normal), you may need treatment only when you are in preparation for a surgery or when you have an injury. However, if you have severe hemophilia that bleed frequently, you may need regular (several times in a month) to help prevent bleeding and help protect your joints from deformity and disability.
