What is the major thing happening to a cell during G1?

Combine into one sentence. The earth and moon that were hit by asteroids throughout history, the craters on them were erased by weather, water and plants.

Asteroids are celestial bodies in the form of rock-like fragments with irregular shapes that move around the sun.

When the asteroid heads towards the earth, it will be eroded by the ozone layer, but if the size is very large, the asteroid will fall and hit the earth's surface. Some craters may form as a result of asteroids falling to earth, but they can be wiped from the earth's surface by weather, water and plants. So that the crater is almost invisible because it is similar to the rest of the earth's surface.

Sections of copied dna created on the lagging strand. True. These short DNA segments are called Okazaki fragments.

DNA replication is the process of doubling the DNA chain assisted by DNA polymerase before mitosis. DNA polymerase forms new DNA strands with the help of primase enzymes.

The lagging strand is the synthesized DNA strand and is located in the 5'→3' direction at the replication fork. The synthesized DNA strand is called an okazaki fragment, in which primase forms the RNA primer. During the replication process, the nucleotides will be added to the end of the sugar from the Okazaki fragment with the help of the DNA ligase enzyme so as to form a complete unit.

Prions describe a few lethal and contagious neuro degenerative illnesses in people and numerous other animals. It isn't understood what makes an ordinary protein misfold, however the subsequent unusual three-layered structure presents irresistible properties by falling close by protein particles into a similar shape.

The word prion is gotten from the expression "proteinaceous irresistible particle".

Answer: Negative geotropism

Explanation: The reason why bananas are curved is due to a process called negative geotropism. So, initially bananas start by growing towards the ground, but will eventually start growing towards the sun. With that being said, you’ll often find that some bananas are completely straight. This is because of an innovation known as bagging, whereby the fruit is covered in order to protect it from insects and animals.

Option 2 is Correct. In primary active transport, carrier proteins are used, but in secondary active transport, channel proteins are used.

In contrast to secondary active transport, which can move two substances at once, primary active transport can only move one chemical at a time. The two molecules moving in secondary active transport may do so in different directions or in the same direction (both into the cell) (i.e., one into and one out of the cell).

Membrane transport proteins can be divided into two groups: carriers and channels. Across the lipid bilayer, both create continuous protein routes. Solute flow through channel proteins is always passive, in contrast to the active or passive nature of transport by carriers.

The chance that the rabbits will show the black trait is likely to be low, as the recessive pigment gene is only active at temperatures below 25° Celsius.

The temperature affects the expression of the recessive pigment gene in Himalayan rabbits by determining whether or not the gene is active. At temperatures below 25 ° Celsius, the gene is active and codes for the production of an enzyme that darkens the fur on the nose, ears, and feet, resulting in the black coloration. At higher temperatures, the gene is not active and the enzyme is not produced, leading to the expression of the normal coloration. So the black trait is only present when the temperature is below 25 °C and is not expressed at higher temperatures.

During catabolism, the enzyme breaks bonds in large molecules composing smaller molecules as products. In the image, Catalase is the enzyme, H₂O₂ is the large molecule, and H₂O and O₂ are the smaller  product molecules.

In metabolic reactions mediated by enzymes, the substrates turn into products faster than they would naturally do.

Enzymes act as catalyzer molecules to accelerate natural reactions.

There are two main types of metabolic reactions mediated by enzymes,

Catabolism is the process through which a large molecule is broken into simpler smaller molecules. The enzyme gets in contact with the substrate and breaks it apart into pieces.

Enzymes have specific active sites to which the substrate binds.

Once these large molecules join through these binding sites, they compose the enzyme-substrate complex.

The enzyme turns the substrate into smaller product molecules.

Finally, these smaller molecules are released into the environment.

In the image, we can see this sequence of events.

1) The large molecule is H₂O₂ that binds catalase by its active site.

2) Both of them together compose the H₂O₂-catalase complex (enzyme-substrate complex).

3) Catalaze breaks down H₂O₂ producing H₂O and O₂.

4) Finally, H₂O and O₂ are released from the enzyme binding site.

The function of primers positioned on the dna strand by primase are the starting point for DNA synthesis.

DNA replication is a process of doubling the DNA chain that occurs in the S phase of the cell cycle before mitosis, assisted by the enzyme DNA polymerase. DNA polymerase forms new DNA strands by extending oligonucleotides assisted by primase enzymes. The existing DNA strand that is elongated during this replication is called the primer.

Primers are the existing DNA strands that are elongated during replication. These primers consist of 5-10 DNA nucleotides and work as a starting point for DNA synthesis. In strands that have the 3' end open at the replication fork, primer is only added to the end of this strand.

The ratio of energy the student uses when walking and biking is Ew/Eb = 3

Someone who is walking or running has kinetic energy in it. Kinetic energy is the energy possessed by an object because of its motion or the energy in moving objects.

Speed of walking = Vw

Speed of roading bike = Vb

Given Vb = 3Vw

The power used in both cases is the same to cover the distance.

So, Pw = Pb

Energy used while walking = Ew

Energy used while roading bike = Eb

Force while walking = Fw = Ew/d

Force while walking = Fb = Eb/d

So,

        Pw = Pb

EwVw/d = EbVb/d

  Ew/Eb = Vb/Vw

  Ew/Eb = 3Vw/Vb

  Ew/Eb = 3

Correct question writer:

The power that a student generates when walking at a steady pace of Vw is the same as when the student is riding a bike at Vb = 3Vw. The student is going to travel a distance d. The energy the student uses when walking is Ew. The energy the student uses when biking is Eb. The ratio Ew/Eb is.

DNA mutations occur in the genetic material of an organism, specifically in the DNA sequence. The shape of the extracellular portion of a protein is determined by the amino acid sequence of the protein, which is encoded by the DNA. A change in the DNA sequence can result in a change in the amino acid sequence and therefore the shape of the protein, but the mutation would be located in the DNA, not in the extracellular portion of the protein.

It's important to note that a change in the shape of extracellular portion of a protein, can have various effects on the protein activity, stability, and interactions with other molecules, but the change would occur after the protein is translated from the DNA, not in the DNA itself.
