Answer:
A. Cell division
Explanation:
What is mitosis? Mitosis is a type of "cell division" in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.
Of all the types of chromosomal mutations you have studied in this lesson, only one does not lose the genetic information of the chromosome. Which one is it? Explain the impact of this mutation?
Answer:
In biology, a chromosomal mutation is the mutation of the chromosomal segments of the DNA strands. This can occur when the number of chromosomes or chromosome sets (ploidy) increases or decreases in a genome as well as when changes in chromosomes structure occur. Irregularities or accidents when cell division happens as well as during chromosomal crossing over or fertilization can all be causes of chromosomal mutation.
All types of chromosomes can undergo chromosomal mutation. Chromosomal mutation examples include chromosome deletion, duplication, inversion, and translation. These are known to cause different kinds of genetic and chromosomal mutation diseases.
For instance, chromosomal mutations on chromosome 4 have been investigated and proven to be the source of numerous genetic disorders and even cancer in humans. This includes conditions like narcolepsy and Parkinson’s disease.

what is the function of primers positioned on the dna strand by primase?
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.

A recessive pigment gene in Himalayan rabbits is only active at temperatures below 25 ° Celsius, turning the fur on the nose, ears, and feet black. A population of rabbits with the Himalayan trait is introduced into a new area where low temperatures are around 30 ° Celsius.
What is the chance that the rabbits will show the black trait? Enter the answer in the box.
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.
How does the temperature affect the expression of the recessive pigment gene in Himalayan rabbits?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.

Why do you think it is necessary to cover the fossils in plaster?
Covering fossils in plaster is a common technique used to protect and preserve them. The main reason for covering fossils in plaster is to stabilize and protect the fossil from further deterioration. Fossils are often found in fragile and delicate states, and plaster provides a protective layer that helps to prevent further erosion or damage caused by exposure to the elements or handling. Plaster also provides a hard, durable surface that makes it easier to transport and handle the fossils without causing additional damage.
Additionally, the plaster can be used to make a mold of the fossil. This allows for a replica to be made which can be used for research, study or display, without risking damage to the original fossil.
Finally, plaster is also useful for reconstructing missing or broken parts of the fossil, which can make it easier to study and interpret the fossil.
In summary, covering fossils in plaster is necessary to protect and preserve them, to make a replica, and to reconstruct missing or broken parts.

Which greenhouse gas is released from burning fossil fuels?
Answer: Carbon Dioxide
Explanation:
Carbon dioxide is the greenhouse gas which is released from burning fossil fuels.
Greenhouse gases are gases capable of absorbing infrared light and trapping heat in our atmosphere. Greenhouse gases cause the greenhouse effect or global warming.
The greenhouse gases are so named because their action is comparable to how glass walls trap heat inside a greenhouse. Carbon dioxide is the principal greenhouse gas generated by the combustion of fossil fuels, but tiny quantities of nitrous oxide and methane are also emitted.
Fossil fuels consist of coal, oil, and gas. Hydrocarbon molecules serve as the foundation for these fuels. As a result, when these fuels are burned, carbon dioxide is released. Some fossil fuels contain components that emit nitrous oxide or methane.

Cloning is a powerful tool used in biotechnology, and it has numerous applications in medicine, agriculture, and other areas. Cloning can be used to create genetically identical animals, plants, and even humans.
Pluripotent cells are stem cells that are capable of becoming any other type of cell in the body. This means that they have the ability to be reprogrammed into any other cell type, including those that make up an egg cell. This ability to be reprogrammed makes them ideal for cloning, as scientists can take a pluripotent cell and use it to create an egg cell that is genetically identical to the original cell.
