1. Raul has scraped his knee and noticed that after a week it had almost completely healed. Raul wondered how the skin was able to repair itself while looking exactly the same as his non-injured skin. In 3-5 sentences explain how mitosis plays a role in healing skin after injury and is able to maintain the look of the existing, non-injured skin
Injured skin produces C-rays that allow for skin to knit itself back together. These C-rays are always present in cells, but are only activated during mitosis by injured skin. This is why there is sometimes scarring left after injury, as the C-rays are not activated as much as healing occurs.
2. In three to five sentences, explain the advantage of keeping some DNA needed by mitochondria in the cell’s nucleus and some in the mitochondria itself.
Mitochondrial DNA is the small circular chromosome present inside the cell organelle called mitochondria used for energy production. This type of DNA passes from the mother to the offspring. Mitochondrial DNA (mtDNA) has several advantages over nuclear DNA (nDNA):for species identification purposes including a higher copy number a lack of sequence ambiguities from heterozygous genotypes .a faster rate of mutation
3. In 3–5 sentences, construct a summary of the process of gene expression, starting with DNA and ending with proteins
The process of gene expression starts with the transcription of the genetic information in the DNA into genetic codes in the form of messenger RNA.
The messenger RNA then undergoes some processing such as modification of tails and removal of non-coding sequence before the genetic codes are translated to their respective amino acids in a process known as translation.
The amino acids are linked together by peptide bonds and the resulting primary protein structure is folded in specific ways depending on their functions.
Mitosis takes one cell and replicates it into two genetically identical cells. Thus, the correct option for this question is A.
What is Mitosis?Mitosis may be defined as a type of cell division through which each parental cell is typically divided into two daughter cells. These daughter cells are genetically identical to the parental cell and are mostly diploid in nature.
On contrary, meiosis is another type of cell division in which each parental cell is divided into four daughter cells which are genetically unique to the parental cell. These daughter cells are haploid in nature. This type of division is known as reductional division. It occurs in the germ cells of organisms.
Therefore, mitosis takes one cell and replicates it into two genetically identical cells. Thus, the correct option for this question is A.

SECTION B: QUESTION 2 2.1 The diagram below shows part of the human ear. 2.1.1 2.1.2 2.1.3 2.1.4 E A B C Explain the consequence if structure E lost its flexibility. Describe the process of hearing. D 2.Z Identify structures A and B Give the LETTER and the NAME of the parts that: (a) equalises pressure on both sides of the tympanic membrane (b) absorbs excess pressure waves from the inner ear (2) (2) (2) (2) (7) (15)
Answers
If structure E (stapes) lost flexibility, it would impair sound transmission, leading to hearing sensitivity.
Process of hearing: Sound waves enter the ear, vibrate the eardrum (tympanic membrane). Ossicles (A: malleus, B: incus) amplify vibrations to inner ear. Vibration of fluid in cochlea stimulates hair cells, converting to electrical signals for interpretation.
Structure A: Malleus
Structure B: Incus
(a) Structure C (eustachian tube) equalizes pressure on both sides of the tympanic membrane.
(b) Structure D (round window) absorbs excess pressure waves from the inner ear.
If structure E, which is the ossicles (specifically the malleus, incus, and stapes), lost its flexibility, it would have a significant consequence on hearing. The ossicles play a crucial role in the process of sound transmission. They amplify sound vibrations that enter the ear through the outer ear and transfer them to the inner ear. The flexibility of the ossicles allows them to vibrate in response to sound waves, transmitting these vibrations to the fluid-filled cochlea in the inner ear.If structure E lost its flexibility, the transmission of sound vibrations would be impaired. This would result in a reduced ability to perceive and interpret sound. Hearing sensitivity would be significantly compromised, and sounds may appear muffled or distorted. It may become challenging to distinguish different pitches or understand speech clearly.The process of hearing involves several steps. When sound waves enter the outer ear, they travel through the ear canal and reach the eardrum (tympanic membrane). The vibrations of the eardrum are then transferred to the ossicles (structures A and B in the diagram), which amplify and transmit the vibrations to the cochlea (structure C). The cochlea is responsible for converting the mechanical vibrations into electrical signals that can be interpreted by the brain. These signals are then sent to the brain via the auditory nerve, where they are processed and perceived as sound.Structure A, known as the Eustachian tube, equalizes pressure on both sides of the tympanic membrane. It connects the middle ear to the back of the throat, allowing air to flow in and out, maintaining equal pressure on both sides of the eardrum.Structure B, called the round window, acts as a pressure relief valve. It absorbs excess pressure waves from the inner ear, preventing damage to delicate structures by allowing fluid in the cochlea to move in response to the sound vibrations.Overall, the ear is a complex and intricate system that relies on the interaction of various structures to enable the sense of hearing.For more such questions on Hearing sensitivity:

Hearing involves a process of sound wave transduction through the tympanic membrane and ossicles. If the tympanic membrane (E) loses its flexibility, sound quality may diminish. The Eustachian tube and cochlea serve to manage pressure within the ear.
Explanation:The process of hearing (audition) involves the transduction of sound waves into a neural signal. When the tympanic membrane (structure E in your diagram), or eardrum, is struck by sound waves, it vibrates. These vibrations are then transferred to the ossicles, which are three small bones in the middle ear. The ossicles are identified as structures A (Malleus or Hammer) and B (Incus or Anvil) in your diagram. Sound waves are finally transduced into a neural signal in the inner ear.
If the tympanic membrane was to lose its flexibility, it would not vibrate as effectively when struck by sound waves. This could diminish the quality of sound and potentially lead to hearing loss.
The Eustachian tube equilibrates air pressure on both sides of the tympanic membrane. This would be your answer to part (a) of the lettered question. Part (b) refers to the role of the cochlea in the inner ear, which helps to absorb excess pressure waves from the inner ear.

a. Viruses reproduce using a ______ _____.
b. What are the differences between proviruses and viral DNA?
c. Why is the common cold virus so difficult to cure?
Answers
Answer:
Viruses reproduce using a host cell
The differentce between proviruses and viral DNA is A provirus is a virus genome that is integrated into the DNA of a host cell. In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages. However, it is important to note that proviruses are distinctly different from prophages and these terms should not be used interchangeably.
Common cold virus is difficult to cure because Unfortunately, antibiotics — medications that treat bacterial infections — cannot treat or cure a common cold. That's because colds aren't caused by bacteria. Some people report that they've had a cold, took antibiotics, and felt better after a few days of the medication.
Explanation:
Currently, the world population is approximately seven billion people. About 20 percent of the world's current population lives in China. If China experiences a 5 percent decline in population in cach of the next five years, and if the rest of the world experiences a 2 percent growth in population in each of the next five years, at the end of the five-year period, what percentage of the worid's population will live in China? (You may round your answer to the nearest percent.)
Hint: First calculate the actual numeric figures of the current population of China (20 percent of 8 billion) and also the current population of the rest of the world (80 percent of 8 billion). Then apply the rates of dealine to "China's population figure" and the rate of growth to "the rest of the world's population figure" before calculating your final answer.
Answers
At the end of the five-year period, approximately 14 percent of the world's population will live in China.
To solve this problem, we first calculate the current population figures for China and the rest of the world.
Since 20 percent of the world's current population lives in China and the world population is approximately seven billion, the current population of China is 20 percent of seven billion, which is 1.4 billion.
The population of the rest of the world can be calculated as 80 percent of seven billion, which is 5.6 billion.
Next, we apply the decline and growth rates to the respective population figures over the five-year period.
For China, a 5 percent decline in population each year for five years means multiplying the current population figure by (1 - 0.05) five times, resulting in a final population of approximately 1.07 billion.
For the rest of the world, a 2 percent growth in population each year for five years means multiplying the current population figure by (1 + 0.02) five times, resulting in a final population of approximately 6.4 billion.
To find the percentage of the world's population that will live in China at the end of the five-year period, we divide China's final population by the sum of China's final population and the rest of the world's final population.
This gives us (1.07 billion / (1.07 billion + 6.4 billion)) \(\times\)100, which is approximately 14 percent.
Therefore, at the end of the five-year period, approximately 14 percent of the world's population will live in China.

Reciprocal cross is basically a technique which used in genetics in order to determine whether a trait is sex-linked or it is autosomal. In a reciprocal cross, two different crosses are performed. The first one with the male parent having the trait of interest and the female parent which is not having that trait. The second cross is done with the female parent having the desired trait and the male parent not having the trait.
If the trait is found to be autosomal, the results of the two crosses will be the same but if the desired trait is sex-linked, the results will differ depending on which sex carries the trait.
