Answer:

Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.

Explanation:

Answer:

In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. ... Researchers refer to DNA found in the cell's nucleus as nuclear DNA.

Answer:

Final temperature, T2 = 2460 Kelvin.

Explanation:

Given the following data;

Initial pressure = 1atm

Final pressure = 2.7atm

Initial temperature = 911K

To find the final temperature, we would use Gay Lussac's law;

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

[tex] PT = K[/tex]

[tex] \frac{P1}{T1} = \frac{P_{2}}{T_{2}}[/tex]

Making T2 as the subject formula, we have;

[tex] T_{2}= \frac{P_{2}}{P_{1}} * T_{1}[/tex]

Substituting into the equation, we have;

[tex] T_{2}= \frac{2.7}{1} * 911[/tex]

[tex] T_{2}= 2.7 * 911 [/tex]

Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.

Answer: The nearby nerve that can be affected by this tumour is the FACIAL NERVE.

Explanation:

As stated in the question, the acoustic neuroma is a tumor that arises from the vestibular portion of the vestibulocochlear nerve which is the VIII ( 8th) cranial nerve.

VESTIBULOCOCHLEAR NERVE: These nerves are composed of two distinct sets of fibres, vestibular nerves and cochlear nerves.

The vestibular nerves arise from the semicircular canals of the inner ear and convey impulses to the cerebellum. They are associated with the maintenance of posture and balance. The cochlear nerves originate in the spiral organ in the inner ear and convey impulses to the hearing areas in the cerebral cortex where sound is perceived.

The Facial nerve, also called the 7th cranial nerve, which are the motor fibres that supply the muscles of facial expression. It lies adjacent to the vestibulocochlear nerve as they pass through the internal auditory canal which is located at the petrous part of the temporal bone. As the tumor grows, the facial nerve would be affected because it's the closest nerve to the VESTIBULOCOCHLEAR nerve..

3.You might think this should mean you need to cut out salt completely, but salt is actually an important nutrient for the human body. Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.

4.Cooling the mixture is to prevent the DNA from being degraded by the heating.

5.The ethanol pulls water from the DNA molecule so that it then collapses in on itself and precipitates. The DNA will become visible as white mucous strands that can be spooled with the wooden applicator stick.

6.The colder the ethanol is the greater the amount of DNA that is precipitated. (You could try having some of the students use room temperature ethanol and see if the amount of DNA they can spool is the same or less than that for the groups using the ice-cold ethanol.

7.The reason is every strawberry seed contains different genetic material, the product of a myriad of potential gene combinations. Because the genetics of strawberries are so diverse (humans are diploid, strawberries are octoploid)

С  observation

Explanation:

This mode of investigation is an example of observation.

Observations are carried out using our senses and keen inquisitiveness. It can take place within a short period of time or an extended duration.

So; noticing the change in shape of the salamanders is making an observation.

Our sight, smell, taste e.tc are all observational tools.

Answer:Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Soap has chemicals that kill bacteria

When you wash your hands with soap and water, you surround any microorganisms on your skin with soap molecules. The hydrophobic tails of the free-floating soap molecules attempt to evade water; in the process, they wedge themselves into the lipid envelopes of certain microbes and viruses, prying them apart.

Uranus, like Earth, has four seasons. ... For starters, the length of Uranus' seasons are different from ours. It takes Earth 365 days to orbit around the sun, but it takes Uranus 84 Earth-years, more or less. So Uranus' year is 84 Earth-years along, and each season on Uranus lasts 21 earthly years.

Answer:

a

Explanation:

The phenotypic ratio is the depiction and the relation of the occurrence of the phenotype in the offspring. The phenotypic ratio of 9:4:3 indicates codominance. Thus, option A is correct.

Codominance is the inheritance where both the recessive and the dominant allele are expressed in the offspring independently to produce the individual with the expression of both the trait separately.

The blood group, eye color, roan cattle, flower colors, sickle-cell anemia, etc., are some examples that show the pattern of codominance. The phenotypic ratio suggests the occurrence of the physical traits in the offspring that are visible.

In codominance, the phenotypic ratio is 9:4:3 as both the traits possessing alleles are independently expressed in the next generation.

Therefore, 9:4:3 is the phenotypic ratio of codominance.

The soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).

Soil is also defined as earth or dirt which is a mixture of organic matter, minerals, gases, liquids and organisms which together support life. These are distinguished from silt by restricting the former term specifically to displaced soil.

It provides many important services for both people and the planet by putting food on our plates, purifying our water, protecting us from floods and combating drought. Soil is also important in combating climate change because it captures and stores large amounts of carbon. Without healthy soil there is no food security.

Whereas growing the same crop year after year reduces the availability of certain nutrients and depletes the soil. Monoculture leads to soil exhaustion when the soil becomes deficient in these nutrients.

Thus, the soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
