Answer:
Argon 38 has 18 proton and 20 neutron
Argon 40 has 18 proton and 22 neutron
Explanation:
isotope is same no of proton diff no of neutron
Both argon-38 and argon-40 have 18 protons but they have different atomic masses. The atomic mass of argon-38 is 38u while the atomic mass of argon-40 is 40u. Thus, they are isotopes.
What are isotopes? Some atoms contain the same number of protons (i.e. same atomic number) but they have a different number of neutrons (i.e. different mass numbers). These types of atoms are called isotopes.Argon element has three isotopes namely, argon-36, argon-38 and argon-40. All the three isotopes of argon have the same number of protons i.e. 18. But, all have different numbers of neutrons and thus, different mass numbers. Argon-36 has 18 neutrons, argon-38 has 20 neutrons and argon-40 has 22 neutrons. Thus, the mass numbers of argon-36, argon-38 and argon-40 are 36u, 38u and 40u respectively.Thus, the structure of an atom of argon-38 and argon-40 is slightly different as they are isotopes. Argon 40 has more atomic mass than argon-38. But, both contain the same number of protons. They have similar chemical properties but different physical properties.

In a deciduous forest of Maine, there are 300 Falcons living in a certain region at the beginning of the year. Scientists have determined that these Falcons demonstrate exponential growth and that their per capita growth rate is 0.067. What will the population of Falcons be in 5 years?
Answer:
419 Falcons
Explanation:
P= Poe^rt
P= population at time t = ?
Po = initial population = 300
r= growth rate = 0.067
t = time taken = 5 years
P = 300e^(0.067 * 5)
P = 419 Falcons

DNA polymerase only travels in the__________to________direction.
Answer:One Direction
DNA Polymerase Only Moves in One Direction
Explanation:
After a primer is synthesized on a strand of DNA and the DNA strands unwind, synthesis and elongation can proceed in only one direction. As previously mentioned, DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered.

Use the image below to explain protein synthesis and the steps of transcription and translation. Hint: Use the numbers 3-11 to guide your explanation.
Answer:
Protein synthesis is the process in which cells make proteins.It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein.

why are manure better than fertilizers
Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

Answer:
transpirationExplanation:
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

The subconscious psychological meaning of a dream is its latent substance. This symbolically veiled content may be painful or traumatic. Therefore, option (B) is correct.
What is latent content of dream?In Freudian dream analysis, content refers to both the Latent and manifest elements of a dream, or both the overt meaning of the dream and the dream as it is remembered. Dreams represent the uncontrollable mental events that occur during various stages of sleep.
The hidden psychological significance of a dream is its latent content. Because it could be distressing or traumatic, this content frequently makes symbolic appearances in disguise and contains things that are hidden from conscious awareness.

The figure above depicts the DNA-protein complex that is assembled at the transcriptional start site of gene X when the expression of gene X is activated in liver cells. Previous studies have shown th gene X is never expressed in nerve cells. Based on the diagram, which of the following most likely contributes to the specific expression pattern of gene X?
A.Expression of gene X produces large amounts of tRNA but undetectable amounts of mRNA.
B The general transcription factors inhibit the activation of gene X in liver cells by blocking the activator from binding to RNA polymerase II.
С The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues.
D The enhancer is a unique DNA segment that is added to the nuclear DNA of some cells of an organism during the process of mitotic cell division but not other cells.
Answer:
C
Explanation:
The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues. The correct option is C.
What is gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Because a particular protein can only be made when its gene is turned on, gene expression is significant.
However, there are several steps involved in translating a gene into a protein, and one of these steps—the creation of proteins—is crucial in the gene expression pathway that can be changed in cancer.
According to the diagram, the activator is a DNA-binding protein that only binds to certain sequences in select tissues.
Thus, the correct option is C.

What is the main difference between the intertidal zone and the neritic zone?
the amount of exposure to sunlight
the amount of salt in the water
the amount of time covered by water
the presence of plants and animals
Answer:
intertidal zone is the area of shore between the high tide and low tide lines whereas neritic zone is the area of the ocean from the low tide line out to the continental shelf.
The main difference between the intertidal zone and the neritic zone is the amount of time covered by water.
What is intertidal zone and the neritic zone?The intertidal zone is the area of the shoreline that is regularly exposed to air at low tide and submerged at high tide. This area is characterized by its exposure to fluctuations in water level, temperature, and salinity, and is home to a diverse range of organisms that have adapted to these conditions.
The neritic zone, on the other hand, is the shallow ocean water over the continental shelf, extending from the low tide mark to a depth of about 200 meters. Unlike the intertidal zone, the neritic zone is always covered by water and is characterized by relatively stable physical conditions, including a relatively constant temperature and salinity.
While the amount of exposure to sunlight can vary in both the intertidal and neritic zones, the main difference between these two habitats is the amount of time covered by water and the resulting stability of environmental conditions.
