Heres a few questions

Answer:

Enzyme

Explanation:

Enzymes are the bio-catalyst that serve to accelerate the metabolic reactions occurring in a living cell.  All the metabolic reactions of organisms are catalyzed by enzymes. Each metabolic reaction is catalyzed by specific enzyme. Absence of that particular enzyme leads to absence of the respective product. Since genes code for protein which regulate the specific trait, absence of enzyme does not allow the expression of that trait.

Example: Absence of enzymes for chlorophyll synthesis would lead to absence of chlorophyll from leaves of the green plants.

Answer:

Medicines is a high possibility, but agriculture is a yes.

Explanation:

Answer: The correct options are statement first and fourth that is -

It is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction

Explanation: Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA.

The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.

Answer:

It is synthesized in the 5′ to 3′ direction.

It is synthesized toward the replication fork.

Answer: the answer is a

Explanation:

Answer: Option A

Explanation:

The plant organs that is always included in the root system is roots.The root system in the plants consists of the structures that are below the ground.

Such structures are tubers, roots, rhizomes, et cetera. The main function of root system is to supply water, hormones, minerals to the plant and within the plant.

The roots also provide anchorage to the plants by binding tightly to the soil particles.

Answer:

1. Transcription – conversion of DNA to RNA

2. Post-transcriptional modifications

3. RNA transport

4. Translation or protein synthesis

5. Protein folding

1 Initiation. The DNA molecule unwinds and separates to form a small open complex. RNA polymerase binds to the promoter of the template strand.

2 Elongation. RNA polymerase moves along the template strand, synthesising an mRNA molecule. In prokaryotes RNA polymerase is a holoenzyme consisting of a number of subunits, including a sigma factor (transcription factor) that recognises the promoter. In eukaryotes there are three RNA polymerases: I, II and III. The process includes a proofreading mechanism.

3 Termination. In prokaryotes there are two ways in which transcription is terminated. In Rho-dependent termination, a protein factor called "Rho" is responsible for disrupting the complex involving the template strand, RNA polymerase and RNA molecule. In Rho-independent termination, a loop forms at the end of the RNA molecule, causing it to detach itself. Termination in eukaryotes is more complicated, involving the addition of additional adenine nucleotides at the 3' of the RNA transcript (a process referred to as polyadenylation).

4 Processing. After transcription the RNA molecule is processed in a number of ways: introns are removed and the exons are spliced together to form a mature mRNA molecule consisting of a single protein-coding sequence. RNA synthesis involves the normal base pairing rules, but the base thymine is replaced with the base uracil.

D. volcano: the eruption creates new land on the Earth's crust

Explanation:

The volcanic activity is crucial for the formation of new crust on the planet, be it oceanic or continental one. Through the eruptions, the volcanoes release pyroclastic material, and more importantly and in much higher amounts, they release lava. The lava quickly starts to cool off on the surface of the Earth as the temperature is much lower. As it cools off, the lava becomes igneous rocks, more specifically extrusive igneous rocks. These new rocks are actually the new crust on the Earth's surface, thus increasing the land mass.

answer is D) a virus cannot reproduce itself without a host cell.

Final answer:

The bacteria that cannot survive when brought to the surface and exposed to air can be described as strict anaerobes. They lack cellular defenses against oxidative stress and need anaerobic conditions to survive. In deep ocean sediments, where no oxygen is present, they can thrive.

Explanation:

The bacteria that cannot survive when brought to the surface and exposed to air can be described as strict anaerobes. These bacteria live in environments lacking oxygen and use anaerobic respiration or fermentation to survive. Oxygen can be lethal for them because they lack cellular defenses against oxidative stress. They are able to live deep in the ocean sediments where no oxygen is present, but cannot survive in the presence of oxygen.

Answer:  Blue, green and indigo.

Explanation: The visible spectrum of the electromagnetic radiation includes 7 colors and besides these 7 colors human eye cannot see other colors.

So the blue, green and indigo lies under the visible spectrum. A typical human eye can detect the wavelength from 380 to 740 nanometers.

Before this wavelength and after this wavelength human eye cannot see anything.

The visible spectrum of sunlight includes the colors blue, green, and indigo. Infrared and ultraviolet are part of the wider electromagnetic spectrum, but they are not visible to the human eye. Other species can perceive these ranges that are outside of the human range.

The visible spectrum of sunlight includes the colors we can see, namely: blue, green, and indigo. It's important to understand that the visible spectrum is a portion of the larger electromagnetic spectrum. This visible spectrum, perceived by human eyes, is associated with wavelengths that range from 380 to 740 nm. However, the divisions between infrared, visible, and ultraviolet light, as well as those between the seven rainbow colors (red, orange, yellow, green, blue, indigo, violet), are not distinct. In the context of the question, the components of sunlight that make up the visible spectrum are blue, green, and indigo.

On the other hand, infrared light and ultraviolet light are part of the overall electromagnetic spectrum but are not visible to the human eye. Therefore, infrared and ultraviolet do not make up part of the visible spectrum of sunlight that we can see. Species such as honeybees and some snakes can perceive the ultraviolet and infrared ranges, respectively, which are outside of the human range.

A codon is a group of 3 nitrogen bases on a mRNA molecule that carries the code for a specific amino arid. An anticodon is a set of 3 nitrogen bases on a tRNA molecule that matches a codon on a mRNA molecule.

A codon is a sequence of three nucleotides on mRNA that represents a specific amino acid, while an anticodon on tRNA matches this sequence. The genetic code is the set of rules dictating how codons are translated into proteins. Codons and anticodons play crucial roles in the protein synthesis process.

A codon is a group of 3 nitrogen bases on an mRNA molecule that carries the code for a specific amino acid. Similarly, an anticodon is a set of 3 nitrogen bases on a tRNA molecule that matches a codon on an mRNA molecule. Each codon consists of three nucleotides, usually abbreviated with the letters A, U, G, and C. In the mRNA, uracil (U) is used whereas DNA contains thymine (T). The mRNA molecule instructs a ribosome to synthesize a protein according to the genetic code represented by these codons.

The genetic code is a set of rules by which information encoded in the genetic material (DNA or mRNA sequences) is translated into proteins by living cells. This information is carried by the sequence of codons in mRNA. For example, the codon AUG not only codes for the amino acid methionine but also serves as a start signal for translation. Moreover, there are 64 possible codons, more than the number of amino acids, which allows for some redundancy; several codons can specify the same amino acid. In addition, some codons function as stop signals to end protein synthesis.

Answer:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water

Final answer:

Photosynthesis and cellular respiration work together in the carbon cycle, where plants use carbon dioxide and water to produce glucose and oxygen through photosynthesis, and then the glucose is used in cellular respiration to produce ATP along with the release of carbon dioxide and water.

Explanation:

Photosynthesis and cellular respiration are two processes that work together to store and release energy in living organisms. An example of how they work together is through the carbon cycle. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The glucose produced is then used in cellular respiration to produce ATP, and in the process, carbon dioxide and water are released as byproducts. This cycle ensures the continuous recycling of carbon and the availability of oxygen for organisms.

A reasonable solution to this problem might consider all but only Growing farm crops in greenhouses instead of on land previously home to teak trees.

The tick plant is called as king of timbers. It grows as a very huge tree and provides excellent quality wood. Its wood is mainly used in making furniture.

Teak is prized hardwood and is used for outdoor furniture. Teak is grown in only a few locations throughout the world and is a native tree becoming scarce due to repeated harvesting.

Logging teak forests disrupts the natural habitat of many other species and it reduces local biodiversity as well. Forests are a reasonable solution to this problem they consider replanting areas where teak has been already harvested.
