RNA is a molecule with characteristics and a role similar to DNA. Why is RNA necessary for DNA to fulfill its function?
a. DNA does not contain all the genetic material necessary for a living organism
b. DNA cannot leave the cell’s nucleus, so RNA is needed to bring the code to protein-producing organelle.
c. RNA contains the instructions for how an organism functions and DNA contains the instructions for creating the physical structures of an organism.
d. RNA acts as a checkpoint to ensure that DNA’s code does not contain errors.
Answer:
Transcription and translation are the means by which cells read out, or express, the genetic instructions in their genes. Because many identical RNA copies can be made from the same gene, and each RNA molecule can direct the synthesis of many identical protein molecules, cells can synthesize a large amount of protein rapidly when necessary. But each gene can also be transcribed and translated with a different efficiency, allowing the cell to make vast quantities of some proteins and tiny quantities of others (Figure 6-3). Moreover, as we see in the next chapter, a cell can change (or regulate) the expression of each of its genes according to the needs of the moment—most obviously by controlling the production of its RNA.
Explanation:
RNA is a molecule with characteristics and a role similar to DNA. RNA necessary for DNA to fulfill its function because RNA is needed to bring the code to protein-producing organelle.
What is tRNA ?t RNA is the transfer RNA which brings up messages to code for a particular type of protein via the message carried by the m RNA after which the amino acid chains start gets forming.
A triplet codon is produced where three of the nucleotides bind together to form a particular type of a protein.
Rna has a machinery for the messages transferred as it will channel information to tRNA where on the ribosomal unit it will start synthesising a particular kind of amino acid.
RNA contains the instructions for how an organism functions and DNA contains the instructions for creating the physical structures of an organism.
Therefore, RNA is important as well.

The fossil record indicates that in some cases reasonably well-defined species appear suddenly and remain unchanged for a long time before they become extinct. This phenomenon is referred to as
Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.
This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.

C) 650°C
B) 900°C
D) 20°C
The average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.
What is the average temperature?An average temperature may be defined as the annual mean temperature of any geographical location which is estimated approximately by the average temperature of the maxima and minima for the warmest and coldest months of the year.
It is the principle that the increase in the depth below the surface of the earth ultimately leads to the rising of average temperature. This is due to the process of apparent heat.
It may be possible that higher or lower temperatures also occur. but the average temperature at depth of 10 km of earth surface should approximately remain 200°C. It is a factual type of question.

Explanation:
Undersea vents called black smokers release superheated, mineral-rich water. Light does not penetrate the water, making photosynthesis impossible. However, diverse communities of organisms exist around black smokers at depths of 2100 m below the ocean surface.
Which is the most likely reason these diverse communities can exist so deep in the ocean?
Group of answer choices
Black smokers are warm like tropical land areas.
Black smokers produce sulfur that blocks light and creates a good hideaway for many organisms.
Dead organisms that serve as bacterial food sources drift down from water close to the surface.
Producer organisms use minerals in the water to make food through chemosynthesis.
Answer: Producer organisms use minerals in the water to make food through chemosynthesis.
Explanation:
The producer organisms that exist around these underwater vents are able to produce food through an alternative process to photosynthesis known as Chemosynthesis.
With Chemosynthesis, producer organisms use the minerals in the water from black smokers by converting molecules that contain carbon to organic matter by using energy they acquired from oxidizing ferrous ions and other inorganic compounds.

parent passes copies of all of its
genes to each of its offspring.
When is asexual reproduction in
plants advantageous?
F. when the environment is

G. when there is little competi-
tion for resources
H. when plants are well adapted
to the environment
I. when there are multiple dis-
ease agents in the environment
Asexual reproduction in plants is advantageous when plants are well adapted to the environment that is present in Option H, as plants that are well adapted to their environment are more likely to produce offspring that can thrive in that environment as well.
What is asexual reproduction?Asexual reproduction allows for the efficient production of genetically identical offspring without the need for finding a mate or investing energy in gamete production, and this can be particularly advantageous in stable environments where there is little change and plants can thrive without the need for genetic diversity. In plants, asexual reproduction can occur through various means, including vegetative reproduction, where new plants are produced from parts of the parent plant such as stems, leaves, or roots.
Hence, asexual reproduction in plants is advantageous when plants are well adapted to the environment that is present in Option H.

Researchers isolated a yeast phosphofructokinase mutant in which a serine at the fructose-2,6-bisphosphate (F26BP) binding site was replaced with an aspartate residue. The amino acid substitution completely abolished the binding of F26BP to PFK. There was a dramatic decline in glucose consumption and ethanol production in the mutant compared to control yeast.
Required:
a. Propose a hypothesis that explains why the mutant PFK cannot bind F26BP.
b. What does the decline of glucose consumption and ethanol production in the yeast reveal about the role of F26BP in glycolysis?
Answer:
Explanation:
a.
Phosphofructokinase-1, also known as the glycolysis stimulator, is among the most important glycolysis regulatory enzymes. It's an apoptotic enzyme with effectors (activators/inhibitors) that control its activity. Fructose 6-phosphate and ATP are converted to fructose 1,6-bisphosphate and ADP by PFK-1.
Suppose the serine in PFK's active site is substituted with aspartic acid, the enzyme's active site would be devoid of phosphorylation sites. The enzyme PFK contributes to the transferase family since it has kinase activity. It serves as an acceptor by transferring phosphorus groups to an alcohol group (serine).
Insulin stimulates protein phosphatase, which eliminates the phosphate group from the serine residue, stabilizing the kinase role and promoting F26BP formation. The phosphorylation reaction will not take place provided the serine is substituted with aspartic acid. Therefore, the PFK's kinase activity will be lost. Similarly, F26BP will not form PFK, and it will not be aborted in the future.
b.
Their decline reveals that:
F26BP increases the overall net flow of glucose by glycolysis modulates PFK production and induces Fructose 1,6 bis phosphatase, which also catalyzes the glycolysis reverse process.
Fructose-2,6-bisphosphate transcriptionally activates the rate-limiting process of glycolysis catalyzed by PFK 1.
Increased levels of Fru-2,6-P2 located in the liver raise PFK1's propensity and resistance for fructose 6 phosphate while lowering its affinity for its' inhibitors ATP and citrate.
Fructose 2,6-bisphosphate supersedes the inhibition of ATP and promotes greater sensitivity of the eukaryotes to be regulated by hormones (glucagon and insulin).

How do you think Earth manages to have a continuous supply of oxygen, carbon dioxide, and nitrogen when they are constantly used by living things?
Answer:
It's all a part of a very complex cycle… one thing feeds into another making an almost infinite loop.
The problem with the existence of humans is that we are interrupting the cycle by pumping out carbon dioxide at unsustainable rates. Nitrogen based fertilizers are causing massive algal blooms causing fish die offs on unprecedented scales… but I digress.
Long story short: the Earth is a biosphere with a beautiful balance that it seems humans seem dead set (pun intended) to throw out of harmony into chaotic turmoil.
Explanation:
because yes
Earth manages to have a continuous supply of oxygen, carbon dioxide, and nitrogen when they exist constantly utilized by living things because it exists as part of a complex cycle named the nutrient cycle.
What is meant by nutrient cycle?The soil's minerals, decomposing leaves and wood, water from snowfall and rain, as well as species that live above and below ground (the soil is alive! ), all contribute to the nutrient cycle. Trees and other plants take up nutrients from the soil, both mineral and non-mineral, through their roots.These nutrients are kept in reserve by plants in their leaves, flowers, and other parts. When animals eat plants, the nutrients either go back to the ground or are delivered to the animals.Arthropods, earthworms, fungi, and bacteria in the soil break down dead plants and animals. The decaying matter is ground up and combined with the soil by arthropods and earthworms.Some of the more complicated substances can be disassembled and divided into smaller parts by fungi.To learn more about the nutrient cycle, refer to:

temperature usually increase when water condenses. which behavior of water is most directly responsible for this phenomenon?
Answer:
the release of heat by the formation of hydrogen bonds.
Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Condensation can be defined as a process which typically involves the change in the physical state of matter from the gaseous phase into a liquid phase i.e water changing from gas (vapor in the air) into a liquid form.
Temperature usually increase when water condenses. This phenomenon is as a result of the release of heat (exothermic reaction) by the formation of hydrogen bonds in water i.e hydrogen-hydrogen bond in water molecules formed by the chemical elements; oxygen and hydrogen.

The crossed extensor reflex is a type of motor response that occurs to tactile stimulation of a lower limb. This, like other reflexes, is an indication of the proper integration and development of the central nervous system.
Explanation:
Stimulation on one side of the body can produce, in addition to the ipsilateral response. The crossed extensor reflex is a type of motor response, reciprocal innervation is involved: the flexor muscles of the stimulated limb contract at the same time that the extensors of said limb are inhibited. Coupled with flexion of the stimulated limb, the reflex produces an opposite effect in the contralateral limb: the extensor muscles are activated and the flexors are inhibited, this cross-extension reflex increases postural support during withdrawal of the painful stimulus.
