Answer: cap and tail
Explanation:
The thing that protects mRNA from attack by cellular enzymes is the cap and tail, which is the third option, as the cap is a modified nucleotide structure that is added to the 5' end of mRNA during transcription.
What are the mRNA cap and tail?Messenger RNA (mRNA) is a type of RNA that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where it is translated into proteins. mRNA molecules are relatively unstable and are subject to degradation by cellular enzymes in the cytoplasm. However, mRNA molecules are protected from degradation by the addition of a cap and tail during transcription. The cap is a modified guanine nucleotide that is added to the 5' end of the mRNA molecule. The cap structure protects the mRNA from exonucleases, which are enzymes that cleave the mRNA from the ends.
Hence, the thing that protects mRNA from attack by cellular enzymes is the cap and tail, which is the third option.

Which step in the nitrogen cycle is responsible for returning fixed nitrogen back into the atmosphere?
_______ is a process in which certain types of bacteria present in the soil convert nitrates into nitrogen gas.
Answer:
Denitrification
Explanation:
Elizabeth is married to John, and they have four children. Elizabeth has a straight nose
(recessive) and is able to roll her tongue (dominant). John is also able to roll his tongue,
but he has a convex (Roman) nose (dominant). Of their four children, Ellen is just like
her father, and Dan is just like his mother. The other children-Anne, who has a convex
nose, and Peter, who has a straight nose-are unable to roll their tongues. Please
answer the following questions about this family.
a. What are the genotypes of Elizabeth and John?
b.
Elizabeth's father was a straight-nosed roller, while her mother was a convex-nosed
non-roller. What can you figure out about their genotypes?
c. John's father was a straight-nosed roller, while his mother was a convex-nosed
roller. What can you determine about their genotypes?
d.
Diagram the three described generations of this family in accepted pedigree form,
including the phenotypes for these two traits.
Humans have a variety of alleles, which together with homologous partners make up the gene loci responsible for specific phenotypes. The geneticist Gregor Mendel discovered a phenomenon known as recessive/dominant, which describes how the effects of one allele can be obscured by those of another.
Given her recessive nose shape and dominant tongue characteristic, we can infer Elizabeth's genotypes from the description to be nnRR and nnRr. Because John has a dominant nose shape and a dominant tongue characteristic, his genotypes may be NNRR, NNRr, NnRR, or NnRr. It is necessary to check the genotypes of their offspring in order to determine their true genotypes. Of their four children, dominant (Ellen and Anne) and recessive (the other three) phenotypes of nose shape exist (Dan and Peter).Elizabeth's mother was a convex-nosed (dominant) non-roller and her father was a straight-nosed (recessive) roller (recessive). According to this description, Elizabeth's mother has the genotypes NNrr and Nnrr, whilst her father could have the nnRR and nnRr. Elizabeth's genotype is nnRr, as shown by the answer in letter a. Her mother and father each contributed one recessive n gene. As a result, Elizabeth's mother is Nn for the N allele. Due to Elizabeth's mother's recessive phenotype, her father's R allele can either be RR or Rr (rr). In conclusion, Elizabeth's mother is "Nnrr" and her father is "nnRR" or "nnRr".While his mother was a convex-nosed (dominant) roller, John's father was a straight-nosed (recessive) roller (dominant). According to this description, John's mother's genotypes are NNRR, NnRR, NNRr, and NnRr, whereas John's father's genotypes are nnRR and nnRr. John has the genotype NnRr, as shown by the response in letter a.If John's father has the genotype nnRR, his mother could have NNRr or NnRr.John's mother's genotype might be NNRR, NnRR, NNRr, or NnRr when his father has the nnRr allele.To know more about Gregor Mendel please click here : https://brainly.com/question/930312

The two copies of each replicated chromosome stay firmly bonded together as identical sister chromatids after the chromosomes are duplicated in the S-phase.
Define cell division in DNA.Cohesins, multisubunit protein complexes that are deposited along the length of each sister chromatid as the DNA is duplicated, are what hold the sister chromatids together. Only in late mitosis does the cohesin between sister chromatids break, which is essential to the process of chromosomal segregation. Until the start of cytokinesis, DNA is compressed. Mitosis and cytokinesis comprise the M phase of cell division. DNA condenses into observable chromosomes during the process of mitosis, which is followed by the division of the chromosomes into two identical sets. The final stage of mitosis, known as cytokinesis, is when the two daughter cells, each of which has a nucleus and cytoplasmic organelles, separate.A cell that enters the M phase contains 4N DNA and divides into two cells with identical 2N DNA complements.To know more about cell division, visit:

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears quickly, thereby altering biogeochemical cycles.
What is a possible beneficial consequence of introducing the earthworms to forests in the Great Lake regions?
A. The earthworm increases the energy flow from one tropic level to the next.
B. The earthworms provide competition for other native, primary consumers.
C. The earthworms burrow, which improves the nutrients, flow of air, and water
underground.
D. The earthworms are secondary consumers that provide another food source for
tertiary consumers.
The earthworms burrow, which improves the nutrients, and flow of air, and water underground. Therefore option C is correct.
The possible beneficial consequence of introducing earthworms to forests in the Great Lakes region is that they can enhance the soil quality and ecosystem functioning through their burrowing activities.
Earthworms are known as ecosystem engineers because their burrowing behavior can have significant impacts on soil structure, nutrient cycling, and water infiltration.
When earthworms burrow through the soil, they create channels and tunnels, which improve the flow of air and water underground.
This increased aeration and drainage can benefit the roots of plants by providing them with better access to oxygen and water, promoting their growth and overall health.
Thus, the burrowing activities of earthworms improve soil structure, nutrient availability, and water infiltration, which can have positive effects on the health and productivity of forest ecosystems in the Great Lakes region.

photosynthesis
6CO₂ + 6H₂0 + energy → C₆H₁₂O₆ + 6O₂
aerobic respiration

Photosynthesis and cell respiration are closely related. Among other aspects to consider, photosynthesis releases oxygen to the environment, while respiration consumes oxygen. Photosynthesis is happening from 0-30 minutes.
How are photosynthesis and cell respiration related?
Photosynthesis and respiration are two complementary processes.
Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria.The photosynthetic process needs solar radiation to produce organic compounds (C₆H₁₂O₆), while the respiration process needs organic compounds (C₆H₁₂O₆) to obtain chemical energy.Photosynthesis transforms CO₂ into organic compounds during the Calvin cycle, while respiration transforms organic compounds into CO₂.Photosynthesis breaks down water molecules, while respiration produces them.In the process of photosynthesis, it occurs a release of oxygen (O₂), which is then used during the respiration process. Both processes are part of the carbon biological cycle.Electron transport chains are present in both processes and are used to capture energy, which will be used in other cellular reactions.Respiration's final products are CO₂, ATP, and water.Photosynthesis' final products are carbohydrates and oxygen release.The information provided before are resumed in the reactions provided on the first page of this text.
Photosynthesis uses solar energy, CO₂, and water to produce carbohydrates (C₆H₁₂O₆) and release oxygen.Respiration uses carbohydrates (C₆H₁₂O₆) and oxygen to produce CO₂, water, and energy (ATP)On the second page, we can see an Oxygen vs Time graph, where the two variables are,
independent variable ⇒ Timedependent variable ⇒ OxygenThis graph shows the evolution with time of oxygen concentration in the air surrounding the Rubric plant.
This graph reflects that
During the first 30 minutes, oxygen levels increase. From 30 minutes to 60 minutes, oxygen levels decrease.Since during photosynthesis there is a release of oxygen that occurs when water molecules break, we can expect an increase in the molecule concentration in the air surrounding the Rubric plant. We can assume that photosynthesis is happening during the first 30 minutes.
Since the respiration process consumes oxygen, we can expect a decrease in the molecule concentration in the air surrounding the Rubric plant. This process might take place from 30 to 60 minutes.
