Answer: Phytoplankton and the single-celled variety that krill eat are responsible for absorbing a massive amount of carbon from the atmosphere. In the absence of whales, krill would likely eat much of the free-floating phytoplankton on the ocean's surface, resulting in a marked acceleration in climate change.

Explanation:

Humans selectively fish out the largest species from Earth's oceans, causing their populations to dwindle. If that weren't alarming enough, the extinction of those animals—think a great white shark, bluefin tuna, and blue whale—could ripple down the food chain and spell extinction for entire ecosystems.

Answer:

algae population.

Explanation:

this would affect other aquatic life because algae absorbes oxygen and may cause fish to die of lack of food and oxygen

RbCl will give a yellow color in the flame test.

In a flame test, a small amount of a compound is placed on a platinum wire and heated in a flame. The electrons in the compound become excited by the heat and emit light, which is seen as a color.

Different elements produce different colors in the flame test. RbCl or Rubidium Chloride when heated in a flame, it produces yellow color due to the excitation of electrons from ground state to the excited state.

The color is specific to the element and can be used to identify the element in a sample. It's a qualitative analytical technique used for identifying specific metal ions in a sample. This method is also commonly used in laboratories for the analysis of minerals and salts.

Upon peptide bond formation, the tRNA linked to the polypeptide shifts from the P site to the A site is not true of the translocation step of translation elongation in bacteria.

MRNA and tRNAs are translocated dynamically through the ribosome during protein synthesis. Along with the movement of their associated codons in the mRNA, tRNAs migrate sequentially from the A (aminoacyl) site to the P (peptidyl) site to the E (exit) site.

The ribosome continues to translate each codon in turn throughout the elongation phase. A bond known as a peptide bond is used to connect each relevant amino acid to the expanding chain. Up until all of the codons are read, elongation continues.

Social exchange the following is not a way in which evolutionary theory explains pro-social behavior.

With this in mind, prosocial behavior can be viewed as requiring three elements: (1) the capacity to adopt another person's viewpoint and recognize that they are experiencing a problem; (2) the capacity to ascertain the cause of that problem; and (3) the motivation to assist them in resolving the issue.

Prosocial actions are those taken with the intention of assisting others. Concern for other people's rights, feelings, and welfare underpins these behaviors. Empathy and compassion for others are two behaviors that might be categorized as prosocial.

A. Products of the coupled reaction have lower free energy than products of the uncoupled reaction is correct statement concerning the energetic coupling of reactions.

Energetic coupling is a mechanism that involves the transfer of energy from an exergonic reaction to an endergonic reaction, allowing the latter to proceed. The exergonic reaction (in this case the phosphorylation of substrate B) releases energy, which is used to drive the endergonic reaction (in this case the AB synthesis from A + BP). As a result, the products of the coupled reaction have lower free energy than the products of the uncoupled reaction. This is because the energy released from the exergonic reaction is used to drive the endergonic reaction, thus decreasing the overall energy required for the coupled reaction to occur.

Explanation:

If ouabain was used to block Na+–K+-ATPase pumps, the cell would maintain a steady state with different membrane potential. Here option B is the correct answer.

Ouabain is a drug that blocks the activity of the Na+–K+-ATPase pumps, which are responsible for pumping potassium ions (K+) into the cell and sodium ions (Na+) out of the cell.

By blocking these pumps, ouabain prevents the maintenance of the normal concentration gradient of K+ and Na+ across the cell membrane, and as a result, it alters the membrane potential. The membrane potential would not become more negative and the Na+ would not go to equilibrium across the cell membrane.

During the transcription of a given portion of a dna molecule mRNA is synthesized on only one of the chains.

When both strands are transcribed, they make different copies of mRNA that can code for different proteins, and since a single molecule of DNA cannot make different proteins, only one strand of DNA is used during transcription. only. Instructions stored in DNA are read and processed by the cell in two steps: transcription and translation.

Each of these phases is a distinct biological process that involves several molecules. During transcription, a portion of the cell's DNA serves as a template for the formation of RNA molecules.

mRNA is produced during transcription. In the transcription process, single-stranded DNA is deciphered by RNA polymerase to synthesize mRNA. Physically, mRNA is a chain of nucleotides known as ribonucleic acid and is single-stranded.

Messenger RNA is translated simultaneously by multiple ribosomes in both prokaryotic and eukaryotic cells. As the ribosome moves away from the initiation site, another ribosome can bind to the mRNA and initiate synthesis of a new polypeptide chain.

Life at the bottom of a body of water, also known as the benthic zone, is vastly different from life at the top of a body of water.

The benthic zone is the region of the ocean or other body of water that is in contact with the bottom.

One of the main differences is the amount of light available. In the benthic zone, there is very little light, as most of it is blocked by the water above. This means that the organisms living in this zone have adapted to live in low light conditions, and many of them are bioluminescent.

Another difference is the pressure. At the bottom of the ocean, the water pressure is much higher than at the surface, and organisms living in this zone have adapted to withstand this pressure. Some have thicker cell walls or other structural adaptations to deal with the increased pressure.

The benthic zone also has different types of habitats and environments, such as rocky shores, sandy bottoms, or coral reefs, each with its own unique set of organisms that have adapted to that specific habitat.

There are fewer mistakes or mutation hazards if the DNA template used for repair is the same as the original, undamaged DNA sequence.

When chromosomal DSBs arise, the cell uses two sorts of repair pathways:

non-homologous end joining (NHEJ) and homology-directed repair (HDR). Fundamentally,

NHEJ-break ends can be ligated without a template but HDR-breaks require one to direct healing.

Both of these repair processes are frequently active in cells, albeit the HDR pathway often works poorer than the NHEJ pathway in the absence of a homologous template.

Hlnts stop codon particular nucleotide sequence in DNA, which tells the RNA polymerase to stop specific nucleotide sequence in mRNA to cease transcription, acts as a terminator in eukaryotic cells' mRNA synthesis.

Polymerase I transcribes ribosomal RNA, Polymerase II transcribes mRNA and miRNAs, and Polymerase III transcribes tRNA and other short RNAs in eukaryotes. Eukaryotes have three RNA polymerases, known as Polymerases I, II, and III. Although eukaryotic termination has not received as much attention as prokaryotic termination, the fundamental mechanisms are understood, and it has been noted that many eukaryotic RNA polymerase termination patterns exist. For instance, Polymerase III, like Rho-independent termination in prokaryotes, depends on a certain sequence and RNA secondary structure to cause transcript cleavage. Contrary to Polymerases I and II, which also call for the binding of termination factors, this is different.

Although both are termination factor dependent, Polymerases I and II employ different mechanisms to terminate transcription. Polymerase I uses a process similar to the prokaryotic Rho-dependent mechanism, whereas Polymerase II termination is more complex and involves two RNA polymerase-associated proteins, CPSF and CstF, which are responsible for recruiting the cleavage and polyadenylation enzymes, in a process that seems to couple termination with polyadenlyation.
