The renewable energy source in all cells would be;
ATP (adenosine tri phosphate)
ATP is responsible for active transport, cellular respiration and many other cell activity. Cells would die without ATP and then so will the organism itself.
______ act like underwater windmills, except the rotors are
driven by moving water instead of air.
A. tidal fence
B. tidal turbine
C. tidal barrage
Answer: tidal turbine
Explanation:
Answer:
B
Explanation:
For most tidal energy generators, turbines are placed in tidal streams. A tidal stream is a fast-flowing body of water created by tides. A turbine is a machine that takes energy from a flow of fluid. That fluid can be air (wind) or liquid (water). Because water is much more dense than air, tidal energy is more powerful than wind energy. Unlike wind, tides are predictable and stable. Where tidal generators are used, they produce a steady, reliable stream of electricity.

:) How does reducing heart rate during a dive enable animals to stay underwater longer?
Reducing heart rate during a dive helps animals stay underwater longer by conserving oxygen and redirecting blood flow to vital organs.
Explanation:The reduction in heart rate during a dive enables animals to stay underwater longer as part of the diving reflex. This reflex diverts blood to essential organs while submerged. When the heart rate slows down, it conserves oxygen and directs more blood flow to critical organs, helping the animal to stay submerged for extended periods.
For example, in marine mammals like whales and seals, the diving reflex reduces heart rate and shunts blood preferentially to the brain and other vital organs, allowing them to conserve oxygen and stay underwater for extended periods.
By reducing heart rate, animals can stay underwater longer by minimizing oxygen consumption and redirecting blood flow to important organs.
Which of the interidal zones experiences the highest complexity and diversity of marine life?
Answer:
Lower littoral has the highest complexity and diversity of marine life.
Explanation:
Because the water is shallow enough and suitable for seaweeds to get enough sunlight. It's also protected from large fish because of the wave action and the relatively shallow water.
Final answer:
While the intertidal zone has a significant variety of marine life adapted to its harsh and dynamic conditions, the highest biodiversity in marine biomes is found in estuaries and coral reefs.
Explanation:
The intertidal zone, which is the area between high and low tide, exhibits a significant variety of marine life due to the challenging conditions organisms must face, such as exposure to air at low tide and submersion during high tide. Despite this complexity, the intertidal zone is not the marine biome with the highest biodiversity. This title is held by estuaries and coral reefs, which present the most complex and biodiverse environments in marine biomes. The organisms in the intertidal region have adaptations like tough exoskeletons to protect against desiccation and wave damage, but the dynamic nature of this zone limits the establishment of more static life forms like plants and algae.
Portions of an MRNA strand that do not code for proteins are
A. exons
B. introns
C. caps
D. tails
Answer: Introns
Explanation: Introns are non-coding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is translated into a protein.
The portions of an mRNA strand that do not code for proteins are:
B. introns.
- Introns are non-coding regions of mRNA that are transcribed from the DNA but are removed during mRNA processing.
- Unlike exons, which contain coding sequences for proteins, introns are spliced out to produce a mature mRNA molecule that consists only of exons.
- Introns are intervening sequences found within a gene that do not encode protein sequences.
- During mRNA processing, introns are removed through a process called splicing, leaving only the exons, which contain the protein-coding sequences.
- This splicing process ensures that the mature mRNA molecule contains only the necessary genetic information for protein synthesis.
- Introns play roles in gene regulation, alternative splicing, and evolution, and their presence allows for the generation of multiple protein isoforms from a single gene.
- Exons, on the other hand, contain the coding sequences that are translated into proteins.

Describe the role of the American alligator as a keystone species
Alligators have a big habit of helping carnivores like the wolf, cougar, bear, etc. hunt off deer and fish. Even with this amount of carnivores around, just a simple change as one carnivore removal such as the alligator would increase the fish population. This would make the bears have more time for fishing. The next thing to happen would lead to bears increasing more rapidly, then deer, elk, and moose begin to decrease due to the bear increase.
during which stage of the cell cycle does DNA replication occur?
Answer:
At mid-interphase
Explanation:
The DNA replicates during the S phase of interphase, after G1 and before G2, the two growth phases. Throughout interphase, the DNA is extended, and free nucleotides have access to the strands.
During division (M phase) the DNA is condensed, so that the chromosomes are short, compact, and easily moved to the poles of the spindle.
DNA replication takes place during the S phase or synthesis phase of the cell cycle, which is part of interphase. This precedes the mitotic phase where actual cell division occurs. This process ensures each daughter cell receives an identical copy of DNA.
Explanation:The process of DNA replication occurs during a specific phase of the cell cycle known as the S phase, or synthesis phase. During this stage, DNA replication can proceed, resulting in the formation of identical pairs of DNA molecules, or sister chromatids, that are essential for successful cell division. The S phase occurs as part of interphase, prior to the cell's entry into the mitotic phase where actual cell division takes place. The cell cycle is a series of carefully timed and regulated stages that involve cell growth, DNA replication, and cell division, leading to the formation of two new daughter cells, each with an identical copy of the DNA.

What do you mean by alleles?According to the leading textbooks on genetics and evolution, an allele is a variation of the same sequence of nucleotides at the same location on a long DNA molecule.
At a given genomic location, an allele is one of two or more versions of the DNA sequence (a single base or a segment of bases). For any given genomic location where there is variation, an individual inherits two alleles, one from each parent.
For instance, a prevailing allele can supersede the characteristics of other latent alleles, and these properties assist with concluding things like an individual's eye and hair tone.

If the outside temperature decreases by 20 degrees Celsius, what will happen to a reptile’s body temperature?
Final answer:
A reptile's body temperature will decrease with a 20-degree Celsius drop in outside temperature due to their ectothermic nature. They become sluggish and may enter estivation to conserve energy, performing only vital functions to survive.
Explanation:
If the outside temperature decreases by 20 degrees Celsius, a reptile's body temperature will also decrease. This is because reptiles are ectothermic organisms, meaning their internal body temperature is determined by their surrounding environment. Unlike endothermic animals, which can generate internal heat to maintain constant body temperature, reptiles must rely on behavioral adaptations to regulate their temperature. Reptiles, such as an American alligator basking in the sun, absorb heat when it is available to increase their body temperature.
When environmental temperatures drop, reptiles like snakes will seek shelter and become sluggish as their body temperature falls. This slowdown can affect their heart rate, breathing rate, and overall metabolic function. Some reptiles may enter a state of estivation, a period of inactivity and lowered metabolic rate, to conserve energy and survive until temperatures become favorable again. In essence, a reptile's body will perform only critical activities necessary to sustain its living state during such times.
Final answer:
A reptile's body temperature will likely decrease if the outside temperature drops by 20 degrees Celsius because reptiles are ectotherms and their temperature varies with environmental conditions. They may enter brumation to cope with the cold.
Explanation:
If the outside temperature decreases by 20 degrees Celsius, the body temperature of a reptile is likely to decrease as well since reptiles are ectotherms. Reptiles rely on external heat sources to regulate their body temperature. Without behavioral adaptations such as basking in the sun, a reptile’s body temperature will drop in response to the cooler environmental temperatures. This is because reptiles are also poikilotherms, meaning their body temperature varies with the environment.
In colder conditions, reptiles may enter a state of brumation, a dormancy-like state where metabolism slows down and the reptile becomes very sluggish. It is important for reptiles to find ways to maintain their body temperature, as a significant drop can affect their physiological processes and overall survival.

D) AGCT represent nitrogenous bases: Adenine, Guanine, Cytosine and Thymine respectively.
E) The structure of DNA is supported by a backbone called deoxyribose sugar
F) The complementary strand is TACGTC
Explanation: A nucleotide is consist of a nitrogenous base, a deoxyribose sugar and a phosphate group. The nitrogenous bases found in DNA are Adenine, Guanine, Cytosine and Thymine and are represented as A, G, C, and T respectively. The bases in one DNA strand from bonds with the bases in the complementary strand thus forming steps in the double stranded DNA. In bond formation among the bases, Adenine bonds with Thymine while Guanine bonds with Cytosine. Therefore in a double stranded DNA, wherever G is found in one strand, C occurs in the complementary strand and wherever A is found, T occurs in the complementary strand.

are Chromosomes structures are always present in a cell.
Answer:
No.
Explanation:
Chromosomes are visible only in reproduction otherwise they are in thread like structure called chromatin. Almost all nucleated cells contain chromatin or chromosomes while non-nucleated cells don't have chromosomes because chromosomes are always present in nucleus. Non-Nucleated cells include Red Blood Cells and thrombocytes.
Final answer:
No. Chromosomes are only coiled and visible during cell division; otherwise, they exist as chromatin, an uncoiled DNA-protein complex, within the nucleus.
Explanation:
Chromosomes are structures found within the nucleus of a cell and are comprised of DNA, the hereditary material, and proteins. These structures are not always present in their familiar condensed form; they are visible and distinguishable from one another only during cell division when the DNA coils into thick structures. In eukaryotes like humans, chromosomes are linear, and each species has a specific number of chromosomes.For instance, human cells contain 46 chromosomes. At other times, during phases like growth and maintenance, this DNA-protein complex exists as chromatin, which resembles unwound strands rather than distinct chromosomes.The coiled structure of chromosomes during cell division ensures the proper segregation of genetic material to daughter cells. Chromatin is the less condensed form of DNA that serves as a material from which chromosomes form.In summary, while chromosomes in their characteristic coiled form occur only during cell division, chromatin is always present within the nucleus, representing the uncoiled state of the chromosome's DNA-protein complex.Put the steps of dna replication in order:

Which species will most likely have the most genetic diversity among their offspring
Answer:
Species that reproduce sexually have greater genetic diversity than species that reproduce asexually.
Explanation:
Species that reproduce sexually and have a wide variety of forms within their genus are most likely to exhibit the highest genetic diversity among their offspring, proving crucial for adaptation and evolution.
Among different species, those with a higher variety of forms and ecological roles are likely to have the most genetic diversity among their offspring.
This diversity is crucial for adaptation and the potential for evolution, emphasizing the importance of sexual reproduction in contributing to genetic variability.
Species that undergo sexual reproduction, where the genetic material of two individuals combines, tend to produce offspring with significant genetic differences from their parents.
This variability is a key asset in adapting to changing environments and overcoming challenges.
Therefore, among various species, those that reproduce sexually and have a wide range of types within a genus will likely exhibit the highest genetic diversity among their offspring.
