"during photosynthesis plants absorb CO₂"
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
during the transcription of a given portion of a dna molecule _____.
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.

If a bear lived off just plants and berries, how much would they need to survive
Answer:
2-2.25 pounds at 140 calories/ounce on average.
5-6 pounds at 140 calories/ounce during the fall before hibernation.
Explanation:
How many calories do bears eat?On average, Bears eat around 5,000 calories a day. However, Bears eat around 20,000 calories a day during the fall season in preparation for hibernation. If a bear were to eat a solely plant-based diet, it would need to eat plants and berries that are high in calories per ounce to satisfy these metrics. Keep in mind that the climate and agriculture of where this bear is located may decrease its access to highly caloric plants. Therefore, the bear may need to compensate with more plant volume in its diet to ensure that its daily caloric metric can be accommodated.Please let me know if this helped!!!
Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren’t native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island’s squirrel population?
The three effects that these events will have on the island’s squirrel population include the red and black squirrels will have to compete for nutrition, the food availability for red squirrels may decrease, and the food availability for gray squirrels will not be affected.
What does competition for food availability in natural populations mean?Competition for food availability in natural populations can mean the difference between life and death. The struggle to survive can lead to the evolution of new and improved survival strategies, such as aggression and cooperation.
Therefore, with this data, we can see that competition for food leads to natural selection.

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 negative consequence of introducing the non-native earthworms to forests in the Great Lake regions?
PLease hurry
The earthworms reduce the resources available to other animals that eat dead plant matter.
The earthworm decreases the energy flow from one tropic level to the next.
The earthworms provide an additional food source for primary consumers.
The earthworms burrow, which reduces the nutrients, flow of air, and water underground.
Answer:
The earthworms reduce the resources available to other animals that eat dead plant matter.
Explanation:
The introduction of non-native earthworms in the Great Lakes region can have negative consequences on the ecosystem, including reducing the leaf litter and other organic matter in the soil, which is a main food resource for many species of animals and invertebrates, causing a decline in the population of those species.

Which of the following hypotheses is possible if the African plate continues to push toward
the Eurasian plate?
A. The Mediterranean Sea will increase in depth.
B. The Alps will not be affected.
C. Italy will become less mountainous.
D. A volcano will definitely erupt in Italy.
E. The Mediterranean Sea will decrease in size.
Answer:
A. The Mediterranean Sea will increase in depth.
As the African plate continues to push toward the Eurasian plate, the Mediterranean Sea is likely to increase in depth. This is because the African plate is pushing against the Eurasian plate, which is causing the Mediterranean Sea to become more deep over time. This process is known as "subduction" where the African plate is sinking beneath the Eurasian plate. As a result, the Mediterranean basin is becoming more and more deeper, and the other options B, C, D and E are not possible.

unlike life at the top of a body of water ,life at the bottom of the body of water
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.
What is Benthic zone?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.

Answer:
The sand can be considered as both destructive and constructive depending on the context.
Constructively, sand can be used to create landforms such as beaches and dunes through natural processes such as erosion and sedimentation. Sand can also be used in construction, for example as an ingredient in concrete or as a medium for sandblasting.
Destructively, sand can cause erosion and damage to coastal structures and infrastructure. Sand can also cause problems for vehicles and aircraft by creating dust storms and reducing visibility.
It's worth noting that the destructive effects of sand can be mitigated by proper management and planning, such as constructing barriers to protect against coastal erosion or taking measures to control dust storms.

B. Substrate A has higher free energy in the coupled versus the uncoupled reaction.
C. The activated substrate BP has higher free energy than substrate B.
D. AB synthesis from A + BP is exergonic because phosphorylation of substrate B is exergonic.
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.
