Answer:
There are several ways in which animals losses energy such as movement from place to place, muscle movement and respiration etc.
Explanation:
When animals such as deer, cow, rabbit etc feed on plants. Only 10 percent of energy is transferred from plants to the animal and the remaining is lost as heat energy in the atmosphere. This 10 percent of energy is used by the animals in muscle building and performing other activities such as movement and respiration. In respiration process, food molecules are broken down to produce energy and this energy is used in different processes.
Final answer:
The energy that animals obtain from plants is mostly lost as heat due to metabolic processes, with only about 10% retained in the animal's body tissue.
Explanation:
One way that an animal loses some of the energy it gets from a plant is through heat release during its metabolic processes. When an herbivore eats a plant, it uses the energy to maintain its bodily functions, such as movement, growth, and reproduction. During these activities, most of the energy is used and converted into heat, which is then lost to the environment. This is a demonstration of the second law of thermodynamics, which states that energy transfer leads to a loss of energy through heat. Only about 10% of the energy is retained and transformed into body tissue, while the rest is expended.
Carbon is a major component of all organic compounds, including carbohydrates, lipids, proteins, and nucleic acids. Carbon dioxide is continually exchanged between the atmosphere and oceans. What geological process returns carbon to the atmosphere in the form of carbon dioxide?
A) respiration
B) transpiration
C) volcanic activity
D) decomposition of marine sediments
Final answer:
Volcanic activity is the geological process that returns carbon to the atmosphere as carbon dioxide, playing a crucial role in the carbon cycle by releasing carbon stored within the Earth's mantle.
Explanation:
The geological process that returns carbon to the atmosphere in the form of carbon dioxide is volcanic activity. This activity brings carbon stored deep within the Earth's mantle back into the carbon cycle. Volcanic eruptions release carbon dioxide into the atmosphere that was locked in the mantle or in long-term carbon reservoirs such as carbonates and fossilized organic materials.
Other processes involving carbon include photosynthesis, where carbon dioxide is converted to organic carbon by plants and algae, and respiration, where living organisms release carbon dioxide back into the atmosphere. Additionally, carbon is cycled slowly through other geological processes such as the formation and decomposition of limestone, and through human activities like the burning of fossil fuels.
Final answer:
Volcanic activity is the geological process that returns carbon to the atmosphere as carbon dioxide, playing a critical role in the Earth's carbon cycle.
Explanation:
The geological process that returns carbon to the atmosphere in the form of carbon dioxide is volcanic activity. Volcanoes release carbon dioxide gas that has been stored within the Earth's mantle. This process is a part of the carbon cycle, which includes the exchange of carbon among the atmosphere, oceans, and living organisms on Earth. Long-term storage of carbon also occurs when organic matter from living organisms becomes fossilized deep underground, and volcanic activity plays a key role in returning this carbon back to the carbon cycle through eruptions that release stored carbon dioxide into the atmosphere.
Which statement BEST describes a similarity and a difference between photosynthesis and cellular
respiration?
A. Photosynthesis and cellular respiration both use carbon dioxide to create energy, but while animal cells
respire it as a waste product, plant cells absorb it for their use.
B. Photosynthesis and cellular respiration both produce glucose molecules, but while cellular respiration
requires the ingestion of glucose in animal cells, plant cells are able to create their own during
photosynthesis.
C. Photosynthesis and cellular respiration both occur in the chloroplasts, but while photosynthesis only occurs
in plant cells, cellular respiration occurs in both plant and animal cells.
D. Photosynthesis and cellular respiration both produce energy, but while photosynthesis assembles glucose
molecules in plant cells, cellular respiration breaks down glucose molecules in plant and animal cells.
Answer:
d
Explanation:
photosynthesis creates the end product of glucose used for energy while cellular respiration breaks down glucose in order to make its own energy
Answer:
Option D. Photosynthesis and cellular respiration both produce energy, but while photosynthesis assembles glucose molecules in plant cells, cellular respiration breaks down glucose molecules in plant and animal cells.
Explanation:
Cellular Respiration: A catabolic reaction that occurs in the Mitochondria of all living organisms which involves breaking down glucose or sugar molecules using oxygen to release energy and carbon dioxide.Photosynthesis: An anabolic reaction that occurs in the chloroplast of phototrophic plants involves the production of glucose in the presence of carbon dioxide to release oxygen.The similarity between the two processes is that it involves the usage and production of energy and the exchange of gases.The difference between the two processes is that while cellular respiration breaks down glucose to use in other biological activities, photosynthesis produces glucose as food for the plants.For more information:

How does an enveloped virus gain/obtain/get its envelope?
The envelope is produced by the organelles in the host cell.
The envelope is produced by the DNA/RNA of the host cell.
The virus builds its envelope after it has been released from the host cell.
The envelope come from the host cell membrane as the virus leaves the host cell
Answer:
The envelope come from the host cell membrane as the virus leaves the host cell
Explanation:
A virus is an organism that is incapable of replicating on its own without infecting a living host. A virus consists of a genetic material (DNA or RNA) , a protein coat called CAPSID, and sometimes some viruses possess an envelope, which is an outer covering or enclosure. Viruses that possess this envelope are referred to as ENVELOPED VIRUS.
The virus lacks the ability to produce any structure, hence, they gain this envelope made of phospholipid from the cell membrane of the host they infect. During the infection cycle of a virus, a process called budding enables a portion of the host's plasma membrane to cover or encapsulate the virion cells, hence, making them enveloped in the process.

When scientists look at the bones of a dinosaur, why
do you think they decided the outside of a dinosaur
looks like a lizard rather than a furry animal or a
feathered animal?
Scientists first thought dinosaurs resembled lizards due to their reptilian features and close relation to reptiles like crocodiles. The discovery of feathered dinosaurs like Archaeopteryx has since provided evidence for their bird-like characteristics, although not all dinosaurs were warm-blooded or feathered.
When scientists look at the bones of a dinosaur, they initially surmised that dinosaurs had scaly, lizard-like skin rather than being furry or feathered based on their closest living relatives, such as crocodiles, and overall reptilian morphology. However, recent discoveries have challenged this notion, uncovering the existence of feathered dinosaurs. Archaeopteryx, an ancient fossil, displays characteristics of both dinosaurs and birds, suggesting a transitional form. It possesses both teeth, like dinosaurs, and feathers modified for flight, which are typically associated with birds. These feathery dinosaurs might not necessarily have been warm-blooded like modern birds, as not all dinosaurs had feathers, suggesting a diversity in their thermoregulatory strategies.
Moreover, birds are descendants of a specific group of dinosaurs known as theropods, sharing several anatomical features, such as a furcula and specific bone structures in their hips and wrists, further supporting the feathered dinosaur hypothesis. Despite this feathered evidence, not all dinosaurs were endothermic, and the depictions of dinosaurs as lizard-like may have originated from the fact that some dinosaurs indeed had scaly skin, and this representation became culturally embedded before the discovery of feathered dinosaur fossils.

What is the result of eutrophication?
Eutrophication is the enrichment of the water bodies with excessive nutrients. As a result of eutrophication, algae deplete the oxygen causing the fish to die. Thus, option A is correct.
What is eutrophication?Eutrophication causes an excess increase in nutrients and minerals like nitrogen and phosphorus in the water body. It in turn increases the algal growth.
The algal bloom in the water causes a decrease in the biological oxygen demand (BOD) of the water resulting in the death of the fish. The lack of oxygen in the water leads to fish death.
Therefore, eutrophication causes fish death by the algal bloom.

Are viruses always fatal?
Answer:
No
Explanation:
The short answer is no, but the more complex one is that it depends on the virus. In the case of *****-19, the answer is no, as many people have recovered from it. But almost any viral infection can lead to sepsis, which is a chain reaction that can trigger inflammation throughout the body and damage multiple organs. This, however, is very rare, though potentially fatal.
Answer:
Not all viruses are fatal.
Explanation: This pandemic is a virus thing that is going around and not all people are dying. There is some people who have the virus and got "rid of it". Not all viruses is fatal because viruses can include not only bacteria, but it can spread through saliva, air, blood.I hope this helps.
What term best describes a bee's role of gathering pollen? *
niche
predator
Parasite
Habitat
The term that best describes a bee's role in gathering pollen is 'pollinator,' reflecting its mutualistic relationship with flowering plants and its vital role in the ecosystem including food production.
Explanation:The term that best describes a bee's role of gathering pollen is pollinator. When bees collect nectar from flowers, pollen sticks to their bodies and is then transferred to other flowers, facilitating the process of pollination. This interaction between bees and flowering plants is known as a mutualistic relationship as per option 'd' because it is beneficial to both the bees and the plants. Bees obtain nectar, which they use for food, and plants receive assistance with their reproductive process through the transfer of pollen. As indicated in the options provided, this is not an example of a bee being a predator, a parasite, nor does it describe its habitat, but rather defines its ecological niche and the crucial role it plays in the ecosystem.
Honeybees are vital for numerous ecosystems and directly impact food production, through the pollination of an estimated 130 different varieties of crops in the United States, including fruits, nuts, and vegetables. The service provided by pollinators like honeybees is instrumental for our own food supply and has significant economic value.

Explain how ligand A and ligand B can cause identical cellular responses in a cell?
Ligand in cell signaling is defined as the molecules, which bind to specific receptors. Two ligands, for instance, ligand A and ligand B can generate a similar cellular response by binding to different receptors.
The ligands interact with the specific molecule in the target cell. If two same ligands are attached to the two different receptors, then they will generate two different responses.
Acetylcholine is such an example of a ligand, which when attached to two different receptors will generate the same response.
This type of response can also be generated in epinephrine and glucagon. These ligands are responsible for controlling the transcription process in the DNA molecule.
Therefore, the ligands are the molecules that bind to the receptor and generate a signal.
To know more about ligands and cell signaling, refer to the following link:
https://brainly.com/question/21626532
Ligand A and ligand B can cause identical cellular responses by binding to the same receptor or different receptors that activate the same signal transduction pathway using common second messengers and similar downstream components.
Explanation:The phenomenon where ligand A and ligand B cause identical cellular responses can be explained through the concept of signal transduction pathways. These pathways start with the binding of a ligand to its specific receptor, initiating a cascade of biochemical events inside the cell. It is possible for different ligands to bind to the same type of receptor (or different receptors that trigger the same pathway) and produce the same response due to the use of common second messengers and similar downstream signaling components within the cell.
One scenario is that different cell types produce the same receptor, which binds to the same ligands, but triggers different responses in each cell type. Alternatively, cells may contain different genes that produce different receptors capable of binding to the same ligand, leading to diverse responses. Moreover, the interaction between ligands and G-protein-linked receptors, ligand-gated ion channels, and receptor tyrosine kinases can activate varied intracellular reactions even though the same second messengers are involved.
In the context of autocrine signaling, a cell may send and receive the same signal, which can regulate processes such as pain sensation, inflammation, and programmed cell death. Whether the signal impacts only the signaling cell or also affects neighboring cells can determine the overall biological outcome. Such specificity in signaling allows for precise control over cellular function and differentiation during organism development.
