Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

for lytic viruses, is a phase during a viral growth curve when the virus is not detected.
For lytic viruses, there is typically a latent period during the viral growth curve when the virus is not detected.
During this phase, the virus has entered the host cell and has begun to replicate its genetic material, but no mature virions have been produced yet. The duration of the latent period can vary depending on the virus and the host cell, and it can range from a few hours to several days.
After the latent period, the lytic viruses enters a rapid growth phase, during which the number of virions produced increases rapidly. This phase is characterized by a steep increase in the viral titer, which can be measured using various methods such as plaque assays or quantitative PCR. The rapid growth phase is followed by a plateau phase, during which the number of virions produced levels off and reaches a maximum.
Finally, the viral growth curve enters a decline phase, during which the number of virions decreases as the host cells are destroyed and the infection is cleared. The duration of the decline phase can vary depending on the immune response of the host and the effectiveness of antiviral treatments, if any.

Does anyone knows than answer ? Help me !
Out of the organisms listed, the one that is likely to have 10% of the energy passed on is the buzzard. Therefore, option (A) is correct.
What is second law of thermodynamics?In an ecosystem, only about 10% of the energy available at one trophic level is passed on to the next trophic level. This is due to the second law of thermodynamics, which states that energy is lost as it moves through a system.
Out of the organisms listed, the one that is likely to have 10% of the energy passed on is the buzzard (option A). Buzzards are predators that feed on a variety of small animals, including mice, foxes, and ladybirds.

How does adenosine triphosphate (ATP) become adenosine diphosphate (ADP)?
ATP stores energy as a phosphate bond is formed.
ATP releases energy as a phosphate bond is formed.
ATP releases energy as a phosphate bond is broken.
ATP stores energy as a phosphate bond is broken.
The correct answer is ATP releases energy as a phosphate bond is broken.
ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate) when a phosphate group is removed from ATP, resulting in the release of energy. This process is known as hydrolysis, where water molecules are used to break the bond between the terminal phosphate group and the rest of the molecule.
During cellular metabolism, ATP serves as the primary energy currency of the cell. When energy is required for various cellular processes, the phosphate bond in ATP is broken by an enzyme called ATPase. This enzymatic hydrolysis reaction cleaves off one of the phosphate groups, resulting in the formation of ADP and an inorganic phosphate molecule (Pi). The released phosphate group is then available to be used in other cellular reactions.
The conversion of ATP to ADP is an essential part of energy metabolism in cells. The energy released during this process is utilized to drive various cellular activities, such as muscle contraction, active transport of molecules across cell membranes, and synthesis of macromolecules. Once ATP is converted to ADP, it can be further hydrolyzed to AMP (adenosine monophosphate) if more energy is needed. Ultimately, the energy stored in ATP is released when the phosphate bond is broken, allowing cells to perform their vital functions.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

What was the climate like prior to the extinction ?
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.
I need help with this practice problem solving *I’m thinking maybe D.)
This new extinction has a component that has been widely controversial, meanwhile, some argue that is caused by human activities others argue that is due to cyclic changes on earth, the truth is that there are elements supporting both so it is highly likely that both causes are contributing, how in what measure we cannot know at the moment.

use this cross section to describe how mount rainier formed
Mount Rainier is a massive stratovolcano located in the Cascade Range in the state of Washington. It is composed of many layers of hardened lava, ash, and rock that erupted from a central vent. Over time, the layers accumulated and compressed under their own weight and the pressure of the surrounding rocks. This process of mountain building, called orogeny, caused the rocks to deform, break and uplift the land to form Mount Rainier. Type of terrain and climate also played a part in its formation. Glaciers and rivers eroded the surrounding land, and elevated the mountaintop by carving deep valleys, creating cirques and arêtes, and reshaping the landscape. Rainier was further enlarged by the eruption of melted glacial ice, ash flows, and lava flows from several small, overlapping volcanoes.
A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.
