A scoop of ice cream is placed on top of a warm piece of pie in a bowl.

Answer:

b. The overall amount of energy in the bowl will neither increase nor decrease.

c. The ice cream will increase in energy.

Explanation:

b. The total amount of energy in the container will not increase or decrease. Since the energy is transferred from one element to another, the energy that dissipates is negligible.

In this case the energy of the pie is transferred to the ice cream, melting it.

c. The ice cream will increase in energy. As the heat is transferred from the pie to the ice cream. the movement between the particles of the ice cream increases, increasing its kinetic energy

Answer:

The overall amount of energy in the bowl will neither increase nor decrease.

Explanation:

The law of conservation of energy states that energy cannot be created or destroyed.

According to the cell theory, which describes cells?
aivan3 [116]
<span>The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. hope this helps but you should be more specific in the future</span>

As you may have found, population-based patterns can be found in the genotypes of particular genes. We did this exercise on a ha
Nikolay [14]
In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.

Using the sliding flament theory, explain (or draw) the process of sarcomere shortening. Start from the point where calcium woul
Arte-miy333 [17]

Answer:

  1. Calcium binds to troponin C
  2. Troponin T moves tropomyosin and unblocks the binding sites
  3. Myosin heads join to the actin forming cross-bridges
  4. ATP turns into ADP and inorganic phosphate and releases energy
  5. The energy is used to impulse myofilaments slide producing a power stroke
  6. ADP is released and a new ATP joins the myosin heads and breaks the bindings to the actin filament
  7. ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, starting a new cycle
  8. Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Explanation:  

In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing <u>calcium into the sarcolemma.</u> At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join to the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament.  Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

What environment would be least likely to grow bacteria and why? Here are your choices:
storchak [24]

Answer:

3.

Explanation:

A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface. The armpit of a human and a warm freshwater mud puddle are a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them
