Human muscle cells use lactic acid fermentation to produce more atp than is possible through complete aerobic respiration.
How does human muscles cells function?Human muscle cells use lactic acid fermentation to produce ATP without requiring oxygen (anaerobic metabolism). During intense exercise or when oxygen supply is limited, muscle cells produce ATP through the breakdown of glucose to pyruvate via glycolysis.
In the absence of oxygen, pyruvate is converted to lactate through lactic acid fermentation, which regenerates NAD+ that is required for glycolysis to continue. This allows the muscle cells to continue producing ATP even when oxygen supply is limited.
However, lactic acid fermentation produces less ATP than complete aerobic respiration, which is the process that utilizes the electron transport chain to produce ATP in the presence of oxygen.

How do you motivate yourself?Self-encouragement is the act of having faith in oneself and your capacity to overcome obstacles and handicaps. Focusing on your strengths, good traits, and abilities rather than your flaws and shortcomings is known as self-encouragement.
What occurs when someone is encouraged?It implies that while those receiving encouragement might not even be aware of it consciously, the effects of the process are evident in their behavior. People who are encouraged are more likely to act, take responsibility, exhibit initiative, voice their opinions, and feel more energised and driven overall.

Explanation:
A friend tells you that garbage can turn into maggots, which are fly larvae. What part of the cell theory could you use to disprove this claim?.
All live cells originate from pre-existing cells, in accordance with the Schwann and Schleiden cell theory. Garbage that is decomposing (organic waste) cannot produce maggots on its own.
Fly is required for the growth of maggots (whether it lay eggs or not). Fly eggs are laid in organic debris that is decomposing, such as in trash cans, dung, roadkill, etc. Although it seems repulsive, that is how nature works. These eggs develop into larvae, or more often known as maggots.
Maggots often only remain alive for five to six days before developing into pupae and then adult flies. The solitary eggs of the house fly resemble rice grains. House fly eggs develop into larvae, also called maggots, in just one day. White, legless insects known as maggots eat from the location where eggs are laid.

a species of tree has a flexible body structure that allows it to support heavy weights without snapping, and each of its needles is covered by a cuticle to prevent moisture loss. in which of the following biomes would this tree be most likely to thrive? desert taiga temperate grassland tropical rainforest
In the taiga biome, this tree is most likely to thrive. Therefore, option B is correct.
What is the taiga biome?The taiga, commonly referred to as the boreal forest, is the world's northernmost and coldest forest. It is made up primarily of the conifer species larch, birch, and aspen, as well as the evergreen spruce, fir, and pine.
Coniferous woods are those that have evergreen trees that produce cones. Elegant pines coexist in this environment alongside tamarack, spruce, and fir.
Thus, In the taiga biome, this tree is most likely to thrive. Therefore, option B is correct.

the equilibrium potential for a cation is 120 mv. which of the following statements is true when a cell is at the resting membrane potential (-70 mv)?
When the cell is at the resting membrane potential (-70 mv), both the chemical and electrical forces are channeled into the cell.
Define resting membrane potential
The electrical potential difference across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is traditionally used to describe the electrical potential difference across a cell membrane.
Any ion's equilibrium potential value is determined by the gradient of that ion's content across the membrane. The force of the concentration gradient and the equilibrium potential would both be zero if the concentrations on the two sides were identical.

Which of the following statements describes a major advantage of light microscopy over electron microscopy?
a. light microscopy provides higher magnification than electron microscopy
b. light microscopy provides visualization of the topography of cell surfaces
c. light microscopy allows the visualization of dynamic processes in living cells
d. light microscopy provides higher resolution than electron microscopy
The correct statement is:
c. light microscopy allows visualization of dynamic processes in living cells
What are the advantages of light microscopy over electron microscopy?Light microscopy has a major advantage over electron microscopy in that it allows for the visualization of dynamic processes in living cells. This is because light microscopy uses lower-energy photons to illuminate the sample, which is less likely to cause damage to living cells. In contrast, electron microscopy uses high-energy electrons, which can damage or kill living cells. While electron microscopy can provide higher magnification and resolution than light microscopy, it typically requires that the sample be fixed and stained, which precludes the observation of dynamic processes. Light microscopy is also better suited for visualizing the topography of cell surfaces, while electron microscopy is better suited for visualizing the internal structure of cells.
