XOR(B4=12;C4<9) and =AND(B4=12;C>9) return TRUE, if the value in cell B4 is 12 and the value in C4 is 29.
An =XOR function returns TRUE if any of the clauses in it are true, while an =AND function returns true only if both are true. Therefore, since in =XOR(B4=12;C4<9) B4 does equal 12, since this is an =XOR function. =AND(B4=12;C>9) is correct because B4 = 12 and C4 is greater than 9. if the value in cell b4 is 12 and the value in c4 is 29? and return true, if the value in cell b4 is 12 and the value in c4 is 29. XOR(B4=12;C4<9) and =AND(B4=12;C>9) return.

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.

Complete a dichotomous key for the 10 leaves on the Common Leaves sheet.
Answer:
1) leaf margin smooth
2) leaf margin toothed
3) leaf margin smooth
4) leaf-type needle-like
Explanation:
Use this phylogenetic tree and your knowledge of cladistics to determine the relationships between these species.
Rank the species from most closely related to horseflies to most distantly related to horseflies. If two species are equally close in their relatedness to horseflies, overlap them.
most closely related to horseflies
katydid
dragonfly
human body louse
silverfish
flea
mayfly
most distantly related to horseflies Background Image
The tree shows that at the first branch point, the lineage leading to horseflies split off from the lineage leading to dragonflies, mayflies, and silverfish. These three species are therefore most similar to horseflies.
Which of the following depicts the phylogenetic tree's root, which denotes the ancestral lineage from which all of the tree's species descended?A phylogenetic tree's root denotes the ancestral lineage from which all of the creatures on the tree descended. A branch point shows the split of two lineages. A basal taxon is an early-evolving lineage that has not branched. Sister taxa are those that originate from the same branch point as another lineage.
Which phylogenetic tree type out of the ones shown below relates to the single ancestral lineage?A clade is a segment of a phylogeny that consists of an ancestral lineage and all of that lineage's offspring. Due to the monophyly of this group of species, it is also possible to refer to it as

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.

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.

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.
