Are responsible for recycling matter back into the food web once an organism has died
Answer:
Decomposers.
Explanation:
Decomposers break down dead matter to recycle it back into the ecosystem. Have you ever seen mushrooms on a dead log? They're there because they are breaking down the dead matter, which gets recycled back into the Earth.

A student incorrectly measured the volume of a mineral sample as 83 cubic centimeters when
the actual volume was 89 cubic centimeters. What was the student's approximate percent
deviation (percentage of error)?
1.
6.7%
2.
7.2%
3.
9.3%
4.
14.8%
Answer:
1. 6.7%
hope it helps <3
The percentage deviation in the student's calculation is 6.74%.
We have a student who incorrectly measured the volume of a mineral sample.
We have to determine student's approximate percent deviation.
How to calculate the Percentage deviation ?In order to calculate percent deviation , subtract the true value from the measured value, then divide by the true value, then multiply by 100.
According to the question -
Measured volume (M) = 83 cubic centimeters.
Actual Volume (A) = 89 cubic centimeters.
ΔV or [tex]$\delta[/tex]V = M - A = 83 - 89 = - 6
Therefore -
|Percentage deviation| = [tex]\frac{\delta V}{A} \times 100[/tex] = - ( [tex]\frac{6}{89} \times 100[/tex]) = - 6.74 % = 6.74%
Hence, the percentage deviation in the student's calculation is 6.74%.

what orgamisim will develop pharyngeal arches
The first, most anterior pharyngeal arch gives rise to the oral jaw. The second arch becomes the hyoid and jaw support.

Define Hydrophilic. Which part of the membrane is
hydrophilic?
Answer:
Cell Membranes
Phospholipids are amphiphilic, meaning they are both attracted to water in one region of the molecule, and repel water in other regions. The head of the phospholipid molecule is the hydrophilic region. The tails are the hydrophobic region, and point inward, toward each other.
Explanation:
Answer:
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. As shown in the diagram below, each phospholipid molecule has a head and two tails. The head “loves” water (hydrophilic) and the tails “fear” water (hydrophobic).

how the cell membrane and chloroplast might work together to make food in a particular cell?
A In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast uses nutrients to make energy (ATP)
for the cell.
B. In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by
photosynthesis.
C. In animal cells, the cell membrane allows materials in and out of the cell, while the chloroplast uses nutrients to make energy (ATP)
for the cell.
Din animal cells, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by
photosynthesis.
Answer:
B. In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by
photosynthesis.
Explanation:
The choice that represents the best example of how the cell membrane and chloroplast might work together to make food in a particular cell is as follows:
In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by photosynthesis.Thus, the correct option for this question is B.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates the internal environment of the cell with respect to its outer one. It is semi-permeable in nature. It means that some molecules, ions, or compounds can easily diffuse across the lipid bilayer while others are not.
The movement of materials in and out of the cell is typically facilitated by the cell membrane. While in plants, the chloroplast is a membrane-bound cell organelle that has green pigments that captures light energy from sunlight and convert it into chemical energy in order to synthesize food (glucose) that provides them energy for metabolic activities.
Therefore, in a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by photosynthesis. Thus, the correct option for this question is B.

The orbital eccentricity (or eccentricity) is a measure of how much an elliptical orbit is 'squashed'. ... Elliptical orbits with increasing eccentricity from e=0 (a circle) to e=0.95. For a fixed value of the semi-major axis, as the eccentricity increases, both the semi-minor axis and perihelion distance decrease. or
It is probably used because the more eccentric an ellipse is, the more its foci are 'off the center' of the ellipse. ... These orbits turned out to be ellipses with the sun at one of the focus points. In this context, the eccentricity of the ellipse indicates how far from circular these orbits are.

What factors challenge the stability of an organism?i
Answer:
Abiotic factors.
Explanation:
Abiotic factors such as temperature and humidity etc challenge the stability of an organism by providing the harsh environment. This harsh environment disturbs the stability of the organism. Increase in temperature and very less or high humidity imbalance the enzyme activity which disturbs the whole functioning of the body of organism. So for chemical processes in the body, suitable temperature is required.

Which scenario would most likely result in the extinction of one or more species? The water temperature of a pond decreases slightly, and the members of the pond populations adapt to the change. The conditions are abnormally dry for one season in a desert, resulting in the deaths of a few members of a snake population. A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish. A new plant species begins growing in a forest, resulting in a new food resource for many animal populations.
Answer:
The scenario which would most likely result in the extinction of one or more species is A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.
Explanation:
Among the four given scenario, one of the scenario would most likely result in the extinction of one or more species that is "A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish." The rest three does not implies about the extinction of the species.
A pond's water temperature decreases significantly, and the members of the population of the pond adjust to the transition. In this argument, depending on climatic and seasonal shifts, and on how a pond is used, the composition of pond water changes continuously. Good management aims at managing the composition in order to create the best conditions for the fish. In this case, the pond population will then alter their adaptations rather than disappear or become extinct.The conditions in the desert are abnormally dry for one season, resulting in the deaths of a few members of a population of snakes. For only one season, which is temporary, the abnormal condition persists in this case, resulting in the deaths of only certain snakes. Hence, because the dry state is temporary, the extinction of the snakes does not occur. A predatory fish is introduced into a lake, resulting in a drastic decline in smaller fish populations. This argument is right about the extinction of species as the predator fish will eventually consume all the small fishes and the small fish will slowly and gradually disappear and become extinct day by day.In a forest, a new plant species starts developing, resulting in a new food supply for many populations of animals. In this case, there will be no loss or extinction of organisms when new species are introduced, and it will ultimately result in the creation of new food sources and species.Hence, the answer is - A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.

Accepted by coworkers is the correct option.
Explanation:
The young woman's refusal to "tell others" about the deal triggers a question about what would be accepted by coworkers because her actions will determine what others will think about the issue, their ideaologies and what actions they might take.
