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. In fish, the other posterior arches contribute to the branchial skeleton, which support the gills; in tetrapods the anterior arches develop into components of the ear, tonsils, and thymus.
explain ecosystem deficiency
Answer:
An ecological deficit occurs when the footprint of a population exceeds the biocapacity of the area available to that population. If there is a regional or national ecological deficit, it means that the region is importing biocapacity through trade or liquidating regional ecological assets.

2. Use evidence from the diagrams of macromolecules and information provided earlier to revise your explanation about whether sugar molecules provide all the elements needed to make the four types of macromolecules.
Answer:
No - they do not contain nitrogen which is needed to make proteins and nucleic acids (sometimes lipids)
Explanation:
The four types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Sugars are carbohydrates, and contain carbon, hydrogen, and oxygen.
Lipids contain carbon, hydrogen, and oxygen, and sometimes other elements like nitrogen and phodphorus.
Proteins contain carbon, hydrogen, oxygen and nitrogen.
Nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and phosphorous

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.

Which organelles must be present within a cell of a geranium
leaf for respiration and
photosynthesis to occur?
A) cell wall and vacuole
B) ribosome and nucleus
C) mitochondria and chloroplast
D) endoplasmic reticulum and cell membrane
Mitochondria and Chloroplast organelles must be present within a cell of a geranium leaf for respiration and photosynthesis to occur. So, the correct answer is (C).
What is Mitochondria?
A mitochondria is an organelle found in the cell of most eukaryotes such as animals plants and fungi and is a double membrane structure that uses aerobic respiration to generate ATP which is used as a source of chemical energy. Mitochondria are also known as the powerhouse of the cell.
The main role of mitochondria is oxidative phosphorylation in which it generates ATP by using the energy that is released during the oxidation of the food we eat. It uses ATP, the primary energy resource for most chemical, biochemical and physiological processes.
It is used in the process of photosynthesis and respiration along with chloroplast in the plants. it is also known as Chondriosome or sarcosome.
Thus, Mitochondria and Chloroplast organelles must be present within a cell of a geranium leaf for respiration and photosynthesis to occur. So, the correct answer is (C).

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

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.

Answer:
What would be accepted by coworkers.
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.
If her refusal to tell others about the deal does not in one way or the other affect other Co workers negatively, the coworkers might accept it in a negative way and if it's affect them positively,they might accept it positively. The co-workers acceptance about the whole issues will be what they feel and their decision is and this can trigger actions.

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%.
