Answer:
In series : 1/C=1/C1+1/C2
1/C=1/1+1/2
1/C=3/2
C=2/3=0.66
Explanation:
Energy=1/2CV^2
Energy=1/2*0.66(100)^2
Energy=1/2*0.66(10000)
Energy=1/2*6600
Energy=3300J
The energy stored in the system of capacitors is 3350 μF-Volt the energy stored in the system of capacitors is 3350 μF-Volt.
To find the total energy stored in the system of capacitors connected in series, we need to follow these steps:
Step 1: Calculate the equivalent capacitance (C_eq) for capacitors connected in series.
When capacitors are connected in series, the reciprocal of the equivalent capacitance (1/C_eq) is equal to the sum of the reciprocals of the individual capacitances (1/C1 + 1/C2).
For two capacitors, C1 = 1μF and C2 = 2μF, the equivalent capacitance (C_eq) is given by:
1/C_eq = 1/C1 + 1/C2
1/C_eq = 1/1μF + 1/2μF
1/C_eq = 2/2μF + 1/2μF
1/C_eq = 3/2μF
Now, find the equivalent capacitance (C_eq):
C_eq = 2/3 μF = 0.67 μF
Step 2: Calculate the total energy (E) stored in the system.
The energy (E) stored in a capacitor is given by the formula:
E = (1/2) * C * [tex]V^2[/tex]
Where:
E = Energy stored
C = Capacitance
V = Voltage across the capacitor
Using the equivalent capacitance (C_eq ≈ 0.67 μF) and the supply voltage (V = 100V):
E = (1/2) * C_eq * [tex]V^2[/tex]
E = (1/2) * 0.67μF * [tex](100V)^2[/tex]
E = (1/2) * 0.67 * 10000μF-Volt
E = 3350μF-Volt
So, the energy stored in the system of capacitors is 3350 μF-Volt.

For the following questions, please fill in the blank with the correct number of chromosomes (e.g. 4). Please do not spell out the number (e.g. four) or include any kind of punctuation (e.g. 4.). In an organism where the diploid number of chromosomes is 2N=16, how many chromosomes would you expect to find in cells that are in G2 of the cell cycle?
Answer:
Double number of chromosome.
Explanation:
There are 16 chromosomes in G2 phase of the cell cycle because in G2 phase, the replication of DNA occurs which doubles the number of chromosome. It is a gap phase present between replication of DNA and mitosis so it contains 16 number of chromosomes in the cell. After mitosis, the chromosomes number distributed equally among daughter cells.

Which of the following statements best describes the function of a cell membrane?
( WILL MARK BRAINLIEST ) Please help ASAP
A. The cell membrane has many functions, but its primary action is to regulate the movement of materials into and out of the cell
B. The cell membrane has numerous functions, but its primary role is to keep organelles contained within the cell
C. The cell membrane has many functions, but its primary action is to act as a barrier to keep foreign substances from moving into the cell
D. The cell membrane's primary function is to move waste out of the cell
The correct answer as to which best describes the function of a cell membrane would be that the cell membrane has many functions, but its primary action is to regulate the movement of materials into and out of the cell. The correct option would be A.
The cell membrane primarily delimits the cell and act as an interface between the inner content of the cell and its surrounding.
The cell membrane is selectively permeable. Thus, it regulates the movement of materials between the cell's matrix and the surrounding.
Other functions of the cell membrane include:
By regulating the movement of materials in and out of the cell, the cell membrane ensures that the optimal range of concentration of substances is maintained within the cell. In other words, it maintains homeostasis.By surrounding the cell, the plasma membrane becomes the first line of contact for anything that might want to harm the cell. Hence, it serves protective functions.By selectively allowing and influencing some materials to move out or inside the cell, the cell membrane plays an integral role in the transportation of materials.

the diagram shows the general structure of a lipid l, which consists of two main parts.
which part is circled?
a- alcohol group
b- fatty acid
c- carboxyl group
d- unsaturated lipid
Answer:
The correct answer is - carboxyl group.
Explanation:
Lipids are one of the major macromolecules that are made up of fatty acid and carboxyl groups as two main parts of the molecules. The most common type of lipid is formed with the glycerol associated with the fatty acid chain.
In the provided structure the circled part is the carboxyl group with the long fatty acid chain. However, glycerol belongs to the alcohol group.
Thus, the correct answer is - carboxyl group.

Mitochondria have highly folded inner membrane that increase the membranes surface area for atp production. What concept does this illustrate?
1) a cell ability to maintain homeostasis is critical for life
2) catalysts speed up chemIcal reactions in cells
3) all livIng things are composed of cells
4) a cells structure is related to its function
Mitochondria have a highly folded inner membrane that increases the surface area for ATP production. This explains that a cell's structure is related to its function. So the correct answer is option 4.
What is the role of mitochondria in a cell?In an eukaryotic cell, the mitochondria are present and produce ATP through the Krebs cycle, the electron transport chain, and other cellular processes. The inner membrane of mitochondria is folded, and this membrane consists of many complexes that are required for the electron transport chain.
Due to the transfer of electrons, a proton gradient is formed that allows the formation of ATP. More complexes (ATP synthase) can fit into the membrane as it folds, and ATP production increases. To produce more energy, the mitochondria are made this way. Apart from this, other organs such as the intestine have villi that are highly folded to increase the rate of absorption.
Hence, the shape of each cell is related to its function. Option 4 is true for the statement.

The structures in the lungs where gas exchange occurs are called ___________.
Answer:
Alveoli
Explanation:
Gas exchange refer to the transmission of oxygen from the lungs to the bloodstream and removal of carbondioxide from the bloodstream to the lungs.
Gas exchange occur in the alveoli of the lungs and the capillaries envelope in them. Alveoli is responsible for diffusion of gases to the blood stream through the lungs and removal of gases.
Inhaled oxygen is moved from the alveoli to the blood capillaries and carbondioxide is eliminated from the blood capillaries into the alveoli.

Characteristics of asthma include:___________.a. Chronic inflammatory disorderb. Airway hyperresponsivenessc. Alveolar collapsed. Genetic susceptibilitye. Airway remodeling
Answer:
The correct answer is a.
Explanation:
Asthma is characterized by a chronic inflammatory process of the airways in which a variety of cells predominate, such as eosinophils, neutrophils, and mast cells. Chronic inflammation produces an increase in airway reactivity and recurrent episodes of wheezing, respiratory distress, intercostal pulling, coughing, and chest tightness, especially at night and in the morning. Asthma is a disease in which there is bronchial hyperresponsiveness, which is an exaggerated response of the bronchial mucosa and leads to bronchospasm and bronchitis.
