1)The picture is an aerial view of what and what type boundary forms this feature?
2 Make two observations about the picture
Answer:
The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.
Explanation:
The picture is given in the question is an aerial view of the fault line of San Andreas.
A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.
Observation:
A complex zone of crushed and broken rockMany smaller faults branchTwo capacitors of 1μF and 2μF are connected in series across a 100V supply. The energy stored in the system is ?
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.

In science, the testable and experimented information is accepted. Scientific Laws and theories are explanations accepted by scientists. Thus, options d and e are correct.
What are scientific laws and theories?Scientific laws are considered true and are said to be the principle that arrives from facts and is derived from experimental observations. They are statements that are used to predict the phenomenon of natural sciences.
They are formulated mathematically from the known knowledge and events of the occurrences. It is an important part of science that explains the relationships and interdependencies of the various factors and parameters. For example, conservation of mass is the law.
Theories, on the other hand, are structured explanation that uses scientific laws and hypothesis to test the reliability of the experiment and its conclusions. It uses the scientific method to test and verify whether the result is true or false. The kinetic theory of matter is a theory.

The liver is an example of organ of the digestive system. Which of the following statements describes the general function of this type of digestive organ? Secretes enzymes and other liquids that aid in the digestion and processing of food Physically interacts with the ingested food, for example, storing the food, moving the food along the digestive tract, or absorbing nutrients released from processed food
Answer:
Secretes enzymes and other liquids that aid in the digestion and processing of food
Explanation:
The liver is a large organ in the body, if not the largest. It possess a red-purple color and constitutes a part of the digestive system. The liver carry out many functions in the human body; inclusive of digestive function. Although it is not a main digestive organ.
During digestion, the liver is responsible for processing of absorbed nutrients by releasing certain hormones and chemicals like bile, which aids in digestion of fat. This is the reason the liver is considered a "gland"

Solution A and solution B are separated by a selectively permeable membrane. Solution A is hypertonic with respect to solution B. Which of the statements below does not agree with this information?
A. solution B has a higher water potential than solution A
B. water will tend to move from solution B to solution A through the membrane
C. Solution A has more solute than solution B
D. Solute wants to move from solution B into solution A, but is stopped by the membrane.
Answer:
D.
Explanation:
When a solution is hyper tonic,it means that it has higher concentration than the surrounding environment.Therefore more solute should be preset in it with less water molecules.Such a solution is said to be of higher solute potential,but low water potential. This is the state of A in the question.
The surrounding environment of lower concentrations should contain less solute more more water,and therefore said to be hypo tonic to A and thus higher water potential.
Hence,based on the concept of osmosis,water tends to move from higher water concentration from B to A, and not the movement of solutes from A,because,A is of less water potential ,therefore no solution to move the solute across the semi permeable membrane to the B.
What is the typical F2 ratio in the case of dominant epistasis?
Answer:
12:3:1
Explanation:
The typical F2 ratio in cases of dominant epistasis is 12:3:1.
The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus. There are different types of epistasis depending on the type of alleles that are interacting. These include:
Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.Other types of epistasis include recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).1.

Gravitational attraction provides the centripetal force needed to keep planets in orbit around the Sun and all types of satellite in orbit around the Earth. This means gravity makes the Moon accelerate all the time, even though its speed remains constant.
Explanation:
Answer:
The acceleration due to gravity depends on the mass of the body, the distance from the center of mass, and a constant G, which is called the "universal gravitational constant". ... The acceleration due to gravity on the surface of the moon is 1.620 m/s2. 2) The radius of the Earth is 6.38 x 106 m.

Review the ball-and-stick models of organic molecules. How can you tell the difference between between the glucose chain and the fructose chain?
The glucose chain contains 6 carbons, while the fructose chain contains only 3.
The glucose chain contains an aldehyde functional group, while the fructose chain contains a ketone functional group.
The glucose chain contains 1 double bond, while the fructose chain contains 2 double bonds.
Answer:
The correct answer is - The glucose chain contains an aldehyde functional group, while the fructose chain contains a ketone functional group.
Explanation:
Glucose and fructose both are simple monosacchrides that have the same molecular formula with 6 carbon chains and both sugars contain double bonds at the end of the chain.
Fructose have a ketone functional group end of the 6 carbon chain of the molecule whereas the glucose carries an aldehyde group as the functional group in the molecule.
