Answer:
Yes.Explanation:
If we want to "disable" astham attacks, that would imply too many restictions for those people who can suffer from these attacks. For example, in order to avoid these attacks, they couldn't do sport activities, because that would alter their respiratory system, which occasionate astham attacks.
Therefore, this statement is true.
Describe the relationship between the direction of the velocity vector and the direction of the acceleration for a body moving in a circle at constant speed.
The corn plants in the image below have been grown with Lepidoptera sp. larvae, insects that feed on the corn’s cob and leaves. Select the statement that is correct, based on the image.
A. A resistance gene was inserted into the plant on the right, but the corn is still vulnerable to Lepidoptera sp. larvae.
B. A resistance gene was inserted into the plant on the right that makes the corn resistant to Lepidoptera sp. larvae.
C. A resistance gene was inserted into the plant on the left that makes the corn vulnerable to Lepidoptera sp. larvae.
D. A resistance gene was inserted into the plant on the right, but the corn cob is mutated.
Answer:
Option D is correct
Explanation:
The image on the left is the control plant which means it is the normal plant that is allowed to grow under normal regular condition so that its parameter can be compared with the parameters of the transformed plant on the right. Thus, plant on the right has been introduced with the resistance gene and hence it possess mutated cob and leaves that are not attacked by the Lepidoptera sp. larvae
Hence, option D is correct
What will happen when the force on an object increase
As SCUBA divers go deeper underwater, the pressure from the weight of all the water above them increases tremendously which compresses the gases in their blood. What happens to the volume of gas in their blood as the diver rises quickly to the surface?
A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
B.
As a diver rises, the pressure on their body increases which allows the volume of the gas to decrease.
C.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to increase.
D.
As a diver rises, the pressure on their body increases which allows the volume of the gas to increase.
Answer: A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
Explanation:
The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.
The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.

Explanation:
A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw
based on this description?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field,
The electric field points to the right because the force on a negative charge is in the same direction as the field,
No conclusion can be drawn because the sign of the charge creating the field is unknown,
No conclusion can be drawn because the amount of charge on the test charge is unknown.

When tectonic plates are strained to the point that they can no longer bend, which of the following is most likely to occur?
A. Earthquake
B. Volcanic Eruption
C. Convection Current
D. Ocean Basin Formation
When tectonic plates are strained to the point that they can no longer bend, (A) earthquake most likely to occur.
What is earthquake?An earthquake is the sudden release of energy from the earth's crust that causes the earth's surface to shake. Seismic waves, also called S waves, are consequently produced. The type and severity of an earthquake are based on the local seismic activity.
What is Volcanic Eruption?A volcanic eruption occurs when elements of the Earth, such as hot lava, rocks, and dust, erupt from a volcano in the form of an explosion. The upper portion of the volcano or one of the side branches may explode. If massive volumes of rock and volcanic ash begin to erupt, it might be dangerous. Occasionally, numerous lives are lost in these explosions.
When tectonic plates are strained to the point that they can no longer bend, in such scenario, earthquake is most likely to occur.

Which are descriptions of gravity on Earth? Check all that apply.
an attractive force
a repulsive force
a noncontact force
a contact force
a horizontal force
a vertical force
Answer:
an attractive force
a noncontact force
a vertical force
Explanation:
Gravitational force is a NON-CONTACT FORCE. Gravitational force acts on all bodies on the earth that have mass. The force which is exerted through weight acts on the center of gravity of the body. The force is directed towards the center of the earth. The weight of a body is the gravitational force exerted by the earth on the body.

Answer: Schrodinger
Explanation: because Schrodinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This atomic model is known as the quantum mechanical model of the atom.
Schrodinger because Bohr's model was not completely correct, but it has many features that are approximately correct and it is sufficient for much of our discussion.
What needs to be the relation between the two forces to cause the upper magnet to float without moving?
Answer:
If it points the other way, the fields subtract, for a lower energy, and so the magnet prefers to turn to point in this way. Magnets in uniform fields feel torques which make them turn around if they are not pointing in the right direction, but there is no net force making the magnet want to levitate.
Explanation:
1. When an object moves it acquires
(a) friction
(b) traction
(d) speed
(c) energy of motion
When an object moves it acquires energy of motion. An thing that is in motion gains energy of motion, often known as kinetic energy. The energy an item possesses as a result of its motion is known as kinetic energy.
The item accumulates kinetic energy when it moves faster or at a specific velocity. The mass and speed of the item affect the quantity of kinetic energy.
Kinetic energy is calculated as KE = 0.5 * mass * velocity * 2. Because of the direct connection between an item's speed and the energy required to move it, the kinetic energy of an object grows exponentially as its velocity rises.

A concave mirror forms a real image at 15.0 cm from the mirror surface along the principal axis. If the corresponding object is at a distance of 30.0 cm, what is the mirror's focal length? Please show your work
Answer:
Focal length, f = 10 cm
Explanation:
We have,
A concave mirror forms a real image at 15.0 cm from the mirror surface along the principal axis, it means that the image distance is 15 cm
The object is placed at a distance of 30 cm, u = -30 cm
It is required to find the focal length of the mirror. Let it is f. Using mirror's formula to find it:
[tex]\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}\\\\\dfrac{1}{15}-\dfrac{1}{(-30)}=\dfrac{1}{f}\\\\f=10\ cm[/tex]
So, the focal length of the mirror is 10 cm.
