Answers

The answer for this is the liver

The target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.

What is the importance of glycogen in the body?

Glycogen is a polysaccharide that is stored in the liver and muscles of the human body and plays a crucial role in maintaining the body's energy as well as glucose homeostasis. During exercise or physical activity, glycogen is broken down into glucose, which is then released into the blood as fuel; this is regulated by hormones such as insulin and glucagon and prevents hyperglycemia.

Hence, the target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.

What are the FIVE ways an object's motion can change?

Answers

Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.

Explanation: please can I get brainliest

Motion is defined as the phenomena where an object moves from one point to another. Usually, a force has to act on the object for it to be in a state of motion.

Mathematically, motion has to do with:

AccelerationDisplacementDistanceVelocitySpeedTime.

With this in mind, the five ways an object's motion can change include:

When the speed acting on the object changesWhen the force acting on the object changesWhen the acceleration changesWhen the velocity acting on the object changesWhen there is a greater displacement acting on the object.

Why is it important that the DNA is replicated during the S phase of interphase

Answers

Answer:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

A student kicks a soccer ball three times. Another student records the distance, the amount of time the ball travels, and the average speed in the table shown below. How many seconds did it take for the ball to travel 30 m during Kick 3?



F. 0.5 s

G. 1.0 s

H. 1.5 s

J. 2.0 s​

Answers

Answer:

2/j

Explanation:

formula: average speed= total distance/total time

                15=30/total time

                  30/15= 2

Hope this helped and good luck!!!

It would take 1 second for the ball to travel 30 m during Kick 3

Speed

Speed is the ratio of total distance travelled to total time taken. It is measured in meters per second. The formula for speed is given by the equation:

Speed = distance / time

From the question, average speed = 30 m/s, hence:

Average speed = distance / time

30 = 30 / time

time = 1 second

It would take 1 second for the ball to travel 30 m during Kick 3.
