Which evidence supports the idea that life on Earth has continually evolved
Answer:
Fossils are the remains of long-dead organisms, preserved in rock. Because rocks are laid down in layers, one on top of the other, the fossil record is generally set out in date order: the oldest fossils are at the bottom. Running through the fossil record makes it clear that life has changed over time.

which target organ releases glucose into the blood-stream as a result of the action of adreline?
a) adrenal gland
b) kidney
c) liver
d) pancreas
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?
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:

Tay-Sachs disease is a genetic disorder that results in the destruction of neurons due to a buildup of sphingolipids in the cells. Which organelle is malfunctioning in Tay-Sachs
Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.

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

4.) are insects a fool-proof way to determine time of death? Why or why not?
5:) why are family members or law enforcement personnel sometimes interested in having people live dr bass take a look at a cold case?
Answer:
1. When Dr. Bass works cases, either cold cases or ongoing investigation, what is his role in the investigation?
Dr. Bass’s role in an investigation is helping to identify the body and giving clues on how they died or how long they have been dead.
2. What role does the Body Farm play in forensic science?
The Body Farm plays an important role in forensic science because it has given all possible education and information on the decomposition of bodies.
3. What is the “sniffer”? Why could this development be important?
The sniffer is a mechanical device that you carry in your hand and walk across the grounds of the Body Farm. The sniffer will pick up some compounds of decomposing bodies.
4. Are insects a fool-proof way to determine time of death? Why or why not?
Insects are a great predictor of how long a body has been dead if the body is outside where the insects can get to it.
5. Why are family members or law enforcement personnel sometimes interested in having people like Dr. Bass take a look at old cases?
Family members and law enforcement personnel are sometimes interested in having someone like Dr. Bass because a forensic anthropologist can help solve and close cold cases even if decades have gone by.
