exercise. Choose ten learners in class who are willing to participate in this activity
They are the runners. Each of these runners must choose a classmate who will
measure his or her pulse rate.
Write down the question you are trying to answer in this investigation.
1.Write a hypothesis about the relationship between exercise and heart rate.
Answers
Answer:
Exercise is responsible for the increasing heart beat.
Explanation:
Exercise is responsible for the increasing heart beat because our body needs oxygen more faster during exercise. When we exercise our body needs quick energy and oxygen which can be provided by heart as well as the heart also removes carbondioxide which is produces during respiration process so the heart beat increases in order to provide energy and oxygen to the muscles.
Overtime, plants will compete, and recreate the forest.

Touch the stigma and notice how it feels. What is the advantage of this type of texture?
A. The sticky texture allows for capture of prey to help with fertilization.
B. The sticky texture allows for the exchange of carbon dioxide to assist with photosynthesis.
C. The sticky texture allows for pollen to adhere to the stigma for fertilization.
D. The sticky texture allows for water molecules to not escape from the plant, thus preventing dehydration.
Answers
Answer:
C. The sticky texture allows for pollen to adhere to the stigma for fertilization.
Explanation:
The flower is the reproductive structure of a plant. The STIGMA is a part of the female reproductive system, which is known for its function to receive pollen grains from the male flower during pollination. However, according to factual information and as stated in this question, stigmas are sticky to touch.
The major advantage of this stickiness of stigma is that it allows pollens from the male flower to be strongly adhered to the stigma in order for fertilization to occur.

1. A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
2. Coral snakes are brightly colored, highly venomous snakes with red, yellow, and black bands along their bodies. Another species of snake, called the scarlet king snake, has similar bands of red, black, and yellow. Which of the following describes the conditions that resulted in a large population of king snakes with these types of markings?
King snakes and coral snakes relied on similar food sources that contributed to their unique coloring.
Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.
Coral snakes mated with king snakes often enough to produce another species of king snake with the red, black, and yellow.
Overproduction of offspring increased the likelihood that the genetic mutation leading to these bands would spontaneously occur.

Just as slow-moving water loses sediment, fast-moving water can pick up new sediment to carry. Which part of the river
bend will experience the greatest amount of new erosion? How will this erosion affect the shape of the river?
Answers
Answer:
The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.
The water flowing at the maximum velocity and with the greatest ability to erode is on the outside of the curve, rivers that meander erode in both directions.
What factors affect the river?Cut bank erosion occurs when the edge of a stream channel bends, and it increases the loop of the meander, water that moves more quickly has greater kinetic energy.
It can therefore transport bigger particles, more articles may also be carried by it, and bigger and larger particles can be carried by a stream as it moves more quickly. The capacity of a stream increases with the size of the particles it can transport.
Therefore, a stream will have a quicker velocity if it has a steep slope or gradient, which implies it may transport heavier items in suspension.

Which theory directly
contradicts the concept of
absolute zero?
A. Gravitational Theory
B. Kinetic Theory
C. Matter Theory
Answers
A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.
What theory directly contradicts concept of absolute zero?All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).
Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.
Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

What is the relationship between capillaries and lymph vessels
Answers
Answer Blood vessels deliver oxygen and nutrients to virtually all cells in developing mammalian embryos and adults, whereas lymphatic vessels drain the interstitial fluid that collects in tissues, and serve as a conduit for immune cell trafficking and fat absorption.
: Lymphatic capillaries collect lymph fluid from the tissues, which allows them to regulate the pressure of interstitial fluid. This fluid is essentially plasma that leaks out of cardiovascular capillaries into the tissues due to the forces of hydrostatic or oncotic pressure.

The Haunted Forest
Once upon a time there was a family, made up of two young ones and their parents, traveling by road to road. One day the car broke down in the forest. The parents went out to get help, and so the children would not get bored, they left them with the radio on. It turned night time and the parents still did not return. Then suddenly they heard the disturbing news go on in the radio: A very dangerous killer had escaped from a prison near the forest. Hours passed and the children's parents did not come back. Suddenly, they began to hear something really loud. ¨Bang, Bang, Bang¨. They heard that which seemed to come from something hitting the top of the car. Then, the sound became louder and louder every time. ¨BANG, BANG, BANG¨. The terrified children could no longer resist. They opened the door and ran in a hurry. Only the eldest of the children dared to turn his head to see what caused the loud noise. He should have not done it though, there was a large and scary man on top of the car, who hit the top of the vehicle with something on his hands, they were the heads of his parents! The children began to run even faster and the large man began to run towards them. The children ran into the forest and so did the large man. After that day no one ever saw those children ever again, and who knows, they may appear mysteriously next to you.
