Answer:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
Explanation:
Answer:
1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

1) What is the control group? 2) What is the experimental group? 3) What is the independent (manipulated) variable? 4) What is the dependent (responding) variable? 5) What should Tina's conclusion be?
Complete question:
Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
1) What is the control group?
2) What is the experimental group?
3) What is the independent (manipulated) variable?
4) What is the dependent (responding) variable?
5) What should Tina's conclusion be?
Answer:
Individuals from test 1Individuals from test 2CaffeineHeart rateTina´s hypothesis is correct. Caffeine increases the heart rate of an earthworm.Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one affected by the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually represented using the letter Y. Controlled variable: Refers to the variables that have no influence on the results. These variables do not affect the change in the dependent variable values.1) What is the control group?
Individuals from test 1 compose the control group. They are not affected by the treatment. Tina just uses them to measure the normal heart rate and to compare them with individuals from test 2.
2) What is the experimental group?
Individuals from Test 2 compose the experimental group. They are affected by the treatment. Tina drops caffeine on their skin to see how it affects the worms.
3) What is the independent (manipulated) variable?
Caffeine is the independent variable. Tina manipulates the number of drops she places on the worm´s skins.
4) What is the dependent (responding) variable?
Heart rate is the dependent variable. Tina evaluates how the heart rate changes in individuals with or without caffeine.
5) What should Tina's conclusion be?
Caffeine increases the heart rate of an earthworm. It changes from 50 to 68 bpm. Tina´s hypothesis is correct.

Linkage and crossing over are inversely related.
Two new products are competing for grant money, with the goal of cleaning up the marine environment. Each product removes plastic from the ocean.
Product 1 can be used in the open ocean and requires monitoring once every three months to retrieve collected plastic.
Product 2 is designed to be used in harbors and marinas and requires monitoring once per week to retrieve collected plastic.
If all other costs and benefits are equal, which of these products would you recommend for the grant?
A. Product 1 because it requires less monitoring, reducing the overall cost
B. Product 1 because it is presumed to be more effective at removing plastic
C. Product 2 because it would provide more job opportunities for local people
D. Product 2 because it would probably last longer in marinas than in the open ocean
Answer:
A. Product 1 because it requires less monitoring, reducing the overall cost
Explanation:
Product 1 is more favorable to use than product 2, because its need for monitoring and maintenance is less. This allows the cost of plastic collection to be lower, assuming the subsidy money would be spent more optimally, promoting savings while promising results are observed at sea. In other words, product 1 promotes efficient cleaning at a lower cost, while product 2 promotes efficient cleaning at a higher cost.

According to the author, how has the almond tree
monoculture affected honeybees in Central Valley,
California? What evidence is provided to support the
claim?
I
Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try and help as best I can.
The only way you can answer this question is by reading the text. During this reading, you will notice that there is an element in monoculture that is harming bees, making them have a very difficult life or even die. This element is what is affecting the bees. The author will show why this element is harmful to bees through sentences that prove the effect that this element promotes and how it only exists in monocultures. These sentences will be the text evidence.
It is likely that the author shows how monoculture requires a large use of pesticides, which ends up harming the life of bees. He can also show that monoculture decreases the availability of food for bees, since all monoculture plants only flower once a year and leave the bees without food for the rest of the year, as there is no plant diversity in the monoculture.
Answer:
sample response
Explanation:
Because of the growth of the almond trees, many honeybees have died. Honeybees do not naturally live near the trees so they are transported to the area in order to pollinate the trees. However, the bees are exposed to pesticides that are used on the trees. Many also likely die because the almond trees only bloom in February, so the bees do not have enough food for the rest of the year.

The cells that make xylem have an ability to adapt according to the environment. They open up, lose their ends to make a hollow vessel, and they get strength by lignin, it also supports the plant.
What is xylem vessel?Xylem vessel is a vessel type structure present in plants, that hold water for the plant. They are small vessels, and they loose and tight according to the requirement of water of the plant.
Its main function is to transport water and nutrition. It also supports the plant and give strength to tissues and stems.
Thus, the cells that make up xylem have the ability to adapt to their surroundings. They open up, shed their ends to form a hollow vessel, and lignin provides strength and support to the plant.

How do light intensity and distance affect the rate of photosynthesis? How do you know?
Answer:
Light provides the energy needed for photosynthesis. Increasing the light intensity increases the rate of photosynthesis, provided plenty of carbon dioxide and water are available. ... This states that the intensity of light is inversely proportional to the square of the distance from the source.
