Answer:
A scientific law predicts the results of certain initial conditions. It might predict your unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle. In contrast, a theory tries to provide the most logical explanation about why things happen as they do. Organic molecules mainly have covalent bonds whereas, in inorganic molecules, there are covalent and ionic bonds. • Inorganic molecules cannot form long chained polymers as organic molecules do.Explanation:

Explain why a seismic station on the opposite
side of the Earth may receive P-waves from an
earthquake, but not S-waves.
Answer:
P-waves travel faster than S-waves.
Explanation:
P-waves can go through solids, liquids, and gases. This allows them to go through the earth. Meanwhile S-waves shake the ground going crosswise and can only travel on the earth's crust.

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.

An adaptation is __________.
A. an individual's attempt to conform to its environmentthe cause of natural selectiona trait that gives rise to a new species
B. All of the listed responses are correct.
C. a trait that gives an organism
D. a reproductive advantage in the current environment
Answer:
The correct answer is - D. a reproductive advantage in the current environment.
Explanation:
Evolutionary adaptations are the adjustments and alteration of the physical structures of the organisms or their traits according to the environment change and it is hereditary. These adjustments or changes help in improving its ability to survive and reproduce and increase its number to pass the genes.
In other words, Evolutionary adaptations are characteristics or traits that are hereditary and enhance an organism's ability to survive and reproduce in a particular environment.

A scientific__offers a scientific explanation about why something and is supported by a large number of experience
Answer: A scientific Hypothesis.
Explanation:
A scientific hypothesis is the initial building block in the scientific method. Many describe it as an "educated guess," based on prior knowledge and observation. While this is true, the definition can be expanded. A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association.

Answer:
Male reproductive organ is responsible for sexual function.
Explanation:
Male reproductive organ produces sperm which combines with eggs of female reproductive organ produces fertile offspring. The male reproductive system is mostly located outside of the body. The external organs include the penis, scrotum and testicles while on the other hand, internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as removal of waste material from the body.
Why are amino acids called “amino acids?”
They are subunits of macromolecules that act as both strong acids and strong bases in solution.
They are single molecules that contain both an amine group and a carboxylic acid group.
They are acidic and were first discovered by a Russian researcher by the name of Aminov.
Answer:
The name “amino acid” is derived from the amino group and carboxyl-acid-group in their basic structure.

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.
