What water cycle process moves water from land to streams
Answer:
The answer would be runoffs
Explanation:
Although water coming from land to streams isn't directly tied to the water cycle, runoffs are due to gravity.

During an experiment to determine if people with more symmetrical body features have a lower incidence of disease, a researcher first measures the length of several bones in the subject's hands and arms. The device used to measure length does not display a readout of the measurement taken. Instead, a wire connects the measuring device to a computer that records the data. The computer monitor is kept out of sight of the subject and the researcher. Why is such an elaborate device used?a. So that the subject will not know if he or she is part of the control group.b. So that the experiment will be repeatable.c. So that the subject will not be injured by the experiment.d. So that the identity of the subject will remain anonymous.e. So that the measurements are not biased by the researcher.
Answer:
e
Explanation:
The main reason such an elaborate device was used would be to eliminate any element of bias by the researcher.
It is important to eliminate biases when taking measurements so as to ensure the accuracy of the data and the overall outcome of the experiment. If a simpler device had been used in which the researcher manually records the length of the bones, it is possible to knowingly or unknowingly introduce biases or random error into the experiment which will impact the integrity of the data and the outcome of the experiment.
The correct option is e.

Which is the best hypothesis for the scientific question “How does light intensity affect the rate of photosynthesis?”
Answer:
A hypothesis for this question could be: If there is more light intensity on a plant then, there would be higher rates of photosynthesis.
Explanation:
Answer:
The answer to this question would be C.) If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.

Besides helping to discover the structure of DNA, describe two other contributions Rosalind Franklin made to the world of science.
Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.
Explanation:
Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.
What is the contribution of Rosalind Franklin?She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.
Hence, Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

please help, i’ll mark brainliest if you get it right! please please only answer if you know the answer though, don’t guess i’m taking a test and i can’t fail as it’s the last one before the quarter ends ( tomorrow ) id appreciate it!! thank youuu
Answer:
C. The salt is dissolved by the water
Explanation:
When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

The diagram shows a reflex arc. Name parts P and Q shown on the diagram above.
Please help.
Answer:
P - synapse
Q - Relay neuron
Explanation:
A synapse, easy to remember as a neural junction, is the site where the transmission of electric impulses occurs. This occurs between two neurons or between a neuron and a gland or muscle cell. So in this scenario when we poke the finger it fires an electric nerve impulse that gets to the P spot that is a synapse and gets transmitted to the relay neuron. A relay neuron is there to receive the signal from one neuron and then transfer it to another interneuron resulting in the signal being received by a motor neuron so that we can react to the stimulus.

When we breathe, we inhale oxygen and release carbon dioxide. What cell process does our body use the oxygen for?
A. Photosynthesis
B. Cellular respiration
C. Osmosis
Answer:
Cellular respiration
Explanation:
This is because if you see Photosynthesis is used for plants to get a food source from the Sun. Osmosis is the movement of chemicals from a less converted membrane to a more. I think i said that wrong but. I am sure it is cellular respiration which is the despirsion of waste products. So yeah Answer is Cellular respiration

a clams - a primary consumer
b. sardines - a primary consumer
c. sharks - a secondary consumer
d. kelp - a primary producer
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. In an energy pyramid, the energy flows from producers to consumers.
The organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).In an energy pyramid, the energy flows from producers (e.g., plants) to primary consumers (eg., herbivores). Subsequently, the energy then flows from primary consumers to secondary consumers (e.g., carnivores) and so successively.In an energy pyramid, the amount of available energy decreases as it moves through subsequent trophic levels.In conclusion, the organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).
