Two decades after the Emerald River Dam was built, none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.
Which of the following statements, if true, would most strengthen the scientists’ hypothesis?
(A) The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.
(B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish.
(C) The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees, whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.
(D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space.
(E) Five of the fish species native to the Emerald River are not native to any other river in North America.

The organs in the human body perform specific functions for survival.
Organ A delivers blood to the body
Organ B delivers oxygen to the body
Organ C delivers messages to the body
Which of the following correctly identifies the organs that perform each function above?
Organ A is the heart, Organ B is the brain, and Organ C is the lungs
Organ A is the heart, Organ B is the lungs, and Organ C is the brain
Organ A is the lungs, Organ B is the brain, and Organ C is the heart
Organ A is the lungs, Organ B is the heart, and Organ C is the brain
Organ A is the heart
Organ B is the lungs
Organ C is the brain
Because heart only delivers blood to lungs and other body tissues, Lungs input oxygen into the blood and brain sends signals and messages to the body parts.
This is the answer. Hope it helps you

Hello! I can't find the constants and am a little confused. Could you help me please??
Answer:
The constants are just variables that are kept constant throughout the experiment. For example, even though the question did not mention this, we can assume that sunlight is a constant, otherwise it wouldn't be a fair experiment.
Some of the constants could be...
- Sunlight
- Water
- Room temperature
- Hours of light
- Soil quality

Explain what will happen to your eyes when..
a) you move in a very bright light.
b) you move in a dim light
Answer:
For A your pupils will shrink for B your pupils will dilate.
Answer:
When you look at something that is bright, your pupil may shrink.
When you look at something dim, your pupil may get larger.
Explanation:
I think your pupil may get larger if you look at dim light because your eye may have a hard time seeing what's going on. And the opposite may happen when you look at bright light.
Explain how a person can be a carrier for a sex-linked disorder, but not exhibit this disorder.
A person cannot exhibit the disorder because they don't experience the condition because they have a healthy copy of the gene on their other sex chromosome.
A disorder is a functional abnormality or disturbance that affects an individual's physical, mental, or emotional health.
They have the potential to pass on the mutated gene to their offspring, but they do not exhibit the disorder themselves because they have a normal copy of the gene on their other sex chromosome.
In the case of X-linked disorders, females have two X chromosomes, while males have one X chromosome and one Y chromosome. Females can be carriers for X-linked disorders if they inherit one mutated X chromosome from one parent, and one normal X chromosome from the other parent.
Males, on the other hand, cannot be carriers of X-linked disorders because they only have one X chromosome.
Therefore, a person can be a carrier for a sex-linked disorder if they have one copy of a mutated gene on one of their sex chromosomes, but not on both.

Science deals with the natural world.
Answer:
All of the above are correct
Blood pH is sensed by cells known as chemoreceptors that send information about blood pH to the brain via cranial nerve 9 and 10. In order to correct changes in pH, the ventral respiratory group sends signals to the diaphragm to adjust its rate of contraction. These signals are sent via the phrenic nerve. What serves as the effector in this example
Answer:
The correct answer is - The diaphragm.
Explanation:
If there is a response to stimulation if a bodily tissue or organ becomes active and those of the autonomic system involves two neurons, not single neurons like motor pathways of the somatic nervous system.
In this case, the diaphragm is the organ that gets the signal in order to correct or adjust the rate of contraction in response to changes in pH level, Hence, the diaphragm is the organ that is the effector in this case.
