Answer:
Explanation:The bird population would decrease
explain ways in which environmental factors contribute to evolution by natural selection?
pls help i have a test tomorrow
Answer:
The genetic variability created by a mutation will be tested by natural selection, which determines what characteristics are inherited in a population over time.
Explanation:
Beneficial mutation are passed on and harmful mutations
are eliminated as organisms adapt to changing environmental conditions and evolve.

The body absorbs nutrients through the small intestines. The blood transports these nutrients to every cell in the body. The blood also carries oxygen to every cell. The cells use the nutrients and oxygen to supply the energy the body needs. What three body-systems are working together in this situation?
A. nervous, digestive, and circulatory systems
B. digestive, circulatory, and excretory systems
C. respiratory, circulatory, and digestive systems
D. circulatory, immune, and respiratory systems
Answer:
(C) Respiratory, circulatory, and digestive systems
Explanation:
In this example, the respiratory system is being used because oxygen specifically is being transported through the bloodstream to the body. The way that oxygen enters the body and is stored until the blood can pick it up is of course through breathing! Another word for breathing is respiration and this involves the lungs, which all points to the respiratory system.
The circulatory system is being used due to the fact that blood specifically is being used to transport these nutrients and oxygen around the body. Blood passes through veins and arteries through the body and is all a part of the circulatory system!
Lasty, the digestive system is being used because the small intestines are absorbing nutrients and the intestines are where a majority of digestion takes place (hence, the digestive system).
Answering questions like these, or any question about body systems, means you need to know about what each system is and what it does. It can help to think about what body parts each system includes and one or two key words involved with that system. Ex. CIRCULATORY: blood. CARDIOVASCULAR: heart, capillaries, veins, arteries, pumping blood
In the given situation, the respiratory, circulatory and digestive systems are working together.
Working of the body systems:In the given case, as oxygen is mediated through the bloodstream in the body, therefore, respiratory system is being used. The blood is being used to mediate oxygen and nutrients all through the body, therefore, circulatory system is being used.
Blood is moved via arteries and veins throughout the body, which is a component of circulatory system. In the given case, as the small intestines are used to absorb nutrients, and it is the place where maximum of the digestion process takes place, therefore, digestive system is also taking part in the process.
Thus, the correct answer is option C.

How will the dam most likely affect the ecosystem around the river?
Answer: Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.
Hope this helps
