Multiple choices :
A. test for chemicals that might poison fish and cause algae to grow
B measure the dissolved oxygen content in pond-water samples
C look for sources of pollution that may be affecting the pond
D measure the amount of light at various levels in the pond
Answer;
D. measure the amount of light at various levels in the pond
Fish in the pond feeds on the algae that grows in the pod.
Therefore; death of fish in the pond caused a large increase in algae populations.
Measuring the amount of light in the pond would not tell the student what caused the death of the fish in the pond.
Answer:
Dehydration synthesis is a chemical reaction that takes smaller, simpler molecules and combines them to form larger, more complex molecules with the removal of one WATER molecule. So, two monosaccharide (glucose) molecules come together and make a disaccharide (maltose).
Explanation:
Answer:
The two prokaryotic domains are Archaea and Bacteria.
The eukaryotic domain is Eukarya.
Both prokaryotic and eukaryotic are similar in which they have a plasma membrane and cytoplasm; meaning all cells have plasma membrane surrounding them. A difference between Eukaryotic and Prokaryotic is that eukaryotic have organelles, for example, a nucleus. Prokaryotic cells do not have a nucleus.
In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity. When a stimulus is applied to a sensory receptor, it normally elicits or influences a reflex via stimulus transduction.
Answer: Cardiovascular telex.
Explanation: During physical exercises which involves running, there is a reduction in the systemic vascular resistance produced and these constitutes a change in the heart rate and respiratory rate caused by the neural mechanisms which control the cardiovascular system which regulate the circulation of adequate oxygen supply and release carbon dioxide.
