Answer:
Stem tuber ---- Potato
Conditioned reflex ---- Pavlov's experiment
Blood circulation ---- William harvey
Pancreas ---- Insulin
Autotrophs ------ Blue green algae
Active transport ---- Minerals
Note: Chlorosis has no matching item in the list. Explanation is given below.
Explanation:
Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.
Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.
William Harvey discovered the circulation of blood and the function of the heart .
The islets of Langerhans found in the Pancreas secretes the hormone, insulin.
Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.
Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.
Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.

Why didn’t Darwin think you could observe natural selection in a lifetime?
Answer:
There aren't enough generations visible within a lifetime to have any visible changes or evidence of natural selection. Essentially, evolution takes much longer than 1 lifespan to happen.

Do plants undergo photosynthesis in a dark environment (not total absence of light)? If so, what would you expect to happen to the rate of photosynthesis?
Answer:
See explanation
Explanation:
In a situation whereby a plant is in an environment where light is not totally absent, the plant continues to photosynthesize at a slower rate.
Recall that photosynthesis is the process by which green plants make their own food in the presence of sunlight, chlorophyll, carbon dioxide and water.
In a low light, plants are forced to stretch towards the low light source. This is known as etiolation of plants.
True or false if false type the right answer. History

In Aquarium C, would the water level on the side with 30% solution of NaCl be higher, lower, or equal to the water level on the side with 5% solution? Explain
Answer:
In Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
Explanation:
The movements of molecules based on differences in concentrations of these molecules in different regions is explained by the phenomena of diffusion and osmosis.
Diffusion is the movement of moleculesmfrom regions of higher concentrationto regions of lower concentration until equilibrium concentration is attained.
Osmosis which is a special form of diffusion involving water molecules is the movement of water molecules in a solution across a semipermeable memebrane, from regions of high solvent concentration (low solute concentration) to regions low solvent concentration (high solute concentration) until equilibrium is attained.
A 30% solution of NaCl is more concentrated than a 5% solution of NaCl, therefore, water molecules will move across the semipermeable from the 5% solution to the 30% solution. This will result in a rise in the water level in the 30% solution.
Thus in Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
