Using Figure 4, which of the following best describes the interaction that occurs between a plant’s reproductive parts during self-fertilization?
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.
Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.

monocot.

Seeds and fruit carry out which type of reproduction?

What is the function of phloem in terrestrial (land) plants?
transports sugars down from the leaves
transports water and minerals up from the roots

Several factors influence the rate of photosynthesis. Which of the following is a reasonable conclusion from the data represented in graphs I, II, and III?
Photosynthesis does not occur at point A regardless of CO2 levels, light intensity, and temperature.
In graphs I and II, the rate of photosynthesis reaches a plateau regardless of increases in CO2 concentration and light intensity.
As the rate of photosynthesis increases, the production of oxygen decreases from A to B in graphs I, II, and III.
Increasing temperature, light intensity, and CO2 levels have the same effect on the rate of photosynthesis.
A gardener noticed that his plants were not as tall this year as they were last year. He hypothesized that his soil was deficient in nitrogen. He treated half his plants with nitrogen containing fertilizer and left the other half untreated. What was his purpose in leaving half the plants untreated.
his experiment must be completed during the light portion of the day
he hypothesized that the nitrogen would diffuse through the soil to the other half of the plants
he could only have one variable at a time
he needed a control setup to compare the treated plants to
According to the chart, at what taxonomic level do the dandelion and desert honeysuckle diverge (separate)?
Class
Order
Family
Genus
When plants bend toward their light source, how does this help them?
It heats internal nutrient solutions, thereby making their transport easier.
It heats enzymes by increasing the rate of metabolic chemical reactions.
It maximizes exposure to light, thereby increasing the rate of sugar formation.
It maximizes transpiration by increasing the rate of carbon dioxide dispersal.
The life cycle of a mosquito depends on the availability of standing or slow moving water. If there is a lower than normal number of mosquitoes present in an area, which limiting factor is most likely the cause?
a severe drought
mild temperatures
a reduction in pesticide usage

Example Lake Ecosystem
An increase in phosphate levels in a lake increases the population of algae in the lake. Increased algae blocks sunlight into the lake and results in a decrease in dissolved oxygen in the lake’s water.
What is the limiting nutrient for the lake?
Oxygen
Nitrogen
Phosphorus
Hydrogen

Cattle egrets are birds that live near large grazing animals. They feed on insects that are exposed as the grazing animals walk through grass.

Cattle are not affected by cattle egrets.
Cattle are seen feeding on cattle egrets.
Cattle egrets begin to eat ticks living on cattle.
Cattle egrets begin to draw nutrients from cattle.
Which statement best describes the relationship between biodiversity and environmental conditions in an ecosystem?

The ant population would decrease.
The dragonfly population would increase.
The sedge population would decrease.
