When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.

True
False
Answer:
False

Which of the statements regarding the nitrogen cycle is true? a. Denitrification occurs when a nitrogen containing compound is produced from nitrogen in the soil. b. Atmospheric nitrogen is absorbed through the leaves of plants. c. Nitrogen fixation is the process atmospheric nitrogen is converted into biologically usable forms. d. Animals obtain nitrogen through the process of cellular respiration
Answer: Option C
Explanation:
The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.
Then from animals and human beings it is again transferred into the soil and then atmosphere.
The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.

What does the theory of evolution tell us about living things?
A) The environment can make them change rapidly over a short period of time. B)They create fossils when they die
C)Their environment makes them change slowly over time.
D)They can give us clues about extinct species. (science 7th grade) (100 POINTS)
Answer:
Their environment makes them change slowly over time
Explanation: I took the test and got it correct.
The agents of wethering erosion deposition and the rock cycle will slowly change the fossils over time. They may damage them or burry them deep into the layers of earth. Over time, as they age, new landforms will me made ontop of them. This is why they use the fossils to determine the age of the land. I hope this helps :)

B. A way a life
C. One person giving another person power
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the change that happens over time in an ecological community. So, option (A) is the answer.
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.
There are two main types of succession, primary and secondary.
Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. For example, after felling trees in a woodland, land clearance or a fire.
