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.

Explanation:
Hope this helps
The examples of natural selection are as follows:
Giraffes develop longer necks over time.A Non-poisonous snake mimics a poisonous snake.Galapagos finches choose mates with stronger and longer beaks.Peppered moths choose mates with darker colors.Thus, the correct options for this question are B, C, F, and H.
What is Natural selection?Natural selection may be defined as the methodology through which organisms that are better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. The concept of Natural selection was first proposed by Charles Darwin.
According to the question, due to the requirement of long necks in order to get food from longer trees, Giraffe develops longer necks. In order to protect themselves from predators, a non-poisonous snake mimics a poisonous snake.
On Galapagos island, if there were variations in the finches of the bird, they get a variety of food resources in order to get more nutrients and energy for survival and reproduction.
Therefore, the correct options for this question are B, C, F, and H.

Answer:
Death of coral reefs occurs due to increasing the temperature of the ocean.
Explanation:
Death of coral reefs occurs due to increasing the temperature of the sea and ocean because warm water killed the algae attached to the surface of coral reefs which causes bleaching of coral reefs. This coral reefs provides habitat as well as food to thousands of animals present in the ocean ecosystem so the destruction of coral reefs causes death or migration of animals from that region.

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.

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 :)
