F Galapagos finches choosing mates with stronger and longer beaks
H Peppered moths choosing mates with darker colors
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.

which examples represent abiotic factors affecting biotic factors? Check all that apply
Answer:
ash from a volcanic eruption kills new plant growth.
warm water from a nuclear power plant causes overgrowth of algae.
a river floods and deposits tree pollen along its banks.
Explanation:
Ecosystem consist of biotic and abiotic elements. Biotic refers to all living organisms while abiotic refers to all non-living elements of the environment. Living organisms depends on abiotic factors such as light, temperature, water and soil etc for their growth and survival. In the above answer, Ash of volcano, warm water and rivers are abiotic elements while plant, algae and pollen are biotic elements.
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.

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.

How does survivorship relate to an individual's fitness?
Answer:
Ecologists use survivorship curves to visualize how the number of individuals in a population drops off with time. In order to measure a population, ecologists identify a cohort, which is a group of individuals of the same species, in the same population, born at the same time.
The higher the survivorship of an organism, the higher the fitness of the organism
What is survivorship ?The term survivorship refers to the ability of an organism to live long in its habitat and reproduce. This is related to the fitness of an organism which is its ability to survive to the next generation.
Hence, the higher the survivorship of an organism, the higher the fitness of the organism and vice versa.
