Answer:
A nonconformity occurs where layers of sedimentary rock are deposited over eroded layers of igneous or metamorphic rocks.
Explanation:
That nitrogen gases, hydrogen gas, methane, and ammonia were formed in the waters of the past.
B.
That water turned into various types of gases found in the earth's early atmosphere.
C.
That amino acids, fats, and nucleic acids might have formed in the waters of the past.
D.
That water turned into amino acids and fat, but nucleic acids were caused by lightning
The answer is C. That amino acids, fats, and nucleic acids might have formed in the waters of the past.
Answer: Fertilization.
Explanation: The male and female gamete fuse together to form fruit. After pollination and fertilization the carpels develops into the fruit.
The growth of fruit is initiated by the growth regulating hormones which is produced by the developing seeds.
The carpels develop into fruit so the number of carpels in a flower determines the degree of pollination and fertilization.
Answer:
Fertalizeation
Explanation:
During photosynthesis, carbon dioxide and water enter the leaf through the stomata and xylem vessels, respectively. They then move to the chloroplasts where they are converted into glucose and energy-rich molecules.
During photosynthesis, reactants enter the leaf through the stomata, which are small openings on the surface of the leaf. The main reactants for photosynthesis are carbon dioxide (CO2) and water (H2O). Carbon dioxide enters the leaf through the stomata, while water is taken up by the roots and transported to the leaves through a network of xylem vessels.
Once inside the leaf, the reactants for photosynthesis move to the chloroplasts, which are specialized organelles where photosynthesis takes place. Within the chloroplasts, CO2 is converted into glucose through a series of chemical reactions called the Calvin cycle. Water is split into oxygen and hydrogen ions, and the hydrogen ions are used to create energy-rich molecules called ATP and NADPH, which are used in the subsequent steps of photosynthesis.
In summary, the reactants for photosynthesis, carbon dioxide and water, enter the leaf through the stomata and xylem vessels, respectively. They then move to the chloroplasts where they undergo chemical reactions to produce glucose and energy-rich molecules.

True
Humans are in fact made up of eukaryotic cells.
Eukaryotic cells are cells that contain organelles surrounded by cytoplasm as well as a nucleus protected by a nuclear envelope. Prokaryotic cells refer to single celled organisms in which they are sufficient on their own.
B) they are having a positive impact on the environment by acting as decomposers.
C) they are having a negative impact on the environment by acting as decomposers.
D) they are having a predatory impact on the environment by acting as decomposers.
The correct answer is option B) i.e. they are having a positive impact on the environment by acting as decomposers.
By acting as decomposers beetles are helping in recycling of nutrients between biotic (organisms) and abiotic factors (enviroment). So, it may be considered as positive impact on the environment. Decomposers play a very important role in food chains and food webs. They breakdown biomolecules and liberate the micronutrients and micronutrients as inorganic molecules back to the environment. These inorganic molecules are used by plants once again to synthesize biomolecules. This is how nutrient cycle operates with the help of decomposers. For example, protein molecules of dead and decaying matter are broken down by decomposers to liberate nitrogen gas to the environment which is utilized by leguminous plants to make protein molecules again.
