David created a shoe box model of a grassland. He placed biotic factors in first but needs to add some abiotic factors. Which two abiotic factors could he add? A. Trees, B. Sunlight, C. Insects, D. Flowers, E. Humans, F. Water.
He placed biotic factors in first but needs to add some abiotic factors, two abiotic factors could he add Sunlight and Water.
What are abiotic factors in an ecosystem?An ecosystem is a place where biotic factors (that have a life) and abiotic factors (that have no life) converge, for the balance of the ecosystem both are necessary.
For example, in an ecosystem, animals and plants are the biotic factors, and among them, there are relationships such as animals that feed on other animals or others that feed on plants. But this life would not be possible if there were no factors such as water, sun, soil, oxygen, among others. So, the correct answer is C.
Thus, option "B and F" is correct.

the sequence of events that produces another generation of organisms.
The sequence of events which produces another generation of organisms is called as the Life cycle.
What is Life cycle?Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.
In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.
Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.

a signal molecule which can bind to an enzyme and shut down its activity by altering the shape of the enzyme.
Answer:
Enzyme inhibitor
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.
