Answer:Ultraviolet radiation. Invisible rays that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer. UV radiation is made up of three types of rays -- ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC).

Explanation:Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays.

Varvara68 [4.7K]

Answer:

There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding

Explanation:

An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.

Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding.

What is Electron Transport?
Murljashka [212]

Answer:The electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. The electron transport chain is built up of peptides, enzymes, and other molecules

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Andrews [41]

The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.

a)

  • When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain.
  • This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next.
  • Further deterioration will occur when these herbivores are consumed by secondary consumers.
  • Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.

b)

  • Additionally, the energy flow in a food chain adheres to the 10% law.
  • This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.

c)

  • There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms.
  • Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.

d)

  • For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.
  • When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.
  • Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.
  • Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.
