The enzyme and the substrate form an enzyme-substrate complex. The enzyme and the substrate form an enzyme-substrate complex
Answer: it’s wastes
Explanation:
All cells need these key 7 things in order to function, movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.
This spells the acronym MRS GREN.
Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.
Answer:
Approximately 25 arteries would branch off
Explanation:
Aorta has a diameter of 2 cm, so area is pi x 1^2 = 3.142
In case of the artery, pi x 0.2^2 = 0.126
So dividing total area of aorta by total area of one artery, we get 3.142/0.126 = 25.021
Hence, about 25 arteries will be needed to carry the amount of blood that flows in the aorta vessel.
Answer:
Difference:Bacteria cells are very different from animal, plant or fungal cells. They don't have organelles such as nuclei, mitochondria or chloroplasts. Although they do have ribosomes and a cell wall, these are both different in structure to the ribosomes and cell walls in the cells above.
Similar:Plant cells and bacteria alike have cell walls, strong flexible layers surrounding their cell membranes that help to counteract osmotic pressure so the cell does not burst as water diffuses into it.
