Enzymes act as a catalyst they speed up reactions by providing a alternative pathway of lower activation energy by attaching to itself to its specific substrate and breaking down the energy required to start the process making it quicker.
And no they just speed the process up :)
I believe that the amount of carbon stored in organisms decreases as you move up the food chain. This is because carbon constitutes the biomass of an organism which decreases as you move upward the food chain. Each link in a food chain is known as a trophic level. Trophic levels represent a feeding step in the transfer of energy and matter in an ecosystem. Biomass is the amount of organic matter comprising a group of organisms in a habitat. As you move up a food chain, both available energy and biomass decrease. Energy is transferred upwards but is diminished with each transfer from one trophic level to the next.
Measuring photosynthesis via the production of oxygen. Oxygen can be measured by counting bubbles evolved from pondweed, or by using the Audus apparatus to measure the amount of gas evolved over a period of time.The emerging bubbles are either simply counted or they are recorded using light barriers, which is very difficult because of their small size and often varying ascent rate. The gas bubbles generated during photosynthesis by aquatic plants produce distinctive sound pulses when leaving the plants.
Answer:
a) genetic drift - yes
b) Natural selection - yes
c) Gene flow - yes
d) Mutation - yes
Explanation:
factor that alter the allele frequencies are
a) genetic drift - yes
b) Natural selection - yes
c) Gene flow - yes
d) Mutation - yes
Genetic drift - Alter occur due to sampling error or selecting error. in this some error occur while deciding for the allele for the next generation.
Natural selection - it is due to large number of one type of allele in the population
Gene flow - it alter because of migration of allele among the populations.
Mutation - it is strong for introduction of new alleles in the population
