A sperm cell and an egg cell fuse to form which structure is called a <span>zygote. The zygote is a product of fertilization of two gametes: egg cells for female and sperm cells for males. In this process,the DNA of both cells is passed to the offspring to form a new individual. </span>
Answer:
As we know enzymes are specific for different reactions and The conditions required by an enzyme to function are also specific. An enzyme which works in a basic environment will not be able to function in a acidic environment.
If the pH for a reaction is increased from 2 to 11 then this change will change the active site of the enzymes. As a result, the substrate will not be able to fit into the enzyme and hence the enzyme will not catalyze the reaction.
Answer:
Initial age of ghost shrimp and water temperature
Explanation:
In an experiment, there are several variables (alterable factors) that determine the outcome of the experiment. A CONTROLLED variable or CONSTANT is a variable that is kept constant or unchanged throughout the experiment. The constant is not changed because it can affect the other variables (outcome) of the experiment.
For this experiment conducted by Mary Beth on the effect of size of the tank on the size of the shrimp after 6months, the constants are INITIAL AGE OF GHOST SHRIMP and WATER TEMPERATURE. This is so because the ghost shrimps of the same initial age must be used to start the experiment, so as to be able to measure the actual effect on the growth. Also, the water in the respective tanks must be the same Temperature so that one experimental group will not be favored over another.
