D. The octupus population would decrease.
This is because if more sharks were in the ecosystem than they would feed on more octopus, decreasing the population of them.
Answer: 100mL sucrose solution and 900mL water
Explanation: sucrose solution is 500 mM, i.e. 500mmol/L
water is 0mmol/L
To get 50mmol/L we need 1/10 L of sucrose solution = 100mL
and made up to 1L with water
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.
Explanation:
The production of egg and sperm cells follows a certain sequence of events.
The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.
Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.
Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.
