Answer:
D. Meiosis is the only source of genetic variation for sexual reproduction
Explanation:
Sexual reproduction is the form of reproduction that involves two parent organisms which produce gametes or sex cells that unite while asexual reproduction involves only one parent to occur. One advantage of sexual over asexual reproduction is that there is room for genetic VARIATION among offsprings produced.
However, this genetic variation occurs in sexual reproduction as a result of a process called CROSSING OVER in MEIOSIS. Meiosis is the only division that produces gametes in living organisms and it only occurs in sexually reproducing organisms.
Answer: If red light is shined on a population of red walking beans then they would not be as red as when started because they need light to survive and red light is present but they reflect it until they need it to survive.
Mutations that naturally occur can change phenotype and if it is beneficial to the species then it will be past on if it is no then it will die before passing it on.
Answer:
A longitudinal wave is characterized by COMPRESSIONS and RAREFACTIONS.
Explanation:
Answer:
The correct answer is "excretes; hypotonic; absorbs, hypertonic".
Explanation:
Cell's homeostasis is only conserved in an isotonic solution, since cells that are in an hypertonic solution (high salt concentration) tend to loss water, and in hypotonic solution (low salt concentration) tend to absorb water. Brine shrimp lives in waters that are both, hypertonic and hypotonic and has adapted to overcome this issue by excreting and absorbing salt across its gills. In very high salt concentrations, a brine shrimp "excretes" salt across its gills and maintains an internal salt concentration that is "hypotonic" relative to the water where it lives. In lower salt concentrations, a brine shrimp "absorbs" salt water across its gills and maintains an internal salt concentration that is "hypertonic" relative to the water where it lives.
with the prey there is always going to be something that is going to eat them it is called the food chain
