No further information is available so the answer will include the common orders by which the experiment was performed.
Answer:
Mendel is known as the father of the genetics and works on the pea plant Pisum sativum to explain the genetic laws.
The pea plant was selected by the Mendel because pea plant has short life cycle and both pollination are possible in the pea plant.
The monohybrid cross explains the law of segregation and the concept of dominance in the plants.
The dihybrid cross explains the law of independent assortment to explain the segregation of the different alleles.
Answer:
C. The basic effect of the cholera toxin is signal amplification.
Explanation:
Cholera toxin can cause its symptoms by amplifying the signals responsible for intestinal electrolyte transport through the following process:
The toxin binds to a membrane ganglioside (a phospholipid with carbohydrate residues) in the secretory cells in the small intestine. After that, a toxin subunit penetrates the cell, causing permanent activation of a G protein.
G protein activates adenylate cyclase, which catalyzes the formation of cAMP (A type of secondary messenger, important in signal transduction in cells), responsible for activating protein kinases.
Proteins undergo phosphorylation, this process amplifies chloride ions (Cl⁻) secretion.
The flow of negatively charged chloride ions out of the cell causes positively charged sodium ions to follow them in the flow.
Then water follows the electrolytes to the lumen of the small intestine by osmosis, resulting in severe diarrhea.
A mass extinction is when a certain group of animals or species suddenly die in large quantities with little to no hope of having a large birthrate to rebalance the losses.
This would have large effects on other parts of the food chain, and would lead to many species overpopulating and then drastically dying off

Answer: Estuaries are often protected from severe ocean conditions but depend on the currents created by tributary streams, long shore currents, and tidal fluctuations to cycle nutrients and provide a transportation mechanism for organisms such as shellfish, eels, and turtles during some stages of their life cycles. brainliest?
Explanation:
Answer:
C
Explanation:
Mitosis is a growth division unlike meiosis which an organism undergoes to produce gametes or sex cells during sexual reproduction.
Mitosis is a kind of cell division that results in two daughter cells, identical in genetic composition. An organism can undergo mitosis in asexual reproduction. For each mitotic division, two daughter cells emerge (duplication division), which will propagate the number of the species.
In a case of heavy predation, the prey organism will depend on diverse number to keep its species from getting extinct. Hence, undergoing mitosis to duplicate itself asexually will be most beneficial in this scenario as a large number will increase the chance that some of them will not be a victim of predation.
