Explanation:
The greenhouse effect is a natural proccess that allows the development of life, it has natural causes. On the other hand, the enhaced greenhouse effect, also know as climate change or global warming, it's reffered to the impact on the climate caused by the overheating of the Earth's surface because of the human activity. Then, option D is correct.
Answer:
50% long black hair and 50% short hair
Explanation:
Attatched is a screenshot of a punnett square that shows the possibilities of the offspring having long or short hair. In short, the genetics of long black hair only need one big "L", while the genetics of short hair need to have 2 short "l"s. So when we draw the punnett square and combine the genetics, we get 50% have Llbb, and 50% have llbb
Answer:
The correct answer is: The action potentials peak at a higher voltage than in the body.
Explanation:
Nerve cells in the human body have a very low sodium concentration inside them, while the liquid that surrounds them is rich in this particular ion. When sodium channels in the neuron's plasma membrane are opened, this big difference in sodium concentration -also called gradient- produces a big influx of sodium ions. This rapid entering of Na+ generates a change in the voltage of the cell, because sodium is positively-charged, meaning that the inside of the neuron will become less negative - this is commonly called depolarization of the membrane. Action potentials are generated because of the sudden spike in voltage, but for them to occur, there's a certain voltage that needs to be achieved, so not every depolarization will produce an action potential.
The fact that the cell in the lab is surrounded by a lower concentration of sodium means that the influx of Na+ ions will be lower, because the gradient won't be as big, but also means that the action potential will peak at a higher voltage because the resting membrane potential wasn't as negative to begin with.
B.Blastocyst
C.morula
D.Blastocoel
Ans.
Embryogenesis or embryonic development is defined as a process that involves formation and development of a zygote into embryo. The fertilized egg or zygote undergoes mitotic divisions through cleavage and divides rapidly.
The first stage of embryonic development is known as morula that represents a 16 cells consisting solid ball-like structure. The morula later develops into blastula.
Thus, the correct answer is option C). 'morula.'
