Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
Answer: Pyruvate is reduced and NADH is oxidized.
Explanation:
Fermentation is a chemical process that involves the breakdown of carbohydrates anaerobically by the activities of microorganisms.
It is the process use in the production of foodstuffs, wine and beer. Fermentation start with enzymes activities, which breakdown sugars into lactate or two molecules of three carbon organic acid, pyruvic acid. Pyruvate is reduced to lactic acid or alcohol in the absence of oxygen and nicotinamide adenine dinuleotide+hydrogen(NADH) is oxidized . This process produces two ATP per glucose molecule.
Answer:
plate: a disk formed in the phragmoplast of a dividing plant cell that eventually forms the middle lamella of the wall between the daughter cells.
plate boundary: Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. ... Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other
earthquake: An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. ... An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground. The strain becomes so great that rocks give way by breaking and sliding along fault planes.
convirgent: In evolutionary biology, convergence pertains to an evolutionary process wherein organisms evolve structures that have similar (analogous) structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated.

Answer:
Explanation:During fertilization the embryo receives half of its genetic information from both parents. If one parent is a carrier or sickle cell their genes would be Aa little a being the recessive gene. When mixed with the other parents gene who does not have sickle cell their genes would be AA. When you make a pun net square the results would be AA,AA,Aa,and Aa. Therefore the offspring would have a 50% chance of being a carrier of sickle cell but not having the actual disease
