When Gregor Mendel crossed purple flowered pee with a white flower pea plant and all the F1 offsprings were purple due to a reason that;
- The purple color of flowers is dominant over the white color of flowers.
- The purple flower plant of the pea in the cross was also the homozygous dominant that is why all the offsprings were purple.
Answer:
Question 7:
C
Question 8:
C
Explanation:
Question 7:
If the pH number is smaller, the solution is more acidic. In turn, this means that it contains more H+ ions that OH- ions
Question 8:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution
<span>Mostly all ionic compounds dissolves in water because molecules present in the water hydrates the ions. Water is a formation of polar molecules hydrogen (partial +ve) and oxygen ( partial -ve) respectively. When a pinch of salt is poured in water, it breaks into na+ (Sodium positive) and Cl- ( chlorine negative) ions respectively and the partially positive hydrogen molecules are attracted to the chlorine anions where as the partially negative oxygen molecules are attracted to the sodium cations Then the formed bond are free to move around the water which makes it to dissolve in water.</span>
I think it’s wind. Most waves do generate by wind. Hope this helps!
Answer: Drop in turgor pressure
Explanation: Turgor pressure is caused by the amount of water maintained within the vacuole. The more pressure from water, the more it will push up against the cell wall within the stem and cause the plant to stand upright
