Drastic change in pH or temperature because the enzyme reaction may become denatured.
Answer:
B
Explanation:
as it clearly shows on the graph
Answer:
let the three parts be
5x + 3x + 4x = 250
so on adding
12x = 250
x = 20
so it will be divided into three parts as
5 × 20 = 100
3×20= 60
4×20 = 80
Explanation:
Cell walls are rigid which gives plants their shape. Animals have only cell membranes which allows animals to be flexible as animals are moving organisms. Plants, on the other hand, are sturdy and upright and are sessile organisms. Cell walls allow plants to grow upright as high as their maximum height and to be sturdy enough to survive harsh environments.
By moving substances across membranes, transport proteins make everything from nerve impulses to cellular metabolism possible. Without transport proteins, for example, the sodium-potassium gradient that allows our nerves to fire would not exist.
