3. Iodide ion (I−) reacts with hydrogen peroxide (H2O2) with a rate constant of 0.0133 M−1s−1 at 25°C. The values for x and y in the rate law equation are both egual to 1. What concentration of iodide ion should be added to 1.5 M H2O2 to achieve a rate of reaction equal to 6.0 × 10−4 M/s?

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set

the answer is definitely a
