A Directly, more
I just answered this question on USATEST PREP and got it right.
Fertilization generally occurs in the fallopian tube.
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
- Half-life of the radioactive atom (t1/2): 3,500 years
- Parent-daughter ratio ([A]/[A]₀): 1:127 (1/127)
Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
The larger vacuole in the plant helps the structure of the plant more. An example would be when you see a not watered plant and it looks droopy. It's because the vacuole has no water or waste in it to help with the structure. Plus, the vacuole is able to contain more in a plant cell. This is needed because animals can go get water or food when they need it, but plants are stationary and they have to use what they have stored.
Answer:
The stem is normally divided into nodes and inter nodes.
2. Lateral buds and leaves grow out of stem at intervals called nodes.
