During this process a seed will develop. Fertilization in flowering plants happens through a process called pollination. Pollination occurs when pollen grains from the anther land on stigma, and after fertilization occurs, each ovule develop into a seed. Each seed seed contains a tiny, undeveloped plant called an embryo.

Answer:
Spring's displacement, x = -0.04 meters.
Explanation:
Let the spring's displacement be x.
Given the following data;
Mass of each shrew, m = 2.0 g to kilograms = 2/1000 = 0.002 kg
Number of shrews, n = 49
Spring constant, k = 24 N/m
We know that acceleration due to gravity, g is equal to 9.8 m/s².
To find the spring's displacement;
At equilibrium position:
Fnet = Felastic + Fg = 0
But, Felastic = -kx
Total mass, Mt = nm
Fg = -Mt = -nmg
-kx -nmg = 0
Rearranging, we have;
kx = -nmg
Making x the subject of formula, we have;
![x = \frac {-nmg}{k}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%20%7B-nmg%7D%7Bk%7D%20)
Substituting into the formula, we have;
![x = \frac {-49*0.002*9.8}{24}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%20%7B-49%2A0.002%2A9.8%7D%7B24%7D%20)
![x = \frac {-0.9604}{24}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%20%7B-0.9604%7D%7B24%7D%20)
x = -0.04 m
Therefore, the spring's displacement is -0.04 meters.
