<span>Although it is not mentioned the location, I found the exercise on the internet with the following options:
A)weathering and erosion of park pathways
B)deterioration of the man-made structures in the park
C)pattern and timing of leaf loss in the shade trees
D)exposure of rocks and minerals found in the soil
The only effect, out of this options, that would be studied by biologists is the "pattern and timing of leaf loss in the shade trees". This is the only effect related to life, which is the subject of biology - living organisms and their mechanisms. Leaf loss is a process undergone by many trees as colder seasons, or dry seasons in the case of trees in tropical forests, approach.</span>

Answer:
i think its A but i'm not sure.
After ovulation, the corpus luteum releases progesterone and estrogen to prepare the endometrium for implantation.
What is ovulation?
Ovulation is the process in which a mature egg is released from the ovary. After it's released, the egg moves down the fallopian tube and stays there for 12 to 24 hours, where it can be fertilized.
Sperm can live inside the female reproductive tract as long as five days after sexual intercourse under the right conditions.
Your chance of getting pregnant is highest when live sperm are present in the fallopian tubes during ovulation.
In an average 28-day menstrual cycle, ovulation typically occurs about 14 days before the start of the next menstrual period.
However, each person's cycle length may be different, and the time between ovulation and the start of the next menstrual period may vary.
