Gymnosperms are no longer restricted to moist environments, as are ferns and mosses because they have evolved to produce non-flagellated pollens that do not require water or moisture to reach the egg whereas ferns and mosses have flagellated sperm that needs moisture to swim towards the egg.
Another major evolutionary adaption in gymnosperms is the production of seeds instead of spores since seeds contain their own nutrition in the form of endosperm, seeds can travel large distances through wind or animals and can germinate when they find suitable conditions. Seeds can remain dormant for several years whereas spores have a shorter lifespan.

Answer:
The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
The most reason for an organism having lipids in its body is to provide energy to the body. The fat molecules in the lipids can supply more energy gram than carbohydrate molecules. The fat molecules are composed of carbon (C), hydrogen (H), and oxygen (O) atoms. I hope this will help!! Have a great day.
Grounding and insulation will be the two most recognized means of preventing injury during an electrical equipment operation. The workers should always place a non-conductive material like plastic around the conductor of electricity. When grounding, there needs to be a direct connection to either a cold water pipe or even metal. Without doing either grounding or insulation, there is a chance of burns, shocks, fire, and in extreme cases death.
Answer:
5.) While it appears in a balanced ecosystem that nothing is changing, there is indeed either subtle or gradual changes that constantly happens through natural succession.
6.) Predator-prey relationships achieve a state of balance:
a.) Prey- They are food for predatory animals and help them thrive with nutrients that they possess.
b.) Predator- They help reduce overpopulation for prey
