Answer:
The correct answer is - d. gradualism.
Explanation:
Gradualism is a model of evolution that explains that the smaller variation in an individual organism that is occurring over a period of the time is to the betterment of the organism in their environment.
These changes or variations allow them to thrive and survive with a slow successive change in an evolutionary line or the whole population. It is a consistent process.
Thus, the correct answer is - D. gradualism.
There are three types of hazards
- physical such as knives, filet bone
- chemical such as cleaner, chlorine (chemical substances)
- biological such as bacteria, mold (live organisms)
Because filet bone is a physical hazard the answer is D (filet bone)
Photosynthesis in algae cells
Ecosystems were able to maintain themselves by cycling the
nutrients and energy obtained from external sources. The flow of energy through
a food chain is known as energy flow. At tropical level, solar energy is used by the primary producers to produce organic plants materials through photosynthesis.
Answer: population increases by 15
Explanation:
The population growth will be calculated by adding the Natural Increase in population plus the Net In-Migration. This will be:
Natural increase = Birth - Death rate
= 35 - 7
= 28
Net-In-Migration = Immigration - Emigration
= 4 - 17
= -13
Therefore, population growth will be:
= 28 - 13
= 15
Therefore, population increases by 15
