Answer:
The meaningful differences between organisms in a population are genetic. Variations in the genome of members of a population arise through mutation. Occasionally, a mutation occurs in an individual that is beneficial, that helps that organism be better able to survive and repoduce in its current environment.
Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.
Answer:
Over all growth and development cycle
Explanation:
<em>C. elegans,</em> due to its manageability, nervous system, muscle, skin gut and reproductive cycle makes it an ideal model. These nematodes are similar to human systems and lot of the research found can be applied to humans and medicine.
Apoptosis is the programmed cell death and this can be for many reasons such as repair, replace or removal of old or damaged cells. This groundbreaking research has captured the attention of scientist over the decades and many new findings are continuing to evolve.
Some phenotypes that are important in studying apoptosis are: Stress response, growth and development, tumor formation/regeneration and wound healing.
Two examples of radioisotopes that can be used are carbon-14 to determine the age of fossils. Second, we can use iodine-131 to treat thyroid disease.
