A scientist should revise their experimental methods if they find that the method they are using does not get them to the outcome they expect and along the way in an experiment notices it has many flaws. They should change if necessary because a good scientific method maximizes results and leads to discovery. Hope this helps!
Answer: Lysosomes.
Lysosomes are the specialized membrane-bound cell organelles present in almost all eukaryotic cells. The lysosomal membrane keeps the acidic (pH 5) compartment of lysosomes segregated from the cytoplasm. Lysosomes play a crucial role in the degradation of waste material and debris inside the cell.
This is accomplished by the action of hydrolytic enzymes also called as acid hydrolases. These enzymes are only active in the acidic medium which is maintained in the lysosomes by proton pumps.
Lysosomes are also called as 'suicide bags' as they clear off the waste material.
No because Chiang did not experience with what happened
Answer:
The phenomenon in which osteoclast results in the degradation of the old bones and encourages the generation of novel bones by the assistance of osteoblasts is termed as bone remodeling. The remodeling of bones takes place throughout life, that is, whenever it is required. Some of the elements that monitor the process of bone remodeling are the concentration of serum vitamin D, serum level of calcium, and the level of calcitonin and growth hormone in the blood.
Thus, whenever the bone gets degrade or becomes useless it gets replaced by the process of bone remodeling. Hence, the hypothesis of 'use it' here signifies the usage of bones or else they will get useless or get degrade.
In the process of bone remodeling formation of more dense bones takes place due to the renewal of the destructed bones. This results in the presence of both the damaged bones and the newly formed bones at the same time, hence, it can be concluded that more bones are present at the time of bone remodeling.
Answer:
By manipulating DNA, genetic engineers can produce:
- Medicines (Examples Insulins and Vaccines etc)
- High Yielding Crops. These may come with certain qualities such as disease resistance, longer shelf life, and if they are fruits may be much bigger than organically grown species due to their high nutrient conversion rates.
- Genetically Modified Animals. These may be pets or commercial animals. A cow may be genetically engineered to produce more milk or more beef or both. Just like plants, they can be modified to have quick yield and high feed conversion rates.
- Industrial Use Bacterial. Some bacterial can be modified for use in the production of biofuels, removing oil spills from water bodies or land masses, carbon and other toxic waste.
Cheers!
