Answer:
Tissues in organs are precisely arranged so that they can work in harmony in performing organ functions. This is similar to an orchestra that contains various musical instruments, each of which is located in a precise place and contributes exactly at the right time to create harmony. Like musical instruments that are mixed and matched in various types of musical groups, tissues and cells also are present in several different organs and contribute their part to the function of the organ and the maintenance of homeostasis.
1. Development of eukaryotic cells
2. Free oxygen in the atmosphere
3. Development of prokaryotic cells
4. Sexual reproduction
The answer is all enzymes have the same shape as their substrates.
The enzyme (which is basically a protein) does not have the same structure as its substrate, but has a structural cavity that allows the substrate to be recognized by the enzyme. So there is a correlation between structure and activity, and to maintain its structure, it needs a particular environment (pH, temperature ...).
Answer:
I) Presence or absence of nuclear envelope
II) Presence or absence of membrane-bounded organelles
Explanation:
Unlike eukaryotic cells, prokaryotic cells lack nuclear membrane and membrane-bound organelles.
As a result, neither mitosis nor meiosis occur in a Prokaryotic cell.
Examples of organisms with Prokaryotic cell are bacteria, cyanobacteria
Examples of organisms with eukaryotic cells are green plants, fruitfly etc
Genetic engineering has been used to produce a type of insulin, very similar to our ... of useful applications, including scientific research, agriculture and technology.
