Answer:
As receptor, cell identity
Explanation:
In most of animal cells, there is carbohydrate layer out of cell membrane. This structure is embedded tightly with the membrane. In terms of composition, this is named glicocalyx or carbohydrate-rich layer.
Glycocalix can be glycoprotein if carbohydrate bind to protein, while glycolipid if lipid bind to its carbohydrate. Both of them provide as reseptor to communicate with another cell.
These structures also acts as cell identity. For example in blood type categorization, which determine the type of blood and antigenic traits. It also provide a sign as “self cell” and “foreign cell” in immune system. This concepts has an essential role in organ transplant compatibility.

Which observation would provide indirect evidence that supports a hypothesis that the bubbles are 02?
• A. A description of the shape of each leaf after a plant is kept under dim light
• B. A count of the bubbles produced over time by one plant under bright light
• c. A decrease in the approximate size of each leaf on plants kept in darkness
• D. An increase in bubbles on the plant when it is moved under a brighter light
SUBMIT
An increase in bubbles on the plant when it is moved under a brighter light would give indirect evidence to support the hypothesis that the bubbles are [tex]O_2[/tex].
PhotosynthesisDuring photosynthesis, green plants use their chlorophyll to absorb sunlight. This solar energy is then used to fix carbon dioxide and water into glucose while oxygen is liberated as a by-product of the reaction.
The process happens through a series of steps. Some happen in the presence of light while others happen without light. Those steps that require sunlight are said to be light-dependent while those that do not are said to be light-independent.
The overall equation of the reaction is written as follows:
[tex]6CO_2 + 6H_2O -- > C_6H_1_2O_6 + 6O_2[/tex]
Since the reaction depends on light, the brighter the light, the faster the rate of the reaction, all other factors being equal. The faster the rate of the reaction, the more bubbles of oxygen will be formed.
In other words, an increase in bubbles on the plant when it is moved under a brighter light would give indirect evidence to support the hypothesis that the bubbles on the water plant are oxygen gas.

Write an essay about why or why not: Should scientis clone the DNS of dinosaurs and bring them back to populate the earth?
DNA degrades over time. Dinosaurs went extinct about 66 million years ago, and so much time has passed that it is highly unlikely that any dinosaur DNA remains today. Dinosaur bones can survive millions of years, but dinosaur DNA almost certainly cannot.
The oldest DNA fragments found are only 800,000 years old, so cloning dinosaurs is probably impossible. True cloning also requires intact living cells and has been successful only in host animals of the same species. This also excludes mammoth clones. If you dig up a fossil today the dinosaur DNA in it would have fallen apart long ago.
So, as far as scientists know even with the best technology available today, it's impossible to make a dinosaur out of DNA.
