Hello There!
A red blood cell placed in pure water would "BURST"
This is because water would move in the red blood cell and become hypotonic. It does not have enough space so thats why it bursts.
<u>Answer:</u>
Cellular respiration:

Photosynthesis:

<u>Explanation:</u>
The process of breaking down the sugar into a form of usable energy by the cell is called cellular respiration.
It can be shown by an equation as:

So the product here includes ATP which is the energy along with carbon dioxide and water.
While photosynthesis is the process where sunlight is used to convert the carbon dioxide into sugars to be used as energy.

Here the products are sugars, oxygen and water.
Answer:
A. Species that remained after the extinction were able to radiate, new adaptations arose, and these adaptations produced the diversity seen today.
Explanation:
When species went extinct they also left niches that could be occupied by "new" species; new places to live, places to be filled in the food web and different relationships to be formed. The wide availability of resources made organisms to radiate leading to a "new" diversity of shapes, sizes, and lifestyles.
B. Species that have gone extinct were able to re-evolve from the ancestors that survived the extinction. If you are extinct you are gone forever.
C. Species that remained after the extinction were unable to speciate. Therefore, the number of species on Earth today is lower than the number of species present just before either extinction. The fossil record proves that species have changed over time and the diversity has changed over the history of Earth.
D. Species that remained after the extinction represented all of the lineages that were present before the extinction event. Therefore, extinction did not change the diversity of lineages. Again, the fossil record is evidence that lineages have changed over the history of the Earth.
Peptidoglycan is present in the cell wall of gram-positive bacteria. Bacteria are safeguarded by a robust cell wall comprising peptidoglycan. The layer of peptidoglycan in the cell wall of bacteria refers to a crystal lattice composition produced from linear chains of two alternating amino sugars, that is NAM (N-acetylmuramic acid) and NAG (N-acetylglucosamine). Peptidoglycans is one of the most essential sources of D-amino acids in nature.
