Answer:
Oxygen and glucose are both reactants in the <u>Process</u> of cellular respiration.
ATP is the main Product formed in cellular respiration, and waste products include carbon dioxide and water.
Hope this helps!!
Answer:
Protein synthesis in rough endoplasmic reticulum (RER) and packaging in smooth endoplasmic reticulum (SER)
Explanation:
Intracellular Protein Transport:
- After transcription in the nucleus, the mRNA is translocated from the nucleus to the ribosomes attached to the rough endoplasmic reticulum (RER). The RER is the site of the biosynthesis of proteins.
- The process of translation of mRNA sequence into amino acid sequence takes place in the RER.
- The newly synthesized protein is then packaged into vesicles in the SER and transported to the Golgi complex.
- The Golgi complex is the cell's packaging department. It packages proteins into transport vesicles for intra and extracellular protein transport.
A. He should add shells that are different colors, but the same size and type, to the tank and observe which shells the hermit crabs choose.
Durning an experiment you need to keep everything the same but only change the certain things based on your theory.
Such as how the student wanted to see if the color attracted the crab. If he had changed the size and type of the shell then the crab would have chosen the bigger one as they tend to grow into larger shells.
Answer:
B) Nitrogen-fixing bacteria and lightning
Explanation:
Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.
Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.
As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.
The lightning breaks nitrogen molecules and allow it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.
Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
