Answer: The reason why stem cell research is a big field in biology or even the world is because stem cells might be able to treat degenerative conditions as well as answering questions about human development.
<u>Answer:</u>
Considering the nitrogen cycle, all organisms depend on bacteria to produce and maintain adequate nitrogen in the environment by eating the plants that contain bacteria which contain nitrogen.
Option: (B)
<u>Explanation:</u>
- Nitrogen is a main element in the nucleic acid of both RNA and DNA which is most important for all living creatures and biological molecules.
- When plants doesn’t get enough nitrogen it doesn’t produce amino acid, without amino acid plant cannot make special proteins.
- Amino acid is building block for DNA which tends to the generation of organism.
- Nitrogen fixation is a process where bacteria convert atmospheric nitrogen to usage form for plant and animals get nitrogen by eating those plants.
Answer:
option d. end capping
Explanation:
The ABP or actin binding proteins are attached with actin. The actin filaments are attached with ABP. The actin binding proteins provide large number of monomers of actin for polymerization. The ABP also help in new filament assembly. The ABP function in promoting the process of elongation. The ABP allows filament severing/depolymerization.
The end is attached with cap having the pointed or barbed ends. The barbed end gets attached with capping proteins (CP) thus blocking polymerization. So, ABP are not involved in end capping. Thus, option d is incorrect.
So the teachers ratio was 9 yellow: 6 blue, which can be simplified to 3 yellow :2 blue
Gina's ratio was 4 yellow: 3 blue
They are not the same
teacher- 3:2
Gina- 4:3
This ratio is in terms of yellow to blue
