Answer:
B. Genetic engineering of a virus to create a biological weapon.
C.Use of genetic modification to produce laboratory mice with D.Alzheimer's disease.
E.Use of genetic modification to produce a superior race of humans
Explanation: Biotechnology is the use of biology to solve various problems.
Modern biotechnology has provide various technologies to fight debilitating and rare disease, increase food production and the use less and cleaner energy.
The use of Genetically modified organism(GMO)produced through genetic engineering is one of the major biotechnology that is used in this age or generation. GMO's contains genes that are artificially engineered into them that are beneficiary.
Answer:
C. Joining of self-replication molecules into protocells.
Explanation:
For the origin of life, at least three conditions are needed.
- there must have been a supply of replicators, that is, self-replicating molecules.
- copying of these replicators must have been subject to error through mutation.
- the system of replicators must have required a continuous supply of free energy and partial isolation from the general environment.
The radiation received from the sun on the early earth must have fulfilled the requirement of mutation. The mutation is necessary for bringing variation in the genetic material thus driving evolution. To protect the self-replicating molecules from the external environment and to keep them together, the molecules must have been enclosed in a membrane barrier, which should be selectively semipermeable, to facilitate the exchange of molecules.
Answer:
the alveoli are made of thin squamous (type I) alveolar cells which allows for the quick diffusion carbon dioxide and oxygen.
Explanation:
Diffusion of gases takes place between the alveolar cavity and the blood in the capillaries. Oxygen being more concentrated in the alveoli diffuses across the epithelium of the alveoli and the endothelium of the capillaries into the blood. The epithelial walls of the alveoli are moist and thin thus enhancing the diffusion.
actually the answer is D. I put a and got it wrong then it showed me the answer.
Answer:
The correct answer is "Thylakoid Membrane".
Explanation:
Photosynthesis results in free electrons due to the energy from sunlight so there is also photon movement. In plants this happens in the chloroplasts. Chemiosmosis defines the movement of ions (hydrogen ions H+) which happens towards the thylakoid membrane from the stroma. I hope this answer helps.
