Answer:
The two components that helps to maintain the homeostasis of the cell are 1 Buffer system 2 Membrane transport process
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside our body
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system
C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
D) Have chemical receptors for taste on their legs
Answer:
1) An origin of replication.
2) A selectable marker (e.g., a gene encoding antibiotic resistance).
Others are not necessary.
Explanation: In genetic engineering, three (3) things are responsible for manipulating nucleic acids, they are: plasmid, an origin of replication, and a selectable marker.
Answer:
All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. ... Also unlike bacteria, most viruses do cause disease, and they're quite specific about the cells they attack.
