Answer:
D
Explanation:
The functions of nucleic acids(DNA AND RNA) have to do with the storage and expression of genetic information. DNA encodes the information of the cell necessary to make proteins while the RNA participate in protein synthesis.
Answer:
Kinase-connected receptors or receptor tyro-sine kinases react for the most part to protein and chemical go between. A solitary trans membrane helix interfaces the extracellular restricting area to the intra-cellular space. e.g. insulin, development factors. The official of the ligand triggers the commencement of a few succession of occasions related with phosphorylation of proteins, this is called protein kinase course.
For instance, the official of development hormone to the receptor in the plasma layer causes dimerization (by the actuation of Janus kinase 2, JAK2) of the receptor (conformation change) that bring about auto-phosphorylation of tyro-sine buildups. The official of SH2-space (src homology) protein (Grb-2) to the phosphorylated tyro-sine buildups invigorates cell development through a course of protein phosphorylation.
a). RTKs are the trans-membrane receptors, which have a ligand restricting site on the extracellular area and tyro-sine authoritative on the intra-cellular space. In the event that it comes up short on the extracellular area, the ligand can't tie to the receptor site, so no cell reaction happens.
b). On the off chance that it does not have the intra-cellular space, the ligand can tie to the receptor site, the receptor can't impart signs tot eh intra-cellular area because of the absence of intra-cellular space.
Answer:
A
Explanation:
release of energy through the breakdown of glucose
Answer:
the answer is B
Explanation:
plants need carbon dioxide to be able to produce anything
Answer:
Los gases que tienen huellas de carbono son dióxido de carbono, monóxido de carbono y gases de metano, etc.
Explicación:
Los gases contaminados que contienen huellas de carbono son dióxido de carbono, monóxido de carbono y metano, etc. Estos gases tienen un efecto negativo sobre el medio ambiente porque son responsables del calentamiento global de la atmósfera y disminuyen la calidad del aire que produce muchas enfermedades nocivas. Las principales causas de la emisión de gases contaminados son las actividades humanas como la quema de combustibles fósiles y el humo que producen las industrias, etc.
