Answer:

B)

Anaerobic respiration

Explanation:

All living organisms require energy for survival. They obtain this energy via the process of cellular respiration, where they breakdown the energy in their ingested food. However, the process of cellular respiration can either be aerobic (with oxygen) or anaerobic (without oxygen).

Anaerobic respiration is carried out by organisms who do not require OXYGEN for the process. This is the case of the bacteria described in this question which survive in a puncture wound that has healed on the outer surface of the skin in an environment without oxygen present. The type of respiration carried out by this bacteria is ANAEROBIC RESPIRATION.

kolezko [41]

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:

The correct answer is -

A: Prophase  (top left)

B: Cytokinesis  (top middle)

C :Interphase  (top right)

D :Telophase  (bottom left)

E: Metaphase  (bottom middle)

F: Anaphase (bottom right)

Explanation:

A. prophse - the first stage of mitosis, in this pahse the chromatin which is DNA and proteins, condenses in nucleus.

B. Cytokinesis  - It is the physical sepration or dividion of cytoplasm of the parental cell.

C. Interphase - This phase have no change in cell except its size as it grows and enlarges itself.

D. Telophase - formation of a nuclear membrane around chromosome set to separate the genetic material from the cytoplasm.

E. Metaphase - visible chromosomes, removal of nucleus and chromosomes present in cytoplasm.

F. Anaphase - replicated chromosomes are separated and move towards opposite poles.
