Answer:
Acclimatization
Explanation:
Acclimatization is the change in the body of an organism in response to changes in the environment to maintain equilibrium (homeostasis). In the case of the salmon, when the environment changes from fresh to salt water and back, the chemical homeostasis would be altered if the fish didn't adjust. The adjustments in the fish gills are the response of the fish to acclimatize to the changes in the chemical environment in order to maintain homeostasis.
Answer: I think one observable adaptation of the redbud tree that makes it a member of the legume family is the shape of the fruit.
Explanation: Different species might look dissimilar but the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry
It's the small intestine that the pancreas protect
Answer:
The answer is d. 3,4,2,1,5
Explanation:
The correct sequence is:
- Antigens from a pathogen bind to antigen receptors on Lymphocytes.
- Lymphocyte specific to antigens from a pathogen become numerous.
- Lymphocytes secrete antibodies
- Pathogen is destroyed.
- Only memory cells remain.
Adaptive Immune System/Acquired Immunity:
Adaptive immune system involves the part of immune system that is contains specific and highly specialized cells to target specific pathogens. Acquired immunity involves antigen specific antibodies that bind and mark a specific pathogen. This pathogen is then cytotoxically destroyed by specific effector cells of the immune system. Acquired immunity is also characterized by the production of memory cells at the time of mass production of antigen specific antibodies. These memory cells remain long after the pathogen has been destroyed to protect against consequent attacks from the same pathogen.
IN between the G1 and the G2 phase of the cell cycle the cell's DNA replicates its DNA. The number of chromosomes stays the same, but the amount of DNA molecules duplicates.
Therefore, our cell with 6 chromosomes in the G2 phase has 6 chromosomes and 12 DNA molecules.
