Answer:
1.b.) the role that an organism plays in the environment
2. d.) marshes and ponds
3.d.) both positive and negative
Explanation:
Answer: The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. Folded proteins are stabilized by thousands of non covalent bonds between amino acids.
Explanation:
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.
Answer:
most eukaryotic cells that are not involved in the production of gametes undergo mitosis. These cells, known as somatic cells, are important to the survival of eukaryotic organisms, and it is essential that somatic parent and daughter cells do not vary from one another.
