Answer:
Linckia laevigata (sometimes called the "blue Linckia" or blue star) is a species of sea star in the shallow waters of tropical Indo-Pacific.
...
The answer would be cell membrane
Answer:
all of the above
Explanation:
When the human genome was sequenced, one of the first information generated was related to the structure of the genetic material. For example, it has been found that there are long repeated sequences in different parts of the DNA or regulatory parts of its functioning in other parts of the genetic material itself.
When determining the order of nucleotides of a living being and comparing it with others of the same species, we find some regions that accumulate more differences than others, that is, are more diverse than others. Very similar sequences, that is, conserved in all living beings of the same species, can determine essential characteristics of these organisms. These essential characteristics can be very important for many different sectors and improve the lives of humanity in unimaginable ways.
The discoveries made through the complete sequencing of a genome can cause immense improvements in the fields of medicine, agriculture, biofuels and many other fields.
Trees remove some of this carbon dioxide from the air through photosynthesis and store that carbon in their tissues and in the soil. Deforestation reduces the removal component of this cycle, further increasing the carbon dioxide in the air. This results in an increase in temperature, an effect known as global warming.
Answer:
Presence of specific antigen receptors on the surface of Immunocompetent B and T cells make them to generate immune response against specific antigens only.
Explanation:
The cellular and antibody-mediated immune responses are specific in nature. This means these immune responses are generated for particular foreign molecules or antigens only. These immune responses include B and T lymphocytes. Before T cells leave the thymus or B cells leave the red bone marrow, they develop immunocompetence. Immunocompetence is the ability to carry out adaptive immune responses. During this process. B cells and T cells make distinctive proteins and insert them into their plasma membranes. Some of these proteins function as antigen receptors capable of recognizing specific antigens. This is why the B and T cell-mediated third line of defense are specific in nature.
For example, antibody-mediated immune responses generate the memory cells for most previously encountered antigens to ensure the generation of more rapid and vigorous response during any further encounter with the same antigen.
