Answer:
animals are the only organisms that compete for resources
Explanation:
this is due to the fact that plants take up resources passively, a method which doesn't require them to waste any energy, however in the case of resources, is not very effective. suppose there was a bit of water scarcity in your area, and a plant and you both need water for survival. obviously, the plant cant possibly do anything to receive these resources, as it is just a plant. its survival is based merely on the chance that you pour water into it. this is not the case for animals, which, like us, actively collect and gather resources, and use them to our advantage. therefore, animals are the only animals that compete for resources
During the initial exposure to the allergen, contact is made with B cells, these B cells differentiate and produce IgE antibody. The IgE antibodies which works against the allergens are released into the blood stream where they binds to Fc receptors which are located on mast cells and basophils. Now, the mast cells has become sensitized and they will wait patiently for the second exposure. When contact with the allergen is made the second time, the allergen becomes attached to the IgE present on the mast cells and this result in degranulation which trigger a lot of allergic responses.
The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.
The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:
1. Active repressor, active activator,
2. Active repressor, inactive activator
3. Inactive repressor, active activator
4. Inactive repressor, inactive activator
