Answer:
Something that an antibody or T-lymphocyte binds to
Explanation:
As per the definition, antigens are the substances or molecules that are capable of inducing an immune response. When our immune system detects any unwanted substance or molecule in our body, the specific type of antibody is made against that antigenic substance and the antibody made against it binds to the antigen so that the other immune cells can recognize it and destroy it and protect us form its harmful effect. T-cell are also involved in recognizing antibodies and specific T-cell can bind to the antigen.
A population of frogs with
slightly different coloring is an example of microevolution. Microevolution is
the changes in the gene pool of a population that can be measured and observed in
short periods of time within a population. Microevolution can take place in
several ways such as gene flow, genetic drift, mutation and selection.
<span>Assume: Energy = Sunlight.
grow lamps, etc.
A is definitely correct: Plants and trees that need maximum light MUST be able to grow as tall or taller than the other plants/trees around them. Plants that are more efficient at producing food (through photosynthesis) can live in the shadows of other plants. B doesnt involve getting or using energy. C is the function of food storage. The Energy was used to make the carbohydrates up in the leaves. D This should read New Leaves on the tree... If the tree was not deciduous, the leaves would stay on the tree and continue to perform photosynthesis throughout the year - as long as there was ample light. A is definitely correct and D is probably a correct answer also. FYI - Photosynthesis takes water from the plant, CO2 from the air and Energy from the Sunlight. Chloroplasts (the Green in the green leaves and stems) combine the molecules and light energy to produce 3 byproducts: O2, H2O, and Carbohydrates (mainly sugar or C12H22O11). The carbohydrates are then transported by the plants capillary system (by means of the Phloem which flows down to the roots) to the roots where it is converted as needed to be stored as some form of sugar or starch for use later in plant growth (leaves, stems and roots).</span>
