The answer bilaterally symmetrical. Bilateral symmetry means that an object is equally divided in half along its central axis.
Answer:
A. Bacterial species use a limited number of nutrient sources.
Explanation:
There are two classes of nutrients that are indispensable to bacteria: macronutrients (carbon, oxygen, nitrogen, sulfur, phosphorus and hydrogen) and micronutrients (iron, zinc, manganese, calcium, potassium, sodium, copper, chlorine, cobalt, molybdenum, selenium, magnesium, among many others). But it takes more than the nutrients for them to feed, it takes the metabolism, because it is through it that they transform what they have into food.
The absorption of nutrients to carry out the metabolism only occurs because there are growth factors (environmental) that influence the development of the bacteria. Some examples of these factors are: light, temperature, pH, oxygen and osmotic pressure. Each organism has an optimal growth temperature, or a favorable pH to successfully carry out its metabolism. This will vary from species to species.
Gibberellins break seed dormancy and promotes germination. However abscisic acid is the only hormone known to induce and maintain seed dormancy
