Answer:
Cretaceous
Explanation:
From what has been examined so far, there are evidence that at the end of the Cretaceous period a very large asteroid or comet stuck the Earth. The impact was where modern day Yucatan is located, and it released such an enormous energy that it managed to change the face of the Earth. The explosion itself managed to kill off pretty much everything nearby, but there was also a very hot wave that circled the whole planet. Enormous amounts of dust and ashes were released into the atmosphere that blocked the Sun, and the volcanoes all over the globe were triggered. This caused major climate and environmental changes, leading to a mass extinction, with the most noticeable victims being the dinosaurs.
The answer can be pollination or cross-pollination.
Answer:
1. Gibberellins
2. Abscisic acid
3. Cytokinins
4. Ethylene
5. Auxins
Explanation:
Hormones, generally, are chemicals produced in a specific part of an organism in order to bring about a physiological change in another part. Hormones produced by plants are classified into the following: Auxins, Gibberellins, Cytokinins, Ethylene, and Abscisic acid. They effect the following major functions in plants:
- Gibberellins: These are hormones produced by plants that stimulate stem elongation, seed germination, and flowering.
- Abscisic acid: These are hormones that regulates survival functions of a plant such as the opening and closing of stomata.
- Cytokinins: These are chemicals/hormones that helps plant cells divide.
- Ethylene: These are hormones that promotes ripening of fruit or blooming of flowers.
- Auxins: These are chemicals or hormones produced in plants that are characterized by their ability to induce cell elongation and cell division in stems.
