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 is e hope this helps
Answer:
Glucose can used as a substrate and broken down in plant cells by the process of respiration. The chemical energy released by respiration can be used by the plant for cellular activities such as protein synthesis or cell division.
Answer:
primary; counter; Gram-positive; Gram-negative
Explanation:
The illustration is about the <u>Gram-staining procedure.</u>
<em>The procedure is used to distinguish between the bacteria that have a thick cell wall capable of retaining the color of a dye (Gram-positive) or otherwise (Gram-negative). </em>
A smear of the bacterium to be tested is heat-fixed to a clean glass slide after which a suitable primary stain is added, allowed to stay for a few seconds, and rinsed. A mordant is then added, rinsed before a counter-stain is added, and also rinsed. The slide is then allowed to drain off water and then viewed under the microscope using the oil immersion. Gram-positive bacteria will appear blue or purple, taking up the color of the stain while Gram-negative bacteria will appear red under the microscope.
