Answer:
1. A. Pseudomonas and E. coli
2. B. Red without black center
3. B. Salmon/orange
Explanation:
Pseudomonas is referred to as an oxidase positive bacteria while E. Coli is an oxidase negative bacteria. The use of the oxidase test will be helpful in the differentiation of the two Bacteria according to their oxidase activity/properties.
Colonies of Red without black center color is what is expected on HE agar if shigellosis is suspected.
Colonies of Salmon/Orange color is what is expected on HE agar if Enterococcus sp. is suspected.
The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
<h3>
How do materials move within the earth?</h3>
The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.
So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

All cells require ATP for energy.
This one’s a little tricky. I think your 2 best options are B and D
Not sure if you want to represent the particles moving but not making contact, which would be B or the particles moving and keeping contact which would be D.
Hope this helps a little

<span>Meat tenderizers contain proteases, which are enzymes that break down proteins. In meat, they break down the proteins that make up muscle, softening the meat in the process.
In DNA extraction, they break down the protein core, called a histone, that the DNA is supercoiled around. It's the supercoiling that allows a few meters worth of DNA to be compacted into a microscopic structure, and it also plays a role in gene regulation.
To a lesser extent, the proteases in the tenderizer can break down DNase enzymes (since enzymes are proteins too), which chop up DNA (to protect the cell from some viruses). Normally, the DNase is kept separate from the cell's DNA, but when you add detergent to the cells and break apart the membranes, all of the components can mix together and lead to unintended reactions.
When you break down the histone proteins, the DNA uncoils and stretches out, allowing you to see it and wind it around a stick (if your extraction protocol includes that step).</span><span>
