Cow's four chambers

Cow's have 4 chambers to help them in digestion of the food they intake. The chambers are rumen, reticulum, omasum, and abomasum.

Rumen and Reticulum- rumen is the first chamber where the food goes into after it's taken. This chamber ferments the food that is mixed with saliva.  Both have the same objective through a different function, this is often call the reticulorumen. The food that is mixed with saliva gets turned into solid clumps to form bolus. The bolus is then regurgitated (bringing the food back to the mouth) for breaking down the food using saliva. Reticulum also has another job, cow's sometimes eat foreign materials such as nails, plastic, and other indigestible objects, this makes the cow sick so the reticulum has hexagonal honeycombed type of layer to trap the objects.

Omasum- is the 3 chamber. This helps water and many of the inorganic mineral elements to be absorbed into the blood stream. It also absorbs some of the nutrients produced in the rumen such as the Volatile Fatty Acid.

 Abomasum- is also known as the true stomach. This compartment mostly behaves like a humans stomach. Abomasum produces acids such HCL and pepsin to break down protein that cannot be broken down in other compartments.Then the food is moved to the small intestine

Vegetable Battery

Image
The energy for the battery comes from the chemical change in the zinc (or other metal) when it dissolves into the acid. The energy does not come from the lemon or potato. The zinc is oxidized inside the lemon, exchanging some of its electrons with the acid in order to reach a lower energy state, and the energy released provides the power. In current practice, zinc is produced by electrowinning of zinc sulfate reduction of zinc with carbon, which requires an energy input. The energy produced in the lemon battery comes from reversing this reaction, recovering some of the energy input during the zinc production.

Cell Cycle part 2

Image
Now the cell should have double the amount DNA after interphase. The next phase is m-phase. The m-phase consists of mitosis (separation of 1 cell nucleus to 2 nuclei) and cytokinesis (cytoplasmic division or whole cell division). There are 4 steps in mitosis. To help understand this concept, I will explain the structure of a chromosome. A chromosome is formed during mitosis to help in nuclear division. A chromosome has two sides, each side is a copy of the other(interphase), therefore, each side separates into its own nucleus so the new cell has an exact copy of the parent cell's DNA. The first phase is called prophase. During prophase, the chromosomes become visible from chromatin and the nucleolus disappears. The next phase is called metaphase. Here, the chromosomes line up in the center and fibers called spindle fiber attach to the chromosomes centromere from both sides. The next step, anaphase, the spindle fibers pull on the chromosomes where each copy is separated to either s

How does graphite conduct electricity ?

Image
Graphite can conduct electricity due to the vast electron delocalization ( delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or one covalent bond)  within the carbon layers (a phenomenon called aromaticity ). These valence electrons are free to move, so are able to conduct electricity. However, the electricity is primarily conducted within the plane of the layers. The conductive properties of powdered graphite allowed its use as a semiconductor substitute in early carbon microphones.
