Answer:
Answer : Scientific theories are rigorously supported by numerous studies, and are hypotheses that, even up till date, have never been disproved.
Explanation:
Scientific theory can be explained as a theory that was highly supported by facts. This means that , it is continuously or repeatedly confirmed by observation and experiment by scientists.
Evolution can be described as changes that occur in the heritable characters over a period of time. This usually occurs through natural selection.
In this case, evolution is known to be a scientific theory, because it involved careful observations and confirming experiments by scientists.
Answer:
Both water and oil are not minerals because they are liquids.
Explanation:
Osmosis is a vital function to the growth and stability of plant life. Without osmosis, photosynthesis would never occur and plants would wilt and die. Osmosis distributes water through selectively permeable membranes to maintain this proper volume and pressure of all plant cells.
Answer:
In the earliest stage of liver disease, the liver becomes inflamed. The patient may not even be aware of the inflammation but left untreated, the inflammation will begin to scar, compromising the function of the liver. Liver inflammation and scarring (also known as a fibrosis) can be reversed with proper treatment. Without proper treatment, the damaged liver will progress to cirrhosis.
Common symptoms of cirrhosis include:
Loss of appetite
Weakness
Fatigue
Nausea/Vomiting
Abdominal pain/bloating
Itching
Once a patient is diagnosed with cirrhosis, it can no longer be cured. The focus of treatment changes to stopping the condition from worsening and slowing the disease progression. If the illness worsens to the point of end-stage liver disease, the patient will experience symptoms that include:
Jaundice – yellowing of the skin and eyes caused when the liver is not able to rid the body of bilirubin.
Increased risk of internal bleeding – patients may have black stool from internal bleeding or they may vomit blood.
Buildup of fluid in the abdomen – caused by high pressure in the liver’s veins, fluid will leak into the abdomen and legs.
Confusion – reduced brain function due to high levels of toxic substances in the body that the compromised liver can no longer process.
Interphase + MITOSIS (PMATC)
In Interphase, there’s DNA replication taking place, of every organelle, it’s under extremely high energy (REMEMBER INTERPHASE IS NOT APART OF MITOSIS, IT HAPPENS BEFORE IT) In prophase, spindle fibres start to appear, membrane around nucleus dissapears. In metaphase, chromosomes line up in the middle of the cell, along with their copies. In anaphase, they are pulled to either end of the cell on spindle fibres. In telophase, cell walls form around each pair or chromosomes. In cytokinesis, the cell membrane eventually divides them into two genetically identical daughter cells.
