Answer:
These agents are known as teratogens.
Explanation:
Teratogens impair or cause abnormal development and growth of the embryos or fetuses exposed to them. During prenatal development, the embryonic stage is the most susceptible to teratogens because at this time there is formation of major organs and limb buds. Birth defects are a common sign of such exposure.
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.
Answer:
Heterotrophs
Explanation:
Heterotrophs are organisms that are not able to form their own source of energy and are dependent on others to gain energy. Most of the algae are autotrophs which uses light energy to make organic energy source.
Some algae are heterotrophs that do not require sunlight and pigments as they do not make their food on their own and utilize sugars manufactured by other plants and algae.
They are also called colorless algae as they do not possess pigments. These heterotrophic algae are consumers, not producers. Therefore the correct answer is heterotrophs.
