For decades, science popularizers have said humans are made of stardust, and now, a new survey of 150,000 stars shows just how true the old cliché is: Humans and their galaxy have about 97 percent of the same kind of atoms, and the elements of life appear to be more prevalent toward the galaxy's center, the research found.
The crucial elements for life on Earth, often called the building blocks of life, can be abbreviated as CHNOPS: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. For the first time, astronomers have cataloged the abundance of these elements in a huge sample of stars.
Answer:
There are three types of lipids in the body, triglycerides, phospholipids and sterols.
Explanation:
Triglycerides are also known as triacylglycerols and compose 95% of fat in the foods we eat. Triglycerides are also the main fats we store in our body. When you pinch an inch around your waist, you are pinching triglycerides.
Phospholipids bring water and fat together and are called emulsifiers. Phospholipids make up cell membranes and lipid carrier molecules.
Sterols are found in tissues of animals and plants. The most well known sterol in our body is cholesterol. Cholesterol makes up bile, hormones and vitamin D.
The answer is 4. Mitochondria
D. Ingested BPA may affect the brain, behavior, and reproductive development in fetuses, infants, and children.
Explanation:
From the passage the scientific claim suggests that ingested BPA may affect the brain, behavior, and reproductive development in fetuses, infants, and children.
This scientific because no random assumption was made.
- The paragraph traces the story of BPA and how it gets ingested into human tissues and body system.
- Some scientists must first made some observation.
- Then ask the how question to see what cause some special reproductive behaviors.
- They then proceed to formulate hypothesis round their findings.
- This would then be followed suit by the analysis of their data and the interpretation given above.
