Answer:
The volume of a pair of dice could be gotten by measuring the
sides and calculating it via length/width/height. A second manner
would be displacement, where the dice are placed in a liquid with a
known density, and the mass of the liquid displaced is used to
determine volume.
A mutation can occur in DNA too
Answer: Option B) Lipids generally don't dissolve in water.
Explanation:
All lipids are small biomolecules that are insoluble in water but dissolve readily in nonpolar organic solvents, and contain fatty acids, sterols. So, not all lipids are made of fatty acids and glycerol, and the chemical properties of each lipids depends on their composition.
Thus, all lipids share the characteristics of not dissolving in water.
Mutations can be somatic or inherited. Somatic mutations are mutations that occur in a single body cell, so only tissues derived from mutated cell are affected. Somatic mutations are not inherited. On the other hand, inherited or germline mutations occur in gametes (egg cells and sperm cells) and are passed onto offspring. As a result of these kind of mutations each cell in the organism is affected.
Somatic mutations: BRAF and KRAS gene.
Inherited mutations: FRG2 and BRCA1 gene.
Answer:
approximately 2.3 parts per million (ppm) per year
Explanation:
In 2019, the global amount of atmospheric carbon dioxide (CO2) has been estimated at approximately 410 parts per million (ppm). These levels are higher than at any time in the last 800,000 years, and it has been estimated that in 2025 the CO2 levels will be higher than at any time in the last 3.3 million years. In 2018, there has been an increase of approx. 2.5 ppm, the same increase observed between 2017 and 2018. Moreover, the average increase of the CO2 levels in the atmosphere between 2009 and 2018 was 2.3 ppm each year.
