Answer:
transportation
Explanation:
Transportation (28.2 percent of 2018 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions.

<h3><u>Answer;</u></h3>
Whereas segregational petites exhibited Mendelian inheritance, both neutral and suppressive petites followed non-Mendelian patterns that were consistent with the involvement of an extranuclear agent
<h3><u>Explanation</u>;</h3>
- Mutations that yield defective mitochondria are expected to make cells grow much more slowly. These mutants were called petites to describe their small colonies compared to large wild type colonies.
- Petite mutants could not grow when cells had an energy source requiring only metabolic activity of mitochondria - needed sugar as well which is part of glycolytic pathway.
- Segregational petites, segregated in mendelian manner during meiosis. mutations cause defects in genes in cell nucleus encode proteins necessary for mitochondrial function.
- Vegetative petite mutants do not segregate in mendelian manner; two types: neutral and suppressive; carry mutations in mitochondrial genome itself; when two yeast cells are mated, daughter cells inherit mitochondria from both parents.
- Neutral petites lack most of their mitochondrial DNA; when mated with wildtype, the wildtype give their mitochondria so all cells display a normal phenotype.

The correct answer is: D, a decreased number of oxygen-rich mitochondria.
Radioactive dating can determine the age of minerals and fossils in each layer of rock.
Explanation:
Radioactive dating is the most commonly used geological method to determine the age of rocks and fossils layered in the layers of rock on the basis of their natural radioactive decaying.
With the help of the known rate of radioactive decay of isotopes, different types of radiometric dating are done depending upon the material found in the rock layers, like uranium-lead dating or potassium-argon dating.
Radiocarbon dating helps to record organic content in rocks like bones, shells, etc. Age of fossils sediment over sedimentary rocks is determined by combining with the bracketing method.
