Answer:
(E) Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase)
Explanation:
Glyocolysis is break down of glucose into pyruvate.
Isomerization:The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P). This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI). As the name of the enzyme suggests, this reaction involves an isomerization reaction.
Yeast mutant lacking phopshoglucose isomerase unable to performed this step and that's why it unable to grow in media containing glucose while in fructose break down this step is not required so it is able to grow in media containing fructose.
Deletion of phosphoglucose isomerase, prevents growth on glucose; therefore, phosphoglucose isomerase mutant is able to grown in a fructose medium.
Answer:
Female gametes are called eggs. In human males, for example, the process that produces mature sperm cells is called spermatogenesis. ... In human females, the process that produces mature eggs is called oogenesis. Just one egg is produced from the four haploid cells that result from meiosis
Explanation:
It is choice B.
Haploid cells contain one copy of genetic information. (ex sperm, egg)
Diploid cells contain two copies of the genetic information. (ex muscle, bone brain, eye, etc.)
Kinetic Energy is a starter energy
The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.
Hope this helps!
