Producers make their own food through the process called photosynthesis, which uses water and sunlight to produce glucose and oxygen as a byproduct. It uses glucose to power its cells.
Plants grow through the cracks and animals dig in the soil, further breaking apart and dislodging structures. Chemical processes, like the oxidation of iron, cause unsightly rust. Carbonic acid, a result of carbon dioxide mixing with water, dissolves limestone. Acid rain also wears down stone.
Answer:
Cell counter inverted microscope and liquid nitrogen storage incubator are the technologies used in the cell culture.
Explanation:
Cell culture needs control environment for the production of cells in order to avoid contamination from other microbes. For this reason, liquid nitrogen storage incubator is used which decreases the temperature in order to slow down the process of cell division and other cellular processes and also provide safety from contamination. Cell counter inverted microscope is used to see the growth of the cells at the bottom of storage tank.
Answer:
D) all are correct statements.
Answer:
A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.
Explanation:
The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.
The F1 cross would therefore be Gg x Gg. See attached punnet square.
The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1
Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)
