Megan observes four cells under a microscope and makes sketches of them as shown. Identify whether the cells are prokaryotic or
posledela
I cannot found the images of the microscopy anywhere. But I can explain how you can differentiate a procaryote from a eucaryote under a microscope.

The first difference between them is the size of the cell. eucaryotes are generally much bigger than procaryotes. Procaryotes are visible only at x100 objective, but eucaryotes are visible starting from the x10 zoom.

The second difference is the presence of a nucleus in eukaryotes and the absence of it in procaryotes.

The third difference is the presence of organelles in eukaryotes and the presence of a cell wall in procaryotes (only visible at electronic microscopy).

vredina [299]

Answer: Aerobic respiration will not take place and the animal will lose large amounts of ATP.

Explanation:

Mitochondria is the powerhouse that converts product of glycolysis that occurs in the cytoplasm into energy and release carbon dioxide as a byproduct. In the presence of oxygen (aerobic), products of glycolysis such as pyruvate enters the mitochondria, joins the kreb cycle and the electron transport chain yielding a large amount of energy or ATP.

Aerobic respiration that yield large amounts of ATP strictly occus in the mitochondrial matrix whereas anearobic respiration occurs in the cytoplasm.

Answer: 31, Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground

32, Sedimentary rocks can be organized into two categories. The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals

33, Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
