8. Why does Australia have so many genetically distinct organisms?
Answer:
Australia has so many genetically distinct organisms because it has been separated from other bodies of land for a very long time. This has given species in Australia a long time to evolve independently from species in other areas of the world.
Which two animals use echolocation? bats and humans bats and dolphins dolphins and humans dolphins and butterflies.
The two animals which use echolocation are bats and dolphins.
Both hunt their prey by articulating high-pitched sounds and listening for the echoes.
What is echolocation?
Echolocation is a method used by bats, dolphins and other animals to select the location of objects using reflected sound. This allows the animals to move around in pitch darkness, so they can guide, hunt, identify friends and enemies, and avoid obstacles.
Thus, bats and dolphins are two animals that use echolocation.

Which protist group produces much of the oxygen on earth?.
27.
Scientists believe that Earth's early atmosphere
changed in composition as a result of
A. the appearance of oxygen-producing organisms
B.
the drifting of the continents
C.
the changes in Earth's magnetic field
D.
a transfer of gases from the Sun
Answer:
The answer is A
Explanation:
The appearance of oxygen-producing organisms.
The appearance of free oxygen in Earth's atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing oxygen that was used by multicellular forms as early as 2.3 billion years ago.What are cyanobacteria?Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.Cyanobacteria are responsible for the Earth's transition from a carbon dioxide-rich atmosphere to the present relatively oxygen rich atmosphere as a consequence of oxygenic photosynthesis.To know more about multicellular here

WHICH LAYER OF THE SUN HAS THE DENSEST MATERIAL?
Answer:
The sun is a star, this means the sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

What is DNA like in a city?
The structures of five of the compounds of glycolysis are given. Arrange the compounds in order from the start of glycolysis to the end of glycolysis
Through the glycolysis process, the glucose molecule turns into pyruvate. The correct order of structures is Glucose/Fructose-1,6-biphosphate/Glyceraldehyde 3-phosphate/1,3-diphosphate glycerate/Pyruvate.
What is glycolisis?Glycolysis is the process through which the cell partially decomposes glucose and turns it into pyruvate.
It is about a series of enzymatic reactions that take place in the cytosol and do need no oxygen to occur. So it occurs in aerobic and anaerobic respiration.
It can be divided into two phases:
1st phase produces two 3-C molecules. This step needs the energy of two ATP molecules.2nd phase produces pyruvate, two ATP, and one NADH from each 3-C molecule.To sum up, glycolysis transforms one glucose molecule (6-C) into two pyruvate molecules (3-C), four ATP, and two NADH. Since it also consumes two ATP molecules, the net product is two ATP.
Steps
1) Glucose phosphorylation by hexokinase. A phosphate group is driven from ATP to glucose, turning it into glucose-6-phosphate -G6P-
Glucose + ATP ⇔ Glucose-6-phosphate + ADP
2) Glucose-6-phosphate isomerization. The enzyme glucose-6-phosphate isomerase turns glucose-6-phosphate into fructose-6-phosphate
Glucose-6-phosphate ⇔ fructose-6-phosphate
3) Fructose-6-phosphate turns into Fructose-1,6-biphosphate. The enzyme phosphofructokinase-1 phosphorylates Fructose-6-phosphate, providing a phosphate group from ATP to the Fructose-6-phosphate molecule.
Fructose-6-phosphate + ATP ⇒ Fructose-1,6-biphosphate + ADP
4) Aldolase enzyme divides Fructose-1,6-biphosphate into phosphate dihydroxyacetone (3-C molecule) and 3-phosphate glyceraldehyde (3-C molecule).
Fructose-1,6-biphosphate ⇔ phosphate dihydroxiacetone + 3-phosphate glyceraldehide
5) Phosphate dihydroxyacetone Isomerization into glyceraldehyde 3 phosphate -G3P- by triose phosphate isomerase.
phosphate dihydroxyacetone ⇒ glyceraldehyde 3 phosphate
6) Glyceraldehyde 3-phosphate oxydation by G-3-P dehydrogenase (GAPDH or GAP). The enzyme adds a phosphate into C-1 of the molecule, turning it into 1,3-diphosphate glycerate. To do it, the enzyme reduces an NAD+ group and turns it into NADH and an H ion.
gliceraldehide 3 phosphate + NAD⁺ + P ⇒ 1,3-diphospho glycerate + NADPH + H⁺
7) 1,3-diphosphate glycerate loses a phosphate group and turns into 3-phosphoglycerate.
1,3-diphospho glycerate + ADP ⇒ 3-phosphoglycerate + ATP
8) 3-phosphoglycerate isomerization, turning it into 2-phosphoglycerate by phosphoglycerate mutase.
3-phosphoglycerate ⇒ 2-phosphoglycerate
9) Phosphoenolpyruvate production. A double bond is formed at carbon 2 where the phosphate group was attached. A water molecule is released (hydrogen of carbon 2 and the OH- group of carbon 3) from the 2-phosphoglycerate.
2-phosphoglycerate ⇒ Phosphoenolpyruvate + H₂O
10) Pyruvate dephosphorylation and ATP formation by pyruvate kinase.
Phosphoenolpyruvate + ADP ⇒ Pyruvate + ATP

The correct order of the structures from the start of glycolysis to the end of glycolysis is Glucose → Fructose-1,6-biphosphate → Glyceraldehyde 3-phosphate → 1,3-diphosphate glycerate → Pyruvate.
What do you mean by Glycolysis?Glycolysis may be defined as a process in which one molecule of glucose is partially oxidized into the two molecules of pyruvate in a series of 10 enzyme-catalyzed reactions.
The first phase of glycolysis converts a 6-carbon molecule to two 3-carbon molecules with the help of ATP. The second phase is the payoff phase where a 3-carbon molecule may transform into the same carbon molecule known as Pyruvate with the release of energy.

What are 'prokaryotic organisms'? What are some examples?
Explanation:
Prokaryotic organisms are type of cells that are clearly different from eukaryotic cells (human or plant cells), since they lack nucleus and other type of organelles and differ with size. ( some of them have flagella which helps these cells to move)
Example: Any type of bacteria can be considered as a Prokaryotic cell
Prokaryotic organisms are organisms that lack a true nucleus or in other words that have a primitive nucleus. This includes bacteria, E-coli, etc.
What is the difference between prokaryotes and eukaryotes?Eukaryotes are the organisms that have a well developed nucleus. They also have membrane bound cell organelles. These are generally multicellular.
Prokaryotes have a primitive nucleus, and the organelles are also not membrane-bound. These are unicellular.
Prokaryotes are divided into bacteria and archaebacteria. Most of them are small, single-celled and relatively simple. Example cyanobacteria, bacteria, E-coli, etc.
Thus, the organisms like bacteria, which lack a true nucleus are called prokaryotes.
