About 0.55 million or 550,000 years ago the earliest South Asian river dolphin evolved.
About 0.5 million years ago the South Asian dolphin evolved due to different environmental conditions. South Asian dolphin have very flexible necks due to no fusion of their neck vertebrae. They are using echolocation to navigate and search for prey.
Research indicates that South Asian dolphin diverged from a common ancestor around 550,000 years ago that lives in the Indus and Ganges basins so we can conclude that the South Asian dolphin evolved around 0.55 years ago.

Answer:
26 million years ago
Explanation:
A freshwater and salt-water biome refers to the body of water (aquatic biome) that makes up about 75 percent of the surface of planet Earth.
The freshwater biome is divided into three (3) major levels or zones and these include:
1. Littoral zone: it is the shore area of a freshwater and it can either be very wide or very narrow.
Some examples of organisms found in the littoral zone are:
2. Limnetic zone: it is the open water area of a freshwater.
Some examples of organisms found in the limnetic zone are:
3. Profundal zone: it is the bottom and deep water area of a freshwater.
Some examples of organisms found in the profundal zone are:
On the other hand, a salt-water biome is divided into four (4) major levels or zones and these include:
1. Intertidal zone: it comprises these organisms;
2. Pelagic zone: it comprises these organisms;
3. Abyssal zone: it comprises these organisms;
4. Benthic zone: it comprises these organisms;

Answer:
Life cycle is my answer
Explanation:
it might be wrong
Answer: I do think its a good idea cause it lessens pollution in the air we breathe in and stops us from burning fossil fuels
Explanation:
Banning passenger cars and promoting public transportation in cities is a good idea for reducing pollution and traffic congestion.
I believe that banning passenger cars and promoting the use of public transportation in cities is a good idea. This approach can help reduce air and noise pollution, alleviate traffic congestion, and improve overall quality of life. By encouraging people to walk, bike, or use public transportation, cities can create a more sustainable and livable environment for their residents.
One example of a city that has successfully implemented this approach is Copenhagen, Denmark. The city has an extensive public transportation system, including a well-connected network of bike lanes. As a result, more than 60% of residents commute by bike or public transportation. This has significantly reduced air pollution and traffic congestion in the city.
Additionally, adopting this approach can have numerous benefits, such as promoting physical activity, reducing carbon emissions, and improving public health. Overall, I believe that cities with comprehensive public transportation systems should consider implementing policies that restrict the use of passenger cars in order to create a cleaner, more sustainable urban environment.
Answer:
The correct answer is 18 ATP and 12 NADPH and noncyclic photophosphorylation can produce ATP molecule in the absence of cyclic photophosphorylation.
Explanation:
ATP and NADPH molecules are synthesized during light reaction of the photosynthesis which is utilized during the reactions of the dark phases. Dark reaction or Calvin cycle (C3 cycle) is the cyclic pathway of producing glucose triose phosphates (3C) from carbon dioxide and water. This reaction proceeds into 3 phases: carboxylation, reduction and regeneration.
First ATP and NADPH are utilized during the reduction step in the reduction of 3-phosphoglycerate to glucose-3-phosphate by the transfer of phosphate group from 6 ATP to 3-phosphoglycerate and 6 NADPH reduction as it donates an electron. Regeneration step also uses 3 ATP in conversion of G3P to RUBP molecules.
A total of 9 ATP and 6 NADPH are utilized in producing 3C G3P molecule, So, to produce 6C sugar molecule 18 ATP AND 12 NADPH are used.
During chemiosmosis synthesis of ATP, 4 protons produce 1 molecule of ATP which could be able to generate 3 molecules of ATP for each pair of NADPH. so, noncyclic photophosphorylation or Z-scheme will be able to produce ATP in the absence of cyclic photophosphorylation.
Thus, 18 ATP and 12 NADPH and noncyclic photophosphorylation can produce ATP molecule in the absence of cyclic photophosphorylation are the correct answer.
