Which sense does not go through the thalamus?<span>One, this is the only sense that does not travel to the thalamus before accessing the fore brain. The thalamus, if you remember, is the relay center for all sensory signals. Nearly all receptors send signals through the thalamus first, which then sends the signals to the proper areas of the brain for perception</span>
<u>Answer:</u>
Cyanobacteria start producing pure oxygen around 200 million years ago.
<u>Explanation:</u>
Many scientists believed that Earth did not have any oxygen. Cyanobacteria or the blue green algae are the microbes which produced oxygen for the first time with the help of photosynthesis. This was around 4.5 billion years ago: after Hadean eon.
They were very simple, but they produced oxygen in the early earth’s atmosphere. So, they brought evolution on earth. This “blue-green algae” exists in salt water, rocks and soils and play a major role in maintaining the ecosystem.
The regression equation is:
y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058

</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748
y = 1.15 + 0.0629508 + 0.0060606 + 0.935748
y = 1.3125862

x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
Answer:
Water shed is created when an area or land separates the water flowing to different rivers, basin and seas.
Explanation:
Water shed are of different types-
- Large water sheds-Contain well developed channel networks.
- Small water sheds-Contain dominant land phase.
- Urban watershed-It is dominated by building,roads,pavements.
- Agriculture water shed-
- Forest water shed-Evapotranspiration is the dominant component of the hydrologic cycle.
- Mountain water shed-mountain is the dominant component that separates the water flow.
- Desert water shed-Sand dunes sand mounds that are formed by blowing air causes separation of water flow.
- Coastal watershed-Coastal area may partly be urban and is dynamic contact with sea.The hydrology is influenced by tidal action.
The oxygen is inhaled to the blood vessel which brings the oxygen to a cell.
