The hydra has a nervous system characterized by a nerve net. A nerve net is a collection of separate, but "connected" neurons. Neurons are connected by synapse. Communication between neurons can be in both directions at the synapse within a nerve net. The nerve net is concentrated around the mouth. Unlike higher animals, the hydra does not have any grouping of nerve cell bodies. In other words, there are no ganglia.
The hydra does have specialized cells for touch and chemical detection though.
1st, 2nd, 4th, it’s hard they all seem to be reasonable answers ahah
Answer:
b. CO₂ gas and droplets of sulfuric acid
Explanation:
Atmosphere of Venus -
Venus atmosphere is occupied by the layer of gases .
The composition being , carbon dioxide which is very hot and dense in comparison to the carbon dioxide of the Earth .
<u>The pressure on the planet Venus is 93 bar with a temperature of 740 K.</u>
<u>The atmosphere of Venus have Opaque clouds made of sulfuric acid .</u>
Hence , the answer is CO₂ gas and droplets of sulfuric acid
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (9.3 MPa), roughly the pressure found 900 m (3,000 ft) underwater on Earth.[1] The Venusian atmosphere supports opaque clouds made of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging.[1] Aside from carbon dioxide, the other main component is nitrogen. Other chemical compounds are present only in trace amounts.
Answer:
Barycentre of planet lies at 1.068 radii.
Explanation:
- Jupiter is a Jovian planet and has mas of all rest of the planet combined and is 2.5 times as massive as other planet s and has a mass as similar to that of a brown dwarf.
- Jupiter lies about 1.068 solar radii from the Sun's center and scientists also suggest that Jupiter mass is shrinking due to the atmospheric variation by the sun.

What is the 1000 year period after the fall of Rome called?
The 1000 year period after the fall of Rome is called Middle Ages. This is a period where the Odovacor, German prince had sway the power of the Roman army of Italy.
