Answer:
Option (4).
Explanation:
Phosphatidylinositol4,5-bisphosphate (PIP2) is the phospholipid present in plasma membrane. This lipid is important for the cell communication and cell signalling process.
The PIP2 can cleave and give two main products are DAG (diacylglycerol) and IP3 ( inositol 1,4,5-trisphosphate). These two molecules are important for the cell signalling.
Thus, the correct answer is option (4).
The most responsive of the three different types of cones to various light wavelengths. When light is present, a cone may become entirely depolarized if the sunlight is of a wavelength that is not optimal.
<h3>What do
the eye's rods and cones do?</h3>
Rods are in charge of seeing in dimly lit environments (scotopic vision). They have poor spatial acuity and do not integrate color vision. Cones are responsible for color vision, high spatial acuity, and activity under higher light levels (photopic vision).
<h3>In the eye, how many rods are there?</h3>
The total number of rods inside the human retina (91 million) is significantly higher than the total number of cones, despite the fact human perception of average daytime ambient light is dominated by cone-mediated vision (roughly 4.5 million). As a result, over the majority of the retina, rod density is substantially higher than cone density.

Fossil Fuels Affect the Environment in the Following Ways:
1. When we burn coal, oil, and natural gas for fuel, too much carbon enters the atmosphere at one time. The carbon combines with oxygen to form carbon dioxide (CO2), a greenhouse gas. Greenhouse gases are contributing to global warming because they trap more of the Sun's energy in the Earth's atmosphere.
2. Due to the burning of Fossil Fuels, Some Poisonous Gases like Sulphur Dioxide, Nitrous Oxide, Methane and Carbon Dioxide, Which lead to Widespread Pollution in The Atmosphere.
3. This maybe a bit Difficult. Burning of Fossil Fuels causes Acid Rain. Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
4. It also releases Radioactive Substances or Radiances which Can be Pretty Explosive.
Hope this much helps!
Definitely Matter notes.. Matter is made up of any and almost everything.! It cannot be changed or destroyed, is gas, solid or liquid and is made up of atoms (isotones)
