Fill in the blanks on the table with the names of the atmospheric layers, their chemical
andrew11 [14]

Answer:

Thermosphere, mesosphere , stratosphere and troposphere.

Explanation:

Thermosphere and exosphere are the layer that starts above 140 kilometers. In these layers of atmosphere, the temperature increases from colder to warmer and satellite travels in these layers of atmosphere. Mesosphere layer is present between 50 to 85 km while on the other hand, stratosphere is present between from 10 to 50 km and in this layer, aeroplane travels. Troposphere layer is present from the earth surface to 10 km and the temperature is decreases from warmer to colder. Hydrogen ozone is also present in this layer in very small amount.

1. state the characteristics of Chrysophytes.
GuDViN [60]

1. Chrysophytes

⇒ Unicellar

⇒ Present in water bodies with low calcium levels.

⇒ Golden yellow colour due to accessory pigment.

⇒ Cell walls made of cellulose and silica.

⇒ Free swimming.

⇒ Two unequal flagella.

2. Dinoflagellates

⇒ Dinoflagellates are essentially golden-brown, biflagellate, unicellular motile protists.

⇒ Golden brown is the primary color, but due to changes in the ratios of other pigments, it may also take on yellow, green, brown, or even blue forms.

⇒ Theca or lorica, composed of articulated and sculpted cellulose plates, is a stiff covering that typically covers cells.

⇒ One flagellum is transverse and the other is longitudinal, making the two flagella distinct (heterokont).

⇒ Mesokaryon is the name given to the big nucleus.

⇒ Chlorophyll a and chlorophyll c are found in plastids or chromatophores.

⇒ In the sea, certain dinoflagellates like Gymnodinium and Gonyaulax proliferate in vast numbers, turning the water red and resulting in the so-called "red tide."

⇒ Dinoflagellates in the ocean exhibit bioluminescence. such as Noctiluca.

3. Euglenoids

⇒ Unicellular protists called euglenoids, like the genus Euglena, are frequently found in freshwater.

⇒ The pellicle, a protein-rich cell membrane, exists in place of the cell wall.

⇒ They bear two flagella on the anterior end of the body.

⇒ A small light sensitive eye spot is present.

⇒ They can prepare their own food because they have photosynthetic pigments like chlorophyll. They act like heterotrophs when there is no light, though, by catching other tiny aquatic creatures.

⇒ They are referred regarded as the connecting link between plants and animals since they exhibit both plant and animal-like characteristics, making it difficult to categorize them.

4. Slime moulds

⇒ Chlorophyll does not exist in them.

⇒ Only the plasma membrane encloses them. The spores, however, contain cellulose cell walls.

⇒ They often reside near decomposing vegetation.

⇒ They have a diverse spectrum of coloring.

⇒ They are saprotrophic or phagotrophic feeders.
