Answer:

The correct answer is option C, highest density

Explanation:

The density of air in the atmosphere is the maximum where the largest number of air particles are found and also they are squeezed by the pressure of air above it into a compressed volumetric space.  The maximum squeezing pressure will be at the lowest layer of atmosphere i.e troposphere.

The air density (i.e the number of air molecules per unit volume of atmosphere) is the highest near the earth’s surface/sea surface. Thus, Troposphere being the lowest layer has the maximum air density.

Why is the Lancelet a chordate, but not a vertebrate?
nika2105 [10]

Lancelet is a chordate but not a vertebrate because it lacks a backbone

Explanation:

The subphyla of the phylum Chordata are - Vertebrata, Urochordata and cephalochordate

Those chordates with a structural backbone belong to Vertebrata.

Urochordates and cephalochordates lack a backbone and hence are termed invertebrate chordates.

Lancelet is an invertebrate chordate of the subphylum – Cephalochordata.  

The lancelets consist of a notochord that extends right from the head till the tail at the dorsal surface. The notochord acts like the backbone and provides support and a semi-flexible structure to aid in the movement of the organism.

They lack a developed nervous system like vertebrates but only has a dorsal nerve tube .

Plants use sugars as
Pachacha [2.7K]

Answer:

a fuel for cellular respiration and a starting material for making other organic molecules.

Explanation:

Plants have the ability to produce sugars by the process of photosynthesis. Plants can convert the inorganic CO2 from the air into the organic nutrients such as sugars. Plants store sugars so that they can serve as a source of ATP for the cells as and when required. The sugars enter the process of cellular respiration and are oxidized into CO2 and H2O. In addition, the energy of chemical bonds of the sugars is used to form ATP molecules.

Plants also use sugars to synthesize other organic molecules. For example, several intermediates of Kreb's cycle can serve as precursors for the synthesis of amino acids. Amino acids are joined together to form different proteins.
