Answer:
carbon source Earth's crust
Molecules that are present in the membranes of gram-negative bacteria and are the best-known pamps are called Bacterial lipopolysaccharides (LPSs).
Bacterial lipopolysaccharides (LPS) are the primary outer surface membrane elements present in almost all Gram-negative bacteria and it act as extremely strong stimulators of the innate or natural immunity in the diverse eukaryotic species ranging from insects to humans.
Eukaryotes are the organisms whose cells contain a nucleus and other membrane-bound organelles. eukaryote, any cell or organism that possesses a clearly defined nucleus. The first eukaryotic cells was evolved about 2 billion years ago. In this Cells with nuclei surrounded by a nuclear envelope with nuclear pores.

I believe that in this community the tadpoles are: the primary consumers. A n ecological community is the set of all populations of all species found in a given place. Primary consumers are mainly herbivores which feed on plants; which are the primary producers of all the energy in an ecosystem. In this case the tadpoles eat algae (primary producer) thus they are primary consumer.
The answer to this question would be: increased food height
Giraffe becomes tall because its food height is increased. In this case, the environmental pressure on Giraffe would be the increased height of the food.
The taller giraffe has access to higher food. Then, the giraffe with the higher chance of survival in this scenario would be the giraffe with a taller height.
Answer:
Over 95% of incoming ultraviolet radiation is absorbed in :
A. The Stratosphere.
Explanation:
- Stratosphere is the second layer of the earth's atmosphere that lies next to the troposphere.
- This layer experiences very little turbulence of air and is very significant because of the presence of Ozone layer in it.
- The UV rays entering the Earth's atmosphere, photo dissociates ozone into O₂ and O. But these molecules quickly recombine to form ozone.Thus, stabilizing the concentration of ozone in the atmosphere.
- During this photo dissociation UV radiations loses much of its energy. Thus, 95% of incoming Ultraviolet radiation gets absorbed in the Stratosphere.
- Absorption of ozone UV radiation increases exponentially with the thickness of ozone layer.
