Answer:
When carbondioxide gas is emitted from vehicles and industries and goes upward in the atmosphere. The carbondioxide gas combines with the rain water forming an acid called carbonic acid and make the rain acidic.
When rainfall occurs this acid comes to the ground and ocean and adversely affected the living organisms due to acidic nature. The marine animal's body comprise of shell and skeleton. This skeleton and shell are made from calcium, when acidification of ocean water occurs, the calcium dissolved and the body of animals are destroyed.
Answer: Great white sharks are one of the only animals capable of eating an adult tiger shark
Explanation:
The answers are:
- They are formed above Earth's surface - sedimentary rock.
- They form in Earth's crust or mantle - intrusive igneous rock.
- They are solid at room temperature - both.
- They are made of molten rocks called magma - intrusive igneous rock.
- They are made of weathered pieces of rock - sedimentary rock.
- They have a diverse composition. They may contain many types of minerals - both.

<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.
