Answer:
A - Lava
Explanation:
Prokaryotes were the earliest life forms, simple creatures that fed on carbon compounds that were accumulating in Earth's early oceans. Slowly, other organisms evolved that used the Sun's energy, along with compounds such as sulfides, to generate their own energy.

When scientists examine the gases ejected during a volcanic eruption, the majority of the gas is water vapor. How does the process of subduction provide a water source for volcanic gases?
Answer: Volcanic gases are gases given off by active (or, at times, by dormant) volcanoes. These include gases trapped in cavities (vesicles) in volcanic rocks, dissolved or dissociated gases in magma and lava, or gases emanating from lava, from volcanic craters or vents.
Answer:
When an oceanic crust and a continental crust converge, the denser oceanic crust subducts under the continental crust. During this process, seawater is added to the volcano’s magma. Much of this water is heated and ejected during an eruption as water vapor.
Explanation:
what are three pieces of evidence to support the theory of evolution?
Answer:
Explanation:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life.
Biogeography.
Fossils
Biogeographical evidence, fossil evidence, and anatomical evidence are three pieces of evidence to support the theory of evolution.
What is evolution?Evolution states the changes observed in organisms over time, this makes benefits the organism for its survival.
Anatomical evidence, support the theory of evolution, by comparing the anatomical structure of related species. Fossil evidence also provides evidence that how organisms evolve from the ancestor species.
Biogeographical evidence provides major clues about the relation between extinct and alive species, this benefits the theory of evolution. All this evidence supports the life formation around the earth and the relationship between organisms.
Therefore, biogeographical evidence, fossil evidence, and anatomical evidence support evolution.

Rachel Carson wrote in Silent Spring, "The chemical war is never won, and all life is caught in the crossfire." Respond
Answer:
Yes.
Explanation:
Yes, the statement is right because in chemical war, great damage occurs to all living organisms that has a bad effect on our environment. These chemicals are very dangerous so its usage in the war has long term effects on the environment and the organisms that live in it. Both the opponents receive great damage from this chemical war and the destruction of the natural beauty of the place vanished where this war occurs so this vanished of beauty and organisms is the defeat of both the opponents that fought this war.

Why Is DNA important for protein synthesis?
Answer:
The most important function of DNA is its ability to replicate itself repeatedly.
Explanation:
DNA makes RNA makes Protein. As you have learned, DNA is the genetic material of your cells and holds the information for making all the different proteins of your body. ... Translation converts the information in a series of three letter words in the mRNA into a sequence of amino acids, the building blocks of proteins.
DNA is important for protein synthesis because it holds all the genetic information necessary to synthesize all proteins of the cells that it required.
What do you mean by Protein synthesis?Protein synthesis may be defined as the process by which cells make proteins that are required for their metabolism and function.
DNA is the primary genetic material contained in the cell of all organisms. It is used to create proteins during protein synthesis because central dogma reveals the importance of DNA in the process of protein synthesis. DNA is considered the root of the central dogma.
Therefore, DNA is important for protein synthesis because it holds all the genetic information necessary to synthesize all proteins of the cells that it required.
