It is the increase of carbon dioxide.

The correct answer is the option (d) the increase of carbon dioxide.

The increase of carbon dioxide in the earth's early atmospheric conditions made the aquatic dwelling organisms to adapt into terrestrial dwellers. Volcanic eruptions released a few gases, of which, carbon dioxide was abundantly released. It is a vital requirement for all living organisms. The first terrestrial plants appeared which used the carbon dioxide for the synthesis of food by the process of photosynthesis. Thus, this continuous availability of carbon dioxide helped the land dwelling plants to evolve. This increased the oxygen content in the atmosphere which made the animals to evade the terrestrial habitat.

The build up of ozone was not an earth's early atmospheric condition and the stromatolites were the sedmientary rock layers of water bodies like oceans. The formation of rust on the earth's crust did not help the land dwelling animals to evolve.

Thus, the increase in the carbon dioxide helped the land dwelling oragnisms to evolve.

<h2>Endothermic Process</h2>

Explanation:

An example of endothermic process is :

Heat is needed for water to boil.

Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.

Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.

What kind of fossil would a gastropoda shell must likely be?
DiKsa [7]
You didn't give any answer choices (i'm answering this through research and what i already know)

the first is fossilized dung, and that's not generally gastropod shells. A carbon film would be something thin, seeing as it's a film, and gastropods aren't that. A gastrolith is a stone swallowed by an animal to help with digestion, and that's also not a gastropod. 

<span>Gastropod fossils may be molds, but usually aren't. Still, they can be. It's a better answer than; film or stomach stones.</span>

Evolution can be guided by random processes. What is the effect called when some genotypes are lost in a small population over t
soldi70 [24.7K]

Answer:

Genetic drift

Explanation:

Genetic drift is defined as the random change in allelic frequencies from one generation to the other.

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.  

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.

Plants do not have a digestive system like us.why do they not need a digestive system
umka2103 [35]
All they need for their living is carbondioxide in air ,water and some nutrients .so basically their roots are responsible for collection of water which contains life giving nutrients .but we take food as a solid substance which hasto be converted into energy
