It is divided into four sections. These sections are termed as lobes. The frontal lobe, occipital lobe, parietal lobe and the temporal lobe.
Hence, the correct answer is option A
Answer:
Fossils are the greatest and simplest evidence of the presence of the organisms that existed many years ago.
Deoxyribo Nucleic Acid (DNA) is called as “coil of life.” According to the Darwin’s theory about 8 percent of human genome is made up from viral DNA which a person has accumulated through infections and diseases.
The case studies helps in figuring out the total evolution of species and organisms.
<u>Explanation:
</u>
<em>Fossil Records
</em>
But now Fossils are the feces and the footprints of the organisms which confirm the presence of an organism which are now extinct or rare to find.
<em>DNA evidence
</em>
DNA of an organism has sequences which mutate over a period of time and results in changes in organism’s genetics which later on evolve into new specie. Hence, the DNAs help to find the ancestors of the organism and also figure out the organism specifically related to. The process of study of evolution is known as Phylogenetics.
<em>Case Studies
</em>
The finch of Galapagos of Darwin’s is one of such example of evolution. The Galapagos Island helped in finding out the evolution occurred when the finches were secluded due to the geographical barriers.
Answer:
Symbiosis
Explanation:
Termites are the important insects due to its role in in nutrient recycling in the terrestrial ecosystems. Termites eat wood. The wood contain cellulose, a complex carbohydrate which is cannot be digested by most insects such as termites. For the breakdown and digestion of wood is carried out by the microorganisms present in the hindgut of the termites. The microbes live in the gut as a symbiont. The microbes break down cellulose into simple sugars and fatty acids which are easily absorbed into the cells of the termites.
During the development of human, the fetus is
prenatal human in between the embryonic state and during the birth. The stage
of development of a fetus begins at the gestational age of eleven weeks. The
fetal stage is recognized when an embryo develop to the point where the major
body organs is present.
