Answer:
D
Explanation:
One of the reproductive strategies of terrestrial vertebrates is <u>the ability of fertilized eggs to develop away from the body of water.</u>
<em>Water is very important for fertilization in aquatic organisms and one of the biggest challenges posed by migrating to the terrestrial environment is desiccation of the eggs. Terrestrial vertebrates are able to overcome these challenges by making fertilization of eggs internal and the ability of the fertilized eggs to develop away from the body of water.</em>
The correct option is D.
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:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.
