Answer: A) Evolution or B) Natural Selection
Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!
However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.
Answer:
The correct answer will be option-E.
Explanation:
The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.
The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.
The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism
Thus, option-E is the correct answer.
Answer:
Carbohydrates contain the elements of carbon, hydrogen, and oxygen, and only those elements with a few others.
Lipids/fat contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples include: fats, oils, waxes, and certain vitamins (such as A, D, E, and K).
Proteins contain carbon, hydrogen, and oxygen like the carbohydrates and lipids, but they also contain nitrogen and often sulfur and phosphorus.
Nucleic Acids are the large biomolecules that are essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA. Consisting of Nucleotides, which are the monomers made of three components: a 5-carbon sugar (a phosphate group and a nitrogenous base).
The first blank is organelles, the second blank is nucleus, the third blank is eukaryotes, the fourth blank is mitochondria, and the fifth blank is flagella.
Hope this helped!!
Answer:
5' AUGAAGUUUGGCUAA 3'
Explanation:
The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.
The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.
For the DNA sequence;
3' TACTTCAAACCGATT 5'
The mRNA sequence will be synthesized;
5' AUGAAGUUUGGCUAA 3'
