Answer:
mutualism
Explanation:
Mutualism is a type of symbiotic relationship between two organisms in which both benefit and neither is affected negatively in any way.
Mutualism can be in the form of resource-resource when it involves an exchange of resources between the organisms, service-resource when a resource is being swapped for a service or, service to service when it involves exchange of services between the two organisms.
In this case, the clownfish offers protection service to the sea anemone while the sea anemone in turn also offers protection to the clownfish. This is a service-service mutualism.
B. Perissodactyls
C. Artiodactyls
D. Sirenians
Answer:
Messenger mRNA: contains the genetic blueprint to make proteins.
Transfer TRNA: They translate mRNA into proteins. They carry amino acids on its third aceptor site to a ribosome complex.
Ribosome rRNA: They form ribosomes essential in protein synthesis.
Explanation:
B. Both are multicellular and haploid, are often found in fossil remains, and have cell walls made of cellulose.
C. Both have cell walls made of cellulose, have xanthophyll as their chief photosynthetic pigment, and are multicellular.
Answer:
The correct answer is statement A.
Explanation:
Green algae belong to the division Chlorophyta and comprise about 9000 to 12000 species. Like higher plants, green algae possess photosynthetic pigments like carotene, chlorophyll a and b, and xanthophyll, in a similar proportion as found in higher plants.
A cell of green algae can be sessile or motile, and exhibits a central vacuole, and possesses a two-layered cell wall formed of cellulose and pectin. The storage of food takes place in the form of starch in the pyrenoids. Thus, due to the similarities in the features between the plants and green algae, it is considered that the embryophytes or the lands plants have emerged from green algae. Hence, statement A supports the belief.
Most scientists believe that green algae are the ancestors of plants due to their similar biochemical features. These include having cell walls made of cellulose, the storage of food material as starch, and the presence of chlorophyll a and chlorophyll b.
According to most scientists, the belief that green algae are the ancestors of plants is best supported by the statement: Both have cell walls made of cellulose, store food material as starch, and have chlorophyll a and chlorophyll b. These characteristics highlight the similar biochemical features that underline the evolutionary relationship between green algae and plants. The presence of cell walls made of cellulose provides structural similarities. Storage of food material as starch indicates similar metabolic processes, and both having chlorophyll a and chlorophyll b reveals their shared capacity for photosynthesis, a defining feature of plants.

Answer:
There is no difference between Eukaryotic and prokaryotic codons. All 61 codons and 20 amino acids are same. Start codons are also same.
The genetic code is essentially universal, with both eukaryotic and prokaryotic organisms using the same mRNA codons to specify the addition of amino acids or the termination of protein synthesis during translation. The start codon is typically AUG, and it also codes for the amino acid methionine. The uniformity of the genetic code across different life forms suggests that all life on Earth shares a common origin.
Codons are three-nucleotide sequences in mRNA that specify the addition of a specific amino acid or the termination of protein synthesis during translation. There are 64 possible mRNA codons comprising of combinations of A, U, G, and C. Out of these, three are stop codons that indicate the termination of protein synthesis. Typically, AUG is the start codon for initiating translation, and it also encodes for the amino acid methionine.
The genetic code, which is the relationship between an mRNA codon and its corresponding amino acid, is essentially universal and alike for both eukaryotic and prokaryotic organisms, implying that all life on Earth shares a common origin. Such a universal genetic code strongly supports the theory of common descent for all life on Earth.
