Which is the best definition of a phylogenetic tree

Answers

Answer 1
Answer:

The options attached to the above question are given below:

A. A table of classification that is based only on physical characteristics

B. Eight levels of taxonomic categories that are used to classify organisms

C. A branching chart that depicts evolutionary relationship among organisms

D. Organisms organized based on structure and genetic comparisons

ANSWER

The correct option is C.

A phylogenetic tree refers to a diagram, which represents evolutionary relationships that exist among organisms. Phylogenetic tree has many branches, which represents how different species evolved from a series of common ancestors. The relationships among the living organisms is usually based on the similarities and the differences in their physical or genetic features. A phylogenetic tree can be described as rooted or non rooted based on the depth of information they offer.

Describe the function of each of the following in protein synthesis; rRNA, mRNA, and tRNA

Answers

Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. 5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. 

Kelp plant have been known to grow up to _______. a. 1 foot per week b. 2 inches per day c. 10 inches per day d. 1 inch per hou

Answers

Kelp plants have been known to grow up to b. 2 inches per day. Correct option is B.

Kelp is a type of marine algae that belongs to the group of brown algae known as Phaeophyceae. It is a multicellular organism that forms large underwater structures known as kelp forests in shallow, nutrient-rich coastal waters. These kelp forests are highly productive and provide essential habitats for a diverse range of marine organisms.

Kelp has an impressive growth rate compared to many other plants. Its growth rate is influenced by several factors, including environmental conditions and the species of kelp. Some kelp species can grow incredibly quickly under optimal conditions. Kelp is a type of large brown algae that grows in underwater "forests" in shallow, nutrient-rich marine environments. They are known for their rapid growth rates, with some species capable of growing several centimeters or inches per day under optimal conditions.

The process of spreading culture traits from one society to another.

Answers

Answer: The correct answer is Cultural diffusion.

Culture is defined as the characteristics of a particular group of people, which includes various aspects like their language, religion, social habits, dance, music, food. In simple words, it describes the way of living of a particular group of people.

Cultural diffusion is a process through which the cultural traits are passed from one society into another society. Through this process, people become culturally rich as their ideas and knowledge is broadened.

This process is accompanied through transportation, migration, advanced communication ( like using twitter, instagram, mass media etc.)

Diffusion-process of spreading culture traints from one society to another...in other words the spreading of something more widely
