The correct answer is the option (D) Both are not a mammal, are multicellular, and are heterotrophic.
Keys in biology are used to identify the different species based on the easily identifiable features of the organism. A dichotomous key consists of a series of questions on features like habitat, mode of nutrition, class to which they belong and other features, with each question having two answers describing the characteristic features of an organism. The series of questions begin with a broader characteristic feature becoming narrow gradually and helping in the identification of the organism.
Both the house sparrow and a cobra cannot synthesize their own food and depend on other organisms for food. Hence they are heterotrophic. They are multicellular in nature. A cobra belongs to the class Repltiles and a house sparrow belongs to the class Aves. Thus, a house sparrow and a cobra are similar to each other in being multicellular, heterotrophic and not belonging to the class mammals.
Answer:
A) Your cells have a nucleus; those of protists do not.
Explanation:
Your cells are eukaryotes (which DO have nuclei) and protists don't.
a. The Calvin Cycle: is a cyclic pathway that produces three carbon molecules from CO 2.
Answer: Helps the plant breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.
Answer:
The correct answer is option - a. some genetic functions may not occur.
Explanation:
A plasmid is an accessory genetic molecule which is small, circular dsDNA that is present with the chromosomal DNA in a bacterial cell. Both plasmid and chromosomal DNA are different from each other.
The plasmid generally has some genetic functions such as antibiotic resistance which help to defend itself. These genetic molecules. In some bacterial cells plasmid also helps in replication in bacteria.
Thus, the correct answer is - a. some genetic functions may not occur.
