Linnaean classification involvesa. only large, general categories of organisms.
b. only small, specific categories of organisms.
c. both large and small categories of organisms.
d. no categories of organisms.

Answers

Linnaean classification involves both large and small categories of organisms (c).

Further Explanation:

Carolus Linnaeus is widely known as the father of taxonomy. This refers to the system of naming as well as classifying the organisms and one of his major contributions was towards the growth of the hierarchical system of the classification of nature. This system involves 8 taxa, namely, kingdom, domain, order, phylum, genus, class, family, and species.  

This system includes both small as well as large categories of organisms and for most of the species, there are regional differences in their common names. Taxa are known to be the group that has biological meaning. According to this system, the three kingdoms were segregated into classes and they are further segregated into orders genus and species.

Linnaean classification involves  both large and small categories of organisms, hence option C is correct.

Linnaean classification is a hierarchical classification method for organisms. It employs a succession of layered categories, beginning with the broadest and most general and ending with the tiniest and most specific.

The seven main categories in Linnaean classification are: Kingdom, Phylum, Class, Order, Family, Genus, and Species.

Each category is subdivided into smaller categories, which are then subdivided into even smaller categories. Scientists can classify creatures with high precision because of this hierarchical approach.

Thus, the option C is correct.

An acorn with a mass of .0300 kilograms is hanging from a branch in a tree. It is 2.50 meters from the ground. What is the potential energy of the acorn?

Answers

The answer is 0.74 J.

The potential energy of the object is its stored energy. Gravitational potential energy is the stored energy of the object as the result of its height can be expressed as:
E = m · g · h
where
E - the potential energy of the object,
m - the mass of the object,
g - gravitational acceleration (g = 9.81 m/s²),
h - the height of the object.

It is given:
g = 9.81 m/s²
m = 0.03 kg
h = 2.5 m

Therefore:
E = m · g · h
⇒ E = 0.03 kg · 9.81 m/s² · 2.5 m
⇒ E = 0.03 · 9.81 · 2.5 kg ·m/s² · m
⇒ E = 0.74 kg ·m²/s²
⇒ E = 0.74 J

Therefore, the potential energy of the acorn is 0.74 J.

Answer:

Its 0.075

Which of the following would cause an error in DNA replication? A. DNA polymerase pairing A with G B. Helicase making a replication fork C. DNA polymerase checking the DNA D. DNA ligase connecting chunks of DNA

Answers

The correct option is A. DNA replication is the process by which two identical copies of DNA are produce from one original, parent DNA. The process occurs in all living organisms and it is the mean through which traits are passed from parents to offspring. A number of mechanisms has been put in place to ensure that base pairs are accurately copied during the process of DNA replication. For instance, pairing adenosine base with guanosine during the replication process will result in an error, which can have very severe consequences, if it is not corrected.
