Name three types of connective tissue.

Answers

Connectivetissue is further classified as loose connective tissue, dense connective tissue, as well as specialized connective tissue.

What is connective tissue?

Tissue that supports, protects, and structures the body's other tissues and organs.

Connective tissue also stores fat, aids in the movement of nutrients and other substances between tissues and organs, and aids in the repair of damaged tissue. Cells, fibers, and a gel-like substance comprise connective tissue.

Connective tissue is basically characterized into three types: loose connective tissue, dense connective tissue, and specialized connective tissue.

Connective tissues connect structures, provide a framework and support for organs and the body as a whole, storefat, transport substances, protect against disease, and aid in tissue repair. They can be found all over the body.

Thus, these are the three basic types of connectivetissue.

Which of these would most likely result in a change to the current classification of an organism?

Answers

Hello. This question is incomplete. The full question is:

"Which of these would most likely result in a change to the current classification of  an organism?  A- Discovering organisms with similar physical traits in the fossil record  B- Finding a related organism that was previously considered extinct  C- Linking the organism to different ancestors through DNA sequencing  D- Observing organisms that occupy the same ecological niche. "

Answer:

C- Linking the organism to different ancestors through DNA sequencing  

Explanation:

To formulate the oldest classifications, ecological and physiological characteristics were used, as well as all others that are available for the taxa in question. However, in recent years, classifications based on the similarity between genomes have been attempted, with great advances in some areas, especially when those from other fields of Biology are added to this information. Because of this evolution in the classification technology, a change in the current classification of an organism could occur by linking the organism to different ancestors through DNA sequencing.

The classification of living beings is part of the systematic, science that studies the relationships between organisms, and which includes the collection, preservation and study of specimens, and the analysis of data from various areas of biological research.
Hi There! :)

Which of these would most likely result in a change to the current classification of an organism?

An analysis of the DNA sequence of an organism  will most probably  result in a change to a current classification of an organism. 
>>>DNA analysis is one of the new reasons why organisms/species are being re-evaluated . Basic genetic analysis information can change our ideas of how closely two organisms/species are closely related thus, their classification can change.

In August 2005, Hurricane Katrina caused significant damage in several states along the Gulf Coast, including Alabama, Mississippi, and Louisiana. Thousands of people were evacuated from their homes due to flooding and other damage that was caused by the storm. Which type of limiting factor was Hurricane Katrina?A) density-independent factor
B) density-dependent factor
C) population-dependent factor
D) population-independent factor

Answers

The correct option is A.

A density independent factor refer to a weather or climate condition, which exert its influence on a population size without regard for the size of the population and its density. Limiting factor refers to any factor that put a limitation on the growth, abundance or distribution of a population. In the question given above, the Hurricane Katrina is a density independent factor because the hazardous event affected all the people that are resident in the affected areas.
Hurricane Katrina was an example of a density independent factor because this disaster affected everyone in the area. It did not selectively have an effect like a density dependent factor would.
