The connective tissues and the epithelial tissue differ in their structure in the way their cells are organized. The cell of the epithelial tissue are organized in a closed-packed pattern, while the cells of connective tissue are organized in spread out pattern. Moreover, the connective tissues has blood vessels, but the epithelial tissue does not.
The epithelial tissues serve the purpose of protection. Protective layering is formed by the epithelial tissues in the body. The connective tissue such as bone provides support to the body. The blood vessel connectivity helps in the transfer of the newly formed blood cells.
The appearance of a person is determined by the tissues and other components. The skeletal determines the basic structure of the person. The epithelial tissues give more specificity to the figure of a person. The fats helps in determining the shape of the eyes and cheeks.
The fat in the cheeks is supposed to help the new born infants to suckle and chew. Moreover, it provides padding to the temporalis muscle while chewing. The fat behind the eyes helps in preventing damage to the eyes which may be caused if they rub with the bones of the skull.
It will be hard to open and close one's mouth if the temporalis muscle of a person is damaged. This will make forming words properly difficult. The damage to orbicularis oculi will make the blinking extremely difficult. The facial expressions will be distorted in such cases. The damage to the orbicularis oris will make the movement of the mouth difficult, which will cause poor articulation.
Answer:Eukaryotic cells are generally larger and more complex than prokaryotic cells. They also contain a variety of cellular bodies called organelles. The organelles function in the activities of the cell and are compartments for localizing metabolic function.

pluto
Explanation:
the others are formed from other things
Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.
Explanation:
Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.
They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.
The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.
When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.
Examples:
- Kangaroo - Australia
- Nilgiri Tahr, - Nilgiri Hills, India
- The Redwood trees of West Coast of the USA
- Plants like kalo, sumac of Hawaii
The smaller a population, the greater the potential effect of genetic drift on gene frequencies.
Genetic drift is an evolutionary term which refers to the random changes in a population's allele frequencies. These changes happen by chance due to the random selection of alleles from the genetic pool in each generation. Genetic drift can lead to either loss of some alleles or the fixation of others (100% frequency). The effect of genetic drift is stronger in smaller populations. This is because, the larger the population, the larger the sample size and the slower the result of genetic drift.
