The best answer is the third option namely an enclosed nucleus.
One major difference between these two types of cells is that a prokaryote cell has no distinct nucleus enclosed with a membrane whereas in a eukaryote cell the genetic material, which is DNA, is packaged into chromosomes and found within a distinct nucleus that is enclosed with a membrane
Examples of prokaryotes are bacteria such as staphylococcus species found as commensals on the skin of man and Streptomyces soil bacteria from which the antibiotic streptomycin is derived.
Examples of eukaryotes are an amoeba, which is a unicellular protozoan that lives in water and a hepatocyte which is a liver cell in man.
Answer:
photosynthesis is a process utilized by autotrophs to produce the products required for cellular respiration. Unlike you and me, plants and certain other Autotrophs like bacteria; can’t consume other organisms. That being said, they still require nutrients to preform cellular respiration. Those nutrients are obtained through processes such as photosynthesis.
So in other words photosynthesis produces glucose and oxygen required for aerobic/anaerobic cellular respiration, and that’s how there related.
Answer:Terms in this set (10)
Mouth
Teeth chop food & saliva breaks down food
Esophagus
Tube that connects mouth to the stomach (peristalsis)
Stomach
Organ that releases acid and juices & mixes with food to create chymes
Small Intestine
Greatest amount of digestion takes place (if taken out, it would be 21ft long) (takes 4hrs to get to the small intestine)
Liver
Gland that releases bile and filters poisonous waste
Gall Bladder
Small organ that stores bile (you can live without it)
Pancreas
Gland that produces digestive enzymes and insulin
Large Intestine
(colon) Tube extending the small intestine where your indigestive food is ready for elimination
Rectum
Short tube at the end of the large intestine
Anus
Opening to the outside of the body
Explanation:
The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus. Recognizing how these organs work together to digest food is key to understanding how digestion works.
The correct answer is: stratosphere.
This is because their temperatures are rising instead of decreasing.
There are 4 primary layers of the atmosphere on Earth:
Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.
Stratosphere (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.
Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer
Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.
