The plasmid is an extra-chromosomal small circular and double stranded DNA molecule present in the prokaryotic cells. These are often found in some eukaryotic cells also. The plasmid DNA carries the genes which are responsible for the antibiotic resistance for the prokaryotic cells.
Answer:
Among others, two adaptations might be
- Avoiding corporal heat loss
- Increasing oxygen absorption
Explanation:
Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:
- Avoiding heat loss. Temperature tends to be very low at highs, so, to <u>avoid heat loss,</u> animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate.
- Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown.
- Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements.
- Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
Cranial nerve V do not have somatic motor fibers that control the extra-ocular muscles. The extraocular muscles are innervated by three cranial nerves, oculomotor nerve , trochlear nerve, abducens nerve.
Trigeminal nerve is the fifth cranial nerve . Its primary function function is to provide sensory and motor innervation to the face. It is main function which transmitting sensory information to the skin, sinuses, and mucous membrane in the face. That nerve is communicates touch , pain and temperature to brain.
Three cranial nerves carry purely sensory information and four cranial nerves carry almost entirely somatic motor information. The remaining cranial nerves carry some combination of sensory, somatic motor and parasympoathetic information.

Answer:
How does the Nervous System interact with the Skeletal system? The brain in the nervous system controls the position of bones through muscles and sensory receptors in joints between bones send signals about body positions to the brain. … The nervous system regulates he speed that food moves through the digestive tract.
Explanation:
Answer:
C
Explanation:
<em>The error that the student made was to place the containers for the different fruits in different areas around the school.</em>
In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.
<u>The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.</u>
The correct option is C.
