Answer:
C. Organs are composed of tissues and tissues are composed of groups of similar cells.
The answer is D, bacteria.
Neurons are constantly carrying action potentials (meaning electrical signals) in order to result in a certain action carried out by the body. Therefore, Neurons need a high amount of ATP to carry an action potential throughout the nervous system to be processed by the brain and then initiate a motor (physical response)
For example if you touch a hot stove, sensory neurons will take the "hot" information from the hand to the spinal cord which has relay neurons which connect the action potential (which is the information) to the brain. The brain in response will interpret that information and initiate a motor response. Which will result in you taking your hand off the stove. This entire process of responding to stimuli takes a lot of energy to take place. Just the brain itself takes about 20% of all daily basal energy (which is the energy required to keep you alive).
Answer:
- In Rho-dependent termination, an omega factor is responsible for displacing the core enzyme from the DNA template.
Explanation:
Rho factor is the factor responsible for the termination at places in the genome where the use of an intrinsic terminator is not possible. Omega factor is not responsible for displacing the core enzyme from the DNA template.
Hypothalamus
The hypothalamus maintains a steady internal environment for the body.
The hypothalamus is a complex part of the brain that is located under the thalamus and above the pituitary gland. One of the main roles of the hypothalamus is to maintain homeostasis by keeping the human body in a balanced condition. The hypothalamus plays a part in various important functions of the body such as appetite and weight control, body temperature, emotions, sleep cycles, stress, blood pressure and levels of hormones in the circulation.
