Answer:
Epistasis
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants
In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.
The chronological order of the response brought about by the nervous system is as follows.
1. Sensory receptors in the arteries detect low oxygen levels.
2. Sensory neurons generate an impulse.
3. The central nervous system relays an impulse to certain brain regions.
4. The brain sends signals through motor neurons.
5. Isabel's breathing rate increases.
The response to a stimulus is called a reflex action and the pathway traveled by the reflex action is called the reflex arch. A reflex action is an automatic involuntary response to a stimulus which minimizes any damage to the body. During conditions of low levels of oxygen in the body, the receptors detect the stimulus of low oxygen levels which could pose a threat to the individual and sensory neurons generate an impulse. It reaches the central nervous system and then the brain. In turn, brain sends signals through the motor neurons that carry a message and help in increasing the breathing rate of Isabel.
Hi,
The rda is designed to be averaged over several days.
- true
(average across a number of days, because body is good at storing based on solid, reliable evidence and observations).
The definition of Xylem is “the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps form the woody element in the root system. Therefore the answer is “transport water and minerals upward.” I hope this helps!
Environmental change has to do with any kind of alteration that occurs in the natural environment.
