Answer:
Answer is B. Positive feedback regulation can generate an abrupt, all-or-none response in which the cell moves from ignoring a signal to responding to it very strongly.
Explanation:
Positive feedback can be described as an example of feedback, which is a natural mechanism that amplifies the action of a system.
It can be better be explained further, as a situation whereby the blood pressure decreases and the response of the body also makes or causes the blood pressure to decrease the more.
Other examples of a positive feedback also include blood clotting, ripening of fruits , uterus muscle contraction, resulting to the stretching of the uterus during pregnancy.
False the goal was to cover the smear if it evaporates the smear is uncovered meaning the goal wasn’t meant. It could also be true though because you could just apply more dye to cover it up. So it might be true
The amoeba is made of one cell.
Answer:
Fill in the blanks.Asher wishes to apply the FITT principles to create a cardiorespiratory fitness program. He first must determine the frequency of his workouts. Asher learns that the American College of Sports Medicine (ACSM) recommends spending 3 to 5
days per week on cardiorespiratory conditioning. He understands that the intensity level he chooses will also affect the number of days per week he will work out. Asher is currently not very fit and does not like to work out at high-intensity levels, so he chooses to work out at moderate-intensity levels. According to the ACSM, lower-intensity levels require workout frequency to be more than 3 days per week with 5 days per week recommended. Asher determines that he will measure his workout intensity by counting the number of heart beats for 10 seconds and then multiply by six to convert to the number of beats per minute to determine his heart rate
.Using the ACSM's training guidelines, Asher reads that moderate intensity indicates that his heart rate range should be at 64 to 75%
of his heart rate maximum. He also understands that if he uses the talk test to measure his moderate intensity level, he should be able to speak in brief sentences and words. Asher decides that for optimal cardiorespiratory conditioning at moderate intensity his exercise time should be minutes in duration. After determining the exercise frequency, intensity, and time, Asher is now left to determine exercise type
.Through reading, he learns that for optimal motivation, training improvements, and injury prevention
, he should choose activities that he enjoys.
Answer:
Xylem developed to transport water from the plant’s roots to the rest of the plant.
Explanation:
A waxy cuticle is usually present to reduce water loss, whereas spines are often in place that help plants avoid being eaten by herbivores.
Stomata are key for gas exchange, and actually permit the release of water. Water is taken up through the roots, not the stomata
All plant cells have nuclei, which is the organelle in which DNA is stored. The seeds did not develop to provide a place for the storage of genetic information.
However, the xylem is an important part of the plant vascular transport system that ensures water is transporter from the roots to the leaves. This is an important adaptation for land plants as it ensures all parts of the plant get a water supply, particularly the leaves that are undergoing photosynthesis.
