What would happen if cell division was not controlled?
Activites within the cell cycle are monitered and controlled at specific stages, or checkpoints. Checkpoints in the life of a cell are like checkpoints during a mountain bike race. Officials monitor racers to ensure that competitors have enough water and food and that no one is hurt. If an official thinks a racer cannot compete the race because of injury, the racer will be removed from the race. Checkpoints during the cell cycle have a similar function. Special proteins at these checkpoints monitor cell activities and send this information to the nucleus. The nucleus then instructs the cell whether or not to divide. Cellsb will not divide if: - There are not enough nutrients to support cell growth. - DNA within the nucleus has not been replicated. - DNA ia damaged. Overall, it could create some uncontrolled cell division and mutations which could create huge problems.
Which types of electrical signals allow rapid long-distance communication within the nervous system?
Electrical Synapses
What substance on the plasma membrane helps identify chemical signals from outside the cell?
carbohydrates
What is the scientific definition of caudate nucleus?
Caudate nucleus is a nucleus that is located within the brain of numerous animals. The caudate nucleus is part of the learning and memory system located within the brain. One can find further information on the caudate nucleus via the Wikipedia website.
What is an example of how negative feedback controls the body's horemone levels?
Negative feedback is a process in which the body's hormones regulate and maintain homeostasis, or a state of equilibrium. This process is used to maintain stable internal conditions within the body, such as temperature, water balance, blood sugar levels, and hormone levels. Negative feedback occurs when hormones are released into the bloodstream, which then triggers an opposite response from the body to counteract the initial action. This is an example of how negative feedback controls the body's hormone levels. For example, when a hormone is released into the bloodstream, it can trigger the release of a second hormone that will inhibit or reduce the production of the first hormone. This is an example of negative feedback, as the second hormone acts as an inhibitor to the first hormone, which helps to maintain balanced hormone levels in the body. Additionally, some hormones can act as stimulators, meaning they can increase the production of another hormone, which will then reduce its own production. This is another example of negative feedback, as the stimulus hormone is stimulating the production of another hormone, which then helps to reduce its own production. In order to maintain a state of equilibrium, the body needs to be able to identify when the hormone levels are too high or too low and respond accordingly. Hormones can be regulated through a variety of mechanisms, including negative feedback, which is one of the most important ways in which the body regulates its hormone levels. Negative feedback helps to ensure that the body's hormones are kept in balance, which helps to maintain homeostasis.
What is the define for internal feedback?
Internal feedback refers to the process of gathering and providing feedback within an organization, typically from colleagues, managers, or supervisors. It is used to improve performance, communication, and processes within the organization.
Is true of feedback?
Negative feedback mechanisms work to prevent sudden severe changes within the body.
What is meant by positive feedback?
After someone does something they receive feedback from other people regarding their performance. Positive feedback may include praise, rewards, or recognition within their group.
Describe a negative feedback system?
Q: describe the negative- feedback system subject: Science A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system. example: it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream. ur wlcm (: SnazzyChazzy <33
To what frequencies within the spectrum do voice signals belong?
lasers
What is the importance of challanging fixed ideas within a team?
The importance of challanging fixed ideas within a team is to allow comparison with potentially useful ideas.
What is the difference between a reflex and a feedback mechanism?
The difference between a reflex and a feedback mechanism is that the former is done without action by the brain but the latter is consciously done with feedback from the brain. A reflex is the reaction to external stimuli. Feedback to the brain can be given due to external or internal (within the body) reason.
What is feedback loop and how does it work?
A feedback loop is a mechanism that is used to maintain homeostasis. In layman's terms, it is a checks and balances system within the body to keep hormone levels even.
Most often the integrating center in a feedback loop will be located within the?
The Central Nervous System
What signals that acts within the animal body are produced by endocrine glands?
hormones
What position within a structure indicates importance?
