What are some examples of positive feedback mechanisms? In these cases, the positive feedback loop always ends with counter-signaling that suppresses the original stimulus. A good example of positive feedback involves the amplification of labor contractions. The contractions are initiated as the baby moves into position, stretching the cervix beyond its normal position. What is […]

What 3 things do seeds need to germinate?
What 3 things do seeds need to germinate? Optimizing Germination We know that seeds need optimal amounts of water, oxygen, temperature, and light to germinate. What do you think seeds need to grow? Seeds need the proper temperature, moisture, air, and light conditions to germinate. All seeds have optimal temperature ranges for germination (Table 1). […]
Can you identify forms of communication that use electromagnetic waves?
Can you identify forms of communication that use electromagnetic waves? Telescopes like the one above pick up microwaves from space. Microwaves are also used for radar, cell phones, ovens, and satellite communications. The diagram also shows different parts of the spectrum: radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Which […]
What is an example of classifying?
What is an example of classifying? The definition of classifying is categorizing something or someone into a certain group or system based on certain characteristics. An example of classifying is assigning plants or animals into a kingdom and species. An example of classifying is designating some papers as “Secret” or “Confidential.” What are the major […]
What are the two types of overcurrent?
What are the two types of overcurrent? Types of Overcurrent. The three major categories or types of overcurrent are overload, short-circuit, and ground-fault. Why relay is used in PLC? Relays are used to isolate one voltage level from another. A relay is used to energize the starter, which, in turn, switches the motor voltage while […]
Does gold float in water?
What are periods in 4th grade math?
What are periods in 4th grade math? The digits in large numbers are in groups of three places. The groups are called periods. Commas are usually used to separate the periods. What 3 digits are in the unit period? The answer is 817. Further explanation. The groups are called periods, i.e., Let us say in […]
Does chlorophyll convert sunlight to energy?
Does chlorophyll convert sunlight to energy? Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Can […]
