WHAT IS STIMULI?
A stimuli is anything that can trigger a physical or behavioral change.The changes in the environment to which living things respond are called stimuli. The living things show response to external stimuli such as heat, light , touch, sound, smell, taste, water and chemicals.It can be internal or external both.When diverse organs works collectively in a scientific way to supply a reaction to the stimulus, this is known as coordination.Stimuli is essentially anything that triggers a receptor for one of those senses.You can understand this with an example that would be the receptors on our skin which sense a stimulus like pain.

What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes.
Hence, DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.

Transform fault boundaries are the plates that move one past another without causing damage or destruction to the crust, these form when two plates move in the opposite direction or in the same direction.
At transform fault boundaries plates moving in opposite directions have a tendency to get stuck which leads to a high amount of energy formation. There is no damage or destruction that takes place nothing occurs but earthquakes along with the fault.
what is photosynthesis
Answers
Answer:
please tell me you know, my hands are literally shaking at how easy this question is
Explanation:
the answer is photosynthesis is a way for plants to make oxygen
still not enough information? they convert carbon-dioxide and water into oxygen and sugar, so they eat the sugar making their own food, put plants are living if they eat sugar. so they also have cellular respiration from mitochindria (photosynthesis is from chloroplasts and chrolophyll inside the chloroplast) and plants BREATH OUT SOME CARBON-DIOXIDE and produce more Oxygen than carbon-dioxide, thus providing the earth with Oxygen

SUBNITI
Answers
The plants releases oxygen as a byproduct of photosynthesis. this oxygen molecules diffuse through the atmosphere which are inhaled by birds. The correct option is B.
What is photosynthesis?Photosynthesis is the process of making their own food by plants using carbon dioxide and water in the presence of sunlight and chlorophyll.
During photosynthesis, plants release oxygen as a byproduct which diffuses in the atmosphere and get inhaled by the organisms.
Photosynthesis' principal role is to transform sunlight into chemical energy and then hold that chemical energy for later use. This process powers the majority of the planet's living systems.
Photosynthesis is the process by which water and carbon dioxide are converted into glucose and oxygen. The plant consumes glucose as food and produces oxygen as a waste product.
Cellular respiration is the process by which glucose and oxygen are converted into water and carbon dioxide. Water and carbon dioxide are byproducts of the process, and ATP is the energy that is produced.
Thus, the correct option is B.

Loni makes a diagram to help organize what she has learned about the gas laws.
Which label belongs in the region marked X?
involves changes in temperature
has a constant volume
shows an inversely proportional relationship
does not describe pressure changes
Answers
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.
