Answer:
Solution : Combustion of Liquefied Petroleum Gas (LPG) is a chemical change. Because it is an irreversible reaction and new products, carbon dioxide and water vapour are formed and lot of heat is also produced during the reaction.
When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.

QUESTION 14
1 points
Save Answer
Answer:
The correct answer would be - AUGCUUAUC
Explanation:
The new mRNA strands are made by the process called transcription that involves an enzyme that helps to copy a segment of DNA or gene to produce a new RNA strand that encodes for the protein. In this process, a new RNA strand copied the complementary to the sequence of DNA strand. It means adenosine is copied into its complementary form uracil in RNA, Thymin to adenosine, cytosine to guanine and guanine to cytosine.
Original strands: TACGAATAG
new RNA strand: AUGCUUAUC

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
population II stars
red dwarf stars
population I stars
brown dwarf stars
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.

Where do most volcanoes form?
A. Near plate boundaries
B. In the middle of tectonic plates
C. Where there is no plate movement
D. On a supercontinent
Explanation:
Most volcanoes form at the boundaries of Earth's tectonic plates. These plates are huge slabs of the Earth's crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. ... Sometimes, the plates collide with one another or move apart.
The International Astronomical Union (IAU) defines a constellation by its:
boundary
star pattern

Greek name
Answer:
Each constellation is a region of the sky, bordered by arcs of right ascension and declination. ... Together they cover the entire celestial sphere, with their boundaries adopted officially by the International Astronomical Union in 1928 and published in 1930.
So I would say its A : Boundary
Explanation:
- Eijiro <3
Love the pfp by the way! :D
The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.
What is International Astronomical Union?In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.
The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.
The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
Thus, the correct option is A.

On the surface of a plant's roots are thin projections called root hairs. Which of the following best describes the purpose of these root hairs?
They provide protection for the growing roots.
They help anchor the plant to the soil to make it sturdier
They store excess sugar produced during photosynthesis.
They allow for an increase in surface area so more water and nutrients can be absorbed.
Answer:
second one is the best which describes roots
The main function of root hairs is to absorb water and minerals from the soil.
What is the function of root hairs?The function of root hairs is to absorb water and nutrients from the soil and it sent to the upper parts of the plant. In roots, most water absorption happens through the root hairs.
