Explanation:
Muscle tissue has the ability to contract and relax due to its property of excitability, which allows muscle cells to respond to stimuli and generate electrical signals. This contraction and relaxation are initiated by action potentials and the release of ATP (adenosine triphosphate) in muscle fibers. After contraction, relaxation occurs by removing calcium ions from the muscle fibers.
The ability of muscle tissue to contract and relax is due to its unique property called excitability. Excitability refers to the ability of muscle cells, also called muscle fibers, to respond to stimuli and generate electrical signals. These electrical signals, known as action potentials, are responsible for initiating the contraction and relaxation of muscle tissue.
When a muscle fiber receives a stimulus, it releases calcium ions and generates an action potential. This action potential spreads along the muscle fiber, resulting in the release of stored energy in the form of ATP (adenosine triphosphate). This energy is used by the muscle fibers to convert chemical energy into mechanical energy, leading to muscle contraction.
After contraction, muscle fibers need to relax. This relaxation process involves the removal of calcium ions from the muscle fibers, allowing them to return to their resting state. The ability of muscle tissue to contract and relax enables it to perform essential functions such as movement, posture maintenance, and organ control.

The key property of muscle tissue that allows it to contract and relax is contractility. Muscles also have the properties of extensibility and elasticity which allow them to stretch or extend and return to their original length respectively. The functionality of these properties is seen across three types of muscle tissue: skeletal, cardiac, and smooth.
The property of muscle tissue that gives it the ability to contract and relax is known as contractility. This property allows muscle tissues to pull on their attachment points and shorten with force. In addition, muscles have two other notable properties, specifically, extensibility and elasticity. Extensibility enables a muscle to extend or stretch, while elasticity allows the muscle to return to its original length after it has contracted or stretched. These three properties work in combination to facilitate the smooth movement of muscles.
Three types of muscle tissue exist in the human body: skeletal, cardiac, and smooth muscle. Skeletal muscle is primarily responsible for voluntary movements, cardiac muscle causes the heart to beat, and smooth muscle is involved in involuntary movements such as the contraction of our pupils in bright light or the peristaltic movements in our intestines.

Answer:
the answer is C
Explanation:
b. Recycling paper can lead to 74% less air pollution.
c. Paper recycling can save on the use of water resources.
d. Recycling paper can lead to 35% less water pollution.
The statement presented above that is not true about paper recycling is; A) Recycling one ton of newspaper can save 100 trees.
Paper recycling are the processes of reprocessing waste paper such as old newspapers and magazines into new paper products for reuse. Apart from saving trees from being cut, paper recycling has many other significant benefits such as reducing water and air pollution, saving on the use of water resources and energy. For every ton (200 pounds) of newspaper that is recycled, 17 trees are saved.
The false statement here is that; "recycling paper can lead to 35% less water pollution." The idea of recycling a huge environmental conservation effort.
The term recycling has to do with the process of using a material for the same or another purpose rather than simply disposing the material after it has been used. The idea of recycling a huge environmental conservation effort.
The false statement here is that; "recycling paper can lead to 35% less water pollution."

B)Mitosis
C)Fertilization
D)Differentiation
The inability of sperm cells to move normally could prevent the production of offspring by interfering with fertilization, which is present in Option C, as fertilization is the fusion of the male and female pronuclei to form a zygote.
In sexual reproduction, fertilization is important as it is the fusion of the sperm and the ovum and forms a unique individual with a unique genetic makeup and allows for genetic diversity, which increases the rate of survival in the case of any genetic disease. Fertilization aids in adaptation because sexual reproduction results in a new, distinct type of genetic recombination that may be better suited to the changing environment.
Hence, the inability of sperm cells to move normally could prevent the production of offspring by interfering with fertilization, which is present in Option C, as fertilization is the fusion of the male and female pronuclei to form a zygote.
