Answer: Principle of Original Horizontality.
According to the principle of original horizontality all rock layers are horizontal in nature and this is specific to sedimentary rocks. The younger sediments remains in the top layers and older ones remains at the bottom. These sediments accumulate in horizontal and parallel layers and becomes compact to form rocks in the end.
The flowering plants tend to reproduce more in the warmer summer months.

A hydrocarbon consists of four carbon atoms with one double bond. Predict the molecular formula of this compound.
the awnser would be c4h8
(1) modification of genes in body cells
(2) modification of genes in sex cells
(3) increased reproduction among individuals
with identical chromosomes
(4) recombination of genes in cells reproducing
by mitosis
Evolution in sexually reproducing species occurs as a result of modification of genes in sex cells. Genetic variation through mutations and genetic recombination during meiosis leads to offspring that are genetically different from their parents, providing the basis for natural selection and evolution.
In a sexually reproducing species, evolution occurs as a result of modification of genes in sex cells. Sex cells, or gametes, such as sperm and eggs, carry genetic information that is passed on to offspring. Genetic variation can arise through mutations or through the process of genetic recombination during meiosis, resulting in offspring that are genetically different from their parents. This genetic variation provides the raw material for natural selection and evolution.

Correct answer: A). Club
Club fungi are heterotrophic and it can be saprophytes. The enzyme present in the club fungi decompose the leaves, wood and other organic materials. It can be eaten by other fungi and bacteria.
It is distinguished from the other fungi by the presence of a club-shaped organ called as a basidium. Puffballs, mushroom and shelf fungi are the members of this group.
Hence, the correct answer would be option A.
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.

-decreases
-remains constant
The correct answer is remains constant.
The law of conservation of momentum can be stated as in an isolated system when any collision between two bodies takes place then the the total momentum remains constant. This law has been derived from the Newton's law of motion. The collision of body transfers its energy from body A to another body B.
Hence, in this way the total momentum remains constant.
