Peristalsis are the waves like contractions that help in moving food along the digestive tract.

The muscles that line your gastrointestinal track automatically contract and relax in a wave-like motion known as peristalsis. Peristalsis, which starts in the throat when you swallow and continues through the esophagus, stomach, and intestines as you digest, is the movement of food through your digestive system.

Through the myenteric plexus, the parasympathetic nervous system (PNS) stimulates peristalsis. The myenteric plexus' afferent (sensory) nerves transmit data to interneurons inside the plexus. Interneurons interact with efferent nerves to cause smooth muscle cells to produce an action potential (spike-wave).

Extracellular fluid, or fluid found outside of cells, makes for one-third of the body's water content. A 40-litre body contains around 15 litres of . Plasma volume averages 3 litres, or 20%, of this 15 litres of extracellular fluid.

Extracellular fluid (ECF) is the fluid that surrounds cells and is present outside of cells within tissues and organs. The ECF can be further divided into two main compartments: interstitial fluid and plasma. Interstitial fluid is the fluid that surrounds the cells and is present in the spaces between cells within tissues, while plasma is the fluid portion of the blood.

The volume of water in the ECF is constantly changing as water moves into and out of cells and is regulated by various mechanisms, including the action of hormones and the kidneys. In general, the total volume of ECF in the human body is approximately one-third of the body's total water content, with approximately 75% of the ECF being interstitial fluid and 25% being plasma.

The exact volume of water in the ECF can vary depending on factors such as age, sex, and body composition. However, on average, the volume of water in the ECF is approximately 14 liters in a typical adult male, with approximately 10.5 liters of interstitial fluid and 3.5 liters of plasma.

Villi are small, finger-like projections that protrude from the lining of the small intestine. They are made up of specialized cells called enterocytes and are an important part of the digestive system.

The function of villi is to increase the surface area of the small intestine, which allows for more efficient absorption of nutrients from food. The villi are covered in even smaller projections called microvilli, which further increase the surface area available for absorption.

As food passes through the small intestine, nutrients such as glucose, amino acids, and fatty acids are absorbed by the enterocytes in the villi and transported into the bloodstream.

Microspore is the male spore known as in angiosperm reproduction.

Micropore are small haploid structures that develop to the male gametophyte,whereas megaspore develop into female gametophyte

The microspore divides by mitosis producing two cells. The first of the cells (the generative cell) is small and is formed inside the second larger cell (the tube cell). The members of each part of the microspores separate from each other. A double-layered wall then develops around each microspore.

These steps occur in sequence and when complete, the microspores have become pollen grains. Microspore embryogenesis is said used in biotechnology to produce double haploid plants, which are immediately fixed as homozygous for each locus in only one generation. The haploid microspore is then stressed to trigger the embryogenesis pathway and the resulting haploid embryo then doubles its genome spontaneously. Without this double haploid situation, there are several breeding methods of the generations of selection to produce a pure homozygous line.

Answer:

During cellular respiration, glucose becomes more oxidized as it is broken down and releases energy.

Explanation:

During cellular respiration, glucose undergoes a process of oxidation. In other words, it becomes more oxidized as it is broken down into smaller molecules and releases energy.

Oxidation is a chemical reaction in which a molecule loses electrons, making it more positively charged. During cellular respiration, electrons are stripped from glucose and transferred to oxygen, which combines with hydrogen ions to form water. This transfer of electrons results in the conversion of glucose into smaller, more highly oxidized molecules, such as carbon dioxide and water.

The enzyme acetylcholinesterase causes acetylcholine to decompose.

The correct answer is C. Decompose.

Acetylcholinesterase (AChE) is an enzyme that breaks down the neurotransmitter acetylcholine (ACh) into its two components, acetic acid and choline.

ACh is a neurotransmitter that is released by nerve cells and binds to receptors on the muscle cells, causing muscle contraction. However, the continuous binding of ACh to the receptors can lead to overstimulation of the muscle cells, which can cause prolonged muscle contraction and potentially dangerous effects.

The action of AChE is to terminate the action of ACh by catalyzing its hydrolysis into acetic acid and choline.

This process is essential for regulating the concentration of ACh in the synaptic cleft, which is the small gap between the nerve terminal and the muscle fiber. Thus, the enzyme acetylcholinesterase causes acetylcholine to decompose.
