Answer:
The correct answer is: fat in the small intestine.
Explanation:
Cholecystokinin, abbreviated to CCK, is a hormone produced in the small intestine that participates in digestion. Its secretion is stimulated by fatty acids in the small intestine (more specifically, in the duodenum) and by the introduction of hydrochloric acid.
Cholecystokinin has the functions to 1) contract the gallbladder so it releases the stored bile into the intestine, and 2) stimulate the secretion of pancreatic juice, which induces satiety.
Cholecystokinin's secretion is primarily triggered by fatty acids and specific amino acids in the small intestine, aiding in their digestion through the release of bile from the gallbladder and enzymes from the pancreas.
The secretion of cholecystokinin from the intestinal wall is mainly stimulated by the presence of fatty acids and certain amino acids in the small intestine's duodenum. Cholecystokinin is a vital hormone that aids in digestion. When fatty acids or certain specific amino acids, such as phenylalanine or tryptophan, enter the duodenum, they trigger the release of this hormone. This hormone then assists in the digestion of these substances by stimulating the gallbladder to release bile and the pancreas to release pancreatic enzymes.

In thanks to the cell wall, the appearance of a plant cell does not change when water is plentiful and is therefore normal.
A cell wall is a structure on the outskirts of most plantcells. The density of the wall can change from time to time, but this wall is often rigid. This cell wall functions to provide the cell with protection and structural support, as well as help it withstand mechanical pressures.
The cell wall helps the cell in withstanding a form of mechanical pressure known as turgor pressure exerted by the vacuole when the plant absorbs a great amount of water. In this way, the cell wall helps in withstanding water pressures in hypotonic solutions. In addition, it also prevents the shrinkage of the cell in hypertonic solutions from exceeding a certain limit.

Biodiversity provide clean air, fresh water, medicines and food security which is also limit to disease and stabilize the climate.
Biodiversity or biological diversity is defined as the variety and variability of life on Earth as a measure of variation at the genetic, species and ecosystem levels. It is described as the great diversity of life on Earth which can be used to refer to all the species in a particular area or ecosystem. Biodiversity is means to every living thing, including plants, bacteria, animals and humans.
The three levels of biodiversity are as follows:
Thus, the Biodiversity provide clean air, fresh water, medicines and food security which is also limit to disease and stabilize the climate.

1. Ecological stability
Each species performs a particular function within an ecosystem. They can capture and store energy, produce organic material, decompose organic material, help to cycle water and nutrients throughout the ecosystem, control erosion or pests, fix atmospheric gases, or help regulate climate.
Ecosystems provide support of production and services without which humans could not survive. These include soil fertility, pollinators of plants, predators, decomposition of wastes, purification of the air and water, stabilisation and moderation of the climate, decrease of flooding, drought and other environmental disasters.
Research show that the more diverse an ecosystem the better it can withstand environmental stress and the more productive it is. The loss of a species thus decreases the ability of the system to maintain itself or to recover in case of damage. There are very complex mechanisms underlying these ecological effects.
2. Economic benefits to humans
For all humans, biodiversity is first a resource for daily life. Such 'crop diversity' is also called agrobiodiversity.
Most people see biodiversity as a reservoir of resources to be drawn upon for the manufacture of food, pharmaceutical, and cosmetic products. Thus resource shortages may be related to the erosion of the biodiversity.
Some of the important economic commodities that biodiversity supplies to humankind are:
- FOOD : crops, livestock, forestry, and fish
- MEDICATION: Wild plant species have been used for medicinal purposes since before the beginning of recorded history. For example, quinine (Used to treat malaria) comes from the bark of the Amazonian tree Cinchona tree; digitalis from the Foxglove plant (chronic heart trouble), and morphine from the Poppy plant (pain relief).
According the National Cancer Institute of the USA, over 70 % of the promising anti-cancer drugs come from plants in the tropical rainforests. Animal may also play a role, in particular in research. It is estimated that of the 250,000 known plant species, only 5,000 have been researched for possible medical applications.
- INDUSTRY: fibres for clothing, wood for shelter and warmth. Biodiversity may be a source of energy (such as biomass). Other industrial products are oils, lubricants, perfumes, fragrances, dyes, paper, waxes, rubber, latexes, resins, poisons and cork can all be derived from various plant species. Supplies from animal origin are wool, silk, fur, leather, lubricants, waxes. Animals may also be used as a mode of transportation.
- TOURISM & RECREATION: biodiversity is a source of economical wealth for many areas, such as many parks and forests, where wild nature and animals are a source of beauty and joy for many people. Ecotourism in particular, is a growing outdoor recreational activity.
3. Ethical reasons
The role of biodiversity is to be a mirror of our relationships with the other living species, an ethical view with rights, duties, and education. If humans consider species have a right to exist, they cannot cause voluntarily their extinction. Besides, biodiversity is also part of many cultures’ spiritual heritage.
Connectivetissue is further classified as loose connective tissue, dense connective tissue, as well as specialized connective tissue.
Tissue that supports, protects, and structures the body's other tissues and organs.
Connective tissue also stores fat, aids in the movement of nutrients and other substances between tissues and organs, and aids in the repair of damaged tissue. Cells, fibers, and a gel-like substance comprise connective tissue.
Connective tissue is basically characterized into three types: loose connective tissue, dense connective tissue, and specialized connective tissue.
Connective tissues connect structures, provide a framework and support for organs and the body as a whole, storefat, transport substances, protect against disease, and aid in tissue repair. They can be found all over the body.
Thus, these are the three basic types of connectivetissue.

Answer:
This syndrome is caused by the deformity or absence of the X chromosome.
Explanation:
The X chromosome is the one that women contributes in the process of fertilization. In this syndrome the X chromosome is defective or absent.
Girls born with this problem have different alterations that can cause a disorder in musculoeskeletal development or also the absence of their internal genital characters.
