Thylakoids and cristae are respectively structures of?
Thylakoids are structures found in chloroplasts, where photosynthesis takes place. They contain chlorophyll and other pigments that capture light energy for the synthesis of sugars. Cristae are folding of the inner membrane of mitochondria, increasing the surface area for cellular respiration, which produces ATP energy for the cell.
What are the differences between l-carnitine acetyl and l-carnitine tartrate, and how do they impact their effectiveness as supplements?
L-carnitine acetyl and L-carnitine tartrate are two forms of the same compound, but with different chemical structures. L-carnitine acetyl is more easily absorbed by the body, while L-carnitine tartrate is better for improving exercise performance. The effectiveness of each as a supplement depends on the specific health goals and needs of the individual.

Structures that are similar are called?
Structures that are similar are called analogous structures. These structures may serve similar functions but have evolved independently in different species.
What between two other structures is?
It is unclear what structures you are referring to. Could you please provide more context or specify which structures you are asking about?
Why did they stop building Japanese castles?
In addition to losing their effectiveness as defensive structures with advances in technology, as civil strife within the country declined, so did the necessity of such structures.
What are the benefits of using plywood decking for outdoor structures?
The benefits of using plywood decking for outdoor structures include durability, strength, resistance to moisture and weather damage, ease of installation, and cost-effectiveness.
What are the small hair like things that are on plant roots?
Root hairs - Absorptive unicellular extensions of epidermal cells of a root. These tiny, hair-like structures function as the major site of water and mineral uptake. Root hairs are extremely delicate and subject to desiccation. Root hairs are easily destroyed in transplanting.
What are the four properties considered when choosing materials to use in structures?
When choosing materials for structures, it is important to consider strength, durability, cost-effectiveness, and ease of construction. Strength ensures the material can withstand various loads, while durability ensures the material can withstand environmental conditions over time. Cost-effectiveness is important to stay within budget, and ease of construction impacts the feasibility of using the material in the project.
What effect has petrissage on the hair and scalp?
This is helpful for the help in strengthening the structures by stimulating the deep layers of tissue and help in increasing the supply of blood to the area.
When did feudalism in medieval time it eventually breakdown and lose its effectiveness?
Feudalism began to break down in the late medieval period, particularly from the 14th century onwards. Factors contributing to its decline included the rise of centralized monarchies, the growth of trade and towns, and the impact of the Black Death, which significantly reduced the labor force and empowered peasants. By the 15th century, the increasing strength of nation-states and changes in military organization further diminished the feudal system’s effectiveness. Ultimately, this shift laid the groundwork for the emergence of more modern economic and social structures.

Which structures of the small intestines increase the surface area available for absorption?
The absorptive surface area of the small intestine is actually about 250 square meters (almost 2,700 square feet) - the size of a tennis court! There are two structures that allow absorbsion: 1) villi which are folds and 2) microvilli, tiny finger like projections on each villi.
Why to study perfect competition if it does not exist in the real world?
By studying perfect competition, we can learn how much an ideally functioning market system might accomplish and we can compare it to real world market structures.
What is used to strengthen a structures?
Structures can be strengthened using materials such as steel reinforcements, carbon fiber, or reinforced concrete. These materials are added to improve the strength, durability, and load-bearing capacity of the structure. Additionally, techniques like increasing wall thickness, adding bracing elements, or using high-strength materials can also be employed to strengthen structures.
What structures in the human intestine make it 250m squared?
The large surface area of the human intestine, approximately 250 square meters, is primarily due to three key structures: the circular folds (plicae circulares), villi, and microvilli. Circular folds increase the surface area significantly by creating folds within the intestinal lining. Villi are small, finger-like projections that extend from the folds, further enhancing absorption. Microvilli, tiny hair-like structures on the surface of each epithelial cell, create a brush border that maximizes the absorptive area, allowing for efficient nutrient absorption.
What is the absorptive surface area of the small intestine?
The absorptive surface area of the small intestine is actually about 250 square meters (almost 2,700 square feet) – the size of a tennis court! How is this possible? The small intestine has three features which allow it to have such a huge absorptive surface area packed into a relatively small space:1. Mucosal folds: The inner surface of the small intestine is not flat, but thrown into circular folds. This not only increases the surface area, but helps regulate the flow of digested food through your intestine.2. Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through.3. Microvilli: The cells on the villi are packed full of tiny hair like structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
