Organisms can be separated by their most basic characteristics into the broadest groups known as Kingdoms.
What are kingdoms?It is a taxonomic group composed of smaller groups called phyla. The classification of living organisms into kingdoms is a way of organizing the diversity of life into manageable categories.
The most widely recognized system of classification is the Five kingdom classification which was given by Robert Whittaker which recognizes kingdoms such as- Monera, Protista, Fungi, Plantae and Animalia.
Each kingdom is further divided into smaller groups based on increasingly specific characteristics until the species level is reached. The system of classification is constantly being refined with the discovery and interrelationship between different organisms.

a biology teacher shows the class pictures taken while using different microscopes. the plant cells have visible chloroplasts, and a sample of human cheek cells shows a nucleus and a cell membrane. what type of microscope was used for these pictures?
If a biology teacher shows the class pictures where plant cells have visible chloroplasts human cheek cells show a nucleus and a cell membrane. then the type of microscope that was used is an optical microscope.
What is an optical microscope?An optical microscope is a device that contains different magnification lens that allows for increasing the size of the image. These lens include ocular and objective lens.
In conclusion, an optical microscope can be used to observe microscopic substructures such as chloroplasts in plant cells or the cell nucleus in human cells, which depend on the magnification of the image (cell nucleus: 1000 X).

A high metabolic demand means that the cell requires a large amount of energy released in the process called cellular respiration. The mitochondria are where most of the energy of the cell is made.
what organelle is critical for endocytosis and exocytosis to occur
Answer:
Endoplasmic Reticulum
Explanation:
The cell membrane, also known as the plasma membrane, is an organelle that is essential for both endocytosis and exocytosis to take place.
Thus, The cell membrane, which encloses the cell and separates its internal contents from the outside environment, is a barrier that is selectively permeable.
The process by which cells absorb materials from their surroundings is known as endocytosis. The cell membrane invaginates and creates a vesicle that encloses the substance being transported into the cell during endocytosis.
The vesicle is subsequently taken inside and moved into the cytoplasm of the cell. In this process, the cell membrane is essential because it helps the endocytic vesicle develop.
Thus, The cell membrane, also known as the plasma membrane, is an organelle that is essential for both endocytosis and exocytosis to take place.

Answer:
They can’t expand or stretch with out a synthesize a new exoskeleton underneath the old one and then sheds or molt the original covering.
An Exoskeleton be a disadvantage for growth and movement because exoskeleton Restricts the growth of the organism due to its rigidity.
what is an Exoskeleton?In contrast to the interior skeleton of a human, an exoskeleton is the external skeleton that supports and protects an animal's body. Some of the larger exoskeletons are referred to as "shells" in common language.
what are the advantages of Exoskeleton?Having a hard covering on the outside in the form of an exoskeleton is a great defense against predatorsit helps to support the body and it's like wearing a portable raincoat that keeps the creature from getting wet or drying outIt also protects the fragile interior organs and muscles of the animal from harmwhat are the disadvantages of Exoskeleton?An exoskeleton provides a significant restriction on growth. Arthropods must exfoliate, shedding their old shell and growing a new one, because their exoskeletons do not grow with them
thus exoskeleton may provide protection to the insect but ristricts the growth of arthropod.

which structures are found in palisade cells and liver cells
Answer:
All cells contain a nucleus and a nuclear envelope and the liver cell is no exception. It has exactly the same control over the cell as the palisade nucleus does. To keep it all together, it is surrounded by a cell membrane.
Explanation:
Since a liver cell is an animal cell, it lacks chloroplast. Below the epidermis of the leaves is a palisade cell. It participates actively in photosynthesis, chloroplasts are present.
What structures are found in liver cells?Liver cells lack a cell wall but do have a nucleus and a cell membrane. It receives blood from two main sources: The Hepatic Portal Vein, which delivers blood from the digestive tract that is nutrient-rich.
The nucleus and nuclear envelope are components of every cell, including liver cells. The cell is under the exact same management that the palisade nucleus is. It is encased in a cell membrane, which serves to keep everything together.
Therefore, as an animal cell, the liver lacks the cell wall, chloroplast, and big vacuole that are often seen in plant cells.

They have used these data to determine the amino acid sequences of these proteins and have applied molecular modeling techniques to predict the three-dimensional structures of the proteins. All contain nearly identical folding regions that may serve to hold lipid membranes in sharp curves. Because this finding has been demonstrated in both yeast and vertebrates (representing organisms that diverged long ago in evolutionary history), it provides evidence of a possible mechanism for the evolution of a subcellular structure.

explain how transport across the plasma membrane is related to the homeostasis of the cell.
Transport across the plasma membrane is fundamental for maintaining an equilibrium state in the cell.
The cells need to carry out different metabolic processes such as reproduction, growth, differentiation, etc.Many of these processes require the presence of certain substances as well as concentration gradients to be performed.Moreover, the cells also need to eliminate waste products that otherwise would be toxic for them.In conclusion, transport across the plasma membrane is fundamental for maintaining an equilibrium state in the cell.
