Nerve Cell Introduction (both parts) Our nervous system is divided into two parts: central nervous system (composed of the brain and spinal cord) and peripheral nervous system (composed of nervous tissue located outside the central nervous system). Understanding the Nervous System: Main Features It is in the central nervous system that our thoughts, emotions, memories are stored and all kinds of sensory stimulation occur.
Bacteria (autotroph) and lion (carnivorous heterotroph) Autotrophs Also known as producer beings, they are those who have the ability to produce their own food. According to the process used to manufacture the food, they can be classified into chemosynthesizers and photosynthesizers.
Cell Nucleus: Important Functions in the Cell Introduction - What is the Cell Nucleus The nucleus is one of the most important organelles in an animal cell. It is composed of a complex structure that performs extremely important functions in the cell. Much of cell activity is controlled by genes, which are located in the cell nucleus.

Corals: Asexual Reproduction Introduction - What it is Unlike in sexual reproduction, in asexual reproduction there is no need for another individual to generate offspring, that is, in this type of reproduction only a single being is capable of generating other genetically identical ones. This occurs through a process of cell division called mitosis.
Acerola: Great Source of Vitamin C Vitamin C functions in the body: · Strengthens the blood capillaries. · It is extremely important in antiallergic treatments. Helps strengthen the immune system. · It is excellent in preventing influenza and infections. It acts on the body as a powerful antioxidant.
Endoplasmic Reticulum: Important Cell Organelle What it is - Definition The Endoplasmic Reticulum is an organelle present within the cells of eukaryotes (presence of cell nucleus and various organelles). Main features: - Formed from plasma membrane invagination; - Formed by tubules and flattened vesicles; - Has connection to the library (nuclear wrap); - RE membranes surround spaces that are separated from the rest of the cell.
Metabolism: Chemical and Physical Processes in the Body What is Metabolism Metabolism is the sum of chemical and physical processes that take place within a living organism. Types Metabolism is divided into catabolism (breakdown of a substance for energy) and anabolism (the body's ability to transform one substance into another for development and repair).
Karyoplasma: rich in organic molecules What it is (definition) Karyoplasma, also known as nucleoplasma, halioplasma or karyolymph, is an aqueous (semi-liquid) solution composed of proteins, nucleotides, RNAs, nucleosides and ions. In this compound are the nucleoli and chromatin dipped.
Nervous System: One of the Homeostasis Controllers What It Is (Meaning): Homeostasis is the relatively stable condition that the body needs to perform its functions properly for the body's balance. Homeostasis: Greek word, whose meaning already defines very well what it is: homeo- = similarity; -stasis = put action, stability.
Animal and Plant Cell: Many Differences Main differences between animal and plant cells: Animal Cell: In the Golgi Complex, the vesicles are stacked. Plant Cell: Golgi Complex vesicles appear isolated. Animal Cell: has centriole. Plant Cell: has no centriole.

Blue Whale: The World's Largest Mammal Introduction Within the classification of vertebrate animals, mammals are the most important. Females of this species have milk-secreting mammary glands, which is an indispensable food for young mammals. Mammal Information and Characteristics Most mammals have hair, some have partially covered body, while others have hair all over their bodies.

Rattlesnake: poisonous and common snake in Brazil What they are Snakes are reptiles belonging to the order Squamata. They are also known as snakes and have as main feature the absence of legs, which lost during the evolutionary process. Main characteristics of snakes: - They have the ability, due to anatomical characteristics, to ingest large prey (whole and without the need to chew them).
Spider: A very feared arachnid by people What they are (definition) and examples Arachnids are organisms that belong to the Arachnida class of the Arthropod phylum. This class includes more than 60,000 species, including: spiders, ticks, scorpions, etc. Main Characteristics of Arachnids Arthropods have a well-developed nervous system and many of them, such as spider and crab, have exoskeleton, ie a hard outer shell.
Example of an ecological pyramid Introduction (what they are) Getting food is the same as getting energy to stay alive and perform the most diverse biological functions. All living things are part of some food chain. Ecological pyramids are representations of the energy flow that happens in all food chains.
Environmental Microbiology: A Major Area of Biology Introduction (what it is) Microbiology is a branch of knowledge in the large area called Biology.
