Animal Kingdom- Definition, Characteristics, Phyla, Examples

Animal Kingdom, sometimes referred to as Kingdom Animalia, is a broad category of species that have a few traits in common. Animals are eukaryotic, multicellular organisms that are usually heterotrophic—that is, they get their nourishment by eating other living things. They are able to engage in complicated activities and interactions with their surroundings because they […]

Anaphase in Mitosis and Meiosis (Anaphase I, II)

Biology / Neha Khadka

Anaphase in Mitosis and Meiosis is a critical phase where the chromosomes are separated and pulled toward opposite poles of the cell. Despite the similarity in this process across cell divisions, there are distinct differences in how it occurs in mitosis versus meiosis. The crucial stage of Anaphase in Meiosis and Mitosis occurs in both

Blood Cells- Definition and Types with Structure and Functions

Blood Pressure: Definition, Measurement, Mechanism

Biology / Prastu Regmi

Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps it throughout the body. It is a vital indicator used to determine cardiovascular health. It is usually measured in millimeters of mercury (mmHg) and expressed as two numbers: systolic pressure and diastolic pressure. The systolic pressure (the higher

Animal Cell: Structure, Parts, Functions, Labeled Diagram

Biology / Krisha Silwal

A eukaryotic cell without a cell wall that is surrounded by the plasma membrane is called an Animal cell. The plasma membrane encloses all of the cell’s organelles, including the nucleus. Plant cells contain a cell wall, in contrast to animal cells that have not. It can be anywhere in size from a few millimeters

Angiosperms- Characteristics, Morphology, Classification, Uses

Biology / Sareena Basnet

Angiosperms, also known as flowering plants, are a group of plants that have seeds and flowers inside of fruits. They can be distinguished from gymnosperms by this characteristic, as the latter do not have seeds enclosed in fruit. Encompassing a wide variety of species found in almost every habitat on Earth, they are the largest

Analogous Structures: Definition, 4 Examples, Significances

Biology / Upshan

What is Analogous Structures ? As opposed to homologous structures, which originate from a common ancestral feature, analogue features are characteristics of distinct species that have developed in response to comparable environmental challenges and are similar in function but not always in structure. Comparable biological structures are those seen in various species that serve comparable

Analytical Balance- Definition, Principle, Parts, Types, Examples

Biology / Krisha Silwal

A high-precision tool for measuring mass precisely, analytical balances usually measure mass to within 0.0001 grams (0.1 mg) or less. For quantitative chemical analysis, these balances are frequently utilized in scientific settings. An analytical balance is a very precise laboratory balance used to precisely calculate the mass of an object. The items could be powders,

Anisocytosis: Types, Causes, Symptoms, Diagnosis

Biology / Sayuja Koirala

Anisocytosis is a disease in which red blood cells vary significantly in size. It is frequently discovered during a complete blood count (CBC) when the red cell distribution width (RDW) is increased. This is not a disease, but rather a symptom of several underlying disorders. It can indicate a variety of hematological and systemic diseases.

Amino Acids- Properties, Structure, Classification, Functions

Biology / Krisha Silwal

As the building blocks of proteins, amino acids are essential to many biological processes. From a structural standpoint,it is usually made up of an amino group, a variable group, a carbon atom, a hydrogen atom, and a carboxyl group. It can be divided into four groups based on the variable group: nonpolar, polar, negatively charged,
