evolution, THEORY in biology postulating that the various TYPES of plants, animals, and other living things on EARTH have their origin in other preexisting types and that the distinguishable differences are due to modifications in SUCCESSIVE generations. The theory of evolution is one of the fundamental keystones of modern biological theory.Explanation:MARK ME BRAINLIST

The human body is a SINGLE STRUCTURE but it is made up of billions of SMALLER structures of four major kinds: cells, tissues, ORGANS, and systems. An organ is an organization of SEVERAL different kinds of tissues so arranged that together they can perform a special function.

scles are the MUSCLES PRESENT in your BODY.

A unicellular ORGANISM,ALSO known as a singled-celled organism,is an organism that consist of a single cell,unlike a multicellular organism that consists of multiple CELLS unicellular organisms fall into TWO general categories:prokarvotic organisms and eukaryotic organisms

Electricity is the flow of electrical power or charge. ... The ENERGY sources we use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable or non-renewable. Electricity is a basic part of NATURE and it is one of our most widely used forms of energy.sorry for this and thanks for points have a GREAT day

Chromosomes can be CLASSIFIED on the BASIS of the position of the centromere. These TYPES are METACENTRIC, sub-metacentric, telocentric, and acrocentric.

the TONGUE curls into a spoon for SCOOPING the water up, or a tube for sucking it up. Cats for some reason curl their tongue backwards, but it still makes a little FLESHY spoon.Animals like us who have mobile LIPS, of course, purse the lips into a tube.

To measure blood pressure, your doctor uses an instrument call a SPHYGMOMANOMETER, which is more often REFERRED to as a blood pressure CUFF. The cuff is wrapped around your upper arm and inflated to stop the FLOW of blood in your ARTERY.

In response to RHIZOBIUM infection, host cells synthesize several new components (early nodulins) that MODIFY the PROPERTIES of the cell wall and EXTRACELLULAR matrix. Root nodule extensins are a legume-specific family of hydroxyproline-rich glycoproteins targeted into the lumen of the infection thread.

Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). HERBIVORES then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.The processDuring photosynthesis, plants take in carbon dioxide (CO2) and WATER (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen BACK into the air, and stores energy within the glucose molecules.ChlorophyllInside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.Light-dependent reactions vs. light-independent reactionsWhile there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions. The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH. The light-independent stage, also known as the Calvin Cycle, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction. During this stage, energy from the ATP and NADPH molecules is used to assemble CARBOHYDRATE molecules, like glucose, from carbon dioxide. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide PHOSPHATE (NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells.go dhum j

esult for the explanation causes and symptoms of palpitations, hypertension, heart attack and cardiac arrest Most cardiac arrests OCCUR when a diseased heart's electrical system malfunctions. This malfunction causes an abnormal heart rhythm such as VENTRICULAR tachycardia or ventricular FIBRILLATION. Some cardiac arrests are also caused by extreme slowing of the heart's rhythm (BRADYCARDIA). Heart conditions that can lead to sudden cardiac arrest Coronary artery disease. ... Heart attack. ...

Budding is a TYPE of asexual reproduction in which a new organism DEVELOPS from an OUTGROWTH or bud DUE to cell division at ONE particular site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals. example:- hydra and yeast.Photosynthesis is a process by which green plants make their own food by converting solar energy into chemical energy into chemical energy.

When the warm water hits the yeast, it REACTIVATES it and “wakes it up.” Then it begins to eat and multiply. The yeast organism feeds on the simple sugars FOUND in flour. As they feed, they release CHEMICALS and gases LIKE carbon dioxide and ethanol, along with energy and FLAVOR molecules.
