The key difference between stem and trunk is that the stem usually refers to the main structural axis of a plant while trunk usually refers to the main structural axis of a tree. Stem and trunk are two botanical names sometimes used in a similar sense. Strictly speaking, there is some difference between stem and […]
The key difference between fermentation and respiration is that the fermentation occurs in the absence of oxygen while the respiration needs oxygen. Organisms require energy to perform cellular activities. Hence, they generate energy molecules in the form of ATP. They use different substrates and break down into different forms, and the releasing energy converts into […]
The key difference between allele and locus is that the allele refers to one of the two or more alternative sequences of a gene at a certain locus while the locus refers to a certain location on a chromosome where a gene can be found. In the form of genes, genetic information inherits from parents […]
The key difference between cellulose and starch is that the cellulose is a structural polysaccharide that has beta 1,4 linkages between glucose monomers while the starch is a storage polysaccharide that has alpha 1,4 linkages between glucose monomers. Starch and Cellulose are macromolecules belonging to the same group of carbohydrates. Carbohydrates are one of the […]
The key difference between xylem and phloem is that xylem is the tissue that conducts water and minerals throughout the plant body while phloem is the tissue that conducts sugar (foods) around the plant body. Tracheophytes are the vascular plants that contain a vascular system. The vascular system is a network of plant cells that […]
The key difference between heart rate and pulse rate is based on their definitions. Heart Rate is the rate at which the heart contracts and relaxes. In contrast, Pulse rate is the rate at which the artery expands and contracts when blood passes. Heart rate and pulse rate are often confusing as they are more […]
The key difference between active transport and passive transport is that the active transport moves molecules from low concentration to high concentration against the concentration gradient via a semi-permeable membrane while passive transport moves molecules along the concentration gradient from high concentration to low concentration. Furthermore, Active transport requires energy for molecular movements in contrast […]
染色体和chromati之间的区别的关键d is that a chromosome is a long thread-like form of a DNA molecule while a chromatid is one-half of two identical copies of a replicated chromosome. In fact, two chromatids are joined together by a centromere to form a chromosome. Chromosome and chromatid are closely related structures that […]
The key difference between oestrogen and progesterone is that the oestrogen is the main female sex hormone, which is responsible for the growth of the female reproductive system and secondary sex characteristics while the progesterone is another female sex hormone, which is important for the maintaining and sustaining a pregnancy. Women synthesize several sex hormones including […]
The key difference between ICD and pacemaker is that ICD is an implantable device that sends out a shock when the heart beats way too fast rate while pacemaker is an implantable device that sends out electrical pulses when the heart beats way too slow. ICD (implantable cardioverter defibrillators) and pacemaker are two little implantable […]
