Rods and Cones are the photoreceptors, useful in providing vision to the eyes. Rods provide vision during dim light or night also known as scotopic vision, whereas cones provide vision during day time or at bright light also known as photopic vision. Secondly, rods do not support the colour vision, but cones are capable of colour vision, with high spatial acuity — the level of the light where both the types of work, is called a mesopic vision. Eyes are one of the primary sense organs found … [Read more...]
Difference Between Micro-Evolution Vs Macro-Evolution
Micro-evolution refers to the alteration in a gene pool of the population over time, resulting in small changes of an organism in the same species. On the other hand, Macro-evolution refers to the alteration in organisms, and these changes gradually give rise to completely new species, which is different from their ancestors. The genetic change in the scale of descent over time or heritable change in a population of an organism; brought up by the process like genetic drift, mutations, gene … [Read more...]
Difference Between Renewable and Non-Renewable Resources
The main points of distinction between Renewable and Non-Renewable resources are the amount at which they are used, and the rate of exhaustion, their costs, effects on the environment. Resources can be defined as available means or stock from which the individual is benefited, while natural resources are such resources which are available naturally on Earth, these can be biotic (living things) like plants, animals (their products), birds, marine organisms, mineral fuels (oil/ petroleum, coal) … [Read more...]
Difference Between Vascular and Non-Vascular Plants
Vascular plants or tracheophytes are known for their proper organization of the systems, and bearing flowers, green leaves, stems, roots, woods, and branches, on the contrary, Non-vascular plants or bryophytes do not perfectly fit with these features. Examples of Conifers, Ferns, flowering, and non-flowering plants are examples of vascular plants, while Mosses, Liverworts, and Hornworts are examples of non-vascular plants. But most importantly the difference lies in the presence of the … [Read more...]
Difference Between Point and Frameshift Mutations
The changes in the single base or nucleotide in the nucleotide sequence and thus changing its complementary base also it is called as point mutations, while when there are insertions or deletions of more than one base pair in the nucleotide sequence it is known as frameshift mutations. Mutations can be defined as any kind of change in the nucleotide sequence or genetic code, which altering the gene structure as well as the amino acids and the proteins too. These mutations occur in the DNA … [Read more...]
Difference Between Oestrogen (Estrogen) and Progesterone
Oestrogen or estrogen is the female steroid hormone known for the development of the female reproductive system, while progesterone is also another type of female steroid hormone known for releasing corpus luteum and supports the pregnancy. These are the types of steroids hormones and are categorized under two category which are corticosteroids and sex steroids. Among which the mineralocorticoids and glucocorticoids are the are the types corticosteroids, while oestrogen or estrogen, … [Read more...]
Difference Between Bacteria and Fungi
Bacteria are said to occupy the large domain of the prokaryotic cell, while the virus is known as minor infection causing agent. Secondly, bacteria reproduce by themselves through asexual method whereas virus needs a host cell to replicate as they lack cellular machinery but consist of DNA and RNA. When people fall ill, the first thing that struck to their mind is about any contamination, related to bacteria, fungi or virus. This routine is typical in all age of peoples, as these terms like … [Read more...]
Difference Between Systolic and Diastolic Blood Pressures
When the muscles of the heart contracts it is known as systolic, whereas when the heart muscles relax it is known as diastolic. At the time of systole the blood pressure increases, but at the time of diastole, the blood pressure decreases. These are the two types of blood pressure, controlled by the beating of the one's heart. The heart is the organ which provides oxygenated blood to all tissues, organs and other body parts. For pumping the blood the heart contracts and relax continuously and … [Read more...]
Difference Between Parenchyma, Collenchyma and Sclerenchyma Cells
Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant. Likewise the humans, who have bones to support their body structure, plants also have certain specialized tissues which help them, by providing … [Read more...]
Difference Between Hibernation and Aestivation (Estivation)
The state of inactivity and a low metabolic process performed by the animals during the winters is known as Hibernation. It is also known as winter sleep. On the contrary, when animals take rest in shady and moist place during summer, it is called Aestivation or Estivation. Aestivation is also known as summer sleep. The importance of these sleep is mainly related to the conservation of energy of one's body, survival during the extremes temperature, scarcity of food and water, etc. These sleep … [Read more...]
