What are the differences between Darwin's and lamarcks theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
What is potential step from 1 potential to o potential?
When there is a potential difference between two points, such as from 1 potential to 0 potential, it means that there is a voltage drop of 1 unit in the direction from higher potential to lower potential. This difference in potential creates an electric field that can drive the flow of electric charge.
What is the difference between a microbe and a fungus?
A microbe is a prokaryotic type of cell, which means it lacks a nucleus and other organelles, and is a single-celled organism. Fungi are multi-cellular, and are eukaryotic, meaning they have a nucleus, and various organelles are contained within their cell membrane.
What are the difference between gaseous cycle and sedimentary cycle?
Biogeochemical cycles are basically of two types:
a) Gaseous cycles like carbon (as carbon dioxide), oxygen, nitrogen, etc.
b) Sedimentary cycles like sulphur, phosphorus, etc.
In gaseous cycles, the elements have a main reservoir in the gaseous phase, and the reservoir pool is the atmosphere or water. The biogenetic materials involved in circulation pass through a gaseous phase before completing the cycle.
In sedimentary cycles, the elements main reservoir pool is lithosphere and the biogenetic materials involved in circulation are non-gaseous. The sedimentary cycles are usually very slow as the elements may get locked up in rocks and go out of circulation for long periods.
What is the difference between virulent phage and prophage?
temperate refers to the life cycle some phages are able to perform. A temperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium.
The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).
So they are both the same in that they both require a host cell to reproduce. They both can have lytic lifecycles but only the temperate phage can "hitch a ride" in the host cell by integrating into the genome.
What is the difference between Flora and herbarium?
flora means pertaining to plants and botany life.
herbarium means plant species that are preserved to plant them again. this can mean the plant itself or plant parts.
Read both links below for a better explanation for the differences between the two.
What is the difference between ascomycetes and zygomycetes?
Ascomycetes produce their spores in sac-like structures called asci, while zygomycetes produce their spores in sporangia. Additionally, ascomycetes often have a more complex structure with septate hyphae, while zygomycetes typically have a simpler structure with coenocytic hyphae.
What is the difference between a deep borehole and a shallow borehole?
A deep borehole is drilled much deeper into the ground compared to a shallow borehole. Deep boreholes are typically used for extracting resources such as water, oil, or gas from deep underground reservoirs, while shallow boreholes are often used for environmental monitoring, water wells, or geotechnical purposes at shallower depths.
What is difference between File name and file extension?
A file name is the main name given to a file, such as document.docx. The file extension, represented by the characters after the dot, indicates the type of file and helps the operating system identify which software to use to open the file. For example, in document.docx, ".docx" is the file extension indicating that it is a Microsoft Word document.
How do evolution and microevolution differ?
Miroevolution is the change in allele frequency overtime in populations of organisms not leading to speciation; below the taxa level. Macroevolution is speciation.
This terminology is not favored by many biologists because there is some implied difference in processes. That is to get from micro to macro. Actually evolution long enough is macro. So, many biologist prefer the terms.
Evolution
Speciation
instead of micro and macro
What is the difference between Nitrosomonas and Nitrobacter?
Nitrosomonas is a genus of bacteria that convert ammonia to nitrite in the nitrogen cycle, while Nitrobacter is a genus that convert nitrite to nitrate. They both play key roles in the process of nitrification, which is essential for the conversion of ammonia into a less toxic form in the environment.
What is the different in male and female?
Among Peafowl, a male is a Peacock, and a female is a Peahen. This is a sexual and nominative difference. The cock is flamboyantly plumed; the hen is less so. There is usually a size difference as well.
What is the difference between communications satellite and global positioning system?
A communications satellite is used to transmit and receive signals for communication purposes, such as phone calls and internet data. On the other hand, the Global Positioning System (GPS) is a network of satellites that provide location and time information to GPS receivers on Earth, enabling navigation and mapping services. In summary, communications satellites facilitate communication, while GPS satellites provide location information.
What is the difference between snow and rain?
There are some clouds that based on appearance are most likely to produce rain (low and very dark in color, or very vertically developed cumulus), but much of our midlatitudeprecipitation comes from stratiform clouds that may produce either rain or snow.
Most of our rain actually forms as ice in the cloud layer and melts on the way down, so it is actually melted snow. Much depends on the temperature of the atmosphere between the clouds and the ground.
As I understand it, dark color tends to indicate higher liquid water content rather than ice, and low means warmer temps, which is why I'd cautiously say that low dark clouds are more likely to be rain.
An awful lot of the time, the look of the clouds probably can't tell you whether to expect snow or rain unless you're a seasoned expert. You can try to judge by what the temperatures outside seem like, and by estimating the environmental lapse rate (the change in temperature with altitude).
There is still quite a debate about this; some people would swear that rain clouds and snow clouds are different, and say they can see in the clouds when it looks like snow.
Tropical rain, of course, is more likely to form as water in the first place - but in tropical regions you're not wondering whether it'll be rain or snow!
A quick check of any meteorology or physical geography text should allow you to read about the two major ways precipitation forms in clouds: the collision-coalescence process (only gives rain) or the Bergeron Ice-Crystal process (could give rain or snow).
What percent of oxygen do mouth to mouth ventilation provide?
Approximately 10-15% oxygen is left in expelled air. it's plenty enough for mouth to mouth ventilation.
What is the Difference between brain fingerprinting and mapping?
A brain fingerprint is the unique alpha and beta waves the brain sends out as every brain is unique to the person but if your GW Bush that will not apply as they will be no activity to record.
the mapping is the brain map that locates the areas of the brain and its activity in the form of a map
What is the difference between man breasts and women breasts?
Male breasts tend to have less glandular tissue and are generally smaller in size compared to female breasts. Female breasts are typically larger and contain more glandular and fatty tissue due to their role in breastfeeding. This difference is primarily due to hormonal influences during puberty and beyond.
What is the difference between glacier water and geyser water?
Glacier water forms from melted snowfall. Geyser water is groundwater that reaches heated rock underground and is thrown back to the surface when some of it turns to steam.
(Both Crystal Geyser and Glacier are trademark names for drinking water.)
What is the difference between maria and terrae?
The lighter parts on the Moon are called terrae, or highlands. They are higher than the maria and include several high mountain ranges. The rock that makes up the highlands is lighter in color and crystallized more slowly than the maria. The rock looks light because it reflects more of the Sun's light.
What is the most important structural difference between algae and euglena?
One of the most important structural differences between algae and euglena is that euglena possesses a flagellum, which allows it to move independently, while most algae lack this structure and rely on water currents for movement. Additionally, euglena have a distinct eye spot called a stigma, which helps them detect light, whereas this feature is not present in most algae.
When is bleached paperboard used?
Bleached paperboard is commonly used for packaging applications where a white, clean, and bright appearance is desired, such as in high-end food packaging, cosmetics packaging, pharmaceutical packaging, and specialty product packaging. Its ability to showcase vibrant colors and graphics makes it a popular choice for products that require an attractive and visually appealing presentation.
What is preprinted linerboard used for?

What is the major differences between ciliates and amoeboids?
Ciliates have hair-like structures called cilia that they use for movement and feeding, while amoeboids move and feed by forming pseudopods, extensions of their cell membrane. Ciliates typically have a more complex internal structure, including a defined nucleus and specialized organelles, compared to the simpler structure of amoeboids.
What is the difference between asexual and reproduction?
Asexual refers to a type of reproduction where offspring are produced from a single parent organism, without the fusion of gametes. Reproduction is the process by which organisms produce offspring, either sexually (involving the fusion of gametes) or asexually.
