What difference between ocean and sea?
The word Ocean refers to one of the Earth's four distinct large bodies of water. The Atlantic, Pacific, Indian and Arctic Oceans. It can mean all the water that covers the Planet, and derives from the Greek Okeanos. The word sea can mean a vast body of water, but generally refers to bodies of salt water smaller than the great oceans that are generally marked off by land boundaries or enclosed by land. (The North Sea or Caspian Sea for example
What is special about an abyssal plain?
Abyssal plains cover about 50% of the surface area on Earth and usually positioned between continents and midocean ridges. They are typically at least 3000m deep and represent some of the flatest, smoothest, and least explored landscapes on Earth.
What are the similarities and differences between the cell and ecosystem?
Similarities: Both cell and ecosystem are organized systems with various components that work together to maintain life. They both rely on interactions between different parts to function effectively.
Differences: A cell is the basic structural and functional unit of living organisms, while an ecosystem is a complex network of organisms interacting with each other and their physical environments. Cells are microscopic and found within individual organisms, whereas ecosystems are larger-scale systems that encompass multiple organisms and their environment.
What is the differences between bacteria and white blood cells?
1. Bacteria have a single, circular chromosome. White blood cells have many, (more-or-less) linear chromosomes. (Exact number depends on species.)
2. The bacterial chromosome is loose within the cell. In white blood cells (and other eukaryotic cells), the chromosomes are contained within the neucleus.
3. Bacteria do not (generally) contain organelles. (Although some may contain gas vesicles or simple nutrient storage structures.)
4. Bacterial ribosomes are smaller than eukaryotic ribosomes. (70S vs. 80S)
5. Bacteria have a cell wall, white blood cells do not.
6. Depending on the type of bacteria they may or may not photosynthesize (eg. cyanobacteria). White blood cells never photosynthesize.
7. Some bacteria may have cilia and/or flagella.
8. A bacterium is a complete organism all on its own. A white blood cell is part of a much larger organism.
9. Bacteria reproduce via "binary fission" or "budding", white blood cells replicate via mitosis.
What is the difference between a genetically inherited vs a contagious disease?
A genetically inherited disease is passed down from parents to their offspring through genes, while a contagious disease is caused by pathogens such as bacteria or viruses that can be transmitted between individuals through direct or indirect contact. Genetically inherited diseases are not contagious and cannot be spread from person to person, whereas contagious diseases can be easily transmitted between individuals.
What is it that provides connection between the mother and the embryo?
The placenta is the organ that provides connection between the mother and the embryo. It facilitates the exchange of nutrients, gases, and waste products between the mother's and the embryo's circulatory systems during pregnancy.
What is the difference between karyogram and karyotype?
A karyogram is a photograph of an individual's chromosomes arranged in a standard format, while a karyotype is the set of chromosomes found within the nucleus of a eukaryotic cell. In simpler terms, the karyogram is the visual representation of the karyotype.
Change producing differences between organisms?
Genetic mutations result in changes in DNA, leading to variations in organisms. These changes can be beneficial, neutral, or harmful and can influence a species' evolution and adaptation to their environment. Over time, accumulation of genetic differences can lead to speciation and the formation of new species.
Which method uses the density differences of rocks to interpret subsurface structures?
Seismic reflection is the method that uses the density differences of rocks to interpret subsurface structures. It involves sending seismic waves into the ground and measuring the reflections to create a picture of the subsurface geology based on the different densities of rock layers.
What is the difference between a sandblasted rock and rock?
A sand blasted rock is any rock that's sitting in a landscape where sand can be picked up by the wind and blow against the rock.
If there's isn't any sand that can be blown around, you can't get a sand blasted rock.
What is the difference between polymorphism and a mutation?
Polymorphism refers to the existence of different forms of a gene within a population. It contributes to genetic diversity. Mutation, on the other hand, is a change in the DNA sequence that can result in genetic variation. Mutations can lead to new alleles, whereas polymorphism describes the presence of multiple alleles in a population.
How does groundwater recharge?
Groundwater recharge occurs when water from precipitation or surface water infiltrates into the ground through soil and rock layers. This replenishes the underground aquifers, increasing water levels and sustaining groundwater resources. Factors such as soil composition, vegetation cover, and land use practices can all affect the rate of groundwater recharge.
What is the different between the kidney and the groin?
The kidney is a vital organ in the body responsible for filtering blood and producing urine, located in the back of the abdomen. The groin is the area of the body where the thigh meets the abdomen, containing muscles, tendons, and lymph nodes. The kidney is not situated in the groin; they are distinct anatomical structures with different functions.
What is the difference between hotspot volcanoes and volcanoes formed at plate boundaries?
Hotspot volcanoes form over a fixed hotspot in the mantle, resulting in a chain of volcanoes as the tectonic plate moves over it, like the Hawaiian Islands. Volcanoes at plate boundaries are formed by the interaction of tectonic plates, where one plate is forced under another (subduction) or plates move apart (divergence), creating volcanic activity along the boundary, like the Ring of Fire.
Are there differences between major groups of organisms to how fast they respire?
Yes, there are differences in respiration rates among major groups of organisms. For example, mammals generally have higher respiration rates compared to plants or reptiles. This is influenced by factors such as metabolic rate, body size, and environmental conditions.
What is the difference between prokaryotic and eukaryotic cells' DNA?
One main difference is that prokaryotic cells have a single circular chromosome located in the nucleoid region, while eukaryotic cells have multiple linear chromosomes housed inside a membrane-bound nucleus. Additionally, prokaryotic DNA is not associated with histone proteins, unlike eukaryotic DNA which is tightly wrapped around histones.
What is the difference between florigen and phytochrome?
florigen
)its a hormone responsible for inducing flowering in plants directly
)moves from leaves to the apex inducing flowering by phloem mechanism
)no inter conversion from one phase to other
phytochrome
)it is a light absorbing pigment which induces flowering in long day plants
)pigments p660 and p730 absorb red and far red light respectively
)p660absorbs red light and immediately converts into p730 and as p730 absorbs far red light which induces flowering thus flowering is induced in long day plants because p730 is present in day
What are the genetic differences between bacteria cells and human body cells?
One key genetic difference is the presence of a nucleus in human cells, which bacteria lack. Human cells have linear chromosomes enclosed within the nucleus, while bacteria have a single circular chromosome located in the cytoplasm. Additionally, bacteria may have plasmids, small circular DNA molecules that are often absent in human cells.
What the difference of selection and variation?
Selection or 'Natural selection' means that the organisms that are better adapted to their environment are most likely to stay alive and produce offspring, while Variation means that during natural selection, the organism that is better adapted to the environment starts to form more physical features to help it survive (mutations).
For example,
Say that there was a white desert. If there were 2 mice, one species is black while the other is white, white would survive, which would be an example of Natural Selection. Variation is if, say, the mice are slow and can still be easy prey, but later on they mutate into becoming faster, that would be variation.
What is the major difference between adaptive radiation and punctuated equilibrium?
They aren't exactly comparable as punctuated equilibrium is concerned with the evolutionary course of a species while an adaptive radiation generally involves speciation and so is concerned with the evolutionary course of a genus or family. That aside, the major difference is the variation in the rate of evolution: whether evolution is constant or occurring in bursts.
Punctuated equilibrium - A species has a constant phenotype for many generation (stabilizing selection; no evolution) followed by a rapid burst of evolution (directional selection) which is then followed by another long period of stability and so on. Using its name: the equilibrium (no evolution) is punctuated by short but strong bursts of evolution.
Adaptive radiation - A starting species expands into a new environment and begins to adapt to the new conditions, changing relative to the population still in the old habitat. These populations then colonize further habitats, each becoming different from the others, and so on... The "species" continually expands into new habitats, evolves, and eventually speciates producing a radiation of differently adapted species from a single ancestor. For your question, this means that selection is continually acting to make the populations more different from one and other rather than only happening in bursts
What is the difference between accuracy and precision in science?
accuracy refers to how close a measurement is to the true or actual value. precision is a measure of the exactness of a measurement. so if playing darts high precision is like reproduicibility. you can get them all in the same spot. high accuracy would be scattered around the bullseye. if both then it would be close together near the bullseye.
What is the different between a rock and mineral?
A rock is composed of combinations of minerals, each mineral having its own chemical formula and crystalline structure. Minerals are composed of an element or combination of elements. Granite, for instance, is an intrusive igneous rock composed ofthe minerals quartz, feldspar, mica, hornblende, and other combinations or ratios of minerals.
A mineral is a naturally-occurring inorganic (there are some exceptions to this) crystalline solid (though mercury is regarded as a mineral) with a specific chemical composition and a characteristic internal regular geometric arrangement of atoms, sometimes expressed as natural crystal faces.
A rock is an aggregate of one (such as quartzite) or more (such as granite) mineral particles formed through either crystallization of molten magma (igneous rocks), settling of particles (sedimentary rocks), or reheating and pressure applied to pre-existing rocks (metamorphic rocks), with no set chemical composition or atomic structure.
Why is there a difference in body fluid for men and women?
The difference in body fluid composition between men and women is primarily due to hormonal influences. For example, men generally have higher levels of red blood cells and muscle mass, leading to differences in blood volume and distribution of body fluids. Hormones like estrogen and progesterone can also impact fluid retention and distribution in women, especially during menstrual cycles.
What is the difference between an endocrine cell and a target cell?
the endocrine cell has a jelly like substance and so so it drops off it in the blood vessel and so target cells make hormones in the blood vessel to bind into thereceptor on a target cell sometimes a target cell is very close or far away
What is the difference between the reaction with an enzyme and the reaction without an enzyme?
Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur, allowing the reaction to happen more quickly. Without an enzyme, reactions may still occur but at a much slower rate due to the higher activation energy barrier.
