a friable, light-coloured, sedimentary rock with a diatom content of at least 50%, however, in the Quaternary science literature diatomite is commonly used as a description of a sediment type that contains a "large" quantity of diatom frustules without a precise description of diatom abundance....
Some lichens lay upon the black rocks; some microscopic plants, rudimentary diatomas, a kind of cells placed between two quartz shells; long purple and scarlet weed, supported on little swimming bladders, which the breaking of the waves brought to the shore. View in context A few minutes lat...
(a) Thediatomis composed of an epitheca and hypotheca that fit together like a petri dish. ... A cross section of the diatom reveals that the pores present on the external valve face penetrate to the internal face. What is the purpose of frustules? This overlapping allows for some intern...
What is the difference between schizophrenia and schizoaffective disorder? What is the difference between appendix and annexure? What is the difference between a desmid and a diatom ? What is the difference between callus and galls? What is the difference between genome sequencing and DNA sequenci...
A life cycle are processes and transitions that an organism goes over while living. The life cycle will repeat itself or continue in a circle for every generation.Answer and Explanation: Stage one: egg Fertilized eggs are laid by frogs. That is where young frogs emerge. The eggs develop ...
What is a standard error? (And how should we compute it?) I review the definition of a standard error from a frequentist perspective, including both exact analysis and asymptotic analysis. Using the linear model for illustration, I discuss the model-based, design-based, and sampling-based ...
So how did diatoms survive if zinc is so scarce?Well, recently researchers discovered that a specific type of diatom makes a different enzyme that serves the same purpose.But this enzyme doesn't contain zinc.Instead this new enzyme incorporates another trace metal, cadmium.Kelly, you've got a...
Grass is another example of a photoautotroph, as it uses sunlight to create sugars. For instance, wild grasses commonly grow in the Rocky Mountains. Herbivores such as mule deer feed on the grasses. Then, carnivores like mountain lions consume the deer. There are many types of autotrophic ...
A faucet is a specific type of valve designed for controlling the release of water in settings like kitchens and bathrooms, while a valve is a broader device used to regulate the flow of any fluid or gas in pipes.
