Answer:
A lysis buffer is a buffer solution used for the purpose of breaking open cells for use in molecular biology experiments that analyze the labile macromolecules of the cells (e.g. western blot for protein, or for DNA extraction).
Explanation:
I think the correct answer from the choices listed above is option A. It is in the liver that ammonia is <span>converted to the less toxic compound urea. Most of the wastes products from the processes in our body goes to the liver. It serves as a filter in our body. Hope this answers the question.</span>
Answer:
“Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use
Explanation:
<h2>Cycads and Palm</h2>
Explanation:
The resemblance between cycads and palm trees is only superficial
- Cycads are basically woody plants which have roots, a stem, leaves and reproductive structures known as cones
- The main roots of cycads are thickened and fleshy and as they may have storage capacities they are often termed tuberous
- Along with the fleshy stem they may have contractile properties which serve to regulate the level of the stem in the ground
- Specialized, upright-growing, branched roots, known as coralloid roots, are also produced by all species of Cycads
- The stems of cycads may be completely subterranean or emerge from the ground and be trunk-like
- The leaves of most cycads are once-divided (pinnate) and often develop an attractive palm-like crown
- Palm trees are a type of evergreen plant belonging to the Arecaceae family of plants
- Palm trees have branch-less stems and large evergreen leaves
- Generally, leaves of palm trees are either pinnate (feather-like leaves) or palmate (fan-like fronds)
- Another way to identify the type of palm tree is by the trunk shape, some of the tallest species of palm trees have long slender single trunks and dwarf varieties have usually short fat palm trunks
- Some smaller palm tree species may have clustered trunks with 3 or 4 short trunks growing together
- There are also some dwarf palm trees that just have bushy pinnate fronds growing out the ground and don’t have any trunk at all
<span>Models are very helpful, but they also have limitations.Details - Models cannot include all the details of the objects that they represent. For example, maps cannot include all the details of the features of the earth such as mountains, valleys, etc.Approximations - Most models include some approximations as a convenient way to describe something that happens in nature. These approximations are not exact, so predictions based on them tend to be a little bit different from what you actually observe. Models do not behave exactly like the things they represent.Accuracy - In order to make models simplistic enough to communicate ideas, some accuracy is lost. For example, ball and stick models of atoms do not show all the details that scientists know about the structure of the atom.</span>
