Succession by facilitation is an evolutionary process in which different types of adaptive modifications emerge and they are triggered by the occurrence of genetic features (allele emergence) and environmental conditions.
What is succession by facilitation?In terms of evolution, succession by facilitation refers to the ecological phenomenon in which a disturbed environment can be exploited by a particular pioneer species, which largely depends on their own intrinsic features (genetic background) and the environmental conditions that leads to their emergence in the disturbed area.
This process (succession by facilitation) is triggered by the phenotypes in some individuals which are selected by the environment in order to ensure the evolutionary success of other organisms.
In conclusion, succession by facilitation is an evolutionary process in which different types of adaptive modifications emerge and they are triggered by the occurrence of genetic features (allele emergence) and environmental conditions.

The cell in the photograph is a Eukayotic cell since the structure with the label "x" is the nucleus. The cell in the image is a plant cell since the component marked with the letter "w" is the chloroplast.
What is plant cell?
Plant cells are the essential building element of life in species of the order Plantae. These cells, which are referred to as eukaryotic cells, contain a true nucleus as well as specialized parts called organelles that have various functions. Only in plants are chloroplasts, specialized organelles that utilise photosynthesis to make sugars in their cells.
Eukaryotic cells found in plants differ significantly from those seen in other eukaryotic organisms in a number of significant ways. One of the traits that sets a plant cell apart from other cells is the presence of a cell wall outside of the cell membrane.

To result in an action potential in the central nervous system, EPSP's must ____ through temporal and spatial summation to ____ threshold voltage.
O add up; exceed
O accelerate; reach
O flow; polarize
O sum; activate
Answer:
accelerate; reach
Explanation:
EPSPs fire to trigger action potentials in the postsynaptic cell, by getting the membrane potential to threshold at the axon hillock true, or initial segment of the axon
synaptic knob can fire several times, as others fire as well, so EPSPs can be summed or added; the whole cell body depolarizes, causing current flow, eventually causing an AP to propagate down the axon if brought to threshold at the axon hillock/initial segment.
-remember, as one synaptic knob firing causes 0.5mV charge, you need much more than one to get to threshold.
T/F: if a knob is closer to the axon hillock, more charge will get to it
EPSPs, as described above, are what happens in efferent neurons, which go to effectors, and in interneurons, which are found in the CNS between afferent and efferent neurons
-we already covered afferent neurons, which cause APs to fire in the membrane next to the receptor (toward the CNS)
Water is the most abundant molecule in the body, but it is not a biomolecule. Neither are carbon dioxide,
ethanol, or methane. Review the definition of a biomolecule and the structure of these biomolecules
compared to glucose and alanine, and explain why glucose and alanine are important and common
molecules are not biomolecules.
A biomolecule is one that is created by a living thing by definition. Water is therefore the external supply of carbon dioxide that living things use to manufacture proteins to fulfill their energy needs.
Water molecules have a slightly positive and a slightly negative side as a result of the unequal sharing of electrons.
There is neither a positive nor a negative side to some molecules, as ethane.The unequal distribution of electrons within the polar molecule is what distinguishes polar (water) from non-polar (ethane) molecules. Covalent bonds in nonpolar molecules have an equal number of electrons.Within aqueous solutions, water is universalizing everything formed from atoms and molecules.Molecules of two or more substances are combined in a homogenous manner to form solutions. Typically, the chemical with the highest concentration is the solvent. Some chemicals are soluble in little doses.Learn more about biomolecules here:

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well
as some diseases, such as Alzheimer's, that are caused by proteins that have misfolded. The folding of these
complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even
expensive supercomputers to do this.
A group of researchers at Stanford University developed software that can be used to distribute the processing of data to
anyone who is willing to donate time on their idle personal computers. As a result, the researchers have been able to
achieve protein-folding simulations that are far better than those other computing methods have done. Which statement
best describes the work of these researchers?
Running an experiment required the researchers to use ingenuity to tackle an issue.
The correct answer is "Running an experiment required the researchers to use ingenuity to tackle an issue."
It is the best choice since researchers can process data on anyone's computer who wishes to lend it to them, thanks to software that scientists created. In other words, they came up with a clever solution to the time and financial constraints that the simulation of these proteins folding had.Since the data can be replicated using the program, the work qualifies as scientific, and the fact that the data were not processed in a single location does not change this.The researchers employed more than just tried-and-true scientific methods. It is not a proven scientific method for anyone to be able to contribute time from their computer using software.In conclusion, the answer given above is the best one. Scientists employed ingenuity to find a solution; otherwise, it would have cost time and money to slow down or cease the research.To learn more about protein molecules visit:

What is the Lymphatic system?
The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system, and complementary to the circulatory system. It consists of a large network of lymphatic vessels, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues. The vessels carry a clear fluid called lymph (the Latin word lympha refers to the deity of fresh water, "Lympha") back towards the heart, for re-circulation.
Unlike the circulatory system that is a closed system, the lymphatic system is open. The human circulatory system processes an average of 20 litres of blood per day through capillary filtration, which removes plasma from the blood. Roughly 17 litres of the filtered blood is reabsorbed directly into the blood vessels, while the remaining three litres are left in the interstitial fluid. One of the main functions of the lymphatic system is to provide an accessory return route to the blood for the surplus three litres.
The other main function is that of immune defense. Lymph is very similar to blood plasma, in that it contains waste products and cellular debris, together with bacteria and proteins. The cells of the lymph are mostly lymphocytes. Associated lymphoid organs are composed of lymphoid tissue, and are the sites either of lymphocyte production or of lymphocyte activation. These include the lymph nodes (where the highest lymphocyte concentration is found), the spleen, the thymus, and the tonsils. Lymphocytes are initially generated in the bone marrow. The lymphoid organs also contain other types of cells such as stromal cells for support. Lymphoid tissue is also associated with mucosas such as mucosa-associated lymphoid tissue (MALT).

Basically you need to get several goldfish and different containers that are a different water temperature.
Explanation:
Get your goldfish. About 3-4 because the water should affect each of them about the same, so you want to make sure that it is the same outcome each time and not just a fluke.Get your water containers. Ideal water for goldfish is about 68-74 degrees. Anything below 68 is considered to cold, and anything about 74 degrees would be considered to hot. However, with this experiment, you will need "cold" water (anything under 67 degrees ideally anything under 55 degrees would be nice and "cold" for the fish), ideal water (68-74 degrees), and then "hot" water (anything above 75 degrees. Ideally about 77 - 85 degrees would be hot enough for them)Next I'd say form your hypothesis. When water is too cold, goldfish may stop eating, begin hibernating or die. When the water is to hot goldfish will become very stressed, and can overheat and die. So, choose a hypothesis from that.Your independent variable would be the water temperature, because it doesn't depend on anything. While how your goldfish act would be the dependent variable because they act according to the water temperature.Good luck with your experiment, and this is all I got for ya! Good luck!

Estuaries are partially enclosed water bodies.
Water bodies called estuaries and the marshes that surround them are typically found where rivers and the sea converge.
Unique plant and animal communities that have adapted to brackish water, which is a mixture of fresh water that drains from the land and salty ocean, can be found in estuaries.
Many of the environmental services and features that brackish estuaries provide, such as acting as natural runoff filters and functioning as nursery grounds, are also provided by these freshwater estuaries.
They have clean water and provide a safe growing and protected environment and hence are great spawning grounds for a wide variety of fish and shellfish.
