Answer:
Communicate with one another by means of solvent variables.
Explanation:
Numerous microbes are known to coordinate their pleasant activities and physiological techniques through a framework called majority detecting in which bacterial cells talk with each other by releasing, detecting and responding to minimal diffuse-able banner particles. The limit of microscopic organisms to give and carry on as a get-together for social correspondences like a multi-cell animal has given basic favorable circumstances to microbes in have colonization, plan of bio-films, guard against contenders, and acclimation to developing circumstances. Basically, various QS-controlled activities have been related with the hurtfulness and pathogenic capacity of microscopic organisms

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
Answer: Many pathogenic fungi are parasitic in humans and are known to cause diseases of humans and other animals. In humans, parasitic fungi most commonly enter the body through a wound in the epidermis (skin). Such wounds may be insect punctures or accidentally inflicted scratches, cuts, or bruises. One example of a fungus that causes disease in humans is Claviceps purpurea, the cause of ergotism (also known as St. Anthony’s fire), a disease that was prevalent in northern Europe in the Middle Ages, particularly in regions of high rye-bread consumption. The wind carries the fungal spores of ergot to the flowers of the rye, where the spores germinate, infect and destroy the ovaries of the plant, and replace them with masses of microscopic threads cemented together into a hard fungal structure shaped like a rye kernel but considerably larger and darker. This structure, called an ergot, contains a number of poisonous organic compounds called alkaloids. A mature head of rye may carry several ergots in addition to noninfected kernels. When the grain is harvested, much of the ergot falls to the ground, but some remains on the plants and is mixed with the grain. Although modern grain-cleaning and milling methods have practically eliminated the disease, the contaminated flour may end up in bread and other food products if the ergot is not removed before milling. In addition, the ergot that falls to the ground may be consumed by cattle turned out to graze in rye fields after harvest. Cattle that consume enough ergot may suffer abortion of fetuses or death. In the spring, when the rye is in bloom, the ergot remaining on the ground produces tiny, black, mushroom-shaped bodies that expel large numbers of spores, thus starting a new series of infections.
Answer:
Plant is a common example of a Producer.
Producers are also known as autotrophs.They are organisms which make their own food. They do so by getting energy from chemicals or the sun and with the help of water convert the energy into useable forms such as sugar.
The order of Producers that colonize the land After Lichens include
Annual herbaceous plants
Perennial herbaceous plants and grasses
Shrubs
Shade intolerant trees
Shade tolerant trees.
Answer:
If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.
Explanation:
When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.
A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.
Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
- <em>Adenine 30%.
</em>
- <em>Thymine 30%.
</em>
- <em>Cytosine 20%.
</em>
- <em>Guanine 20%.
</em>
- <em>Total ..... 100%
</em>
In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
