Starting on bare rock what is the usual ecological succession of organisms
Complete question:
Starting on bare rock, what is the usual ecological succession of organisms?
a)shrubs--grasses--lichens--trees
b)lichens--shrubs--grasses--trees
c)grasses--shrubs--lichens--trees
d)liches--grasses--shrubs--trees
Answer:
d)liches--grasses--shrubs--trees
Explanation:
The succession is the colonization of an open area and includes all the changes the area suffers since then. It is a sequence of events that involves the establishment of different species through time.
There are two types of succession, primary and secondary, depending on the magnitude of the alteration.
Primary succession refers to an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.
In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or moses with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat. They make it more suitable for the establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil, making it better with time. New species arrive, like small species, bushes and shrubs. Habitat modification keeps on going while new species establish (trees, pines, among other big species). They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
Answer:
D. liches--grasses--shrubs--trees
Explanation:
primary ecological succession will be as: lichens inhabit bare rocks and breakdown the minerals rich material in the rock and die to produce organic material so that new species could be formed as grasses will grow which will become shrub and eventually the tree. Animals eat those grass, shrub or tree products.

What is a similarity between wind and water?
A) They are both types of non-renewable resources.
B) They are both sources of power for objects that people use.
C) They can both be polluted by pesticides and fertilizers.
D) They are both sources of oxygen for plants and animals.
Answer:
Hey i think its A :) have a wonderful day !
Explanation:
because they both transfer soil to new places.
Wind is a type of dry deposition method. If original soil is erodable and wind exists, soil particles move via wind (sometimes it is called dust transport) and finally are deposited at final destination regions/areas.
However, water erosion occurs when rainfall or hail occurs. Along with water some soil particles (mostly finer ones) are carried away. Finally close to river mouths (delta regions) or wherever deposition is occurring (within a river canal) these soil particles are deposited.
A) They are both types of non-renewable resources: This statement is incorrect. While there are some forms of energy that are derived from non-renewable sources such as fossil fuels, wind and water are both examples of renewable resources.
How is wind generated ?Wind is generated by the movement of air caused by differences in temperature and pressure, and water is driven by the water cycle, which is powered by the sun. Both wind and water are replenished naturally, making them sustainable sources of energy.
B) They are both sources of power for objects that people use: This statement is correct. Wind and water have both been used for centuries as sources of power to perform work. Wind has been used to power windmills for grinding grain and pumping water, while water has been used to power water wheels for milling grain, sawing wood, and generating electricity.
Today, wind turbines and hydropower plants are common examples of objects that harness the power of wind and water to generate electricity.
C) They can both be polluted by pesticides and fertilizers: This statement is partially correct. While water can certainly be polluted by pesticides and fertilizers, wind is not typically subject to the same kind of pollution. However, it is important to note that wind can carry pollutants and particulate matter, which can impact air quality and human health.
They are both sources of oxygen for plants and animals: This statement is incorrect. While water is an essential component of photosynthesis, the process by which plants produce oxygen, wind is not a direct source of oxygen.
However, wind can play an important role in the dispersal of plant seeds, which helps to facilitate plant growth and regeneration.

How do these tape worms defend themselves from the immune system of their host
ck-12:Unwanted Company
Answer:
Scientists discovered mechanisms that protect tapeworms from being digested by their host. ... They also needed a mechanism to protect themselves from intestinal substances, specifically from digestive enzymes. One of such enzymes called trypsin breaks down proteins.
Explanation:
For example:Parasites can hide away from the immune system by invading immune-privileged tissue such as the central nervous system or the eye (Bhopale 2003). Also some parasitoids place their eggs inside tissue such as the fat body that is not well patrolled by the host's immune system

Answer: E. Turgor
Explanation: can i help u with more?
Turgor pressure gives the non-woody plants their shape. Thus, the correct option is E.
What is Turgor pressure?Turgor pressure is the force which is present within the cell that pushes the plasma membrane against the cell wall. It is also called as hydrostatic pressure, and also defined as the pressure in a fluid which is measured at a certain point within itself when the fluid is at equilibrium.
Generally, the turgor pressure is caused by the osmotic flow of water and occurs in the plants, fungi, and bacteria which contain cell wall. The phenomenon is also observed in the protists which have cell walls. This system is not seen in the animal cells, due to the absence of a cell wall in the cell which would cause the cell to lyse when placed under too much pressure condition.
Therefore, the correct option is E.

What is herd immunity, and why are vaccines important for achieving herd immunity?
Answer:
Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

Separate your answer(s) with a comma, and enter only the letter(s) of your choice(s
Answer:
b. Antibodies are used for Northern blot analysis.
c. VNTRs are highly conserved in human populations.
Explanation:
The northern blot technique is used in molecular biology laboratories for detecting specific RNA molecules in a sample of RNA derived from a particular cell/tissue. Antibodies can be detected by the enzyme-linked immunosorbent assay (ELISA). In ELISA, antigens are used to detect specific antibodies: the addition of the antigen produces a positive reaction i.e., formation of the antigen-antibody binding complex. Subsequently, a second antibody with a particular marker is added to bind with the complex, thereby producing a change in the color and thus evidencing the presence of the target antibody in the sample. On the other hand, the variable number of tandem repeats (VNTR) are short sequences (around 20 to 100 bp) whose number of repetitions varies at specific loci in the genome of many organisms, including humans. Since VNTR sequences exhibit variation in length between individuals of the same species/population, they are widely used as molecular markers to identify individuals, QTL (quantitative trait loci) mapping, establish phylogenetic relationships among individuals/cultivars/lines, etc.
