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.
I NEED FACTS ABOUT LIQUIDS AND GAS FOR ATOMIC THEORY
Answer: Liquid: A liquid is a form of matter. It is settled between solid and gas. Liquid has an almost-fixed volume, but no set shape. Every small force makes a liquid change its shape by flowing. Because of that, gravity makes liquids always take the shape of the container. The molecules that make up the liquid can freely move among themselves.A gas consists of a large number of extremely small molecules which are exactly identical in all respects.
Gas: The molecules are rigid and perfectly elastic spheres of very small diameters.
The intermolecular forces between gas molecules are negligible.
The molecules are in a state of random motion i.e. they move with all possible

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
Methane and oxygen react to form carbon dioxide and water. the reaction speed can be increased by: A.

D.
increasing the concentration of oxygen.
Answer:
c, got it right on study island
Explanation:
The speed of reaction can be increased by increasing the concentration of reactants such as oxygen or methane.
What do you mean by a Chemical reaction?A chemical reaction may be defined as a process that leads to the transformation of one chemical substance into another.
It is thought that the rate of reaction depends on the initial concentration of the reactants. Hence, increasing the reactant's initial concentration will definitely increase the speed of reaction.
Therefore, the correct option for this question is D.

what forms the genetic code?
Answer:
Genetic code is the term we use for the way that the four bases of DNA--the A, C, G, and Ts--are strung together in a way that the cellular machinery, the ribosome, can read them and turn them into a protein. In the genetic code, each three nucleotides in a row count as a triplet and code for a single amino acid.

Why are humans dependent on healthy ecosystems throughout the world?
Answer: Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Significant direct human health impacts can occur if ecosystem services are no longer adequate to meet social needs.
Explanation:
Humans are dependent on healthy ecosystems as they provide resources, regulate climate, purify water, control diseases, offer recreational and cultural values, and drive economic activities.
For a number of reasons, functioning ecosystems are essential to human existence. supplying resources Healthy ecosystems offer vital resources like food, fresh water, clean air, and building supplies like fibre and wood. These materials provide for our basic necessities and are essential to our survival. Genetic and biological diversity: Numerous plant and animal species are supported by ecosystems, which increase biodiversity. Ecosystem stability is ensured by biodiversity, which also increases resilience to environmental changes and offers genetic diversity.

A heater provides heat to an area, but the temperature in the area stays about the same. What do you already know about this phenomena?
ANSWER: IT'S CALLED THE ZEROTH LAW OF THERMODYNAMICS
EXPLANATION:
The zeroth law of thermodynamics state that there's no heat transferred between two objects in thermal equilibrium (i.e having the same temperature). This phenomenon depicts that there's balance in the amount of temperature in all the three entities.
This phenomenon was credited to Sir Ralph Howard Fowler, a British physicist and astronomer during his lifetime.
A scientific paper by Carathéodory also added that when two systems S1 and S2 are made to reach equilibrium with a third system S3 under close thermal conditions, systems S1 and S2 are said to be in mutual equilibrium.

What do cells in the spongy mesophyll layer have that makes gas exchange easier?
Answer:
The spongy mesophyll cells are adapted for gas exchange. They are loosely-packed with large intercellular air spaces where gases can readily diffuse. They have fewer chloroplasts than palisade cells, so carry out less photosynthesis . When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them.
