True or false earth is a single interconnected system :)
Answer:
True.
Explanation:
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. These components are also systems in their own right and they are tightly interconnected.
Describe the term "semi-permeable" (or "selectively-permeable) membrane. Why is it important? (giving brainliest to the first person lol)
Answer:
Cells need a selectively permeable barrier sometimes called a semi-permeable membrane because some items need to be allowed to come in while others need to be let out of the cell.
Explanation:
Semi-permeable membranes allow the cell to keep a isotonic state. The amount of water is the same inside as outside the cell.

Explanation: They are all Renewable resources
Which of the following processes must occur for a forest ecosystem to recover after a wildlife? a)development b) evolution c)succession d) mutualism
Answer:
c) succession
Explanation:
Succession, in Ecology, refers to the series of changes that occurs to the structure of a biological community. Succession is of two types namely: primary and secondary succession. Primary succession is the colonization of an area for the first time by organisms called PIONEER SPECIES.
Secondary succession involves the recolonization of an area that has already been affected by environmental disturbances like hurricane, earthquake, wildfire etc. The already present SOIL makes it possible for certain organisms to colonize the affected area.
Therefore, succession (specifically secondary succession) is what must occur for a forest ecosystem to recover after a wildlife.

Answer:
Mitochondria:An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. Also known as the 'powerhouse of the cell.'
Cell wall:A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Nucleus:The positively charged central core of an atom, consisting of protons and neutrons and containing nearly all of the cell's mass.
Golgi bodies:The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.
ER (Endoplasmic Reticulum):A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough.
Cell Membrane:The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Ribosomes:A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.
Cytoplasm:The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.

What kind of rays are produced when a metal, such as tungsten, is bombarded with
electrons moving with very high velocities?
a. x-rays
b. gamma rays
c. cathode rays
d. infrared rays
Answer: x-rays
Explanation: When the electrons from the filament strike the tungsten target, x-rays are created photons are created if they either hit a target nucleus directly (rare) or their path takes them close to the nucleus. If a high- speed electron hits the nucleus of a target atom, all its kinetic energy is transformed into a single x-ray photon.

Explanation:
Most fields that are irrigated year after year will eventually build up salt in the soil as water regularly evaporates and leaves some salt behind. One way farmers minimize this salt build up is to flood their fields every few years before planting. This flood water leaches out the salt in the soil. What advantages and disadvantages do you see in this approach?
Answer:
An advantage is that the salt will be washed out and a disadvantage is that it still leaves some salt behind
Explanation:
Irrigation is an agriculture practice which includes watering the cropland, this practice is advantageous as it washes the salt out of the soil however, some amount of salt still remains which affect the concentration of salts in soil.
What is irrigation?
Irrigation is the agricultural process which includes applying the controlled amounts of water to the land to assist the production of crops, as well as to grow the landscape plants and lawns in the agriculture lands. It may be known as watering in lawns. Agriculture which does not need irrigation but relies only up on the direct rainfall is referred to as rain-fed agriculture.
An advantage of the approach used in this case is that the salt will be washed out of the soil and a disadvantage of this approach is that it still leaves some salt behind in the soil which decreases the diffusion of water through roots due to increase in concentration of soil.

2. When diffusion has reached equilibrium, we say that
the net movement of the molecules is zero. Does this
mean these molecules below would stop moving?
Answer:
See Below.
Explanation:
The key word here is net. The net movement has reached zero when a system is in equilibrium but there are still motion's going back and forth due to statistics and just random brownian motion.
Think of it this way, if there are 100 people walking forwards in a crowd but 2 are moving against the crowd, the net movement is still forwards because the bulk of people are going in that direction. However, there are still 2 people moving against.
Same here, if we are talking about a diffusion, let's say in the case of osmosis, if most of the solute is moving across a membrane then we'd say its net direction is that way but that doesn't mean that there aren't processes happening in the other direction. Water molecules in osmosis mostly diffuse, chemically speaking (because you can say this biologically in a different way), from the probability of water molecules colliding with each other and passing the membrane so even if there is a net movement in a certain way their random motion can make them go to the other side just as well. If the fact that motion stops at equilibrium were the case a lot of systems, both chemical and biological, would not exist as we know it.
Think net = bulk NOT total or entire.
When the net movement is Zero at equilibrium ; An insignificant number of molecules are still moving below
When diffusion reaches equilibrium most of the molecules moving from the areas of higher concentration to areas of lower concentration will stop moving, but a negligible number of molecules will continue to move due to random Brownian motion.
When we say the net movement of molecules at equilibrium is zero it is because majority of the molecules have stopped moving and not all the molecules therefore there will be an insignificant movements of molecules still occuring.
Hence we can conclude that When the net movement is Zero at equilibrium ; An insignificant number of molecules are still moving below
