please help

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.

Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. ... When sunlight returns in the spring, the chlorine begins to destroy ozone.

Answer:

Energy

Explanation:

The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.

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.

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.

Answer:

X-rays

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.

Your “genes”, or genetics, are what make you who you are. Chromosomes determine what gender a person is and what they’re like (birth defects).

Answer:

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.'

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.

The positively charged central core of an atom, consisting of protons and neutrons and containing nearly all of the cell's mass.

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.

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.

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.

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.

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.

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

Answer:

There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:

Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Explanation:

Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).

All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

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.

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.
