Well as the population grows, our resources start to decrease. More resources are wasted every single day of our lives and we still keep digging them all out, what makes it worse is, since animals keep going endangered, humans keep coming and coming and if it keeps happening we will have no animals. Not to mention people are burning forests, the things we need to breathe.

4 substances containing nitrogen or phosphorous that are related to biological processes

Answers

Answer:

DNA, RNA, ATP, and the phospholipids that form all cell membranes

Explanation:

Metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. Again, thinking about the formation process can help. Metamorphic rocks have been heated and squashed. This can lead the minerals in them to line up, creating ribbon-like layers called bands. These rocks are called foliated metamorphic rocks. You can see these bands in gneiss. If a metamorphic rock has fossils, you know it was formed from a sedimentary rock. Because of the heat and pressure, the fossil will be hard to recognize and out of shape.

Which of the following best describes foliated metamorphic rocks?

A
There are easily recognizable fossils.

B
The rock has ribbon-like layers of bands.

C
They have crystals like igneous rocks.

D
Different sized sediments can be see

Answers

Answer:

b

Explanation:

the fourth sentence in the passage: "This can lead the minerals in them to line up, creating ribbon-like layers called bands."

Dark and light bands may alternate due to the separation of mafic (dark) and felsic (light) minerals.  Having different grain sizes in the same mineral can also result in banding. Thus, option B is correct.

What are the ribbon layer present in the rock?

Under the surface of the earth, metamorphic rocks are formed. The extreme heat and pressure cause them to alter. Their layers resemble ribbons. Some of them are covered in bright crystals.

Under the earth's surface, metamorphic rocks are created as a result of the transformation brought on by extreme heat and pressure (squeezing).

These processes produce rocks that frequently have layers that resemble ribbons and may have glittering crystals on their surface that were created by minerals slowly growing over time.

Therefore, This can lead the minerals in them to line up, creating ribbon-like layers called bands

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).

Answers

Answer:

Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

Density independent factors affect populations regardless of their size. Examples are winter, drought, forest fires. These factors are mostly abiotic (non-living). Predation affects population size.

disease

The factors that will affect a population regardless of population density is flooding. The correct option is C.

What is population?

A population is the entire group about which you want to draw conclusions. A sample is the specific group from which you will collect data.

The sample size is always less than the total population size. A population for this research does not necessarily refer to people.

A population is a subset of individuals from one species that live in a specific geographic area and interbreed in reproducing species. Some species' geographic boundaries are easy to establish, while others are more difficult.

Population change is influenced by three factors: birth rate, death rate, and migration. Though one or two of these factors may have an impact on a population in a specific area, all three have an impact on population change.

Thus, the correct option is C as the population can be get affected by flooding without regarding their density.

Heat flows from the coffee to the spoon through radiation.
Heat flows from the coffee to the spoon through convection.
Heat flows from the coffee to the spoon through conduction.
Heat flows from the coffee to the spoon through radiation, convection, and conduction.

Answers

Answer:

C. Heat flows from the coffee to the spoon through conduction.

The heat movement known to move from one area to elsewhere has been called heat transfer. Thermal conduction allows the coffee's heat to reach the spoon. Thus, option C is correct.

What is thermal conduction?

A type of heat transfer called thermal conduction occurs when heat flows from one spot to some other place due to the disparity in temperatures between the bodies.

When a body is subjected to thermal conduction, heat energy is dissipated from the body towards the colder or less heated objects. Because the spoon and coffee are at different temperatures, the heat from the coffee is passed to the spoon through conduction.

Therefore, thermal conduction is the process through which the coffee heats the spoon in the cup.

d. the environment in which cellular respiration occurs.

Answers

A. I believe, because a chemical reaction equation is a shorter way to represent a chemical reaction.

The chemical equation of cellular respiration comprises information regarding the relative amounts of products and reactants.  

• The process, which takes place within the mitochondria of all the organisms is termed cellular respiration. In this process, the simple sugars are dissociated into water and carbon dioxide and release energy in the form of ATP.  

• A chemical reaction is a procedure in which one or more components, that is, the reactants get transformed into one or more different components called the products.  

• The substances, which start the reaction are called reactants, while the ones that get produced in the reaction are called products.  

• The association between the reactants and products in a chemical reaction can be signified with the help of a chemical equation.  

Thus, the chemical reaction of cellular respiration comprises information regarding the relative amount of products and reactants.
