What happens when you add additional lightbulbs (a type of resistor) to a series
circuit? Check all of the things that happen.
-The light bulbs will get more dim with each bulb that is added.
-The resistance in the
circuit increases with each item that is added.
- The lightbulbs will get brighter with each bulb that is added.
-The circuit will not light
Answer:
the light bulbs will get more dim with each bulb that is added
Explanation:
i dont know how to explain it, but im sure it's right.... i hope ....
When you add additional lightbulbs (a type of resistor) to a series circuit then the light bulbs will get more dim with each bulb that is added. Hence option A is correct.
What is circuit?Circuit is defined as a device constructed from various smaller electrical components that can direct electricity via itself to power bigger devices. Electricity can flow continuously in a closed circuit from the power source, to the conductor or wire, to the load, and then back to the ground or power source.
A series circuit will have increased resistance if additional light bulbs or resistors are added. As a result, the circuit's current and lamp brightness will be diminished. The brightness of each light bulb gradually lowers as more are added. This observation suggests that the circuit's current is diminishing. Therefore, for series circuits, the overall current within the circuit falls when more resistors are added.
Thus, when you add additional lightbulbs (a type of resistor) to a series circuit then the light bulbs will get more dim with each bulb that is added. Hence option A is correct.

Sara is watching television when the power goes out. When she walks to the kitchen to get a candle, she knocks over a chair. She lights a match and holds it to the wick of the candle. She uses the light from the candle to find her way to the chair, which she picks up and sits in. Which of the events was a chemical change? *
Answer:
She lights a match and holds it to the wick of the candle.
Explanation:
Chemical change produces the required products of reactants by an irreversible reaction. For there to be a chemical change, a chemical reaction between reactants must occur.
Lighting of a match is a chemical change in which the friction between the match box and the gun powder on the stick produces a flame. This reaction produces a product by an irreversible process. After the flame burns out the wick of the candle, it can not be reversed.
The region inside the cell except for the nucleus
Answer:
cytoplasm
Explanation:
the cytoplasm is all of the material within a cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm.
The region inside the cell except for the nucleus is cytoplasm. Except for the cell nucleus, the whole contents of a cell that are protected by the cell membrane are known as the cytoplasm.
What is cytoplasm?The cytoplasm is a region in eukaryotic cells that is situated between the nuclear membrane and the plasma membrane.
Typically, the cytoplasm is split into two halves. Ectoplasm, the outermost area, is more viscous and is referred to as such. The endoplasm, which is found in the innermost part, is more fluid.
Except for the cell nucleus, the whole contents of a cell that are protected by the cell membrane are known as the cytoplasm. Nucleoplasm is the name for the substance that makes up the nucleus and is enclosed within the nuclear membrane.
Therefore, the area except for the nucleus in the cell is the cytoplasm, which is filled inside the cell.

explain how ground water is recharged?
Explanation: Natural groundwater recharge occurs as precipitation falls on the land surface, infiltrates into soils, and moves through pore spaces down to the water table. Natural recharge also can occur as surface-water leakage from rivers, streams, lakes, and wetlands.
Answer:
Groundwater is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge may be impeded somewhat by human activities including paving, development, or logging.

People in a rural community share a forest. By agreement, each family can cut 10 trees per year for
personal use. One year, one person cuts 20 trees to build a shop that's nicer than the neighbor's shop. The
new shop flourishes, and despite the general disapproval, nothing is done to punish the cheater. The
neighbor, seeing this, decides that it's okay to go ahead and take 25 trees. Other neighbors follow suit. After
a few years, the forest plot is gone, and everybody must travel much farther for wood. What's this an
example of?
O A Natural Law of the Land
OB. Tragedy of the Commons
OC. Voluntary approach to environmental policy
O D. Conservation Property RightS
Answer: B : Tragedy of the commons
Explanation:
Since the forest plot has been depleted (gone) and everybody must travel much farther for wood, this is an example of: B. Tragedy of the Commons.
What is Tragedy of the Commons?Tragedy of the Commons can be defined as an economic situation in which individuals with access to a shared (common pool) resource act in their own selfish interest while retroactively depleting this resource.
This ultimately implies that, it is an economic problem of overconsumption by individuals sharing a common resource and it eventually leads to the depletion of the resource.

Heterozygous is another word for what?
Answer:
Heterojunction or having two identical alleles of the same gene.
Explanation:
A heterojunction is an interface that occurs between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are commonly used interchangeably. The requirement that each material be a semiconductor with unequal band gaps is somewhat loose, especially on small length scales, where electronic properties depend on spatial properties. A more modern definition of heterojunction is the interface between any two solid-state materials, including crystalline and amorphous structures of metallic, insulating, fast ion conductor and semiconducting materials.

Variation in intergroup relationships among species and among and within local populations of African apes-evolutionary process
despite the truth that many animals shield important sources from conspecifics at some stage in interactions, several primate species automatically have interaction in tolerant encounters. In terms of evolutionary process intergroup relationships, as an instance, African apes and people (Homininae) show off full-size range, and local human groups are hooked up thru a community of affiliative relationships amongst corporations. We have to have a look at variance between species, between populations, and inside populations to be able to comprehend this range and its evolution. even as bonobos' intergroup connections are typically affiliative, each jap and western chimpanzees often exhibit adverse intergroup ties. despite the fact that the percentages of corporations with numerous adult males within the genus Gorilla range, all subspecies show off great domestic range overlap and each adversarial and affiliative intergroup interactions. in regards to neighborhood populations of the same (sub)species, there are few variations between Pan and Gorilla. The distribution of girls within corporations seems to play a position in the affiliative relationships among bonobos, however intergroup connections differ in the identical neighborhood populations in different species. those patterns in bonobos seem like just like the ones in local human communities, wherein lady dispersal amongst corporations performs a huge function in affiliative relationships and intergroup connections vary for extraordinary combinations of companies. All gorilla subspecies showcase a variety of intergroup connections, from affiliative to competitive, and relatives relationships between leading males are vital to the development of affiliative relationships. studies on intergroup variation, the roles played through ladies and men in that variation, and the genetic make-up of the neighborhood populations may additionally assist us higher apprehend the evolutionary process that gave upward thrust to neighborhood groups within the Homininae.To learn more about the evolutionary process here:-
