What two things must exist for an electric current to be produced?
Answer:
A supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges.
Explanation:
Answer:
An electric potential between two bodies and a conducting path joining the bodies.
Explanation:
For an electric current to be produced, there must be an electric potential between two bodies and a conducting path joining the bodies. Two oppositely charged bodies won't produce a current unless there's a conduction path for the electrons to travel through.

Which choice names part of the lithosphere?
A. outer core
B. crust and outer part of the mantle
C. all of the mantle
D. inner core
The correct answer would be B, because the crust is made of rock, and the outer part of the mantle is connected to the crust, therefore having some rocks there also.
The lithosphere is defined as the outermost rocky layer of the Earth. The lithosphere can be explained by the example of the Rocky Mountain Ranges in North America.
The correct answer is:
Option B. crust and outer part of the mantle
The lithosphere is composed of the brittle and outer rocky portion of the mantle and the crust.
The is bounded by the atmosphere above and the asthenosphere. The rocks of the lithosphere are considered elastic. The outer part of the mantle or lithosphere is very important because the biosphere inhabit and lives upon it.
Therefore, option B is correct.

Question 45 (1 point)
(DOK 2) The role of the pancreas in the human body is to make insulin to prevent
individuals from developing diabetes. Sue goes to visit the doctor and the doctor
reports that her pancreas is indeed producing proteins necessary to create insulin
but the proteins are not being delivered to the correct location in the cell, to trigger
the release of the insulin. Which organelle is responsible{for this lack of homeostasis?
vacuole
golgi bodies
nucleus
Endoplasmic reticulum
The organelle here that is responsible for delivering the protein to correct location is Golgi bodies. The correct option is B.
What are Golgi bodies?The Golgi apparatus is an organelle located in almost all eukaryotic cells. It is also referred to as the Golgi complex, Golgi body, or the Golgi.
It is a mandatory part of the cytoplasmic endomembrane system which aids in packaging of proteins into membrane-bound vesicles as they are transported to their destination.
The packaging and transportation of materials would cease if the Golgi apparatus was not present.
Various substances, such as sugar monomers, would be unable to be converted into usable forms. The cell's secretory activities would also cease to exist.
In the given scenario, as Sue's pancreas is indeed producing proteins necessary to create insulin but the proteins are not being delivered to the correct location in the cell, to trigger the release of the insulin.
This shows that she is not able to transport the insulin due to some problems with the Golgi apparatus.
Thus, the correct option is B.

A population of 20 monarch butterfly is colonize a meadow. The meadows carrying capacity for a monarch butterfly's is 5000 individuals. What statement best describes the growth rate of the population of Monarch butterfly after the Meadow is colonized?
Answer:
D
Explanation:
A.
The population grows exponentially until it approaches 5,000 individuals, and then the population size begins to decrease.
B.
The population grows exponentially until it approaches 5,000 individuals, and then its growth rate decreases.
C.
The population grows at a constant rate until it approaches 5,000 individuals, and then its growth rate increases.
D.
The population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.
The statement that best described the growth rate of the Monarch butterfly after the Meadow was colonized would be that the population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.
The carrying capacity generally represents the maximum number of individuals of a particular species an environment can support based on the resources that the environment has. Ideally, the population only stabilizes with very minimal oscillation around the carrying capacity. It neither decreases nor increases significantly unless a major disruption happens.
The only option that addresses the stability of populations around the carrying capacity of the environment is option D.
The correct answer is D.

How does a calorie on a food label relate to a calorie that is produced in cellular respiration?? Please help
Answer:
There are 1000 calories in 1 Calorie (notice the difference in the capital C) on our food labels the Calories are given. Cellular respiration ; the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, begins with a chemical pathway called glycolysis
Explanation:
Hope this helped, Have an amazing, spooky Halloween!!
The relationship between the calorie on a food label with the calorie produced in a cellular respiration is ;
I Calorie on a food label is equivalent to 1000 calories produced in cellular respirationWhen labeling food to indicate the nutrients contained in the food ( especially canned foods ) the amount of calories contained in the food is indicated and for every Calorie ( 1 calorie ) indicated on the label represents an equivalent of 1000 calories found in cellular respiration.
Hence we can conclude that 1 Calorie indicated on a food label is an equivalent of 1000 calories produced in a cellular respiration.

Based on the video, do you think changes to the environment could still affect living things on Earth today? Explain your answer using information from the video to support your argument.
Answer:
I didn't see the video but global warming might be one.
Explanation:
Due to global warming the polar ice caps are melting, so that means a decrease in the food a polar bear might have.
Answer:
An ice age caused Earth’s oceans to cool, which killed many of the unicellular organisms. When the ice age ended and Earth warmed, the continents broke apart. This event allowed the shallow seas to cover the continents. The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.

Where is carbon stored in the environment?
Answer:
Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.
Explanation:
Answer: On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs, or sinks, through which carbon cycle.

each of my nucleotides includes a phosphate sugar and base am i dna or rna
Nucleotides are defined as the building blocks of DNA and RNA. These are the genetic material found in every living cell. The nucleotides are made up of sugar, a phosphate group, and nitrogenous bases.
The molecules like DNA and RNA have some of the building blocks same. The pentose sugar and nitrogenous bases. The molecule when composed of sugar molecules and nitrogenous bases are termed as a nucleoside.
The addition of the phosphate group to a nucleoside forms the nucleotide.
RNA is composed of nitrogenous bases (adenine, cytosine, uracil, and guanaine), pentose sugar (ribose), and a phosphate group.
DNA is composed of nitrogenous bases (adenine, cytosine, thymine, and guanaine), pentose sugar (deoxyribose), and a phosphate group.
Thus, DNA and RNA are nucleosides consisting of nitrogenous bases (purines and pyrimidines) and sugar groups.
Therefore, the correct answer is the molecule can be DNA or RNA.
