prokaroytic and eukarayotic cells
Answer:
A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus. The word prokaryote comes from the Greek πρό and κάρυον. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota.Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota.

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.

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.

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.

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.

Which component of the digestive tract includes the enzymes that begin digestion of carbohydrates.
A( bile
B( Chyme
C( saliva
D( urea
Answer:
[tex]\boxed {\tt Saliva}[/tex]
Explanation:
The digestive tract and process of digestion actually begin with the mouth. Teeth help break the food up into smaller pieces that are simpler to absorb and digest. Saliva helps moisten the food so it is easier to swallow, but it also contains an enzyme called amylase. This enzyme helps break down carbohydrates into simple sugars and begins the digestion of carbohydrates.
Therefore, the best answer choice is C. saliva.
Which of the following presents the best argument as to the role of the cow in this cycle?
Answer:
Cow dung helps in balancing the environment and kills germs
Explanation:
Cow dung is used for fertility of the soil. It is also used for the control of pest in the plants. When heated cow dung can be used to cook food where there are lack of wood available. Also when it is heated it releases the gases which kills germs present in the air.
Answer:
The cow eats plants and produces carbon dioxide through cellular respiration. The plants, which gain energy from the sun, then take carbon dioxide from the atmosphere and use it in photosynthesis.
