Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?
Answer:
Mantle layer
Explanation:
The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.
The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.
Muscles have a bunch of nuclei because they need to use the DNA in the nuclei to make the large number of proteins that they must contain, so that they can relax and contract. What other organelle might muscles need a larger than normal number of?
Centrioles, so that muscle cells can retain a rigid structure during times of heavy stress (for example: lifting a heavy weight).
Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.
Vesicles, so that muscle cells can ensure water availability if there is unusually low availability of water.
Answer:
it's the Mitochondria
Explanation:
The other organelle that might muscle needs a larger than normal number of is mitochondria, so that muscle cells can quickly respond to the need to relax and contract. The correct option is b.
What are mitochondria?Mitochondria is a cell organelle that is present in both plant and animal cells. It is not present in prokaryotic cells, as prokaryotic cells do not contain cell organelles. Besides storing ATP, it also generates energy that is generated from glucose.
Muscle cells have mitochondria to accommodate this energy demand. These organelles, often known as the “power plants” of the cell, transform nutrients into the molecule ATP, which serves as a form of energy storage.
Therefore, the correct option is b. Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.

which mosquito cause malaria?
Answer:
Anopheles mosquitoes
Explanation:
Malaria is a common disease characterized by symptoms that include: headache, fever, nausea etc. Malaria disease is caused by a pathogen called PLASMODIUM, which is a protozoan parasite. However, these plasmodium parasites are carried to induce their damage by vectors called MOSQUITOES.
Not all genus of mosquitoes carry this pathogen but specifically ANOPHELES MOSQUITOES. The female species of an Anopheles mosquito carries plasmodium when they feed (suck blood) of an infected person. They then inject it into the bloodstream of another victim they suck from.

the way that genetic information is coded in DNA is-
Answer:
with bases
Explanation:
Genetic information is coded in DNA by means of four bases: two purines (adenine and guanine) and two pyrimidines (thymine and cystosine). Each adjacent sequence of three bases (a codon) determines the insertion of a specific amino acid. In RNA, uracil replaces thymine.

If you are neither relaxing or contracting a specific muscle, what is happening to the amount of ATP that is available in that muscle cell?
A. It is staying the same or increasing.
B. It is decreasing rapidly.
Answer:
A. It is staying the same or increasing.
Explanation:
The body tissues and cells require energy in the form of ATP to work, grow and move. It is produced from cellular processes like ETC, cellular respiration and other metabolic processes.
The amount of ATP in the cell:
Option A. It stays the same or increases.
The function of ATP can be explained as:
Muscle contraction and relaxation requires a certain amount of energy in the form of ATP. The insufficient amount will not be able to support the relaxation or the contraction of the muscle tissues.In the condition where there is no contraction or relaxation the amount of energy will be the same or increased as it is not used in the process and remains constant.Therefore, it remains the same or increases.

What will happen if external factors affect cell division in a group of cells placed in a culture dish
Answer:
The effect of an external physical factor on cell division is clearly seen in density-dependent inhibition, a phenomenon in which crowded cells stop dividing. ... When cells have formed a complete single layer, they stop dividing (density-dependent inhibition).
Explanation:
A scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. What did the scientist most likely learn from the observation? a The reaction caused an output of energy. b The reaction produced water. c The reaction consumed water. d The reaction required an input of energy.
Answer:
a The reaction caused an output of energy
Explanation:
Adenosine triphosphate, commonly known as ADP, is an high-energy storage molecule in living cells. It stores and transfers needed energy for metabolic activities. ATP stores its energy in the bonds that hold the phosphate group in its structure. However, the energy is released for use during metabolic processes when the phosphate bond is broken, leading to the release of ADP molecule.
In this case, a scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. This means that the reaction has caused ATP molecules to release its stored energy i.e. an energy output.
