Answer:
d.??????????????????
Answer: C!
Explanation: eukaryotic cells may divide via either mitosis or meiosis. only sexually reproducing eukaryotes can engage in meiosis. all eukaryotes — regardless of size or number of cells — can engage in mitosis.
Having no cell nucleus, archaea do not reproduce via mitosis; rather, they procreate using a process called binary fission. So D AND E are eliminated. And so is B because that has bacteria.
SO FINAL ANSWER; mitosis happens in eukaryotes, plant and animal cells
Some of the organic material manufactured in the estuarine communities is exported to other ecosystems. What type of ecosystems receive this material
Answer:
Coastal and open-water ecosystems
Explanation:
Organic material manufactured in estuarine communities is exported to coastal and open water ecosystems. This organic material is very beneficial to these ecosystems as it allows many nutrients to float in the changing tides. These nutrients are a very rich food source for coral reefs and kelp forests. Furthermore, these nutrients arrive in the ecosystem in the form of debris that can serve as breeding grounds for very important organisms in the region and that serve to maintain the food chain.

Which of the following statements about the energy needs of cells is false?
1. The most usable energy for cells comes from the rapid combustion of glucose
2. Many cellular reactions have an associated activation energy
3. The laws of thermodynamics force cells to acquire energy
4. Without a continuous input of energy, cell disorder will increase
Answer:
A the most usable energy for cells comes from the rapid combustion of glucose
The statement 'the most usable energy for cells comes from the rapid combustion of glucose' is FALSE (Option 1).
Glucose is a simple carbohydrate that provides a rapid energy source to the cells.In animals, glucose is used to produce glycogen, which is a complex carbohydrate that provides a long-term source of energy.All metabolic reactions in a cell depend on the presence of activation energy, which generally is provided by ATP, the energy coin of the cell.In conclusion, the statement 'the most usable energy for cells comes from the rapid combustion of glucose' is FALSE (Option 1).

Which of the following best describes the producers in a terrestrial food web?
a- They convert energy from the sun to chemical energy.
b- They are at the top of the energy pyramid.
c- They are unaffected by decomposers.
d- They obtain their energy from consumers.
Answer:
The correct answer is - a- They convert energy from the sun to chemical energy.
Explanation:
Producers in any food web or ecosystem are the organism that can produce the food and energy on their own. Normally these organisms are green plants that can perform photosynthesis in order to produce chemical energy from light energy that comes from the sun.
Producers not only provide food and energy to themselves but also provide food and energy to each trophic level directly or indirectly. Producers are present at the base of the energy pyramid.

Explanation:
Super saturated solutions are used to make rock candy. Please describe how the crystals are formed, be sure to use the terms Solute and Solvent.
Answer:
Once the solution cools, it now has more solute than it normally could have, and this is called a supersaturated solution. Once a solution becomes supersaturated, it wants to crystallize the excess solute. The solute will form crystals on any surface. In our case the surface is a string, and we are using a lifesaver candy as our “seed.”
Explanation:
Rock candy is a type of candy made by growing sugar crystals on a string or stick.
Why are Super saturated solutions used?Super saturated solutions are often used to make rock candy because they contain more solute (sugar) than the solvent (water) can normally dissolve at a given temperature.
The first step in making rock candy is to heat water in a saucepan and add sugar to it. The sugar dissolves and forms a solution as the water heats up. After that, the solution is heated until it is completely saturated.
This occurs because the super saturated solution is unstable, and the excess solute (sugar) in the solution wants to escape and form crystals.
As time passes, more sugar dissolves from the solution and adheres to the crystals on the string or stick, causing them to grow larger.
The process is repeated until the crystals reach the desired size or until all of the excess solute has been removed from the solution.
Thus, preparing a super saturated solution of sugar and water, then dipping a string or stick into the solution and allowing the excess solute to come out of the solution and form crystals on the string or stick, is the process of making rock candy.

A roller coaster at the top of a hill JUST BEFORE it goes over the edge is an
example of
Energy ?
1.)Potential
2.)Kinetic
Answer: A roller coaster at the top of a hill JUST BEFORE it goes over the edge is an example of potential energy.
Explanation:
An energy that is acquired by an object due to its motion is called kinetic energy.
An energy that is acquired by an object due to its position is called potential energy.
For example, when a roller coaster at the top of a hill JUST BEFORE it goes over the edge has only potential energy because it is not in motion.
The energy present in the roller coaster is due to its position that is being at the top of a hill.
Thus, we can conclude that a roller coaster at the top of a hill JUST BEFORE it goes over the edge is an example of potential energy.

What are the events in the volcanic eruption?Volcanic eruption is the movement of magma from the mantle of the crust through the vents in the crust.
The events in the volcanic eruption can be arranged as:
The pressure in the magma allows the gases to expand rapidly inside the crust.The expanded magma gets collected in the magma chamber and allows the pressure necessary for the explosion.The eruption of magma from the vent that is holes in the crust is carried. The holes in the vent allow the release of gases such as carbon dioxide, sulfur from the fumaroles.Thus, the correct sequence of events in the volcanic eruption is B < C < D < A.

Tại sao tóc có mầu đen
Answer:
Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.
