The system that is not an example of an open system is the pressure cooker.
What is an open system?Let us recall that both the open and the closed systems are the types of thermodynamic systems that we have. In effect, we could say that there are actually about two kinds of thermodynamic systems and these are the open system and the closed system. The open system is the system min which there is an exchange of materials and energy with the external environment while in the closed system, there is no exchange of material and energy with the external environment.
Having said this, whet we now have to look out for is the system where we do not have an exchange of material and energy. That sort of system does not qualify as an open system.
As such, the pressure cooker is a closed and not an open system.

Abdul and Jordan were making crafts. They were using beads, feathers, and crayons to make cards. Jordan got a little too excited at how nice his card turned out and knocked over a glass of water on their supplies. The beads, feathers, and crayons were all soaked in water. Which of the following explains what will happen to the craft supplies?
The crayons will dissolve in the water.
The feathers will dissolve in the water.
The beads will dissolve in the water.
None of the craft supplies will dissolve.
None of the craft supplies will dissolve when water soaks the supplies and is therefore denoted as option D.
What is Dissolve?This is referred to as the process in which a solute is merged with a solvent thereby forming a solution and it varies according to certain properties and features.
The supplies such as beads, feathers, and crayons are all incapable of forming a solution with water as a result of their molecular structures and their non polar parts which is why they are referred to as being insoluble substances.
On the other hand substances like salt, sugar are capable of dissolving in water and forming a solution which are referred to as soluble substances which is therefore the reason why option D was chosen as the most appropriate choice.

Density is mass per unit _____________________ ?
Question 10 options:
strength
volume
weight
length
Answer: Volume
Explanation: The formula of density is Density = mass/volume.
Volume is how much space something takes up.
If Earth suddenly weighed twice as much as it currently does, how would this change the tides? Explain.
The mass might now no longer change. The weight (mg) might be expanded through two times the quantity of the acceleration because of gravity to that of Earth, that is 9.8ms2 on Earth.
Tidal forces are primarily based totally at the gravitational appealing pressure. With regard to tidal forces at the Earth, the space among items commonly is extra important than their masses. Tidal producing forces range inversely because the dice of the space from the tide producing object.the pressure of gravitational appeal among them additionally increases.
If the mass of one of the items is doubled, then the pressure of gravity among them is doubled. If the mass of one of the items is tripled, then the pressure of gravity among them is tripled.

When the Carbon dioxide changes its state from gas to solid directly that is called dry ice.
How might dry ice be used for cleaning?Similar to sand blasting, dry ice cleaning, commonly referred to as cryogenic cleaning, uses solid CO2 or dry ice pellets instead of sand. The pellets expand by a factor of 700 when they hit the ground and evaporate into carbon dioxide gas. This expansion causes the contaminant to be raised and separated from the basic substance. creates daily dry ice blasting tools and exports them to numerous nations across the world.
In order to create dry ice, gaseous CO2 is first compressed and rapidly cooled to create liquid CO2. The liquid is next allowed to expand at a lower pressure to create CO2 snow. Finally, a hydraulic press compresses this snow into usable Dry Ice blocks, slices, or pellets.

How does oxygen reach the cells of the body? Explain how the respiratory and circulatory systems work together to supply cells with the materials they need?
According to the research, the respiratory and circulatory systems have the anatomical structures responsible for pumping and distributing blood throughout the body.
How the respiratory and circulatory systems work together?The circulatory system has the main function of transporting blood throughout the body; this blood will contain nutrients and oxygen so that they reach all the cells where the respiratory system is responsible for capturing oxygen.
In this sense, this process is carried out by means of two circuits that process blood with oxygen and deoxygenated blood:
Systemic circulationPulmonary circulationVeins that contain oxygenated blood, such as the pulmonary veins, carry oxygenated blood from the lungs to the heart.
Therefore, we can conclude that the respiratory and circulatory systems work through two circuits to transfer oxygen and nutrients from the blood to the cells.

statement that describes the process of cellular respiration
Answer:
Statement that describes the Process of Cellular Respiration is Converting chemical energy that is stored in food molecules into a form that is useful to living things.
Explanation:
Living cells release energy through the breakdown of glucose molecules, a process known as cellular respiration. There are three processes that make up cellular respiration.
GlycolysisKrebs CycleElectron Transport ChainGlycolysis, the first phase of cellular respiration, happens in the cytoplasm. In this step, enzymes convert a glucose molecule into two pyruvate molecules, releasing energy that is then transferred to ATP. Following glycolysis, the pyruvate is transformed into two molecules of acetyl CoA in a brief event known as the transition reaction.
The other two phases of cellular respiration take place in the organelle known as a mitochondrion. The inner membrane of the mitochondrion encloses a region known as the matrix, and the outer and inner membranes are separated by an intermembrane space.
The Krebs cycle, the second phase of cellular respiration, occurs in the matrix of a mitochondrion. At this point, the cycle completes two rounds, producing all of the carbon atoms.

. If the producer level of an ecosystem contains 46,894 calories, how much energy wouldbe found at the secondary consumer level of that same ecosystem?a. 4,689 caloriesb. 468,940 caloriesC. 468 caloriesd. 46,894 calories
Energy levels in an ecosystem
To be able to calculate how much energy there is at a certain level in an ecosystem, it is necessary to understand how the energetic pyramid works: it shows the energy retained as new biomass at each trophic level.
from bottom to top:
-Solar energy
-primary producers: 100% of energy
-primary consumers: 10% of energy
-secondary consumers: 1% of energy
-tertiary consumers: 0.1% of energy
Therefore, if there is an ecosystem with 46,894 calories, to know how many calories would be at a secondary consumer level it is necessary to multiply that number by 0.01 (which corresponds to 1% of the total energy). Then:
46,894 x 0.01 = 468.94
Therefore, the correct answer to this question is option c, 468 calories.

Answer:
Cones are the reproductive structures of the conifers: Cones are diploid tissue produced by the dominant sporophyte stage. The haploid gametophyte stage develops and produces gametes inside the cone. Seeds: an important evolutionary advance in the conifers.
A) Seeds form after combining pollen and egg cells during sexual reproduction
B) Male pollen grains and female egg cells in the same reproductive organ
C) Cones containing seeds that are eaten and carried away by animals
D) Flowers designed to attract pollinators to assist in fertillization
specialized reproductive structures give spermatophytes their nameAngisperms and gymnospermsAngiosperms have their seeds enclosed inside their fruits while gymnosperms ( non-flowering plants ) have their seeds exposed on their leave surface.The process of seeds forming after the combination of pollen and egg cells in the process of x reproduction represents a descriptive reproductive structure common in gymnosperms and angiosperms
