Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases
The following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
What is the significance of the endothermic reaction?There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.
Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

what makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

Explanation:
Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radish seeds at varying depths. He used the same type of soil, kept the plants in the same location, and gave them each 20 milliliters (mL) of water each day. Then, he measured the height of the sprouts every day for two weeks. What are the independent (test) and dependent (outcome) variables in Chap's experiment?
Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.
The earth rotates on its axis in a counterclockwise direction once every 24 hours, deflecting anything traveling long distances on or above the surface. This is known a the Coriolis Effect. What impact could the Coriolis Effect have on weather patterns
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.

During cell reproduction, chromatin fibers coil up into structures called
a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes
During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.
What are chromosomes?Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.
Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.
During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.
The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

5. Consider two soil samples, one from a tropical rain forest and the other from a temperate
deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer
Answer:
Temperate deciduous forest
Explanation:
The temperate deciduous forest will have more organic matter concentration in it.
Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.
Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.Describe the factors that influence the development and type of soil in a certain area.
Soil research has shown that soil profiles are influenced by five separate, yet interacting, factors: parent material, climate, topography, organisms, and time. Soil scientists call these the factors of soil formation
Answer:
Factors that determine a soil's characteristics include: the type of parent rock from which the soil forms, the climate in the area, the slope of the land, the type and amount of vegetation, and the length of time the rock has been weathering.

Had the same problem
The effect of temperature on these molecules are ;
ATP will increase NADPH will also increase while Sugars will decreaseATP ( Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.
NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.
Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

A non-polar fatty acids prevent cell membrane from dissolving in water. The correct option is A.
What is a cell membrane made of?The cell membrane, also known as the plasma membrane, is uncovered in all cells and serves to separate the cell's interior from the outside environment.
The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.
As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.
