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.

Water is a polar molecule. c. Water is an ionic compound.
How does high specific heat help aquatic organisms?
Answer:
Explanation:
Due to its high heat capacity, water is used by warm blooded animals to more evenly disperse heat in their bodies; it acts in a similar manner to a car's cooling system, transporting heat from warm places to cool places, causing the body to maintain a more even temperature.
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.

Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.
What is Biogeochemical cycle?A biogeochemical cycle is defined as the path by which a chemical substance cycles through the biotic and abiotic compartments of the Earth where the biotic factor is the biosphere and the abiotic factors are the atmosphere, hydrosphere and lithosphere.
Nutrients cycle occur through organic components as well as abiotic components. In biosphere the term bio refers to biotic components while 'geo' refers to abiotic components. Therefore, nutrient cycles in nature are called biogeochemical cycles.
Thus, Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.

Explain what white light is and what it's made of, what do we see it as
PLZ HURRY
Answer:
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.
Explanation:
Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

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.

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.
