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.

Which best describes a neutralization reaction? areaction between an acid and a base Oareaction between two acids O a reaction between a base and a salt Oa reaction between two salts
The statement best describes a neutralization reaction is a reaction between an acid and a base. The correct option is a.
What is neutralization?Neutralization is the reaction that occurs when acids and bases of equal strength react to generate salt and water. Because acid and bases cancel each other out, the salt generated in the reaction is neutral.
Neutralization is the reaction of an acid and a base that causes the pH to rise to 7. It is a useful process that occurs in everyday life, such as the treatment of acid indigestion and the addition of lime to acidic soil. Neutralization lowers the pH of alkali to around seven.
Taking a base helps to neutralize excess acid in our stomach. Because formic acid is present in the ant sting, it can be painful. Using moist baking soda, which is basic in nature, we can neutralize the acid action and reduce the discomfort caused by the sting.
Therefore, the correct option is a, action between an acid and a base.

Some behaviors, such as nest building in birds, are determined by the genes of an organism. These innate behaviors are inherited from parent to offspring and exhibited even if the offspring does not observe its parent performing the behavior. Nest building behavior was most likely an evolutionary advantage because birds that built nests were more likely to raise their young to maturity and thus increase their reproductive success. That is, birds that laid their eggs in nests had more offspring survive to adulthood than those that did not. Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a species due to+
Answer:
natural selection
Explanation:
According to the evolutionary theory, natural selection can be understood as the process of differential survival and reproduction of individuals due to phenotypic differences, which may be associated with different colors, sizes, behaviors, etc. The only prerequisite is that these phenotypic differential traits must be heritable, which means that they must be passed by genes from one generation to the next. For example, in the white-throated sparrow, it has been discovered two morphs that differ in behavior due to a chromosomal inversion in sex chromosomes.

Answer: If a land fertilizer were used on the algae it would severely damage the plant and suffocate it.
Explanation: Fertilizers are used by homeowners to maintain and improve landscape beauty and quality. In recent years, increased use of home lawn and garden fertilizers has caused concern about pollution of lakes and groundwater. Proper fertilizer application can enhance plant growth without polluting the environment. Yet, misuse of fertilizer may not only harm the environment—especially ground and surface water—but may in fact result in injury to landscape plants as well. The nutrient phosphorus harms clear, free water by creating algal blooms. This process, known as eutrophication, turns the water green, clouds the water, causes odor problems, and depletes the oxygen for fish and other species, effectively suffocating them.
Answer:
Well knowing that most fertilizers help algae grow, my prediction is that the algae expectantly grow at a high rate. The rain would also help the growth and might even get the algae in the water systems.

Select an ecosystem that is familiar to you and describe the biotic and abiotic factors that exist there?
Answer:
Forest Ecosystem
An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.
Biotic Factors by Type
The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:
shrubs , flowering plants , ferns , mosses , lichens , fungi , mammals , birds , reptiles , insects , worms , microbes
Abiotic Factors by Type
The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.
Biotic Factors by Function
Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.
These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.
These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.
Abiotic Factors by Function
The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).
Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.
An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.
What is a Grassland Ecosystem?
A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.
The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.
Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.

Orchids are flowering plants that dependent visa punishment a pol a population of orchids in a rain forest has reached its carrying capacity rainforest be population is a limiting factor in the orca population what will happen to the orchids caring capacity of the rainforest
Answer:
Explanation:
The question is incomplete below is the correct version of the question.
Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases? A. The carrying capacity will not change because it is a constant property of a species. B. The carrying capacity will not change because it is a constant property of an ecosystem. C. The carrying capacity will decrease because the level of the limiting factor decreases. D. The carrying capacity will increase because the level of the limiting factor decreases.
Answer :C. The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
The carrying capacity of a system is how much population an habitat can sustain depending on the available resources without leading to competition. This resources include food, water, space.
Since Rain forest bee is a limiting factor for orchid therefore Orchid population is dependent on the Rainforest bee's population so a decrease in the bee's population will lead to a decrease in the orchid population.
This will then lead us to a decrease in the carrying capacity of the system due reduction in the population of the limiting factor the bee because carrying capacity is population dependent.

Answer:
Ok:
Explanation:
The woman eats and digests food to get glucose while the plant can undergo photosynthesis which forms glucose.
The plant and the woman utilize different mechanisms for accumulating glucose in their body to use for energy.
What is Glucose?Glucose may be defined as the main type of sugar in the blood which provides immediate energy to the body's tissues to perform metabolic activities.
Plants utilize the process of photosynthesis to construct their food
(glucose) with the help of carbon dioxide and water in the presence of sunlight, while the woman eats food products which are then digested into the stomach, and glucose is synthesized which is then transported into the bloodstream.
