Air Pollutants can be Reduced by following various methods:

Answer:

(B) biological activity

Explanation:

The processes that change the boulder and cobbles to soil are weathering and biological activity. Weathering is the process in which the weather breaks down rocks into smaller pieces and particles, whether if it is from water, air or living organisms. Various biological processes help facilitate rock fragmentation. Between them we may find the roots of the trees that eventually pull rocks apart, we find how animals walk through the rocks making them disintegrate, and finally, we find some organisms that release chemicals that help break rocks.

The correct answer is (B). The processes that change the boulder and cobbles to soil are weathering and biological activity.

Weathering is the process by which rocks are broken down into smaller pieces and eventually into soil. This can occur through physical means, such as the freeze-thaw cycle, or through chemical means, such as the reaction of rocks with acidic rainwater. However, biological activity also plays a significant role in the weathering process. Organisms such as plants, lichens, and burrowing animals can break down rock through physical disturbance and chemical secretions.

Let's consider the other options:

(A) Metamorphism - This is a process that changes the mineralogy and texture of rocks through heat and pressure, typically deep within the Earth's crust. It does not produce soil but rather transforms one type of rock into another.

(C) Cementation of sediments - This is a process that occurs after sediments have been deposited. It involves the precipitation of minerals in the spaces between sediment grains, which can cement them together to form sedimentary rock. This process does not break down rocks into soil.

(D) Melting of rock material - This process, known as igneous processes, involves the melting of rock to form magma or lava, which can then cool and solidify to form igneous rocks. Melting and solidification do not contribute to the formation of soil.

Therefore, biological activity is the process among the options that directly contributes to the breakdown of boulders and cobbles into soil through weathering.

The arrows in a food chain show the flow of energy, from the sun or hydrothermal vent to a top predator. As the energy flows from organism to organism, energy is lost at each step. A network of many food chains is called a food web. ... The trophic level of an organism is the position it holds in a food chain

In a food chain or food web, energy and nutrients move from one organism (producer) to those that consume them (consumers and decomposers), forming a cycle.

In a food chain or web, energy and nutrients move from one organism to another. It starts with the producers (such as plants) that get their energy from sunlight through photosynthesis. Then, the primary consumers or herbivores (creatures that eat plants like rabbits, deer etc.) consume the plants and obtain their energy. Following this, the secondary consumers or carnivores (animals that eat primary consumers like foxes, eagles etc.) get their energy. Finally, decomposers (organisms that consume dead plants and animals, like fungi and bacteria) break down the dead organisms and return the nutrients back to the soil, completing the cycle.

Biological evolution is the process by which populations of organisms change over time. How could natural selection lead to the evolution of a species?

Answer:

1) Respiratory rate and pattern

2) Respiratory cycle

3) Lymph flow occurs

4) Venous pooling

Explanation:

This question centers on the topic: Respiratory rate and pattern. When respiration is mentioned, the activities mostly acknowledged to it are breathing in and out which are made possible by the contraction and relaxation of the skeletal muscles and the lungs. Ventilation can be said to be normal when the inspiratory expansion and expiratory contraction of the muscles of the chest, occur without efforts and is mostly automatic.

The Respiratory rate and pattern can be observed when the frequency of the inspiratory phase is noted because this phase is active and very easy to count. Also, taking into account the number of breaths taken per minute, is referred to as the Respiratory rate. Observation of the respiratory rate and taking into consideration the inspiratory expansion of the chest cage is done during the respiratory cycle. Two groups of muscles known for the activities of inspiration and expiration while contracting and relaxing, produce a rhythmic respiratory rate and pattern. Lymph flow which occurs during hyperventilation has stopped. A venule is a small blood vessel which is in the microcirculation that accepts deoxygenated blood to return from capillary beds to veins. Venous pooling which is the Venous return of blood and lymph.

Final answer:

The respiratory pump, driven by the rhythmic changes in thoracic pressure during breathing, enhances venous return during hyperventilation and diminishes it during hypoventilation.

Explanation:

The student's question pertains to the influence of breathing rate on the venous return of blood and lymph. The contraction and relaxation of the skeletal muscles of breathing cause rhythmic changes in thoracic pressure while breathing, and this cycle is referred to as the respiratory pump. This action increases during hyperventilation, enhancing venous return of blood and lymph. The action of this mechanism decreases during hypoventilation, diminishing venous return of blood and lymph.

Biogeographic isolation refers to the separation of the members of the similar species, or a group of organisms, which breed and generate offspring that can further give rise to young ones.  

The separation can be achieved by the geographical forces like oceans, rivers, and mountains, and by the biological forces, like hunting times, and spring or fall mating.

Final answer:

In the phrase 'organic waste only on the compost bin,' the word 'organic' refers to biodegradable materials that come from living organisms, suitable for composting to create humus, a soil improver.

Explanation:

Definition of Organic Waste:

The term organic in relation to waste refers to materials that are derived from living organisms. In the context of a compost bin, organic waste would include things like food and kitchen waste, green waste like leaves and grass clippings, as well as other biodegradable materials derived from plants and animals. These organic wastes are typically broken down by microorganisms in the composting process to form humus, a nutrient-rich material that can improve soil quality and provide essential nutrients to plants.

It's important to distinguish organic waste from inorganic or non-biodegradable waste, which includes items like plastics, metals, and glass. Only biodegradable waste should be placed in a compost bin since these materials can naturally decompose and reintegrate with the earth, providing environmental benefits such as soil enhancement and reduction of methane emissions from landfills.

Organic fertilizers, like those made from composted organic waste, offer a host of benefits to the ecosystem and agriculture. They deliver nutrients more slowly than synthetic fertilizers, improve soil structure, and promote biodiversity in the soil. This makes them appealing for those seeking to farm or garden in a way that is more aligned with natural ecosystem processes.

Answer: Input of energy

Explanation:

The necessary reactant for a chemical reaction to take place is the input of energy. The reactants combine together in order to get the desired product.

This reaction cannot be carry forward without the supply of energy. This is because energy is required to start a reaction. This energy is known as the activation energy.

so, in order for any reaction to proceed there must be a proper input of energy.

Most of the terrestrial diversity is found in tropical forests and in general, land has more species than the ocean; some 8.7 million species may exists on Earth, of which some 2.1 million live in the ocean.

Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

Amazon represents the quintessence of biodiversity, the richest ecosystem on earth.

The right answer is The Amazon region (due to its forest)

The Amazon rainforest is an equatorial forest located in the Amazon basin in South America. The Amazon basin covers 7.3 million km² and the forest itself covers about 6 million km², located in nine countries.

The Amazon rainforest is a tropical rainforest with the world's largest biodiversity (it has more species than the rainforests of Africa or Asia).

Final answer:

The statement that mutations always negatively impact a population is false. Mutations can be beneficial, harmful, or neutral, affecting an organism's fitness in different ways. Neutral mutations sometimes play a role in the long-term evolutionary changes of a population.

Explanation:

The statement that mutations always negatively impact a population is false. While it is true that many mutations are harmful, changing a functional allele to a less or nonfunctional one, some mutations have beneficial effects, such as increasing an organism's fitness. Moreover, many neutral mutations have no immediate effect on an organism's fitness but may still play a role in the long-term evolutionary process.

Advantageous mutations can lead to improved survival and chances of reproduction, as seen with the mutation that conferred insecticide resistance in mosquitos or the black coloration in peppered moths during the Industrial Revolution. Harmful mutations, on the other hand, can decrease an organism's fitness by reducing its likelihood of survival or the number of offspring it can produce. However, the evolutionary impact of mutations cannot be oversimplified; neutral mutations and those with only a slight effect can, over time, contribute to significant genetic diversity within a population.

Empty calorie is term used for food with high amount of calorie but have little to none nutrient. This food will give energy but not giving the nutrient that the body need to be healthy. Typical food would be the one with high sugar or fat content. Consumption of empty calorie food will provide more calorie, make the person easier to gain weight.

Overprocessing food is the biggest cause of empty calories in American diets. The various steps in the process of industrializing food add a number of artificial preservatives and other chemical stabilizers that are unhealthy if consumed in excess, plus added sugar, salt and fat to help remove most. of the nutrients that a food would have if consumed fresh.

Answer is option A. nucleotides

Answer:

(A). Nucleotides

Explanation:

The nucleotides are the basic unit in formation of DNA and RNA. The both nucleic acids contain nucleotides with different nitrogenous bases. The nucleotide consist of ribose sugar, phosphate and a nitrogenous base.

The ribose sugar is present in the RNA and deoxyribose in the DNA. In the absence of phosphate group, the ribose sugar and nitrogenous base forms a nucleoside.

The monosaccharides is formed by just bounding of C, H and O.

Monosaccharides are simplest molecule or unit in the carbohydrates group which united with each other to form di, tri or polysaccharide structure. As these are the simplest unit in carbohydrates, they are only formed by numbers of carbon, oxygen and hydrogen atoms. The number of atoms in the chain of monosaccharides varies with changing required compound. for example in deoxyribose, one of hydrogen is not present in its structure but present in ribose.

Dolphins and dog fish have a similar body shape due to analogous traits from adapting to similar aquatic environments, not because they are closely related on an evolutionary level. They do share a more remote evolutionary history as both are vertebrates. The Phylogenetic tree helps illustrate this separate evolutionary background.

Despite the similarity in body shape between a dolphin and a dogfish, they are not closely related from an evolutionary point of view. Dolphins are mammals while dogfish, or as commonly known, a type of shark, are fish. This implies different evolutionary paths. The dolphin is a mammal that has re-adapted to marine life

and this has led to a similar body plan due to environmental factors, a concept referred to as analogous traits.

Both dolphins and fish are, however, vertebrates, indicating a more remote shared evolutionary history. This, in part, contributes to their similar body shape. But the likeness in terms of body shape does not envision a recent common ancestor but instead is a display of similar adaptations in response to comparable aquatic environments. The morphological similarity is more as a result of convergent evolution.

This is further corroborated by the Phylogenetic tree, an evolutionary tree that shows the order of evolutionary events and the order in which certain characteristics evolved. It clarifies that dolphins and dogfish have separate evolutionary backgrounds, meaning that they are not as closely related as one might initially assume based on external appearance.

The correct answer is: D.  damage to nerves that control the stomach.

The vagus nerve is a cranial nerve that controls stomach contractions and thus, the movement of the food. When the vagus nerve is damaged, the muscles of the stomach do not function properly, so gastroparesis occur. Consequently,  food then moves slowly or even totally stops moving through the digestive tract.
