Answer:

The living things are characterized by seven factors which includes movement, metabolism, respiration, sensitivity, growth, Excretion, nutrition and reproduction. The characteristics which indicates life in given items are as follows:

1. A candle flame: When we light the candle, the size of the flame is small and it grows as the wax melts.

2. Balloon floating in the air: As the balloon is floating it shows movement.

3. Bubbles blown from a bubble wand: It shows growth as well as movement.

The characteristic that shows that they are not alive include none of the three items performs excretion, metabolism and they are not made up of cell.

Though a candle flame, a balloon, and bubbles show some life characteristics like response to environment and growth, they lack the essential traits of life like reproduction, evolution, homeostasis, and the presence of cell structure. Therefore, these objects are not considered alive.

When considering the items in question: a candle flame, a floating balloon, and bubbles blown from a wand, it's important to understand the key characteristics of life: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, regulation/homeostasis, energy processing, and evolution. All these attributes together define life.

An evident characteristic representing life in these items could be the response to stimuli or the environment. For instance, a candle flame flickers responding to the air currents, a balloon floats as it is filled with helium, showing adaptation to the surrounding air density, and bubbles show growth as they are blown larger from the wand. These are aspects of sensitivity to environment and growth.

However, the noted objects are nonliving as they lack the majority of life's crucial traits. They don't reproduce, evolve over time, or maintain homeostasis on their own. Neither do they have cell structure - a fundamental trait of life. Hence, these objects are not considered alive despite their adaptability and responses to changes in the environment.

Human centred world view is the idea that says that humans are the most important species and representative of the earth and can use resources as much as needed.

Explanation:

It also focuses on the benefits and threats of the natural environment to the humans. Earth centred world view says that the nature is available for every species on the earth and the earth is not under our control.

Environmental world view gives us an idea about our role in the environment and our activities that causes positive or negative effect on the environment and also understand how does the world does its function.

Anthropocentric or human-centered worldview considers humans as the most significant entities and permits the use of natural resources to serve human needs primarily. Critics argue this perspective is ethically flawed and unsustainable, suggesting alternatives like ecocentric or biocentric worldviews, where all life has inherent value.

The student is asking about the concept of a human-centered worldview, also known as Anthropocentrism. This concept, found particularly in environmental philosophy, entails humans regarding themselves as the most significant entities in the universe and Judge their actions primarily on the basis of human values and experiences. Anthropocentrism views humans as superior to nature and justifies the use of natural resources to serve mankind’s needs, even if it compromises the health of our planet.

However, critics of this worldview argue that it is ethically flawed and unsustainable, insinuating that other life forms and the natural world are valuable only for their usefulness to humans. Critics present ecocentric or biocentric worldviews as alternatives, where every life form has inherent value and humans are one part of the natural world, not above or outside of it.

Removal of keynote species from an eco-system can lead to the existence  of the system in danger.

Explanation:

There are certain keynote species in the eco-system which has an important role to play in the survival of other species. The removal of these species can put the eco-system in danger. The keynote species helps to maintain the ecosystem by keeping it in harmony.

An ecosystem may cease to exist or can be taken over by a completely different kind of species by breaking the direction of the system if one of its keynote species is removed.

Keynote species can be divided into three groups by scientists-

(i) Predators: helps in controlling the population of the prey species by affecting the numbers of plants and animals in the food web, like- tiger sharks

(ii) Ecosystem engineers: an organism that creates or demolishes a club of species, like- beaver and

(iii) Mutualists: The interaction of two or more species for their own benefit, such as- bees.

A molecule diffuses down its concentration gradient by moving from one region of higher concentration to a region of lower concentration.

The diffusion of a molecules down the concentration gradient means the movement of molecules takes place from the region of higher concentration to the region of lower concentration.

Concentration gradient is the difference in the concentration of a molecule between two regions. Concentration gradient is the force which is responsible for the movement of molecules through the cell.

Transport through cell membrane takes place by two mechanism: Passive and Active. In passive transport, the energy is not required as the movement of molecules occurs down the concentration gradient. The molecules moves from the region of higher concentration to the region of lower concentration through the membrane, thus energetically favorable.

Flatworms, roundworms, and segmented worms are all invertebrates. Some species of each type of worm are free-living, meaning they are not dependent on another organism.Some are parasitic.

Flatworms belong to phylum Platyhelminthes. They do not have a coelom, respiratory system or a circulatory system.Tapeworms flukes are examples of flatworms.

Roundworms are part of the phylum Nematoda. They are bilaterally symmetrical invertebrates.They have a psuedocoelom. Ascaris lumbricodes is the most common human parasite.

Segmented worms are the most complex animals of these three invertebrates. They are placed in Annelida. Segmented worms have a true coelom, a circulatory system and a digestive system.An earthworm is a segmented worm.

Although tapeworms have segmented bodies, they do not belong to the phylum Annelida due to key biological differences. The segments in tapeworms are reproductive and not involved in locomotion or digestion, unlike in Annelids, and their nervous systems are structurally different.

The body of a tapeworm is indeed segmented, but it does not belong to the phylum Annelida because there are key differences in their biological make-up. Annelids, such as earthworms, have bodies made up of similarly structured segments with a central nervous system. Moreover, these segments have the potential to function independently.

On the contrary, tapeworms, which belong to the phylum Platyhelminthes, while they have segmented bodies, their segments don't have an independent functional capacity. In tapeworms, these 'proglottids' are reproductive in nature and not involved in locomotion or digestion like the segments in Annelids. Additionally, their nervous systems are structurally different from that of the Annelida.

A. ENZYMES

Explanation:

Enzymes are the catalysts of reactions found in living things.  Enzymes can be best described as kind of proteins that serve as biological catalysts. They majorly function in increasing the speed of biological reactions by lowering the activation energy . Enzymes do not effect the equilibrium of any reaction. Also, enzymes itself are not used up in any reaction, however transient changes can occur in them due to the reaction. Enzymes are specific for different substrates.

The catalysts of reactions in living things are enzymes. They are proteins that help expedite the rate of chemical reactions within cells. An example is amylase, which facilitates the breakdown of starch into sugars.

The catalysts of reactions in living things are known as enzymes. Enzymes are proteins that significantly speed up the rate of virtually all of the chemical reactions within cells. They achieve this by providing an alternative reaction pathway with a lower activation energy. This function makes enzymes vital for the metabolism of organisms, assisting in processes such as digestion and DNA synthesis.

An example of an enzyme is amylase, which is found in our saliva. Amylase catalyzes the breakdown of starch into sugars during digestion. Without amylase, starch wouldn't be broken down quickly enough to provide the energy our bodies need. Hence, enzymes and their function as catalysts are crucial to various metabolic reactions within living organisms.

Answer:

The original number is -4.

Explanation:

Let the original number be n.

Next, three times the number is equal to 3n.

Then, increased by 4 means 4 is added.

Hence, three times a number increased by 4 equals -8 is written in the equation form as shown below.

=>  3n + 4 = -8

=> 3n = -8 + (-4)

Since the number, 4, goes on the other side of the equal sign, the number positive 4 changes its sign and becomes negative 4, as shown above.

=> 3n = -8 -4

=> 3n = -12

=> n = -12/3

=> n = -4

Checking the above solution.

Three times the number is equal to 3 * (-4) = -12.

The above product when increased by 4 gives the equation as shown.

-12 + 4 = -8.

The result is -8.

This result is same as the result mentioned in the given question, -8.

Hence, the answer that -4 is the original number is correct.

Substances made with hydrogen ions are acidic. Substance made with hydroxide ions are bases. It depends on which ions they are made of.

Answer: Enzymes that perform cellular respiration denature.

Explanation:

Cellular respiration is a process by which cells convert glucose and oxygen into energy in the form of ATP. This process requires the involvement of several enzymes that catalyze the various biochemical reactions involved in cellular respiration. Enzymes are highly specific in their function and are sensitive to changes in temperature and pH.

At higher temperatures above 40°C, the enzymes involved in cellular respiration become denatured, which means that the three-dimensional structure of the enzyme is disrupted. This leads to the loss of its catalytic activity, and the process of cellular respiration cannot proceed at the same rate as before.

Denaturation occurs because the heat breaks the weak bonds that hold the protein structure together, causing the enzyme to lose its shape and function. Once the enzyme is denatured, it cannot catalyze the chemical reactions of cellular respiration effectively, and the rate of cellular respiration decreases quickly.

Therefore, it is important for cells to maintain a relatively constant temperature to ensure that the enzymes involved in cellular respiration can function optimally.

Final answer:

Enzymes that perform cellular respiration denature at temperatures above 40°C, leading to decreased cellular respiration rates. High temperatures cause enzymes to lose their shape and functionality, resulting in inefficient ATP production and a shift to less efficient energy production processes like fermentation.

Explanation:

The rate of cellular respiration decreases quickly at temperatures higher than 40°C primarily because the enzymes that drive the many reactions involved in this process begin to denature. Enzymes are proteins that speed up biochemical reactions, and they have a specific shape important for their function. High temperatures can disrupt the three-dimensional structure of these enzymes, resulting in the loss of their active site and therefore their activity. When these enzymes denature, the efficiency of cellular respiration drops and the cell cannot produce ATP as effectively.

It is also observed that at higher temperatures, such as above 37°C in yeast cells, there is a shift from respiration to partial fermentation. This shift occurs because the increased temperature leads to a decrease in the specific activities of enzymes, constraining metabolism, and when total protein concentration reaches its limit, which cannot increase enzyme activity further, glycolysis becomes more efficient for ATP production despite yielding less ATP per mole of glucose compared to respiration.

While cells can tolerate slight increases in temperature to a certain extent, extreme temperatures, particularly above a threshold of around 40-45°C, can be lethal as enzymes stop functioning correctly. At these elevated temperatures, other physiological changes can also occur, such as altered solubility of gases in blood, which could affect oxygen availability but this is less immediate compared to enzyme denaturation, which has a direct impact on cellular respiration rates.

Answer:

A catalyst decrease the activation energy of a reaction.

Explanation:

The concept of catalyst describes a molecule that has the capacity to increase the rate of a reaction by diminishing the activation energy (minimum energy requiered for a reaction to happen).

A catalyst lowers the activation energy of a chemical reaction, allowing the reaction to happen more quickly.

A catalyst affects the activation energy of a chemical reaction by lowering it. Activation energy is the energy required for a reaction to begin. A catalyst provides an alternative pathway for the reaction to proceed with a lower activation energy, allowing the reaction to occur more quickly.

For example, in the decomposition of hydrogen peroxide, the reaction is slow without a catalyst, but adding a catalyst like manganese dioxide lowers the activation energy, making the reaction happen faster.

The three different shapes of carbon-based molecules are linear chains, cyclic structures, and combinations of both, with geometry influenced by types of carbon-to-carbon bonds and molecular arrangement.

The three different shapes or structures of carbon-based molecules are linear chains, cyclic (ring) structures, and combinations of both. These structures can be seen in various hydrocarbon compounds. For instance, methane (CH4) has a tetrahedral geometry with four hydrogen atoms equidistant from one another, creating a three-dimensional structure critical for the molecule's function. When it comes to the types of carbon-to-carbon bonds, single bonds allow rotation along the bond axis, leading to flexible structures; double bonds result in a planar configuration (as in ethene), and triple bonds create a linear configuration (as in ethyne).

Additionally, the carbon atoms in diamond form a three-dimensional network with each carbon atom connected to four others in a tetrahedral structure. In graphite, carbon atoms form layers of hexagonally connected sheets, with each layer having weak interactions with adjacent layers. Different molecular geometries such as linear, bent, trigonal pyramidal, trigonal planar, and T-shaped also affect molecular shape, as seen with various molecules and polyatomic ions comprising a central atom bonded to two or three other atoms.

The thylakoid membranes are where the light-dependent reactions occur in photosynthesis.

The thylakoid membranes are the site of the light-dependent reactions in photosynthesis. These reactions use light energy to produce ATP and NADPH, which are energy carrier molecules that will be used in the Calvin cycle.

Final answer:

The thylakoid membranes are where light-dependent reactions take place during photosynthesis, capturing light energy to produce ATP and NADPH for the Calvin cycle.

Explanation:

The thylakoid membranes, located inside chloroplasts, are the sites where light-dependent reactions of photosynthesis occur. These membranes house photosystems that contain chlorophyll and other pigments which capture light energy. The light energy is then used to produce ATP and NADPH, two molecules that are essential for the Calvin cycle that occurs in the stroma of the chloroplast. The process overall is critical for converting solar energy into chemical energy that plants, and ultimately all life on Earth, can use.
