Answer:
A
Explanation:
Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.
Why water is considered as actual renewable?Water would be considered an actual renewable. A renewable resource is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as wood, paper and leather.
Non renewable energy comes from sources that will run out or will not be replenished in our lifetimes-or even in many, many lifetimes. Non renewable energy sources are fossil fuels: coal, petroleum, and natural gas.
Potential renewable resource, potential nonrenewable resource, and actual renewable resource and actual nonrenewable resource. Water would be considered an actual renewable.
Therefore, Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.

3. Five species of warblers coexist in spruce trees by feeding on insects in different regions of the tree and by using differing feeding behaviors to obtain the insects
4. Niche shift
5. As a result of resource partitioning, certain characteristics may enable individuals to obtain resources in their partitions more successfully. Selection of these characteristics (or characters) reduces competition with individual in other partitions and leads to a divergence of features.6. Two species of finches that live on two different islands have similar beaks, both suited for using the same food supply (seeds). On a third island, they coexist, but due to evolution, the beak of each bird species is different. This minimizes competition by enabling each finch to feed on seeds of a different size.
7. The resources a population uses in the absence of competitors or under ideal circumstances
8. The sum total of the organismâs use of the biotic and abiotic resources in its environment
9. The resources a population actually uses
Answer and Explanation:
A. Character displacement: This refers to the change of a trait or characteristic. Two species that share the same space must develop different characteristics in order to reduce competition and make better use of resources.
5. As a result of resource partitioning, certain characteristics may enable individuals to obtain resources in their partitions more successfully. The Selection of these characteristics (or characters) reduces competition with individuals in other partitions and leads to a divergence of features.
6. Two species of finches that live on two different islands have similar beaks, both suited for using the same food supply (seeds). On a third island, they coexist, but due to evolution, the beak of each bird species is different. This minimizes competition by enabling each finch to feed on seeds of a different size.
B. Competitive exclusion principle: The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies entirely the inferior competitor´s fundamental niche, the superior species has advantages over the other species and monopolizes all the resources. At this point, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs, or get extinct.
1. When two species compete for exactly the same resources (or occupy the same niche), one is likely to be moresuccessful.One species outcompetes the other and eventually, the second species is eliminated
C. Ecological niche: The ecological niche is the synthesis of all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species.
8. The sum total of the organismâs use of the biotic and abiotic resources in its environment
D. Fundamental niche: The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species.
7. The resources a population uses in the absence of competitors or under ideal circumstances
E. Realized niche: The realized niche refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species.
9. The resources a population actually uses
F. Resource partitioning: Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely-, migrates or get extinguished. A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

When prokaryotic bacterial cells undergo cell division, the single circular chromosome replicates to form a second chromosome. This new chromosome, like the original, attaches to the plasma membrane. Next, the plasma membrane pinches inward, and a cell wall forms across the middle of the cell to separate the two chromosomes and form two daughter cells. How does cell division in bacteria differ from mitosis in eukaryotes?

when placed in the same container, oil and water do not mix because
Oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.
What are the characteristics of water?The characteristics of water are as follows:
It is a universal solvent that is polar in nature. It possesses high heat capacity and heat of vaporization. It has properties like cohesion and adhesion. The solid form of water is less dense as compared to its liquid form.Due to differences in their polarity, the molecules of water and oil are not intermingled with each other. Due to this, the polar compounds are dissolved in a polar solvent while non-polar compounds like oil are dissolved in a non-polar solvent. Thus, the molecules of oil will finally stick to each other and are immiscible with water.
Therefore, oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.

Which of the following happens when a phosphate-phosphate bond in an ATP molecule
is broken?
Lysosome contents are released in a cell.
Energy is released in a cell.
Water is transported into an animal cell
Light energy is absorbed in a plant cell.
Answer:
An event that occurs when a phosphate-phosphate bond is broken in ATP is that energy is released in a cell.
Explanation:
Adenosine triphosphate or ATP is the molecule in charge of providing energy to the cell, which is necessary to perform its functions.
The energy contained in ATP depends on the high-energy bonds that bind the phosphate groups to the energetic nucleotide molecule. Through the hydrolysis of ATP, phosphate is separated from ATP, obtaining ADP, and a large amount of energy is released. This energy serves for the cell to perform its metabolic functions.
The other options are not correct because:
Lysosomes act on cellular digestion. Transport of water into the cell occurs by osmosis, through aquaporins. Light energy is absorbed in a plant cell, through photosynthesis.Which of the following statements correctly describes some aspect of protein excretion in prokaryotic cells? a Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane system. b The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes. c Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. d In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. e Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell.
Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.

The diagram above represents an animal cell. What is the function of X?
It controls energy released.
It regulates the transport of materials.
It produces proteins.
It synthesizes cellulose.
Answer:
X in the diagram represents the cell membrane and performs the function of regulates the transport of materials.
Explanation:
The cell membrane, marked with X in the diagram, is a lipid bilayer with hydrophobic properties, which acts as a semi-permeable membrane to the passage of substances.
This membrane, that covers the cell and keeps it isolated from the extracellular space, has the function of controlling or regulating the passage of materials from the extracellular to the intracellular space, as well as the exit of substances from the interior of the cell. To fulfill this function it has several alternatives of transmembrane transport.
The other options are not correct because:
The cell membrane does not control the energy released. Protein synthesis occurs in the rugged endoplasmic reticulum. Cellulose synthesis occurs inside the cell, a process dependent on photosynthesis.Answer: it regulates the transport of materials

g The first phase of the Calvin cycle is the (a)_____ phase. During this phase, a single CO2 molecule located in the (b)______ of the chloroplast gets fixed with (bonds with) a CO2-acceptor molecule called (c)_____ . This is a (d)_____ (number)-carbon molecule, which becomes an unstable 6-carbon molecule once it is carboxylated by CO2. This unstable molecule immediately splits into (e)______ (number) 3-carbon molecules called (f)_____ , which are the products of this phase of the Calvin cycle.
Answer:
a) Carbon fixation phase
b) stroma
c) Ribulose bisphosphate (RuBP)
d) 5-carbon molecule
e) two carbon molecules
f) glycerate-3-phosphate (GP)
Explanation:
In the Calvin cycle (also named C3 cycle or Calvin-Benson cycle), the CO2 is reduced in a cyclic process, where the first stable reaction product is 3-phosphoglyceric acid (3-PGA), a 3-C molecule, and the CO2 acceptor molecule is Ribulose bisphosphate (i.e., Ribulose 1, 5-diphosphate). The CO2 enters the chloroplast by passing through the stomata and diffusing into the stroma of the chloroplast, which is the site where sugar is synthesized. The Rubisco enzyme or RuBP carboxylase catalyzes the first step of the cycle (i.e., the attachment of CO2 to RuBP). The result of this reaction is an unstable 6C molecule, which breaks down into two 3C molecules named glycerate-3-phosphate (GP).

Answer:
-Viruses cannot replicate.
-Viruses do not need to consume energy to survive or regulate its own temperature.
Explanation:

Viruses are not able to replicate or carry out any of the functions of living cells on their own. They rely on the machinery of the host cell in order to replicate and produce new viruses, and they are not able to carry out functions such as metabolism, growth, or reproduction on their own.
Why viruses are considered non-living?Viruses are much simpler in structure than bacteria and other living cells. They do not have a true cell structure or any of the characteristic cell organelles found in living cells, such as a nucleus, mitochondria, or endoplasmic reticulum. Instead, they are composed of a small piece of genetic material (either DNA or RNA) surrounded by a protein coat.Learn more about viruses, here:

Which of the following might help reduce nitrate pollution? Use of synthetic fertilizers often leads to the contamination of groundwater with nitrates. Nitrate pollution is also a suspected cause of anoxic "dead zones" in the ocean. Which of the following might help reduce nitrate pollution? adding nitrifying bacteria to the soil using ammonia instead of nitrate as a fertilizer growing improved crop plants that have nitrogen-fixing enzymes adding denitrifying bacteria to the soil
Answer:
adding denitrifying bacteria to the soil
Explanation:
Denitrifying bacteria refer to microorganisms in soil that carry out the conversion of nitrates in soil to free atmospheric nitrogen.
Nitrogen gas (N2) is ultimately the product of denitrification of soil, however certain intermediate nitrogen species are also formed in the process. Some of these intermediates may include the following sequence of conversion; NO3− → NO2−→ NO + N2O → N2.
The chemical equation for denitrification is; 2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O.

Given enough time, the most likely outcome will be: Group of answer choices The two original species will eventually fuse into a third new species, and disappear. The two original species will remain, and a third new species will appear. Nothing: the two original species will remain, and the hybrids will eventually disappear.
Answer:
The two original species will eventually fuse into a third new species, and disappear.
Explanation:
According to Darwin's theory of evolution, species that are better adapted to their environment have greater chances of surviving long enough to reproduce and pass on these favourable characteristics to their offspring. This is known as 'survival of the fittest'.
The original species lack the resilience of the new hybrid species hence the two original species will eventually disappear and fuse into the third specie.
