Jamie is explaining to her classmates that she conducted an experiment over the weekend to see if adding more eggs to a cupcake recipe would affect the taste and texture of her cupcakes. She told her classmates that she noticed her cupcakes were moister and even taller. She said she measured each cupcake and the ones made with 3 eggs instead of two were 0.25-.05 centimeters taller than the ones with only 2 eggs. She also said that the ones with more eggs seemed to be a darker shade than the ones with fewer eggs. Jamie said the amount of eggs didn’t affect how many cupcakes she could make. She was only able to get 6 jumbo sized cupcakes with the recipe even if she added an extra egg. Question: List at least 2 qualitative and 2 quantitative observations that Jamie made in her experiment. (4 points)

Answer:

A. Competition can limit or deplete resources

Final answer:

Competition for abiotic and biotic resources can limit or deplete these resources, affecting their availability in an ecosystem. This can result in harm to competing organisms, influence community dynamics, and alter species distribution.

Explanation:

When organisms and populations compete for abiotic and biotic resources, the impact can be quite significant. Competition can limit or deplete resources, which affects the availability of these resources to both the competing organisms and others in the ecosystem. For instance, plants competing for sunlight, water, and nutrients can reduce the availability of these resources for other species. This competition can harm one or both of the competing organisms, particularly if they are of the same species (intraspecific competition) or of different species (interspecific competition).

An invasive species like kudzu, by competing for light, can outcompete and thus limit the growth of trees. This is an example of how competition can lead to ecological imbalances. In the broader picture, competition impacts not just the individuals directly involved but can also affect community dynamics and the distribution of various species in a habitat.

Considering the options provided, the correct answer is A. Competition can limit or deplete resources.

Answer:

the attraction between objects with mass

Explanation:

as between the sun and the earth.

In the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome sister chromatids that are firmly attached at the centromere region.

Metaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell.

Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

Final answer:

Chromatids form during the S phase of the cell cycle, when DNA replication results in two identical sister chromatids joined at the centromere.

Explanation:

Chromatids are formed during the S phase (Synthesis phase) of the cell cycle when DNA replication takes place. In the S phase, each chromosome duplicates and creates two identical DNA molecules known as sister chromatids, which are connected at a central region called the centromere. This prepares the cell for division, whether it be mitosis or meiosis.

Subsequent stages of the cell cycle involve the movement and separation of these chromatids. During prophase and metaphase, the chromosomes condense and align for division. In anaphase, the sister chromatids are pulled apart to opposite poles of the cell, and during telophase, they arrive at opposite ends, followed by the division of the cell into two daughter cells in cytokinesis.

Answer:

B. It becomes a positive ion.

Explanation:

The number of electrons and protons is eleven in sodium. After sodium (Na) has transferred its electron to the chlorine atom (Cl) it becomes a positively charged ion. This is because as electrons are negatively charged, losing of an electron will increase the number of protons (i.e 11) as compared to the number of electrons (i.e 10) in sodium (Na) atom. Hence, a positive charge will be acquired by the sodium (Na) ions.

Answer:

C. Photosynthesis

Explanation:

Answer:

All

Explanation:

All organisms require some sort of oxygen to survive. Fish have gills that pull the oxygen from the water.

Answer:

Cations, Oxygen, Anions, Hydrogen

Explanation:

Water molecule is polar (meaning it has dipoles). The oxygen having a higher atomic mass attracts most of the electron cloud of the molecule becoming partially negatively charged and leaving the hydrogen end to be partially positive.

An Ionic compound is one between two atoms where one donates its electrons to the other for both to achieve stable configuration. The two atoms, therefore, become charged and are bought together by electrostatic forces.

When an ionic compound is put in water, it dissociates into its ions (anions and cations) They attract and repel with the polar water molecules depending on their charges. The anions (negatively charged ion) are surrounded by water molecules with the hydrogen ends and the cations are surrounded by water molecules with the oxygen ends.

Answer:

Positive sodium ion, oxygen atom, negative chloride ion, hydrogen are the answers

Explanation:

Water can dissolve many solutes. Water molecules are polar; however, it acts differently with charged polar substances. This interaction of water with charged substances forms hydration shell surrounding the solute. So, when the ionic compound NaCl dissociate in water, the hydration shell formation occurs around the ions.

The positively charged Na become surrounded by partially negative charge of the oxygen atom of water molecule and the negatively charged Cl become surrounded by partially positive charge of hydrogen atoms of water.

Explanation:

Alligators generally feed on variety of foods, such as small amphibians, birds, fish etc. To catch these preys, alligators usually disguise by immersing all their bodies inside water with only their eyes and noses showing. They will stay perfectly still in that position until a prey come along, then they will quickly attack the prey.

Alligators are quick and efficient predators. This technique that the alligators used to catch their preys enhances their survival and competition for food.  

In addition, alligators depends on their external environments to regulate their body temperature. They can use sun as well as migration to warmer water to regulate their body temperature.

Answer:

Mass of the substance is 24.426 g.

Explanation:

Given that the density is [tex]0.023g/mL[/tex]

The volume  of substance is  [tex]1062 mL[/tex].

density of a substance is the mass of the substance per unit volume.

density= [tex]\frac {mass}{volume}[/tex]  

In this question the mass of the substance is [tex]0.023g/mL[/tex]    

Therefore the mass of the substance in [tex]1062 mL[/tex] of the substance is given by  

mass = [tex]volume \times density[/tex]

mass = [tex]1062 \times 0.023=24.426 g[/tex]

Final answer:

Using the formula mass = density × volume, the mass of the substance with a given density of 0.023 g/mL and volume of 1062 mL is calculated to be 24.426 grams.

Explanation:

The student has asked to calculate the mass of a substance given its volume and density. The formula to find mass is mass = density × volume. Given that the density is 0.023 g/mL and the volume is 1062 mL, we can find the mass by multiplying these two values:

Mass = Density × Volume = 0.023 g/mL × 1062 mL = 24.426 g

Therefore, the mass of the substance is 24.426 grams.

Answer:

Surface tension due to cohesion

Explanation:

Water molecules are polar meaning they have dipoles. The hydrogen end is partially positive while the oxygen end is partially negative. This is because oxygen with high atomic mass attracting most of the molecule's electron cloud to its end.

Due to this phenomenon water molecules act like little magnets that attract each other. The attraction of the molecules forms hydrogen bonds with each other. This is called cohesion (attraction of similar molecules).  Due to this, water is able to create a surface tension that acts like a ‘skin’ and can support some weight (including its own weight) without collapsing.

Final answer:

The ability to fill a glass with water slightly above the rim without spilling is explained by water's cohesive property and surface tension, resulting from hydrogen bonding between water molecules.

Explanation:

The property of water that allows you to fill a glass to just slightly above the rim without it spilling over is known as cohesion. Cohesion is the result of water molecules being attracted to each other due to hydrogen bonding, which creates a strong intermolecular force. This attraction keeps the water molecules together at the liquid-gas (water-air) interface, forming a dome-like shape above the glass. This cohesive force gives rise to surface tension, which allows the water to hold together and not spill over immediately even when filled above the glass's rim.

Examples of cohesion and surface tension in action include floating a small scrap of paper or a steel needle on water. These objects can float because the surface tension at the water's surface can support their weight without the water breaking apart. Surface tension is the capacity of a liquid to withstand rupture when placed under tension or stress.

Final answer:

Option D) 'It only exists in liquid and solid form' is NOT a unique property of water since water also exists as a gas (water vapor). The other options correctly describe water's high surface tension, its ability as a powerful solvent, and the lower density of ice compared to liquid water, all of which are unique properties of water.

Explanation:

The question asks which of the following is NOT a unique property of water. The options provided touch upon various characteristics of water, but the correct answer is D) It only exists in liquid and solid form. This statement is not true because water can also exist as a gas, namely water vapor. The other options represent some of the unique properties of water:

A) Surface tension: Water has a high surface tension, allowing it to form droplets and enabling insects like water striders to walk on its surface.

B) It's a powerful solvent: Water is known as the universal solvent due to its polarity, which allows it to dissolve many different substances.

C) Ice is less dense than water: This unique property is due to the hydrogen bonding in water, which causes ice to float in liquid water and is critical for sustaining aquatic life in cold environments.

By examining these properties, we can see that option D is the one that is not true about water.

Answer:

The tea with milk and lemon curdles due to the acidic nature of lemon.

Explanation:

Milk is made up of a number of proteins like casein. The proteins in milk are denatured by the addition of lemon juice. When lemon juice is added to tea or milk, the proteins such as the negatively charged casein become neutralized. Now, as no negative charge is present on them so they start to crumple together rather then pushing each other apart. Hence, the clumping causes the milk to curdle in tea.

Answer:

Explanation: All of it is in gamete formation. Meaning, it is going through a gamete formation which also means that pairs of alleles that are for different traits, segregate. They move on independently from one another, never touching.

For your question, It's incomplete dominance which is when cases with one allele isn't complete to be dominant over another allele. It's all got to come together in order for it to become a strong and dominant allele, or else it won't be complete and won't become and do what it has to.

I hope this help you and I hope that I gave you what you wanted/needed for this question.

Final answer:

Two inheritance patterns that differ from simple dominance are incomplete dominance, where neither allele is completely dominant resulting in a blended phenotype, and codominance, where both alleles are fully expressed in the phenotype.

Explanation:

Complex Inheritance Patterns

Not all traits follow the simple dominance inheritance pattern discovered by Mendel. Beyond simple dominance, two other inheritance patterns are incomplete dominance and codominance.

Incomplete Dominance

In incomplete dominance, the phenotype of the heterozygotes is somewhere between the phenotypes of the two homozygous parents. This means that neither allele is fully dominant. A classic example of this is the snapdragon flower, where the cross between a red flower (RR) and a white flower (rr) results in offspring with pink flowers (Rr), a blend of red and white.

Codominance

In codominance, both alleles in the genotype are fully expressed, leading to offspring with a phenotype that is neither dominant nor recessive, but a combination of both. An example of codominance is seen in human blood types, where the A and B alleles are codominant and can result in a blood type of AB.

Answer:

Human disturbances such as clear-cutting can also cause secondary succession. Some disturbances affect only a small area, like the local damage caused by a single tree falling in the forest, while others affect entire landscapes. These disturbances damage the ecosystem but leave soil and nutrients behind.

Explanation:

Trust me.

Compared to primary ecological succession, secondary ecological succession experiences less resource conflicts. In this succession process, the pioneer species also enjoy greater privileges.

Secondary succession starts with a lot of resource availability, primary succession starts with a crisis in resource availability. Major sources of plant energy include decomposing organic matter, inorganic salts, ions, humus, and other soil leftovers.

Pioneer species carry out the establishment or re-establishment process of the sterile or devastated ecosystems at the start of both primary and secondary successions.

Only plants and blue-green algae/cyanobacteria are the main succession's pioneer species; they are all "photo-auto-lithotrophs," or succession producers. Secondary succession pioneer species don't always have to be photo auto-lithotrophic.

Therefore, Compared to primary ecological succession, secondary ecological succession experiences less resource conflicts. In this succession process, the pioneer species also enjoy greater privileges.

Answer:

The correct option is less.

Explanation:

outside an organism's body.

A hypotonic environment can be described as an environment in which the amount of solvent is more outside the cell as compared to the inside of the cell. The amount of solutes is more inside the cell. Hence, water tends to move inwards by osmosis in such an environment.

An isotonic environment can be described as an environment where the concentration of solutes and solvents is the same inside and outside of a cell.

When paramecium caudatum would be in a hypotonic environment, its contractile vacuole will be more active to pump the excess water. In an isotonic environment, there will be no or very less water for the paramecium to pump out of the body. Hence, contractile vacuole will be less active.

A Paramecium caudatum's contractile vacuole becomes less active when the organism moves from a hypotonic to an isotonic environment. This is because in an isotonic environment, there is no net movement of water, so the need for the vacuole to pump out excess water is diminished.

When a Paramecium caudatum moves from a hypotonic to an isotonic environment, its contractile vacuole would become less active since the water concentration inside and outside the cell will be equal, thus, eliminating the need for the vacuole to remove excess water. In a hypotonic environment, water molecules move into the paramecium due to osmosis, causing the organism to swell. As a response, the paramecium's contractile vacuole pumps out water to prevent the cell from bursting. However, in an isotonic condition, the relative concentrations of solute and solvent are equal on both sides of the membrane, which means that there is no net movement of water. Therefore, the contractile vacuole in the paramecium does not need to be as active in pumping water out of the cell.
