Answer the following questions.
What is the difference between a physical change and a chemical change?
What kind of change occurred in each test? What evidence do you have to support your decision? Be brief, but be sure to defend your conclusion with data.
FIRST PERSON TO ANSWER GETS BRAINLY
1. A physical change occurs when the chemical composition of a substance does not change, but only its physical properties. An example of this would be melting ice. A chemical change occurs when the chemical composition of a substance is altered. An example of this would be the formation of rust from iron.
2. In order to answer this I would need to see what tests the question is referring to.
But you could find one physical change and one chemical and use something like this:
Test 1:
A physical change occurred in Test 1. This is supported by the fact that the substance retained its original chemical composition but changed its form.
Test 2:
A chemical change occurred in Test 2. This is supported by the fact that a new substance was created which had a different chemical composition than the original substance.
Do red blood cells have heterochromatin?
Yes, red blood cells have heterochromatin. Heterochromatin is a part of eukaryotic genomes responsible for gene expression DNA Repair and replication.
Differentiation of Erythroid to mature red blood cells(RBC) is done by multiple erythropoietin operated by signal transduction pathways, this process is also called terminal erythropoiesis. During this process chromatin gradually condenses which is critical for red cell terminal differentiation and final enucleation.
Therefore, the deciphered red blood cells could gain more space for hemoglobin development and flexibility to pass through terminal capillaries.
Chromatin exists in two forms euchromatin, is less condensed, and can be duplicated whereas heterochromatin, is highly concentrated and is typically not duplicated.

6. Use your understanding of the Big Idea to explain which cell below converts the most food into energy and why. Justify your answer
Answer:
The plant cell converts the most food into energy because it contains chloroplasts, which are organelles that are responsible for photosynthesis. Photosynthesis is the process in which plants use light energy from the sun to convert carbon dioxide and water into glucose. This glucose is then used as an energy source for the cell. The other cells do not contain chloroplasts and therefore cannot conduct photosynthesis, so they are not able to convert as much food into energy.

If a solution is 8% solute, it is [x]% solvent
If a solution is 8% solute, that means 8% of it (or 8/100ths) is made up of the stuff you added to it. We know that the whole solution is 100%. Therefore, we need to subtract 8% from 100%, which gives us 92%. We know this is correct since you can't have a less than 100% solution, since it exists wholly.

Mutation may or may not affect the phenotype.
Cause: Point Mutation
Effect A: Altered Splice Site
Effect B: Lack of Regulation
Effect C: No Change
Effect D: Non-Coding Regions
Effect E: Premature Stop Codon
What is Mutation?
Mutation is the process of changing the genetic material of an organism. It is the basic process of evolution, and it can occur naturally or be artificially induced. Mutations can be beneficial, neutral, or harmful, and they can affect a single gene, multiple genes, or the entire genome.
A mutation can affect the phenotype, or visible characteristics, of an organism by changing the expression of a gene or by altering the structure of a gene product. Some mutations can have severe effects on an organism’s phenotype, while other mutations may have no noticeable effect. In some cases, a mutation may lead to a change in an organism’s phenotype without changing the underlying genetic code. For example, a mutation in a gene that regulates the expression of other genes may lead to a change in the expression of those other genes, resulting in a change to the phenotype.

VSEPR stands for Valence Shell Electron Pair Repulsion. It is a model that predicts the geometry of a molecule based on the number of electron pairs present around the central atom. A lone pair is a pair of electrons not shared between two atoms and is represented by two dots in a Lewis dot structure. Examples of compounds with lone pairs include water (H2O), ammonia (NH3), and sulfur dioxide (SO2).
The molecular shapes without any lone pairs are linear, trigonal planar, tetrahedral, and trigonal bipyramidal. The general formula without any lone pairs is AXn, where n is the number of atoms bonded to the central atom. Examples include CO2 (linear), BF3 (trigonal planar), CH4 (tetrahedral), and PCl5 (trigonal bipyramidal).
The molecular shapes with lone pairs are bent, trigonal pyramidal, T-shaped, and square planar. The general formula with any lone pairs is AXnE, where n is the number of atoms bonded to the central atom and E is the number of lone pairs. Examples include H2O (bent), NH3 (trigonal pyramidal), IF3 (T-shaped), and XeF4 (square planar).
What is a Covalent bond?
A covalent bond is a type of chemical bond formed when two atoms share a pair of electrons. This type of bond is generally formed between two non-metallic atoms, such as two oxygen atoms, or between two different elements. Covalent bonds are strong, stable, and tend to form molecules.

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.
