Experiment #1: Plants
A certain plant has white flower petals and it usually grows in soil that is slightly basic.
Sometimes the plant produces flowers with red petals. A company that sells the plant
wants to know if soil pH affects the color of the petals in this plant.
Design a controlled experiment to determine if soil pH affects petal color. In your
experimental design be sure to:
• state the hypothesis to be tested in the experiment
• state one way the control group will be treated differently from the experimental group
• identify two factors that must be kept the same in both the control group and the
experimental group
• identify the dependent variable in the experiment
• state one result of the experiment that would support the hypothesis
The pigments that give fruits, vegetables, and petals their colors, such as chlorophyll, carotenoids, and anthocyanins, are heavily influenced by pH.
What is a good pH level for soil?
Vegetables, grasses, and most ornamentals thrive in slightly acidic soils (pH 5.8 to 6.5). Soil pH values outside of these ranges may result in less vigorous growth and nutrient deficiencies. Primary, secondary, and micronutrients are the three types of nutrients needed for healthy plant growth.
The color of flower petals is influenced by the pH of the soil.
A portion of the control group will be planted in soil that is mildly basic.
The experimental groups will be planted in pH-neutral soil.
The acidic soil will be used to raise the experimental group.
The non-acidic soil will be used to raise the control group.
Plants that grow in slightly acidic soil produce red blooms, while plants that grow in slightly basic soil produce crimson blooms.
Therefore, pH has a significant impact on nutritional qualities such as water-holding capacity and the color of petals, which are enhanced in acidic environments.

Smooth Endoplasmic Reticulum (ER) - lipid synthesis, calcium ion storage and poison detoxificationRough Endoplasmic Reticulum (ER) - protein synthesisGolgi apparatus - cisternal maturation and protein modification and sortingLysosomes - Macromolecule digestion and autophagy.What is the endomembrane system?
Membrane bound organelles that modify, package and move macromolecules such as proteins and lipid molecules in eukaryotic cells are collectively known as the endomembrane system. The various functions of the endomembrane system are:
1,) Protein synthesis: This occurs in the rough endoplasmic reticulum. It contains ribosomes, which help to synthesize secondary structures in proteins.
2.) Protein modification and sorting: This is also done in the rough endoplasmic reticulum. The flattened membrane disks and cisternae perform protein modification.
3.) Lipid synthesis: The smooth endoplasmic reticulum in the liver produces steroid hormones like testosterone and oestrogen from other steroids and lipids.
4.) Macromolecule digestion: This happens in the lysosome. The lysosome is highly acidic and contains enzymes that aid in macromolecule digestion.
5.) Autophagy: This is the process in which damaged cells and protein are eaten or damaged by the lysosome. The macromolecules are broken down and reused by the cell.
6.) Cisternal maturation: It takes place in the Golgi apparatus.
7.) Calcium ion storage: Calcium ion is stored in the smooth endoplasmic and is secreted into the cytosol when it's needed.
8.) Poison detoxification: The smooth ER in the liver detoxifies substances from digestion. It does this by removing the lipid part and making the substance hydrophilic in order to be excreted by the body.

Each biochemical reaction involves a specific enzymes to facilitate the change from reactants to products. What property of enzymes allows for the specificity? Explain. HURRYYY PLEASE
Every biochemical reaction involves a specific enzyme to facilitate the change from reactants to products. The property of the enzyme that allows for specificity is because different enzymes have differently shaped active sites.
The shape of the active site of an enzyme is reciprocal to the shape of its specific substrate. This simply means that they are the correct shapes to fit together and function.
Enzymes are highly specific, I.e. a particular enzyme can catalyse a particular reaction only.
Enzymes show different types of specificity as follows:
1. Bond Specificity: This is also called relative specificity. The
enzymes are specific for a bond here.
2. Group Specificity: This is also called structural specificity.
The enzymes are specific to a group here.
3. Substrate Specificity: It is also called absolute specificity. In this, the enzyme acts only on a particular substrate.

According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognisable differences are the result of changes made by subsequent generations.
Is evolution a hypothesis or a proven scientific fact?Scientists would have to work hard to come up with a natural alternative explanation that could explain everything that evolution now explains as well as the new facts that questioned it, even if evolution were hypothetically rejected or contested by new data. It is true that evolution is a widely accepted scientific theory.
A sound justification for such data is a scientific hypothesis. The evidence for evolution comes from transitions in the fossil record, defects in animals that represent previous shared ancestry, and observable evidence of contemporary processes.
A well considered explanation for observations of the natural world that has been developed through the scientific process and that combines several facts and hypotheses is known as a theory.

blue eyes are a type of eye color also known as what?
The color of the eye depends upon the amount of melanin present in the front layer of iris. Less melanin is responsible for blue eyes.
What is blue eye colour ?The part of the eye that has color is called the iris. The pigmentation of the iris, often known as the colored part of the eye, determines the color of the eyes. Irises can be purchased in one of six distinct hues, including amber, blue, brown, gray, green, hazel, or red.
Blue eyes feature stroma that is entirely colorless and devoid of any pigment whatsoever, in addition to lacking any further collagen deposition. As a direct consequence of this, the color blue is produced as a result of the Tyndall effect since all of the light that penetrates it is refracted back into the atmosphere.
Therefore, blue eyes have a very low melanin content, making them more susceptible to photophobia.

membrane? In what type of cells (1 plant cell modification and 1 animal cell modification) would we
expect to see each type of modification?
The two cell surface modifications we can expect to see on the outside of the plasma membrane is a signaling molecule, or ligand.
What is Receptors and ligands?Receptors and ligands come in many forms, but they all have one thing in common: they exist in closely aligned pairs, with a receptor recognizing only one (or a few) specific ligands, and a ligand binding to only one (or a few) target receptors. Binding of a ligand to a receptor changes its shape or activity, allowing it to transmit a signal or directly produce a change within the cell.
Plasma membrane receptors are membrane-anchored proteins that bind ligands on the outer surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. Therefore, many different types of molecules (including large, hydrophilic or "water-attracted" ones) can act as ligands.
