15. Which factor is density-independent?A. A breakout of disease decreases the size of the frog population inNorthern Minnesota.B. A herd of deer move to the south side of a mountain, joining the herdalready there, increasing competition for food.C. A hurricane severely disrupts a salt marsh in an estuary
Answers
We have to consider that a density-independent factor is a variable that does not depend on how big or how small a population is for it to occur.
In these cases, we could say that the breakout of diseases that decreases the size of the frog population is a density-dependent factor since the disease spread probably for the high amount of individuals of that population's species.
The competition for food we can see in the second case also is a density-dependent factor, since the high number of those deer caused the food resource to be scarse.
Having this clear, we could say that a hurricane that severely disrupts a salt marsh in an estuary is a density-independent factor since this meteorological process would occur no matter if a species population is full of individuals or not.

blue eyes are a type of eye color also known as what?
Answers
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.

14. What are two cell surface modifications that we can expect to see on the external side of the plasma
membrane? In what type of cells (1 plant cell modification and 1 animal cell modification) would we
expect to see each type of modification?
Answers
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.

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
Answers
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.

the answer is antigen
Answers
Any substance that triggers the production of antibodies by your immune system is referred to as an antigen.
This indicates that your immune system is attempting to combat the chemical because it does not recognize it. A substance from the environment, such as chemicals, germs, viruses, or pollen, can behave as an antigen.
Conventional immunoglobulins (Igs) have six complementarity-determining regions (CDRs) in the VH and VL domains that make up the majority of the antigen-binding site. Antibody fragments like Fab and Fv are thought of as an independent unit with a single, complete antigen recognition site.
Your immune system uses antigens as markers to determine whether or not something in your body is hazardous. Viruses, bacteria, cancers, and healthy bodily cells all include antigens.
The three main types of antigen are as follows.
Exogenous (foreign to the host immune system), endogenous (made by internal bacteria and viruses reproducing inside a host cell), and autoantigens are the three basic methods to describe antigen (produced by the host).

The average temperature in San Diego, California is lower as compared to Savannah, Georgia because of the warm ocean currents from the South. Thus, the correct option is C.
What is the effect of Ocean current?Through the moving of heat from the equator toward the poles, ocean currents play an important role in controlling the climate of the globe. Ocean currents are also critically important to the sea life. They carry nutrients and food to the aquatic organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places.
The mixing of warm and cold ocean currents help in replenishing the oxygen gas and favor growth of planktons in the waterbody, the primary food for the fish population. The best fishing grounds of the world exist mainly in these mixing zones of the waterbodies.

Homozygous recessive, homozygous dominant and heterozygous are three types of genotypes.
If a trait tends to be directly passed from parent to child, then the odds are that the trait is a dominant one. If a trait skips generations then the odds are that it is recessive.
