Recently there has been a decline in the abundance of life on coral reefs. Scientists are unsure why, but one of the explanations for it is that global temperatures are increasing, making water temperatures rise. These small changes are killing off some of the smallest animals on the reef, which then affects the entire food chain. Which of the following would NOT help protect the diversity of the coral reef?
a: creating coral reefs in cooler waters ?
b: limit fishing around reefs
c : ban places of anchors in reef
d: ban cities into discarding sewage into coral reefs
Limit fishing around reefs would not help to protect the diversity of coral reefs.
What are coral reefs?Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs.
Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.
Coral polyp colonies are bound together by calcium carbonate to build reefs.
According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.
The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.
Hence the correct option is B.

A. incomplete dominance
B. multiple alleles
C. sex-linked trait
D. polygenic traits
Answer:
dissimilar appearence or properties.
Explanation:
Hair color is not so simple as that. Most traits, especially those as complex as color, are controlled by many alleles at many loci. That's why there are different kinds of brown, blond, and red hair in the population. There is no "hair color gene." A fascinating paper came out a few years ago, identifying dozens of SNPs playing a role in hair and eye color. It's a deep, deep rabbit hole that we have only begun to plunge into.

Answer below! : )
Explanation:
Explain 1) The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is dependent on the independent variable. 2) Testing only one variable at a time lets you analyze the results of your experiment to see how much a single change affected the result. If you're testing two variables at a time, you won't be able to tell which variable was responsible for the result. 3) The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group 4) Not sure about this one sorry! 5) hypothesizing, observing, and experimenting. 6) This rule says that where you have one situation that leads to an effect, and another which does not, and the only difference is the presence of a single factor in the first situation, we can infer this factor as the cause of the effect. 7) No matter how carefully observations and experiments are performed, it cannot be ensured that every possible factor is the same in every observation. 8) Munsell Charts are used to provide standard descriptions and names of color. 9) Nitrogen, phosphorus, and potassium. 10) Water table, also called groundwater table, is the upper level of an underground surface in which the soil or rocks are permanently saturated with water. 11) Humus significantly affects the bulk density of soil and contributes to its retention of moisture and nutrients. 12) Texture refers to the size of the particles that make up the soil. The terms sand, silt, and clay refer to the relative sizes of the soil particles. The combined portions of sand, silt, and clay in a soil determine its textural classification. 13) The main difference between sand silt and clay is their particle size. Sand particles are larger in size while clay particles are extremely fine, and silt particles are somewhere in between sand and clay particles. Sand, silt, and clay are the main mineral particles in the soil that affect its texture 14) Mineral matter is derived from the constituents of the parent material. Organic matter. The nature and abundance of iron. Moisture content. 15) In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. 16) Phosphorus is essential for cell division and growth and promotes plant maturation. 17) Aspect of soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration, so well-aerated soil is important for growing crops. 18) The ground above the water table may be wet to a certain degree, but it does not stay saturated. The dirt and rock in this unsaturated zone contain air and some water and support the vegetation on the Earth.

If you reduced three sponge species down to individual cells using a very fine cloth and mixed them together, what would you predict would be the outcome after a period of time? Make sure to identify why, and what proteins are likely responsible.
After a few hours, the cells of each sponge would re-aggregate and form three new sponges.
We can reach this answer because:
The sponge is a multicellular organism with little cell differentiation.The surface of sponge cells has a group of glycoproteins, which allow communication between all the cells in a sponge.These proteins are transmembrane receptors, which emit signals responsible for the cell adhesion process.The cell adhesion process allows the cells in a sponge to regroup if they are separated.In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.

Over 99.9% of the solar system is composed of hydrogen and helium. How does this help to explain the size differences between the terrestrial planets and the gas giants?
Explanation:
Gas giants/Jovian planets are also called the outer planets, they are made of gases, they are large and less dense, more moons. Terrestrial/Rocky planets are also called the inner planets. They are made of rocky surface, denser than Jovians, and small, little or no moons.
The information about the composition of solar system has great significance in providing data about size between the terrestrial planets and the gas giants planets.
The size differences occur between the terrestrial planets and the gas giants due to the presence of different concentration of gases in their compositions. Gas giants planets are also called the outer planets which are made up of gases.
They are large in size but having less density and more moons while on the other hand, terrestrial planets are made of rocky surface. They are also called the inner planets. They are more denser than gas giant planets, small in size and less or no moons so we can conclude that there is a great size differences between the terrestrial planets and the gas giants.
