Horses have three basic coat colors: red (or chestnut), bay, and black. All the colors are controlled by the interaction of two genes, Extension (E) and Agouti (A). The following combinations produce bay color: EE/Aa, Ee/Aa, EE/AA, Ee/AA. Only two produce black color: EE/aa, Ea/aa. Other combinations of the alleles of these genes plus mutations of others result in many possible coat colors and patterns in horses
Coat color in horses is an example of which type of inheritance?
(1 point)
A. polygenic inheritance
B. dominant inheritance
C. Mendelian inheritance
D. recessive inheritance
Answer:
A. Polygenic inheritance
Explanation:
When the qualities or the attributes are passed from the parent to their progeny is called inheritance. It can be passed either sexually or asexually.
The correct answer is:
Option A. Polygenic inheritance
This can be explained as:
When a trait is regulated by two or more genes is called polygenic inheritance.Dominant inheritance occurs when the qualities from the parent possessing the dominant gene pass to the progeny.According to Mendelian inheritance paired genes assorts independently and are passed from parent to their progenies.Therefore, coat colour in horses is an example of polygenic inheritance.

Explain how a school bus uses all of these energy types.
-Mechanical
-Chemical
-Electrical
-Thermal
Answer:
Mechanical
94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.
Chemical
school bus uses petroleum as chemical potential energy.
Electrical
An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again
Thermal
They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.

what did humans evolve from I am creating a a evolution chain I know this can be considered a unintelligent question I am just not positive on what we evolved from
Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Human evolution is not linear manner it is a web, in the process of evolution primates lead to the emergence of homo-sapiens, which is distinct from the hominid family.
How did humans evolve?Human evolution is observed in a web manner not linear in evolutionary history primates lead to the homo-sapiens which is distinct from another family of hominids.
The hominid family includes great apes that diverged from the gibbons 15-20 million years ago. Evolution involves some studies, genetic studies, and h behavioral studies.

How much water on Earth is salt water?
Answer:
97 percent
Explanation:
Science
Answer:
below
Explanation:
Over 97 percent of the earth's water is found in the oceans as salt water. Two percent of the earth's water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth's water available to us for our daily water supply needs.
What is the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C?
Answer:
The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.
We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.
If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.
The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.
Explanation:
The relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.
Psychrometer:
It is a device that use to calculate the relative humidity and dew. It has two thermometer, one measures the dry temperature while another measures the wet-temperature.
Given here,
Dry-bulb temperature is 26°C
Wet-bulb temperature is 18°C
The difference between temperature of wet and dry bulb is
= 26 - 18 = 8°C
Now compare the temperature difference to the chart given in the
Therefore, the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

Suggest reasons for the color patterns of the frog and its lack of color on the ventral surface.
Answer:
To save itself.
Explanation:
The color patterns of the frog and its lack of color on the ventral surface allows the frog to protect itself from their predators because the frog changes its colour and the predators are unable to see them. The color patterns of frogs and their lack of color on the ventral surface allow frogs to escape from their predators. If the frog does not change its colour, the predators will see them and the frog will be catch by its predators and feed on them so this is the reason that frog changes colour or the presence of colour patterns.
