Answer:
Explanation:The flow of charge around a closed circuit in the form of electrons is called an electric current. ... So the voltage or potential difference between two points provides the required electrical energy to move charge around a circuit in the form of an electric curent.
Among the Old Order Amish of Lancaster, Pennsylvania, there is an unusually high frequency of polydactylism (extra fingers). Since the group was founded by a small group of separatist German Mennonites in the early 1770s, some 61 cases of this rare trait have been reported, about as many cases as in the entire rest of the world since that time. Given that the trait is inherited, how can you explain the high frequency of this trait among the Old Order Amish
Answer:
A founder effect
Explanation:
A founder effect is a genetic phenomenon caused by genetic drift (i.e., fixation of alleles due to random sampling). A funder effect occurs when a small group of individuals separates from an original population. Due to this separation, some randomly sampled alleles are fixed in the new population, while many other alleles are lost from the original population. Polydactylism is a trait caused by the inheritance of a dominant allele. In this case, it is expected that the frequency for this allele was increased in the original group of separatist German Mennonites, thereby increasing the frequency of the trait in the new population.

Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.
Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Which is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure? A. fossil B. metal C. mineral D. rock
Answer:
C. mineral
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.
2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.
3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.
Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

After a successful launch and return of a rocket, NASA and SpaceX noticed a strange gel like substance on the wing. Under the microscope the strange thing has fibers, but no cells. When introduced to water the substance tends to move around. When exposed to warm temperatures it seems to grow in mass.
nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive

What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.
Answer and Explanation:
An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface. These rings can be cut into various sizes. An oil ring has an axial.

is hair a living thing explain why or why not
Answer:
Hair and nails are not living things they are considered living because they are attached to a living thing but no they are not living.
Explanation:
Hope this helped
Hair is not considered a living thing. Hair is composed of dead cells that are produced by living cells in hair follicles.
Is hair a living thing?Hair is primarily made up of a protein called keratin, which is produced by specialized cells within the hair follicles. These cells, called keratinocytes, undergo a process of differentiation as they move upward through the hair follicle, eventually becoming fully keratinized and forming the hair shaft. Once the hair shaft is fully formed, it no longer possesses any metabolic or cellular activities. It lacks a blood supply, nerve endings, and other cellular structures that are characteristic of living tissues.
While hair itself is not alive, the hair follicles that produce hair are living structures and play a crucial role in hair growth and maintenance. Hair growth occurs in cycles, with each hair follicle going through a growth phase (anagen), a transitional phase (catagen), and a resting phase (telogen). During the anagen phase, the hair follicles actively produce new hair cells, which eventually become part of the hair shafts.

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon atoms can be followed. In an experiment, radioactive CO2 was given for 1 minute to plant cells, and then the cells were examined after 1, 5, 10, 20, and 30 minutes. The following molecules were labeled with radioactive carbon at some point(s): glucose, glyceraldehyde 3-phosphate, glycine (an amino acid), 3-phosphoglycerate, ribulose 1,5-bisphosphate, and sucrose. List these molecules in the order in which they first become labeled.
Answer:
glycine (an amino acid)ribulose 1,5-bisphosphate3-phosphoglycerateglyceraldehyde 3-phosphateglucosesucrose.Explanation:
The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.
Calvin cycle
During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.
During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.
During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.
Cytosol:
Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.
Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.
