Answer:
Electrical energy is energy derived from electric potential energy or kinetic energy. ... Thus, all electrical energy is potential energy before it is delivered to the end-use. Once converted from potential energy, electrical energy can always be called another type of energy (heat, light, motion, etc.).
A teacher modeled part of a DNA molecule using two of these coiled springs. Which part of the DNA was the teacher most likely modeling?
Answer: The part of DNA that the teacher was modelling would be the backbone of DNA.
Explanation:
The DNA is made of double helical structure which is twisted. In the structure of DNA two strands are coiled among each other.
The DNA consists of the nitrogenous bases, phosphate groups and deoxy-ribose sugar.
The backbone of DNA is made up of sugar( alternating )and phosphate group.The nitrogenous bases such as adenine, cytosine ,guanine and thymine are joined to the deoxy-ribose sugar.
This backbone part was part that the teacher was making as a model by using two coiled springs.

A bog is a type of wetland with witch of the following
a. stagnant water
c. warm, slow-moving water
b. only dead plants
d. still, acidic water
Answer:
Still acidic water
Explanation:
A bog or bogland is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens.
Describe the basic process of DNA replication and how it relates to the transmission.
Answer: At the replication fork, the helix unwinds into 2 separate strands.
Explanation: DNA polymerase joins individual nucleotides to produce a new strand of DNA. This makes a brand new strand that is identical to the first. The DNA first replicates its information to ensure it is the same in the new strand.

Michaelis and Menten studied the enzyme sucrase, which uses sucrose as a substrate. Assume that lactose is a competitive inhibitor of sucrase. This could be demonstrated by appropriate kinetic experiments. Think about the kind of data that would be collected in these experiments.On the axes below, show appropriate double-reciprocal plots that would demonstrate that lactose is a competitive inhibitor. Label the axes, and any intercepts with X and Y axes appropriately.The graph can be used to determine whether or Vmax has changed in the presence of lactose. State what it about the graph that allows this, and whether Vmax has changed in the presence of lactose.
Solution :
In the context, Menten and Michaelis were doing a research. They are studying about the enzyme sucrase that can use sucrose like a substrate.
The intercept on the y-axis gives the value of the Vmax.
As the intercept is same for both the plots, Vmax does not change upon the competitive inhibitor of sucrase.
The graph plotted is provided below.
When a red 4 o'clock flower with a white flower, all of the offspring are pink. This type of inheritance is known as:_______ a. codominance b. incomplete dominance c. multiple alleles d. epistatsis
Answer:
b. incomplete dominance
Explanation:
Incomplete dominance is a type of inheritance that does not confirm to Mendel's principles of inheritance i.e it is non-mendelian. Incomplete dominance occurs when an allele of a gene does not completely mask the expression of another allele of the same gene, hence, the two alleles combine to form a heterozygous that is different but intermediate of both parent phenotypes.
This is the case in this question where the red allele (R) of a four o'clock plant is INCOMPLETELY DOMINANT over the white allele (W), hence, they both produce an intermediate pink phenotype (RW), which is a blending of both red and white phenotypes.
Which of the following could be found on either public or private land?
state park
Answer: Mine
Explanation:
The options are:
a. state park
b. single-family residence
c. mine
d. factory
We should note that a state park tht is, a park that belongs to the government would be found in a public land since it belongs to the state.
Also, a single family residence would be found on a private land since it's not a government property. A factory would be found on a private land.
Therefore, the answer is mine as this can be found on either private or public land.

Which is an example of an environmental influence that would most likely result in natural selection?
O The soil in a field always has lots of nutrients, so corn plants in a population can grow quickly. O A fish is bom with a genetic mutation that produces a longer tail, allowing the fish to swim faster than others in the population
O A food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot O The temperature in a lake remains constant, so most of the turtle population survives to adulthood
Answer:
The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
Explanation:
Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.
In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.
In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.
The other options are not correct because none of them show environmental pressure that can lead to natural selection.Answer:
food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.

The answer is MITOCHONDRION
Explanation:
All living organisms need energy at the cellular level to carry out their cellular activities. This energy is obtained by eating food. The energy in food is stored in the bonds of the sugar molecule that is contained in it.
However, via a process called CELLULAR RESPIRATION, the stored energy in food is broken down and used to synthesize a form of energy usable by the cell called ATP. This important process occurs in the organelle called MITOCHONDRION.

How does the process of hydration cause chemical weathering?
A.
Water reacts with iron minerals in rock to form rust.
B.
Moving water transports sediment from rock.
C.
Increased density adds pressure to the molecules in rock.
D.
Acidic water dissolves calcite in carbonate rocks.
Answer:
A. Water reacts with iron minerals in rock to form rust.
Explanation:
Generally, weathering is the process by which rocks are broken down or disintegrated into smaller particles. However, as the name implies, chemical weathering is the weathering facilitated by chemical reactions.
However, there are various types of chemical weathering, of which one is HYDRATION. Hydration is a type of chemical weathering which involves the reaction of water with the chemical constituents of rocks, which eventually disrupt or changes the structure. Therefore, in chemical weathering, water reacts with iron minerals in rock to form rust.

When a person is cut, the injured tissue initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. if this is a positive feedback mechanismwhich of the following must be part of the process? The heart would slow down to cause a drop in blood pressure. Platelets would release signals to stimulate the production of more platelets. Blood vessels around the cut would constrict to decrease the surface area exposed to the platelets. Chemical signals released would cause a decline in platelet production
Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.
Please help I will give BRAINLIEST face the earth
Answer:
It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.
Explanation:
Hope this helps you a lot my boo!
Answer:
The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth
