Explain how in an electrical system like wires going from a plant to a house, there is less electrical energy at the end of the

chain (the outlet in the house) compared to at the plant. How does this connect to, contradict or explain the law of conservation of energy which states that energy cannot be created nor destroyed. The answer should be 10-15 sentences long.

Answer:

According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant. A simple example involves a stationary car at the top of a hill.

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.  The only way to use energy is to transform energy from one form to another.

Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. ... For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.

What binds to the prokaryotic chromosome to start dna replication?
Scorpion4ik [409]

Answer:

DNA Helicase

Explanation:

The process of DNA replication is very complex and requires a variety of proteins in the form of Enzymes.

The DNA replication starts at the site which is about 245 base pairs long and is rich in AT sequences called Origin of replication. The origin of replication recognised by an enzyme called DNA helicase which breaks the hydrogen bonds present between the bases and unwinds the DNA. The RNA primase enzymes then synthesizes an RNA primer which gets attached and to which DNA polymerase binds and add nucleotides.

Thus, the first enzyme that binds to the DNA is DNA helicase.

I need help on this question in biology and biology is hard and confusing
Yuliya22 [10]

Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.

What are tissues??<br>and what are cells?​
Slav-nsk [51]

Answer:

Tissues-

Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others.

Cells-

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
