In which order will free nucleotides add on to a single strand of DNA with the sequence ATTGCA during DNA replication?
AnnZ [28]
The answer is T A A C G T.

Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced.  Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C). 

So, free nucleotides will add in the following order <span>T A A C G T:
original strand                 new strand
     A                                       T
     T                                       A
     T                                       A
     G                                      C
     C                                      G

In which scenario could natural selection most obviously occur?
3241004551 [841]
<span>Natural selection is likely when there are stronger selection pressures. For example, a perpetual selection pressure is the fact that organisms have to compete for food and resources, meaning the best adapted ones survive. However, a stronger selection pressure may cause natural selection to occur more obviously. An example of this is when the number of white peppered moths decreased during industrialization in England due to the soot collecting on the trees. The change in population was very fast and obvious.</span>

Hydroelectric dams are often used to generate
inysia [295]

Answer:

Potential & Kinetic energy.

Explanation:

The water used gains potential energy overtime before it is converted to mechanical (or kinetic energy). This can be explained by the water having increased potential energy as it flows at an equal altitude, but converting to kinetic energy as it flows downhill, or over the dam.

This kinetic (or mechanical) energy is then converted to traditional electricity. This process is also an example of a renewable resource being utilized for everyday things (such as powering cars, homes. or charging batteries).

Muscle contraction is an example of which of the following types of work? Group of answer choices electrical concentration heat
Citrus2011 [14]

Answer:

Muscle contraction is an example of mechanical contraction.

Explanation:

Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.

Muscle contraction is based on force and length.

The process of skeletal muscle contraction is an energy requiring process.

In order to perform mechanical work,actin and myosin  utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.

In a working muscle,glucose is released  from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
