The correct answer is selective breeding.

The selective breeding is a technique, in which the animals or plants of a desired trait is selected an bred, in order to obtain the desired trait in the progeny.

The technique of selective breeding is very ancient, even it was used by Mendel in his pea plant experiment. With the advancement in the techniques of biotechnology, hybridization, cloning, and recombinant DNA technology was developed.

<span>the oldest form of biotechnology is : selective breeding
  biotechnology included all kind of efforts that we use to obtain a desired genetic result from the reproduction of a certain organism. In the early years of biotechnology, we still hasn't developed a way to do genetic manipulation, so we do selective breeding to obtain our desired result</span>

What do the offspring look like?
Nina [5.8K]

Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. Plants and animals, including humans, resemble their parents in many features because information is passed from one generation to the next.

1.Three<span> major </span>types of RNA<span> are mRNA, or messenger </span>RNA<span>, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal </span>RNA<span>, that serve as </span>structural<span> components of protein-making </span>structures<span> known as ribosomes; and finally, tRNA, or transfer </span>RNA<span>, that ferry amino acids to the ribosome to be assembled 
2.</span>Transcription<span> is the </span>process<span> by which DNA is copied (</span>transcribed<span>) to mRNA, which carries the information needed for protein synthesis. </span>Transcription<span> takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
3.</span><span>n molecular biology and genetics, </span>translation<span> is the </span>process<span> in which ribosomes in a cell's cytoplasm create proteins, following transcription of DNA to RNA in the cell's nucleus. ... In </span>translation<span>, messenger RNA (mRNA) is decoded by a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide.
4.</span>DNA is the genetic holder in our body ! for any message DNA has to convert in RNA and then protein resulting in all the traits we have !
so on transcription DNA information is converted to RNA and during translation into protein .... thus these protein helps in building our appearance , our Personalities every thing !

so we can say DNA influence physical trait !

Excitation-contraction coupling links two physiological processes. what are these two processes and what constitutes the critica
luda_lava [24]

The link where the action potential of the nerve that meets muscle and causes it to contraction is where excitation-contraction coupling occurs. The  T_tubules the invaginate into the sarcolemma of the muscle cells are the ones that carry the excitation into the muscles. Its depolarization causes the lateral sacs of the sarcoplasmic reticulum to release ca2+ ions. The ca2+ then bind into their site on troponin and causes the tropomyosin to shift and allow actin to expose the binding site in which myosin head will bind and form a cross bridge that is important in the contraction of the muscle.
