This is called activation energy
The cell membrane is composed of a phospholipid bilayer. Because it is made of lipids, they are non-polar molecules. That means that other non-polar molecules can easily pass through. In addition to other non-polar molecules, small, uncharged molecules like water, glycerol, ethanol can also pass through without the use of channel or carrier proteins. <span />
<span>Lamarck believed that organisms could acquire characteristics during their lifetime, that they could pass down to their offspring, but Darwin did not believe these traits could be passed down. Darwin proved that the species adapted to their environment through natural selection. Meaning only the one that could adapt to the changes would survive. </span>
Answer:
The correct answer is- Nirenberg and Heinrich, 1961.
Explanation:
Experiments by Marshall Nirenberg and Heinrich Matthaei in 1961, began to decipher genetic codes and state about the 64 triplet codons in the genetic code by using mRNA from DNA to translate into specific amino acids in our biological system.
Their experiment helps to decode or crack the code of DNA by establishing the first codon out of 64 triplet codes which are UUU codes for phenylalanine. In the future, the same approach is used to find other amino acids.
Answer:
The correct answer would be elongation.
Cell elongation is defined as the lengthening of a cell during differentiation of a cell. It takes place during growth of an organism or during movement in mature plants.
In plants, it is primarily regulated by light and plant hormones like auxin.
Auxin modifies the structure of the cell wall which helps the cell to elongate.
