Explanation: I think it is stars because there is only one star in our solar system. I don't know for sure if it is, but I think it is. Don't be too sure of my answer.
Well Cyclones are commonly known as lows ,generally are indicators of rain, clouds, and other forms of bad weather. Anticyclones is commonly known as highs ....re predictors of fair weather.
PCR, or polymerase chain reaction is used to take a section of dna and force it into a - millions of identical copies of a DNA fragment
PCR (Polymerase chain reaction) - It is defined as a technique that is used to make millions of identical copies of a DNA fragment in a few hours. This technique is commonly used for a variety of applications like- genotyping, cloning, mutation detection, sequencing, micro arrays, forensics, and paternity testing etc.
Answer:
Griffith concluded that in the presence of the dead S-type pneumococcus cells, some of the living R-type cells had been transformed into virulent S cells. These cells were able to grow in the bodies of the mice, causing pneumonia and multiplying in the blood. ... The DNA alone caused bacterial transformation.
Griffith introduced heat-killed 'S'- strain bacteria Streptococcus in to a mouse along with live 'R' strain bacteria. ... Some 'transforming principle' transferred from the heat-killed 'S' strain had enabled the 'R' strain to synthesise a smooth polysaccharide coat and become virulent.
In this experiments, Griffith injected mice in the lab with live R-type of bacteria. They did not suffer from the disease. ... He thus concluded that heat-killed smooth type bacterial caused a transformation of the living rough type bacteria. This experiment suggested that DNA and not proteins are the genetic material.
Answer:
Active transport
Explanation:
The process of transport of substances that uses energy and carrier proteins of the membrane is called active transport. Amino acids can not cross the hydrophobic core of the membrane and therefore, are transported through carrier proteins. The carrier proteins transport the amino acids using energy and the process is called active transport.
