Answer: James Watson and Francis Crick
Explanation:
In 1953 James Watson and Francis Crick are responsible for determining the structure of DNA. James and Watson proposed that the DNA is made up of a double polynucleotide chains that are twisted around each other to forming a helical structure. The two DNA chains runs anti-parallel in opposite direction to each other. Like the structure of the ladder.
The answer is James Watson and Francis Crick
A physical factor that influences an ecosystem is called an "abiotic factor."
A substrate is a reactant that is catalyzed by an enzyme.
Answer:
Proteins, Liver, Osmotic, Fluid, Into The Blood, Decrease.
Explanation:
Blood is considered a colloid because it contains proteins in the plasma.
Most of these are produced by the liver.
Collectively, these substances exert osmotic pressure and prevent the loss of fluid from the blood as it moves through the capillaries.
The pressure exerted by the plasma proteins is called colloid osmotic pressure.
This force is responsible for moving fluids into the blood and preventing excess fluid loss between blood capillaries and the interstitial fluid.
If plasma protein levels decrease, colloid osmotic pressure will decrease.
I hope this answer helps.
Answer:
one with the fewest number of genetic differences in the nucleotide sequence.
Explanation:
A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.
