The enzyme tryptophan synthetase is produced sizes, large and small. Some mutants with no enz tivity produced exactly the same size enzymes as the wild type. Other mutants with no activity produced its the large enzyme; still others, just the small enzyme.
a. Explain the different types of mutants at the level of protein structure.
b. Why do you think there were no mutants that produced no enzyme?
Answer:
Due to changes occur in the protein structure.
Explanation:
The different types of mutants produced at the level of protein structure because mutation changes the protein structure of organism which leads to different types of mutant organisms. There were no mutants that produced no enzyme because enzymes are the most important part of the body in order to help the organism in their survival. These enzymes speed up the process of chemical reaction.

Would would be the possible gamete combinations?
Answer:
1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr
Explanation:
The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.
Which of the following is formed last in daughter cells when plant cells divide?
The nucleus
The nuclear envelope
The cell membrane
The cell wall
Answer:
The cell wall is formed last

State your claim. Make sure your claim fully explains how infrared photography can be used to visualize temperature differences
Answer:
Infrared thermography using an infrared camera is the most popular technique for detecting surface temperature without contact. ... Passive thermography measures relevant temperature differences of the surface by heating it with lamps (heat sources).
It is well known that sugars glucose and fructose are the primary fermentable substrates. However, malic acid can also be fermented but to lactic acid rather than ethanol. This is especially important in red wine, why?
Answer:
The correct answer is - due to the different bacteria that produce a different enzyme that is involved in the fermentation of malic acid.
Explanation:
In red wine production, malic acid in present in grapes converted to a softer lactic acid. This process is known as malolactic fermentation. It takes place due to the presence of different types of bacterias such as bacteria of the lactic acid family.
These bacterias produce enzymes which is used to convert the malic acid to lactic acid such a process can occur naturally also.
evidence of evolution on comparative embryology
Answer:
Scientists have used comparative embryology to study and gather evidence of evolution. Karl Ernst von Baer, a Russian scientist, made observations on embryos of different species and came up with four principles of comparative embryology: 1. General features of an embryo appear before specialized features.

What are the strengths and weaknesses of a cell model
I know the weaknesAmong the weaknesses of a cell model is the inability to reflect the role of complex decision by human agents. However, cellular frameworks may be combined with Markov model, in which transition rules are treated probabilistically and may be conditioned by central lags in cell response.
Answer:
The cell model clearly shows all the processes involved, and it’s easy to understand, even if a person isn’t familiar with the process. The actual cell diagram doesn’t show all the organelles, so it’s an inaccurate representation of the cell. It also doesn’t show all the RNA involved in transcription and translation.

Answer:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom.

You have one parent (P1) of the F1 generation. The other parent (P2) is a mystery but can be determined by the results of the offspring, the F1 generation. Given your results in the F1 generation, what were the two most likely genotypes of the P (P1 and P2) generation
Answer:
P1 = GGBB ( purple stem with green leaves )
P2 = GGyy ( purple stem with yellow leaves )
Explanation:
Determine the two most likely genotypes of the P ( P1 and P2 ) generation
From table :
purple stem with green leaves occurs 90% ( dominant trait )
Green stem with green leaves occurs 30% ( recessive trait )
let : G = purple stem , g = green stem , B = green leaves, y = yellow leaves
Hence the two most likely genotypes of P1 and P2 are :
P1 = Purple stem with green leaves – GGBB (P-90%, F1-60%) ( from table attached below )
P2 = Purple stem with yellow leaves – GGyy (P-10%, F1-10%) ( from table attached below )

can Earth's magnetic field reverse ? if so , how often does it happen and how would we notice
Explanation:
This much is undeniable. Based on the magnetic fingerprints locked into ancient rocks, we know that over the last 20 million years, magnetic north and south have flipped roughly every 200,000 to 300,000 years (this rate has not been constant over the planet's lifetime, though).
This could weaken Earth's protective magnetic field by up to 90% during a polar flip. Earth's magnetic field is what shields us from harmful space radiation which can damage cells, cause cancer, and fry electronic circuits and electrical grids.
Living organisms are commonly divided into six kingdoms: archaea, bacteria, fungi, protists,
plants, and animals. What’s the biggest problem with classifying organisms in this way?
they may be in the same category but they don't have the same biological makeup
The biggest problem in classifying organisms this way is that the way is not well-defined and diverse and if any organism doesn't fall into another kingdom that is added to these kingdoms.
What is classification?Organisms are classified into groups and classes on the basis of their characters and structure. It helps in identifying and understanding the diversity of living organisms.
The six kingdom classification is based on similar characteristics like cell type, and food. Before this, scientists divide the organism into plants and animals.
Thus, The major issue with this system of classifying creatures is that it is not well-defined and diverse, and if an organism does not fit into one of the existing kingdoms, it is added to those already there.

which direction do new york state weather systems usually approach from
Answer:
west to east
Explanation:
The weather system of New York moves in the west to east direction. It is driven by the jet stream which moves from west to east.
The jet stream is nothing but the normal trade winds that blows in and around the equator and move from west to east. While very strong wind forces start blowing from east to west due to the tropical trade winds
