If the wild-type codon is ggu, how many single-base substitutions will result in an amino acid substitution? include any changes
SashulF [63]

Answer:

Approximately six

Explanation:

The codon GGU

Single base substitution that will change this codon that codes for glycine to another amino acid includes: a single base substitution in the GGU codon such as GGU- AGU can occur. thus, approximately six single base substitution can take place to change this codon to code for another amino acid. A single base substitution cannot change the codon to a stop codon unless it happens twice or there is more than a single base substitution.

What is special about nitrogen, and what is its main function in the atmosphere
inna [77]
Nitrogen is the most abundant of the gases present in the atmosphere. 78 percent of the atmospheric air comprises of nitrogen, oxygen makes up for 21 percent and all other gases make up for the remaining one percent. Oxygen is a highly flammable gas and in the absence of nitrogen it would not have been possible to utilize this atmospheric oxygen, hence the presence of nitrogen reduces its flammability and also neutralizes the toxicity of other gases. Another way to explain this question is - The vital thing about Nitrogen is that it gives air to people to take in, 78% of the air we take in is Nitrogen and just 21% is oxygen, 1% is different gasses. On the off chance that the air was unadulterated oxygen then everything would be to a great degree flamable, and it would likewise be hurtful to people. Nitrogen assumes a vital part in our lives. Oxygen can be poisonious on the off chance that it was the main gas noticeable all around... Nitrogen is too much critical, else we would all die.... Also, I seek oxygen stays 21% after it can be hazardous. Definitely, you ought to realize that Nitrogen can likewise be risky in A few ways, you can look that up and take in more about it, however at this moment we're looking at something else and I would prefer not to be insignificant by any stretch of the imagination, so I'll simply adhere to the Inquiry on the point as apose to the Entire whole theme. I know I have addressed your inquiry, and I believe this was useful.

Hope this helps

10 points! When looking out of my back door, I see robins, blue jays, finches, crows, hawks and owls all living in the same area
forsale [732]

The possibility for all of the mentioned birds to live all in a same area is because they are all specialized and occupy a certain niche in the food chain, thus not standing in each others ways when it comes to competition for food.

All of these birds have adapted to be able to survive in their respective environment, developing characteristics that will enable them to be superior in something. Through natural selection, the individuals that were performing better, got the chance to mate, thus the offspring was better adapted and stronger in its niche of the food chain.

The robins and the blue jays are birds that are very opportunistic in their food choice, thus giving them greater flexibility and ability to survive, they mostly feed on worms, insects, fruits, vegetables, so they have a big menu.

The finches are specialized in eating nuts and seeds, thus avoiding the competition with the previous two, thus having that food type for themselves.

The owls and hawks are both birds of pray, but the owls hunt mostly at night, while the eagles during the day. Also, the owls prefer to have rodents as their pray, while the hawks are mostly eating other birds, thus not standing in each other's ways.

Lab report on mass and motiom golf ball, rubber ball, plastic ball
Tasya [4]

Answer:

Mass and density in the increasing order among the mentioned balls are as follows: golf>rubber>plastic whereas Motion of rubber ball is higher than of golf and plastic ball due to elasticity of the rubber.

Moment of inertia of the ball is dependent on the mass and velocity of the balls which in turn will determine the motion of the balls. Elasticity property of the rubber ball will help to provide opposite force and can enhance the motion of the rubber ball as compared to golf or plastic balls.
