Answer:

B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.

Explanation:

Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.

When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence. For example, given the code:

GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.

So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.

Answer: The answer is 2200 calories per day for Zondra and 3000 per day for Austin

Explanation:

The options are;

a. 1800 calories per day for Zondra and 2200 per day for Austin

b. 2200 calories per day for Zondra and 3000 per day for Austin

c. 2400 calories per day for each of them

d. 2000 calories per day for each of them

The answer is option B -2200 calories per day for Zondra and 3000 per day for Austin

Calories provide energy which we use to perform daily activities. The calories derived from food allow us take part in important activities and leisure. Calorie needs are often higher during teenage years because it is the time of rapid growth.

Austin, is her 16 year old son. The recommended calorie needs for adolescent males between the ages of 16- 18 are; 2,400 calories for non active adolescents, 2,800 calories for moderately active adolescents and 3200 calories for active adolescents.

Zondra is a 14 year old female adolescents. The recommended needs for adolescent females between the ages of 14-18 are; 1,800 calories for non active adolescent females, 2,000 calories for moderately active and 2,400 calories for active adolescent females.

Option B, 2200 calories per day for Zondra and 3000 per day for Austin fall within the range

which of the following explains the most likely effect of this toxin on the light reactions of photosynthesis?

ivanzaharov [21]

Answer:

Which of the following explains the most likely effect this toxin will have on the Calvin cycle? Carbon dioxide will not be converted into carbohydrates. The toxin inhibits RuBisCO from catalyzing the joining of carbon dioxide with RuBP. This prevents carbon fixation, so the Calvin cycle will not occur.

What type of pressure means the air around you is densely packed?.

uranmaximum [27]

In the atmosphere, the density of air particles decreases with height, with more gas particles remaining near the surface of Earth. When only taking into account humidity, dry air is more dense than moist air because of molecular weights of the gases.
