Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding

mRNA sequence, that specifies which of the 20 amino acids will be added to the protein during translation.Imagine that a prokaryote-like organism has been discovered in the polar ice on Mars. Interestingly, these Martian organisms use the same DNA → RNA → protein system as life on Earth, except that______

Answer:

In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy . In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid).  For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).

german

Answer:

a. Two of these are correct.

Explanation:

The two correct options are

b. Is a critical component or requirement for wound healing to take place

d. Existing blood vessels give rise or sprout to form new blood vessels

Angiogenesis is the physiological means in which new blood vessels form pre-existing vessels, developed in the starting phases of vasculogenesis. Angiogenesis is a usual and important process in growth and development, wound healing and in the development of granulation tissue.

The growth and maturation of blood vessels is a largely regulated multistep mechanism called angiogenesis.

Sophie [7]

Answer:

Classification system changes because the scientists find new evidence in their studies.

Explanation: The world is always changing and growing and dying as well as developing, so over time things change. For example, as you grow up do you stay the same? No, you notice the physical changes happening, well thats sort of like how the earth and its ways are always changing as well.

Skeletal muscle fibers are classified as ""fast"" or ""slow"" based upon what factor?
andrey2020 [161]

Answer:

Skeletal muscles fibre are classified base on how the produce energy.

Explanation:

Skeletal muscles fibres consist of bundles of cells that form muscles which contain myobrills.

Skeletal muscles are classified based on how the produce energy;

Type 1 or slow pitch muscle fibres are more efficient and last for a long period of time. They are use for postural maintenance or endurance. It use aerobic respiration to produce energy or ATP.

Type 11 or fast twitch muscle fibres use anaerobic respiration and are for short speed and fatigue more easily than type 1.

The level of productivity in oceans can be explained by the fact that ____.
musickatia [10]

The level of productivity in oceans can be explained by the fact that the volume of the global ocean is enormous.

The oceans cover about 70% of the earth. This makes the ocean to occupy the largest volume on earth.

In spite of this large volume, the productivity of the ocean is just about 55 billion tons.

This low productivity of the ocean is tied to its large volume and small amount of primary productivity.

what is defined as the movement of water across a semipermeable membrane from high concentration to low concentration?
Oliga [24]
<span>Osmosis is defined as the movement of water across a semipermeable membrane from high concentration to low concentration. This occurs when the surrounding environment of the cell has a higher water concentration than the cell itself. Osmosis is important in animal cells because it helps in the distribution of nutrients and the release of metabolic waste products. In plant cells, osmosis is responsible for the absorption of water from the soil and the elevation of the liquid into other parts of the plants.</span>
