Write a sientific explanation describing how light ando sound energy help us communicate and share information our daily lives.
Gekata [30.6K]

Answer:  There are many sources of light, but the initial energy for all light sources comes from the sun. Light travels away from its source in straight lines through space as waves of energy. The waves we can detect with our eyes are called visible light. Patterns in the behavior of light are predictable because light moves in waves through space until it comes in contact with an object or material that changes its direction. Light can pass through or bounce off objects. Additionally, different materials can block or absorb light. If an object blocks light, a shadow of the object forms. If the intensity or direction of the light source changes, the appearance of an object’s shadow can change in size, shape, or darkness. Absorbing light energy can cause changes in matter. A common example includes the color of paper or fabric fading as the matter absorbs light over time. Vibrations cause sounds. We can hear when sound waves travel through the air to our ears and cause our eardrums to vibrate. Sound can also travel through other forms of matter, such as liquids and solids.

Describe how the output of the Krebs cycle can be modified in additional processes of the carbon cycle.
Murljashka [212]

Answer:

Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. (Note: carbon dioxide is one carbon attached to two oxygen atoms and is one of the major end products of cellular respiration. ) The result of this step is a two-carbon hydroxyethyl group bound to the enzyme pyruvate dehydrogenase; the lost carbon dioxide is the first of the six carbons from the original glucose molecule to be removed. This step proceeds twice for every molecule of glucose metabolized (remember: there are two pyruvate molecules produced at the end of glycolysis); thus, two of the six carbons will have been removed at the end of both of these steps.

Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD+, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy.

Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA. This molecule of acetyl CoA is then further converted to be used in the next pathway of metabolism, the citric acid cycle.

Using this codon chart, can someone help me give my the mRNA,tRNA,and amino acids from the original DNA sequence “ACT TTC GAT”
nevsk [136]

Answer:

DNA:   ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine

Explanation:

mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.

tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.

Thus,

DNA:   ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)
