not getting enough sleep, because the body only makes energy for exercise while asleep
not getting enough sunlight, because cells need sunlight to function

What happens next after the ribosome reaches the start codon?
A. Peptide bonds between amino acids are broken.
O B. The ribosome detaches from the amino acids.
C. TRNA molecules attach to codons.
D. The ribosome finds the stop codon.
Once the ribosome reaches the start codon, the next step in protein synthesis is the binding of a complementary tRNA molecule carrying the appropriate amino acid to the codon, which is option C.
What is translation in proteins?During translation, the ribosome reads the codons in the mRNA strand, which specify the sequence of amino acids that will be assembled into a protein. The ribosome does this by binding to the mRNA at the start codon (usually AUG), which indicates the beginning of the protein-coding sequence. Once the ribosome is positioned at the start codon, the first tRNA molecule carrying the appropriate amino acid binds to the codon via complementary base pairing between the codon and the anticodon of the tRNA.
Hence, the next step in protein synthesis is the binding of a complementary tRNA molecule carrying the appropriate amino acid to the codon, which is option C.

5. Balanced forces cause a change in the motion of plate tectonics. True O False
Answer:
False, they do not cause a change
Explanation:
Balanced forces will cause no change in the speed of an object. Balanced forces acting on an object in opposite directions and equal in strength, as shown in the arrows below, do not cause a change in the speed of a moving object. Objects that are not moving will not start moving if acted on by balanced forces.
The plant cell's central vacuole Group of answer choices occupies a large area of the cell All choices are correct is a reservoir for water. Stores nutrients and cellular waste products.
Answer:
Stores nutrients and cellular waste products.
Explanation:
Vacuole is a space that is line with membrane and within the cell that lacks cytoplasm but filled with fluid.
They are important cytoplasmic organelles and perform certain functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
In plant, large central vacuoles enable them to attain a large size without accumulating the bulk that would make metabolism difficult.

Is Salmonella maintaining? Why or why not? Plz help
Answer and explanation:
No, because most people are infected with salmonella by eating foods that have been contaminated by the s-word. Since our society is much more industrialized, we are cleaner when it comes to making food. Salmonella is mostly found in dirtier countries such as third world countries. Obviously, other food-borne illnesses are out there, but salmonella is not as common anymore, since we are improving.

Write a paragraph explaining how energy flows through an ecosystem.
Be sure to use the following terms:
Energy Pyramid Sun
Trophic Level Producer,
Primary Consumer Decomposer
Secondary Consumer Tertiary Consumer.
Answer:
The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
How energy flows through an ecosystem is summarized below.
Energy flows through an ecosystem in the following order:
Sun ----> Producer ---> Primary consumer ---> Secondary consumer ---> Tertiary consumer ---> Decomposer.
Some of the energy from the sun is fixed by the producer through a process known as photosynthesis. The producers are usually green plants and photosynthetic bacteria.Primary consumers feed directly on the producers.Secondary consumers feed on the primary consumers.Tertiary consumers feed on the secondary consumers.The decomposers feed on the remains of the tertiary consumers.As the energy flows from producer to the different consumers, and to the decomposer, only about 10% of the energy available in each trophic level move to the next with the rest being lost to heat.
Hence, an energy pyramid is created as we move from the lower trophic level to higher trophic levels.

Answer:
What happens during DNA replication?
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
