The process of translation involves three main types of RNA, including mRNA, tRNA, and rRNA, working together to decode information from DNA and build proteins in the ribosomes.
During the process of translation, mRNA decodes information from the original DNA master plan to build proteins in the ribosomes. This process involves three key types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). The mRNA carries the genetic information copied from DNA in the form of a series of three-base code words, each of which specifies a particular amino acid.
The tRNA molecules act as adapter molecules, each able to carry a particular amino acid and recognise the appropriate codon in the mRNA. Through a series of steps, the tRNA molecules bind onto the mRNA and add their amino acid to the growing chain of amino acids that ultimately forms a functional protein.
Last but not least, the rRNA molecules come together with particular proteins to form a functional ribosome that facilitates the assembly of the amino acids into the new protein.

Answer:
Health
Explanation:
Our health is usually affected as a result of the physical environment. This supports the popular saying of a clean physical environment being the best avenue for good health in organisms.
When there are lots of contaminated substances and pollutants in the atmosphere, the health status of the organism is affected and it causes a decline.

Photosynthesis:
Respiration:
photosynthesis: C6H12O6 = 6 O2 + 6 CO2 + 6 H2O
breathing: C6H12O6 + 6 O2 6 CO2 6 H2O ATP
Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and oxygen (O₂).

The four macro molecules are nucleic acid, carbohydrate, proteins, and lipids.
Structure:
1. Nucleic acids: Contain N in rings, nucleotides made of sugar, phosphate and nitrogenous base
1. Carbohydrates: Made of C,H, and O; –OH's on all carbons except one
2. Lipid: Made of C,H, and O; lots of C-H bonds; may have some C=C bonds (unsaturated)
3. Protein: Contain N, have N-C-C backbone
Function:
1. Nucleic acids: Stores and transfers info
2. Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall
3. Lipid: Insulator and stores fat and energy
4. Protein: Provide structural support, transport, enzymes, movement, defense.
The 4 types of Macromolecules:
- Carbohydrates: Compound made of Carbon, Hydrogen, and oxygen. Their main functions are for Energy, Storage, and structure. There are 3 types of carbs; Monosaccharides, Disaccharides (Which are both simple sugars), and Polysaccharides (Which are starches).
- Lipids: Compound that contains mostly carbon and hydrogen. Their main functions are to store energy, Insulate the body, surround and protect cells, regulate cell activity, and provide structure and Transmit information. They are well known as Fats (solid at room temp.) & oils (Liquid at room temp.) phospholipids, and Steroids.
- Proteins: Compound made of Carbon, Hydrogen, and Nitrogen. Their main functions are for transport, making movement possible, providing structure and support, and speeding up chemical reactions.
- Nucleic Acids: Compound made of Carbon, Hydrogen, oxygen, nitrogen, and phosphorous. Their main function is to store and transmit genetic information, determine protein structure, and helping in building proteins. They are the blueprint for life. They include DNA and RNA, and they determine your appearance.
Answer:
pupils
Explanation:
When we step out into bright light, the pupil will contract, reducing the amount of light entering into the eye and protecting our retinas, as well as allowing us to see more clearly. The reason we blink and screw our eyes up in this situation is that this change in pupil size isn't instantaneous.
Answer:
Your pupils
Explanation:
When you all of the sudden go into a bright light, your pupils become smaller to adjust to the brightness. When you go back to a less dark space, your pupils will enlarge.
b. they exhibit the same basic cell wall.
c. they perform the same mode of reproduction.
d. they have dna within their nucleus.
Answer;
D. they have DNA within their nucleus.
Explanation;
-According to evolutionary theory, diverse groups of animals evolve from one or a few common ancestors and the mechanism by which this evolution takes place is natural selection.
-Natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population.
-All forms of life are built of cells. A cell is the basic unit of the structure and function of living things. Living things may appear very different from one another on the outside, but their cells are very similar.
