Answer:

Translation

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

What chemical formula reflects the diagram
Elden [556K]
Chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulas can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulas.

Elenna [48]
Type 1 stools are detached, hard lumps that be similar to nuts that are tough to pass. Type 3 stools are like a sausage, but with pops on the surface. Type 5 stools are mushy blobs with clear-cut ends that are passed effortlessly. Type 6 stools are cottony pieces with raggedy edges.

Where does cellular respiration begin
Arlecino [84]

Answer:

cytoplasm

Explanation:

Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

What are some of the conditions that the cell must regulate in order to maintain homeostasis? Do
Drupady [299]

Answer:

to maintain homeostasis these things must be controlled:

  • pH levels in the body (I.e. the stomach)
  • wanted levels
  • sugar levels
  • level of Co2 in our bodies
  • blood glucose levels
  • body temperature

we maintain homeostasis to ensure that our enzymes, which speed up or make chemical reactions are working well and work within he required conditions.

external things we can do to maintain homeostasis:

  • wearing the appropriate clothing in summer and winter
  • consuming the correct temperature beverages (i.e. cold drinks in summer)
  • consumitn the correct temperature and nutrient required foods (I.e. nutritious pumpkin soup in winter)

we also shiver when we are cold - the friction between our muscles produces heat.

1.How does being made of many cells help large organisms maintain homeostasis?
Ugo [173]

Answer:

1.Small cell: has larger surface-area to volume ratio  

  Bigger Cell:  has little space to volume ratio

   

2. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.

Amoeba and some bacteria's are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.

Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.

3. Diffusion and Cell Size

The larger a cell is, the greater the surface area available for diffusion. ... Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
