BaLLatris [955]

Explanation:

-these are likely different tissue systems or organs

-they each may execute different specified functions

Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Further Explanation:

These tissues form systems that may be

  • meristematic- temporary, found at growth regions called meristems; they are undifferentiated or incompletely differentiated and continuously undergo growth and division
  • non meristematic- permanent tissue, already differentiated and are made up of plant tissue that no longer divides

Meristems differentiate into three main plant tissue types, which make up several  tissues in various amounts:

  • ground
  • dermal
  • vascular tissues

Secondary tissue types are either complex, made up of several different call types, or simple, made up of the same cell type.  Dermal tissue covers the plant's outermost layer, and mediates gaseous exchange. While two types of complex vascular tissue, are the xylem and phloem.

Xylem vessel elements: mature xylem vessel is made up of dead cells called vessel elements aligned end-to-end where these ends have been dissolved and the protoplasm is absent. These form long, continuous tubes that facilitate the unobstructed flow of water and minerals to other areas within the plant.

What<br> are<br> quantative traits reffered to?
zaharov [31]

Answer:

A quantitative trait is a measurable phenotype that depends on the cumulative actions of many genes and the environment.

Explanation:

These traits can vary among individuals, over a range, to produce a continuous distribution of phenotypes. Examples include height, weight and blood pressure.

In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.
stellarik [79]

Answer:

The correct option is d) UAG

Explanation:

Central dogma can be described as the process in which the transcription and translation occurs. The process by which mRNA is made from the DNA is called transcription and the process by which proteins are made by mRNA is called translation.

The first codon present on the DNA is TAG. The mRNA formed from this codon will be AUC. When this mRNA will travel from the nucleus to the cytoplam, the tRNA will bring the anticodons UAG for the first mRNA codon. Hence, the correct option is D.
