Annelids are one of the organisms that has a systematized circulatory system and is closed.

The circulatory system serves to provide and deliver nutrients and oxygen throughout the organisms cells and tissues. The heart serves as the pumping organ and the cornerstone of the circulatory system.

A restrictive respiratory disorder is characterized by a. inspiratory wheezing. b. expiratory wheezing. c. increased total lung

harkovskaia [24]

Answer: Option D

Explanation:

Restrictive lung disease or disorder are the condition of the extrapulmonary, or parenchymal respiratory disease that resists the expansion of lungs.

This leads to decrease in the lung volume, inadequate ventilation and decreased lung volume and increased work of breathing.

It is also characterized by the decreased residual volume. In this case the amount of air is not expired out completely due to restrictive respiratory disorder.

Explain how to change the physical states of the substance

Mashcka [7]

Answer:

We can change the physical state of a substance by heating or cooling it. For example, liquid water can be heated to convert it into the gaseous form i.e steam. Steam can be cooled or condensed to convert it into liquid water.

Liquid water can be cooled to convert it into the solid physical state which will be ice. Ice can be heated to convert it into liquid again. Hence, we can change the physical states by heating or cooling a substance.

Can someone explain the process of RNA editing?

Talja [164]

The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:Substitution editing and Insertion/deletion editing.

Substitution editing is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:

*Cytidine Deaminases that convert a C in the RNA to uracil.

*adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.Thus a CAG codon (for Gln) can be converted to a CGG codon (for Arg).

*Insertion/deletion editing is the insertion or deletion of nucleotides in an RNA.

These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.
