Answer:

B. Anions have more electrons than protons, giving them a negative charge.

and

D. Cations have more protons than electrons, giving them a positive charge.

Explanation:

Anions have negative charge because electrons give negative charges. On the other hand, cations have positive charges because protons have a positive charge and they have more protons.

B. Anions have more electrons than protons, giving them a negative charge.

D. Cations have more protons than electrons, giving them a positive charge.

Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.

Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.

Keith_Richards [23]

The secretion of insulin into the bloodstream is done through exocytosis and absorption through the capillary arteries.

Insulin is a protein required to process sugar. This is a <u>naturally produced protein</u> for which the pancreas is responsible. The insulin Protein is considered a transport protein. It is responsible for carrying glucose from the bloodstream into cells to be used as energy.

This protein is of vital importance. The secretion of this protein is done through exocytosis, which means that after passing through the ribosomes and the Golgi, it is contained within a membrane, which will then fuse into the plasmatic membrane and be released from the cell. It is then absorbed through the capillaries to enter the bloodstream.

Elden [556K]

Given the characteristics mentioned in the question, the animal must be an annelid.

<h3>What is an annelid?</h3>

Annelids, (Phylum name annelida) segmented worms, characterized by having body cavities (or body coelom), mobile bristles (or setae), and bodies segmented by transverse rings. The body cavity is reduced in leeches, and the bristles are devoid of some specialized morphology, including leeches. An important phylum of invertebrates in the animal kingdom, Annelida, consists of more than 9,000 species divided into three classes: Sea worms (polychaetes) are divided into motile and sedentary or tube-dwelling forms. earthworms (Oligochaeta); and leeches (Hildinea). Annelids are coelomic and tridermal.

General characteristics of annelids are:

They show organization at the organ system level.
Your body is segmented.
They breathe through their body surfaces.
The kidney is an excretory organ. They have well-developed circulatory and digestive systems.
Common names for more familiar annelids include earthworms, sandworms, annelids, bristleworms, and leeches.
