7 0
The three mechanisms which regulate the heart are endocrine, cardiovascular and Sinoatrial nodes.
The endocrine system consists of the glands and hormones of the human body. The cardiovascular system is the organ system which is responsible for the circulation of the blood around the body and the oxygenation of the body's tissues. The sinoatrial node (SA node) generates the electrical impulses and is considered the natural pacemaker of the heart.

What happens to the CO2 released by the body?
Sladkaya [172]

Answer:

When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.

Gemiola [76]

The plasma membrane of the enveloped alga cell serves as the source of the apicoplast's second outermost membrane.

<h3>Where did all chloroplasts come from?</h3>

Chloroplasts were first established in eukaryotes through an endosymbiotic relationship with a cyanobacterium; they later spread through the evolution of eukaryotic hosts and the subsequent engulfment of eukaryotic algae by formerly nonphotosynthetic eukaryotes.

<h3>How did eukaryotic cells develop mitochondria and chloroplasts?</h3>

Chloroplasts and mitochondria most likely developed from engulfed bacteria that once existed as autonomous organisms. An aerobic bacterium was eventually swallowed by a eukaryotic cell, which later established an endosymbiotic bond with the host eukaryote and gradually transformed into a mitochondrion.

Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
