Answer:
1) Organisms in this domain can be unicellular or multicellular - Eukarya
2) Organisms in this domain are unicellular and are often found in extreme environments - Archaea
3) Organisms in this domain have cells that contain a nucleus - Eukarya
Explanation:
All living organisms were classified into a large group consisting of three types of organisms called DOMAIN. It is the highest taxonomic rank of organisms. The three domains that life was classified into are: Archaea, Bacteria and Eukarya.
The domain Archaea contains organisms that are unicellular and prokaryotic i.e. they do not have a membrane-bound nucleus. The organisms in this domain are characterized by their ability to survive in harsh environmental conditions e.g hot temperatures etc
The domain Bacteria also consists of unicellular and prokaryotic organisms. They contain cell walls in their cells made up of peptidoglycan unlike domain Archaea and Eukarya.
The domain Eukarya consists of organisms that are both unicellular and multicellular and strictly eukaryotic i.e. possess a membrane bound nucleus that houses their genetic material. They are divided into Kingdoms: Protista, Plantae, Animalia and Fungi.
Answer: Your answer would be A
Explanation:one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
The expansion of the aorta causes a rise in blood volume and blood pressure.
<h3>What is the cardiac cycle?</h3>
Heartbeat pattern The cardiac cycle includes all of the physiological processes connected to a single pulse, including the electrical, muscular (pressures and volumes), sensory, and other activities. During each cardiac cycle, both ventricles and atria beat alternately.
<h3>Briefing:</h3>
The human heart's cardiac cycle includes two phases: ventricular relaxation and atrial contraction. The right ventricle has low pressure when the right ventricular systolic pressure is frequently less than 30 mm Hg. The left ventricle has a thicker wall and more muscle mass than the right ventricle as a result of the blood flowing at a high pressure. The expansion of the aorta causes a rise in blood volume and blood pressure.

Answer:
Epithelial cells
Explanation:
Epithelial cells are cells that secret mucus to prevent friction between organs. Like between the Heart and Lung.
Explanation:
Free amino acid do not have a peptide bond , as the amino acid act as a monomer which multiplies and linked via peptide bond to generate protein chain .
A free amino acid have a carbonly group (- COOH ) and a -NH₂ group .
The formation of protein chain require at least two amino acids linked via peptide chain .
The role of peptide chain only comes in case of protein , because it acts as a linking species .
Hence , free amino acid does not have any peptide chain .
