1. Isovolumetric relaxation.
2. Ventricular filling.
3. Isovolumetric contraction.
4. Ventricular ejection.
5. Ventricular filling.
6. Ventricular ejection.
7. Isovolumetric contraction.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole: in this stage, the ventricles is relaxed and would be filled with blood. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.The following terms describe the physical or mecahnical events with the correct phases of the cardiac cycle in mammals (human beings).
1. Isovolumetric relaxation: All 4 cardiac valves are closed and all 4 chambers are relaxed during this phase.
2. Ventricular filling: The maximum amount of blood is in the ventricles at the end of this phase.
3. Isovolumetric contraction: The pressure in the ventricles is higher than in the atria, but lower than in the arteries, during this phase.
4. Ventricular ejection: The semilunar valves are open and the AV valves are closed during this phase.
5. Ventricular filling: The atria contract at the end of this phase.
6. Ventricular ejection: The pressure in the ventricles is higher than the pressure in both the atria and the arteries during this phase.
7. Isovolumetric contraction: Systole begins with this phase.
What is chemosynthesis?
• How do chemosynthetic organisms get energy? Some examples of organisms include colorless sulfur bacteria, iron bacteria, and giant tube worms (Riftia parchyptila).
Answer:
By making reactions between elements or compounds.

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification portion below, the definition of the topic is mentioned.
Explanation:
This shows that the distinctions between people living in a culture or geographical region are often based on ethnicity including ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair color, body potential for heat resistance, and menu variety. In something like a specific race or ethnic group, these social traits bring them alongside, and the young government associated with a particular race is often obligated to answer the custom practiced by individuals related to such a particular demographic. These are assumed that understand the connection to a specific community follow these rituals only to solve difficulties they have previously faced due to errors perpetrated by certain ancestors.Based on what you have learned in this activity, will you share the link to that article on

what role does energy play in changing particle motion?
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
Explanation:
What part of the cell determines the type and order of the amino acids that make up a protein?
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.

1.Gravity is
found only between the earth and the moon
not found in space, but is only found on earth
a pulling force that exists between all objects in the universe
a force that pushes objects away
2.Which statement is true about a planet’s orbital motion?
Orbital motion results when the object’s forward motion is balanced by a second object’s gravitational pull.
Orbital motion is limited to the moons of the planets and the planets in our solar system.
Orbital motion cannot be achieved with man-made objects.
Orbital motion only occurs when forward motion exceeds the gravitational pull.
3.How does distance affect the gravitational force?
The gravitational force decreases as distance increases.
The gravitational force is not changed by distance.
The gravitational force changes unpredictably with distance.
The gravitational force increases as distance increases.
4.As mass increases, the gravitational force
changes unpredictably
decreases
stays the same
increases
Answer:
The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.

Which statement best describes the initial process of N-linked glycosylation in the endoplasmic reticulum
Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
