Answers

Answer:

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 part of the cell determines the type and order of the amino acids that make up a protein?

Answers

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.

What is Cell division?

Cell division is the process by which a parent cell divides into two new daughter cells. Cell division usually occurs as a part of a larger cell cycle in which the living cell grows and replicates its chromosome before undergoing division.

Cell division occurs in living cells through mitosis and meiosis. The cell division occurs through karyokinesis and cytokinesis. Cell division is a part of the cell cycle. Cell cycle is divided into different phases such as G1 phase, S phase, G2 phase, and M phase.

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?

Answers

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.

The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions.
1. State a reason why the virus has spread to the Americas and likely to spread to Europe.
2. Define the term microcephaly.
3. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals.

Answers

Answer:

1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America  

2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.

3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies

Explanation:

The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.

Sugar plantations from Africa to the Caribbean and Louisiana and as far as Hawaii are haunted by stories of brutality, torture, r*pe, and murder. When slaves rebelled, they often took gruesome revenge on their masters, only to face even more horrific reprisals when the owners and overseers regained control. Indenture was a step better than slavery, but masters did their best to intimidate workers to keep wages low and silence critics. Violence was the very soil from which sugar sprang. The only way to fight sugar masters, it seemed, was for the workers to be harder, tougher, and more willing to accept bloodshed than the owners. Gandhi began to see that there was a way for the indentured Indians to strengthen themselves without having to rely on machetes and guns. Freedom, he realized, did not come only from rising up against oppressors or tyrants. It could also be found in oneself. The mere fact that the sugar masters treated their workers as some form of property did not mean the Indians had to accept that definition. In fact, it was up to them to claim, to assert, their own worth, their own value. A man who had his inner, personal dignity was freeno matter how a boss tried to bully him. Gandhis years in South Africa became a laboratory, as he experimented with how to be a truthful, free person. Finally, he was ready to put his ideas into practice.Which statement best describes the claim the authors make in this passage?A). Gandhi believed that violence should be used only as a last resort when fighting oppressors.B). Violent uprisings were common, but Gandhi worked to show that resistance could be nonviolent.C). Life for indentured workers was difficult, and sugar masters treated them like property.D). Workers' freedom depended upon the way that plantation owners treated workers.
