Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body.

Answer:

Tricuspid valve  is the path of blood through the heart and lungs

Explanation:

Blood is also responsible for transiting the blood and nutrients. The blood reached right atrium and from here it reached the right ventricles with the help of tricuspid valve. When the ventricles are full it closes to stop blood from going back to the atrium.

The inferior and the superior vena cava let the blood enter through them. The heart left the blood with the help of pulmonary valve to the pulmonary artery and the blood reached the lungs.

Give the definition of parasympathetic nervous system?
SashulF [63]

Answer: Autonomic nervous system is made up of 3 divisions; Sympathetic nervous system, parasympathetic nervous system and sympathetic division. All these divisions are involuntary actions where parasympathetic is ultimately responsible for the "rest and digest" part of it. When the body is at rest the parasympathetic nervous system inhibits or lowers high energy requiring bodily functions.

This nervous system will lower any fight or flight response actions such as the release of epinephrine into the blood and enable digestion, urination and defeacation. When engaged in digestion you feel relaxed and at rest, this is solely due to the parasympathetic nevous system.

The anemia resulting from a deficiency of either vitamin B 12 (cobalamin) or folate is caused by a disruption in DNA synthesis o
Vesnalui [34]

Answer:

The given statement is true.

Explanation:

A condition in which uncharacteristically large, unusual and immature RBCs known as megaloblasts gets generated by the bone marrow is known as megaloblastic anemia. The condition can arise due to many causes of which deficiencies of folate or vitamin B12 (cobalamin) are the most general ones. The mentioned vitamins perform an essential function in the generation of RBCs.  

The signs and symptoms of megaloblastic anemia are lightheadedness, shortness of breath, pale skin, unusual heartbeat, and dizziness. Some of the other signs of the condition are weakness in muscles, pains and aches, and dyspnea.

Why is it important for geologists to use both relative and absolute ages to determine the age of rocks?
uysha [10]

Answer:

to help and determine the exact age of the rocks

Explanation:

The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.

Scientist could age the rock using two methods. They are :

Relative ages

Absolute ages

Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.

The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.

The incidence of Down syndrome, also known as trisomy 21, increases with increasing maternal age. Which of the following errors
Naily [24]

Answer:. Nondisjunction during meiosis I in either the male and female gamete

The failure of   homologous chromosome to separate at mitosis,  or failure of sister chromatids  to separate at Anaphase of  meiosis I or ii is called  non-disjunction.

 In this  cell division anomaly the  unsegregated chromosomes  are  separated  into  cells as single chromosomes, therefore extra copies are  therefore inherited.This  result is one of the cell having an extra copies of  chromosomes than others( chromosomes 21.

If this extra  chromosome copies  is segregated into a sperm or egg, the resulting zygote cells will   have extra  copy as  chromosome 21, and hence Down syndrome.

→It is more common in Meiosis 1 than ii,because of longer duration of the first stage of division than meiosis ii,given rooms to errors.

→Most common in women(with age increase)  than men because of exchange of telomeres in   them,which  worsen with age. Their Meiotic mechanism  which   weaken with age, and  more prone to errors compare to men,
