Answers
Answer:
1. Because only regular-shaped objects have a consistent length, width, height, and shape. When dealing with an object composed of differing shapes, you must calculate each portion separately and then add them. For instance, if you have a swimming pool of two depths and want to determine cubic feet, you would have to calculate the volume for each section and then add them.
2. method used to figure the volume of an irregular shaped object Neither measurement is more "accurate" than the other--they simply denote different things. Length is a measurement of the distance between two points in space. The area is a measurement of the surface covered by a given shape.

Blood passes from the right ventricle to the _____ and then the _____ before reaching the lungs to pick up oxygen. Multiple choice question.
Answers
Blood passes from the right ventricle to the Pulmonary valve and then the Pulmonary artery before reaching the lungs to pick up oxygen
Blood circulation procedureWhen the blood enters the right ventricle it contracts and sends the blood through the Pulmonary valve before it reaches the Pulmonary artery which is passes the blood to the Lungs where it becomes oxygenated.
Hence we can conclude that Blood passes from the right ventricle to the Pulmonary valve and then the Pulmonary artery before reaching the lungs to pick up oxygen.

7. Discuss the practical and theoretical differences between an interval training program used to improve the ATP-PC system and a program designed to improve the ATP production via glycolysis.
Answers
The ATP-phosphocreatine (PC) system is more suitable in conditions of high energy expenditure, whereas glycolysis is a step during cellular respiration.
What is cellular respiration?Cellular respiration is a chemical process by which aerobic cells generate energy in the form of ATP by using foods as a source of energy in presence of oxygen.
During cellular respiration, glycolysis (glycolytic pathway) is the first step for ATP production.
The ATP-PC system is anaerobic, works in hypoxia conditions (oxygen absence), and is faster to provide energy than cellular respiration.
However, the ATP-PC system is energetically less efficient than cellular respiration in terms of the number of ATP molecules produced per unit of glucose.

Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece.

The Cretaceous-Paleogene extinction catastrophe at the beginning of the Cenozoic Era marked the start of the Tertiary Geological Period, which lasted until the Quaternary Glaciation at the end of the Pliocene Epoch.
The tertiary period began approximately 66 million years ago with the extinction of the dinosaurs, and it ended when the Quaternary Period's ice ages started, or roughly 2.6 million years ago.

Neurons in which dendritic and axonal processes are continuous and the soma lies off to one side are called.
Answers
The neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.
What is a unipolar neuron?The neuron is the structural and functional unit of the nervous system, which when they have only a short projection that later branches into two or more branches, are considered unipolar.
That is, they are those neurons in which only one extension or neurite emerges from the soma, which will act as an axon and at the same time will have dendrites with which it can both receive and transmit information.
Therefore, we can conclude that the neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.

When genes are close together on the same chromosome called as linked genes, means the alleles present together on one chromosome and it will be inherited as a unit.
What is chromosome ?A chromosome is located in nucleus of the cell is the main carrier of genes or DNA; It is a thread-like structure observed in plant, animal and human cells and composed of molecule of DNA (Deoxyribonucleic acid) and histone proteins.
DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and RNA content ranges from 1 to 10% in chromosome.
There are Two types of protein present such as histone and non-histones proteins where histone protein constitute portion (90% of total protein), whereas non-histone protein occupy a small portion (around 10% of total protein).
The histone protein is basic in nature, whereas, the DNA is acidic, so neutralization occur, DNA in chromosome can be present as forms such as Euchromatin and Heterochromatin.
