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.

Homologous chromosomes may exchange segments; this is called crossing over. crossing over increases genetic variability. when does crossing over occur?

Answers

A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.

Crossover happens while  chromosomes, usually  homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.

What are homologous chromosome?

Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.

Lifeforms have changed throughout Earth's geologic history. Scientists learn about these changes by studying the fossil record. For example, scientists have learned when different groups of organisms first appeared. These events can be placed within specific periods on the geologic time scale, which is shown below.


Fishes with jaws first appeared during the Silurian period, and dinosaurs first appeared during the Triassic period. Large mammals first appeared after both dinosaurs and fishes with jaws.

Using this information and the geologic time scale above, choose the period in which large mammals first appeared.

B.
Ordovician
C.
Tertiary
D.
Cambrian

Answers

Answer:

C. Tertiary

Explanation:

Tertiary is the period in which large mammals first appeared.

What is Tertiary period?

The Cenozoic era's initial geological phase is the tertiary, which is also known as the Paleogene and Neogene periods. Between 66 million and 2.6 million years ago, there was a geological epoch called the Tertiary.

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.

Therefore, Tertiary is the period in which large mammals first appeared.

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.
