Answer:
No, cardiac muscle tissue does not exhibit recruitment.
Explanation:
The cardiac muscle tissue does not recruit cells to contract. The reason is that the cardiac muscle contracts all its cells at once and with the same force. It does not have to recruit other cells since it does not have to lift objects of different weights. The heart's contraction aims to pump blood and to do it rhythmically. The heart has a natural peacemaker, the sinoatrial node. The Sinoatrial node transmits an electrical impulse to all the heart to contract it all at the same time and continuously. For these reasons, the cardiac muscle does not need recruitment.
Answer: a. During DNA replication, enzymes unwind DNA to provide a template for making identical DNA strands.
Explanation: The purpose of DNA replication is to produce genetically identical DNA molecules.
Replication is the process of copying a double-stranded DNA molecule into two identical daughter DNA. The enzyme known as helicase unwinds the DNA so that each strand will serve as a template for the synthesis of a complementary DNA strand. The. Two identical daughter DNA produced each contains one parent DNA strand and one new complementary strand.
Lipids are a group of organic compounds including fats, phospholipids, and steroids.
Lipids are a group of organic compounds that do not dissolve easily with water. Lipids include fats, oils, monoglycerides, diglycerides, triglycerides, phospholipids, hormones, vitamins (such as vitamins A, D, E, and K), and steroids. Lipids functions by storing energy for organisms, as chemical messengers between cells, tissues, and organs, and they also function as structural parts of cell membranes.
Answer:
From Thales, who is often considered the first Western philosopher, to the Stoics and Skeptics, ancient Greek philosophy opened the doors to a particular way of thinking that provided the roots for the Western intellectual tradition. Here, there is often an explicit preference for the life of reason and rational thought. We find proto-scientific explanations of the natural world in the Milesian thinkers, and we hear Democritus posit atoms—indivisible and invisible units—as the basic stuff of all matter. With Socrates comes a sustained inquiry into ethical matters—an orientation towards human living and the best life for human beings. With Plato comes one of the most creative and flexible ways of doing philosophy, which some have since attempted to imitate by writing philosophical dialogues covering topics still of interest today in ethics, political thought, metaphysics, and epistemology. Plato’s student, Aristotle, was one of the most prolific of ancient authors. He wrote treatises on each of these topics, as well as on the investigation of the natural world, including the composition of animals. The Hellenists—Epicurus, the Cynics, the Stoics, and the Skeptics—developed schools or movements devoted to distinct philosophical lifestyles, each with reason at its foundation.
With this preference for reason came a critique of traditional ways of living, believing, and thinking, which sometimes caused political trouble for the philosophers themselves. Xenophanes directly challenged the traditional anthropomorphic depiction of the gods, and Socrates was put to death for allegedly inventing new gods and not believing in the gods mandated by the city of Athens. After the fall of Alexander the Great, and because of Aristotle’s ties with Alexander and his court, Aristotle escaped the same fate as Socrates by fleeing Athens. Epicurus, like Xenophanes, claimed that the mass of people is impious, since the people conceive of the gods as little more than superhumans, even though human characteristics cannot appropriately be ascribed to the gods. In short, not only did ancient Greek philosophy pave the way for the Western intellectual tradition, including modern science, but it also shook cultural foundations in its own time.
