internal organs.
Answer:
Skeletal System
Explanation:
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
When he discovered that blood is pumped from the heart to the body, and back to the heart, ________ had a difficult time getting people to accept his discovery because it went against the ancient teachings of _______.
Answer:
1 - William Harvey
2 - Galen
Explanation:
Galen, who postulated that blood was produced continuously in the liver and absorbed by the body (not recirculated), served as the Roman emperor's personal physician. For 1500 years, his theories about human anatomy went unquestioned until Harvey's proposal in 1628.

What is the composition of blood ?blood is a fluid connective tissue contain blood cells and an plasma.
The major functions include transportation and providing immunity and protection.
The major components include plasma primary constituent of blood contain 55 percent of blood volume. It is made up of water, salts, proteins, and blood cells.
Red Blood Cells which determine blood type, biconcave in shape, enucleated contain millions of hemoglobin molecules.
White Blood Cells act as defensive cell in the immune system and lymphatic system against infection.
Platelets are formed from pieces of cells present in the bone marrow called megakaryocytes.

What word is used to describe plant cells placed in a hypotonic solution?
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

The invention of the microscope led to the discovery of the cell by Robert Hooke. While looking at cork, Hooke observed the box-shaped structures, which he called "cells" because they reminded him of the cells (rooms) found in monasteries. This discovery led to the development of the cell theory. Credit for developing the cell theory is usually given to two scientists. Theodor Schwann and Matthias Schleiden. The cell theory was then proposed by Theodor Schwann in 1839. There are three parts to this theory: living organisms are made up of cells, cells are the basic structural unit of all organisms, and all cells come from pre-existing cells. Which of these is supported by the tenets of the cell theory? Select ALL that apply. les )) A) Energy flow occurs within cells. B) Mitosis produces identical daughter cells. C) Living organisms can be unicellular or multicellular. D) DNA is copied and passed between cells during cell division. E) Single-celled bacteria grow and then divide in half to make new bacteria.
Living organisms are made up of cells, cells are the structural unit of all organisms, cells come from pre-existing cells Energy flow occurs within cells.
What are the main points of cell theory?The main points of cell theory are:
All living things are made up of cells.Cells are the raw building blocks of life.All cells come from preexisting cells through the cycle of cell division.Energy flow occurs within cells.Thus, cells come from pre-existing cells Energy flow occurs within cells.
