Answer:
The Circulatory System
A wall of muscle separates the hearth into two parts called chambers. Both chambers work at the same time and act like pumps. Each chamber has an upper part called the atrium ans a lower part called the ventricle. The right pump sends oxygen-poor blood and carbon dioxide-rich blood to the lungs.
In the lungs, the blood gets rid of the carbon dioxide and takes on a fresh supply of oxygen. The blood with carbon dioxide is bluish in color and the blood with oxygen is bright red.
The left pump receives the bright red blood from the lungs and send it to all parts of the body trough the main blood vessel called the aorta. This complete the pumping cycle.
Explanation:
The human heart has two main chambers, divided into two parts, responsible for the distribution of blood in the circuits known as major and minor circulation.
The major circulation involves the route that the blood, pumped by the heart, takes through the whole body, carrying the oxygen-rich blood —arterial with red blood— through the arteries, to then return as non-oxygenated or venous —bluish— blood through the veins, reaching the heart again. The minor circulation goes from the heart to the lungs and from these to the heart. The right ventricle sends the venous blood through the pulmonary arteries to the lungs, and returns through the pulmonary veins to the heart.A resume of the complete path of the blood in the body is :
The blood reaches the right atrium through the vena cava, enters the right ventricle and from there goes to the lungs, through the pulmonary arteries, the only arteries that carry venous blood.
The lungs send the blood to the left atrium, through the pulmonary veins —the only ones that carry arterial blood— it goes into the left ventricle and from there it is pumped to the whole body through the aorta artery, which distributes it throughout the arterial tree.

In the lab, Ann cools a closed container containing 50 grams of steam until all of the steam becomes a liquid. She then cools the container until the liquid water freezes. Which remains constant during all of these changes?
Answer:
The mass
Explanation:
The only thing that will remain constant during the change of state is the mass of the water molecules.
Steam consists of water molecules in a gaseous state. The mass remains constant as it is cooled from steam to liquid water in a closed container and then frozen to become ice, still within a closed system.
The cooling system is just exchanging energy with the surrounding without exchanging any matter. Hence, the mass of the water molecules remains the same throughout the change of state.
why do cells need to be small?
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small

The Grand Canyon is 446 km long, up to 29 km wide, and 1.6 km deep. The walls of the Grand Canyon are composed of nearly 40 different rock layers that represent about 1 billion years of Earth’s history. The rocks at the bottom of the canyon are metamorphic rocks formed 1.75 billion years ago. New sediments were deposited on top of those rocks, and mountain-building events around 755 million years ago tilted and lifted the new rocks. The total sandstone, shale, and limestone layers were deposited between 1,000 and 250 million years ago to form a rock sequence up to 1,525 m thick. WRITE YOUR ANSWER ON THE LINE.......IDENTIFY two geologic processes occurring in the Grand Canyon today that also contributed to the formation of the rocks that make up the Grand Canyon’s walls.
Answer:Geologists call the process of canyon formation downcutting. Downcutting occurs as a river carves out a canyon or valley, cutting down into the earth and eroding away rock.
Down cutting happens during flooding. When large amounts of water are moved through a river channel, large rocks and boulders are carried too. These rocks act like chisels, chipping off pieces of the riverbed as they bounce along.

What is Water cycle?In order to increase our capacity to forecast weather, climate, water resources, and ecosystem health, NOAA is working to deepen our understanding of the water cycle at all sizes, from the global to the local.
Life on Earth depends on water. Water connects the main components of the Earth's climate system, including air, clouds, the ocean, lakes, plants, snowfall, and glaciers, in its three states of solid, liquid, and gas.
The water cycle demonstrates how water is constantly moving both inside the Earth and in the atmosphere. It is a complicated system with a wide range of processes.
Therefore, Evaporation, condensation, and precipitation are frequently taught as three basic, circular processes that make up the water cycle.

The experimental variable is an important element that is defined by the metadata of each of the experiments. This is usually one or several attributes of the sample categories. The differing factors between the test and the control samples are defined by the experimental variables, which are being investigated.
The experimental variable can be either independent variables or dependent variables. The variables are often manipulated by the researchers in their studies for analysing the cause-and-effect relationship between both kinds of variables.
Following are the types of variables :
The cause is called the independent variable. The value of this variable will always be independent of the other variables in the study.The effect is the dependent variable. The value of this variable depends on the changes made in the independent variable.
