The statement that best describes the part of the atom that is shown by the arrow is it is an electron, and it has a negative charge. The correct option is A.
What is an atom?Particles inside atoms are referred to as subatomic particles. These can be found throughout the atom in various places. The particles are charged.
A neutron is neutral, a proton is positively charged, and an electron is a negatively charged particle that revolves around the nucleus. The nucleus contains neutrons and protons.
Valence electrons are the electrons that are present in the outer shell of the atoms. These electrons are free electrons to form bonds with the electrons of other atoms.
Therefore, the correct option is A. It is an electron, and it has a negative charge.

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.
Answers
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.

Which of the following associations is NOT correct?
A.
Fats - insulation
B.
Proteins - enzymes
C.
Carbohydrates - energy
D Nucleic acids - structural units
Answers
Answer:
D
Explanation:
Nucleotides are structural units of nucleic acids.
Nucleic acids are not associated with providing structural units. Option D is correct.
A. Fats - insulation: This association is correct. Fats serve as a source of insulation in the body, providing thermal protection and helping to maintain body temperature.
B. Proteins - enzymes: This association is also correct. Proteins are essential for the functioning of enzymes. Enzymes are protein molecules that act as catalysts in biological reactions, helping to speed up chemical reactions in the body.
C. Carbohydrates - energy: This association is correct as well. Carbohydrates are the primary source of energy for the body. When consumed, carbohydrates are broken down into glucose, which is used by cells as a fuel to carry out various functions.
D. Nucleic acids - structural units: This association is not correct. Nucleic acids, such as DNA and RNA, are not primarily involved in providing structural units. Instead, they play a crucial role in storing and transmitting genetic information, which is necessary for protein synthesis and the inheritance of traits.
In summary, option D is the correct answer because nucleic acids are not associated with providing structural units.

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.

The color of the ice cream is the independent variable in her experiments. So the correct option is A.
What is an experimental variable?
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.
Therefore the correct option is A.

Answers
Answer:
Someday, humans will run out of fossil fuels.
Explanation:
A factual statement is defined as the statements that are based on true facts and research.
A factual statement about natural resources is that "Someday, humans will run out of fossil fuels" because fossil fuels are non-renewable resources that take thousand or many years to form and are present in a limited amount in our environment. Many kinds of research are made on this topic which says that if fossil fuels will be used at the same speed by humans, someday humans will run out of fossil fuels.
Hence, the correct answer is " Someday, humans will run out of fossil fuels."

However, the main thing she needs to "change" in her methodology is to take samples from different lakes instead of taking samples from the same lake. This is because it is possible there are other factors affecting the population growth in that lake which might not be affected by the summer season.
