When pulled slightly, the atom moves in response to attractive forces.
Meaning of potential energy curve::
It is common to find the potential energy curve that explains the bonding of two atoms to form a molecule. There is minimum intermolecular interaction when the atoms are isolated from each other.
Attractive forces:When the atom is pulled away only slightly, so that it is still within the attraction curve on the graph, it moves in response to attractive forces.

White Blood Cell are part of the immune system. White Blood Cell helps the body to defend itself against pathogens.
Describe how pathogens cause infections and describe how the immune system defends the body against these pathogens.
Answer:Your blood is made up of red blood cells, white blood cells, platelets, and plasma.
Your white blood cells account for only about 1% of your blood, but their impact is big. White blood cells are also called leukocytes. They protect you against illness and disease.
Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.
White blood cells are made in the bone marrow. They are stored in your blood and lymph tissues. Because some white blood cells have a short life of 1 to 3 days, your bone marrow is always making them.
Types of white blood cells
Among your white blood cells are:
Monocytes. They have a longer lifespan than many white blood cells and help to break down bacteria.
Lymphocytes. They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders.
Neutrophils. They kill and digest bacteria and fungi. They are the most numerous type of white blood cell and your first line of defense when infection strikes.
Basophils. These small cells seem to sound an alarm when infectious agents invade your blood. They secrete chemicals such as histamine, a marker of allergic disease, that help control the body's immune response.
Eosinophils. They attack and kill parasites and cancer cells, and help with allergic responses.
Problems affecting white blood cells
Your white blood cell count can be low for a number of reasons. This includes when something is destroying the cells more quickly than the body can replenish them. Or when the bone marrow stops making enough white blood cells to keep you healthy. When your white blood cell count is low, you are at great risk for any illness or infection, which can spiral into a serious health threat.
Your healthcare provider can do a blood test to see whether your white blood cell count is normal. If your count is too low or too high, you may have a white blood cell disorder.
A number of diseases and conditions may affect white blood cell levels:
Weak immune system. This is often caused by illnesses such as HIV/AIDS or by cancer treatment. Cancer treatments such as chemotherapy or radiation therapy can destroy white blood cells and leave you at risk for infection.
Infection. A higher-than-normal white blood cell count usually means you have some type of infection. White blood cells are multiplying to destroy the bacteria or virus.
Myelodysplastic syndrome. This condition causes abnormal production of blood cells. This includes white blood cells in the bone marrow.
Cancer of the blood. Cancers including leukemia and lymphoma can cause uncontrolled growth of an abnormal type of blood cell in the bone marrow. This results in a greatly increased risk for infection or serious bleeding.
Myeloproliferative disorder. This disorder refers to various conditions that trigger the excessive production of immature blood cells. This can result in an unhealthy balance of all types of blood cells in the bone marrow and too many or too few white blood cells in the blood.
Medicines. Some medicines can raise or lower the body's white blood cell count.
Conditions such as extreme physical stress caused by an injury or emotional stress can also trigger high white blood cell levels. So can inflammation, labor or the end of pregnancy, smoking, or even extreme exercise.

What happens when the barrel goes over the waterfall?
WILL GIVE BRAINIEST!!!
Answer:
The barrel will crash down after falling over a waterfall.
Explanation:
The force of the barrel and the gravity that brings down the barrel will make the barrel fall at a high speed, and when it hits the water, it will go through to the bottom and break apart into pieces.
#teamtrees #WAP (Water And Plant)
The barrel crushes when it goes over the waterfall due to it's own weight and the force of gravity.
What is gravity ?The force that pulls items toward the center of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity.
Gravity is highly significant—it gives us weight, keeps us naturally on the ground, requires lift from airplanes to push them into the air, and even keeps objects like planets in orbit.
There are just two factors that matter when discussing the gravitational pull of one item on another: the mass of each object and the distance between them. The magnitude of the gravitational pull between two objects is proportional to the product of their respective masses and the square of the distance that separates them.
Therefore, when a barrel goes over the waterfall, the speed at which it is falling increases and it crashes.

Why do all swordfish have ‘swords’? Use the word ‘inherited’ in your answer.
The swordfish bill, on the other hand, is smooth and horizontally flattened, better suited perhaps for whacking larger prey like squid. Beyond their "swords," all billfish come equipped with a remarkable internal heating system for their eyes, keeping them ten to fifteen degrees Celsius warmer than ambient water temperatures.
sorry if it didn't help but pls brainliest? :/
All swordfish have 'swords' because it is a characteristic inherited trait from their parents.
Inherited traits are passed down from one generation to the next generation through genes. In the case of swordfish, the sword-like bill which is present is a unique adaptation that has been passed down through generations. This bill is believed to have evolved to help the swordfish in catching prey, defending themselves, and also in attracting mates.
The swordfish that had longer bills were more successful in survival and reproduction, which is the reason why this trait has been preserved and is observed in all swordfish today.The traits that are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance is determined by certain rules of heredity.
Thus, all swordfish have sword as they are inherited traits.

How is the nitrogen cycle important to humans?
It produces free nitrogen that humans can breathe.
It converts nitrogen into a form that humans can obtain by eating other organisms.
It produces nitrogen compounds that humans can breathe.
It converts nitrogen into a form that humans can obtain by absorbing it through their skin.
The nitrogen cycle is important to humans because it converts nitrogen into a form that humans can obtain by eating other organisms.
The statement "It converts nitrogen into a form that humans can obtain by eating other organisms" is the one that best describes the importance of the nitrogen cycle.
What is the nitrogen cycle?It is the biogeochemical circuit that supplies nitrogen to living things and keeps it circulating in the biosphere.
Importance of the nitrogen cycleThe nitrogen that is part of the atmosphere in the form of N2 cannot be used by animals and plants, and for this reason, this mechanism is needed to convert the N2 into usable forms.Following the order of the food chain, the nitrogen in the plants passes to the herbivorous animals and then to the carnivores, spreading between the different links of the food pyramid.Humans use nitrogen to make amino acids, proteins, nucleic acids, and DNA.Therefore, we can conclude that the nitrogen cycle is a vital circuit for the existence of animals, plants and human beings, since we are unable to fix nitrogen from its gaseous form.

Answer:
A Chemical, gas produced
Explanation:
Answer:
[tex]\boxed {\boxed {\sf A. \ Chemical \ change-gas \ produced}}[/tex]
Explanation:
Baking soda (NaHCO₃) and acetic acid (C₂H₄O₂) in vinegar react.
They form water (H₂O), sodium acetate (NaC₂H₃O₂), and carbon dioxide (CO₂).
This must be a chemical change, because new products are formed. We can eliminate choices B and C, because they are physical changes. Physical changes don't require a chemical composition change.
So, we are left with choices A and D.
Choice D must be incorrect because mass cannot disappear. According to the Law of Conservation of Mass, mass can't be made or destroyed.
That leaves choice A. Combining baking soda and vinegar is a chemical change, because new products, like gas, are formed. The gas helps blow up the balloon.
