2) Wind and Rain as well as erosion.

3) Gravity, Wind, Water.

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.

Asexual reproduction- one parent, unique, spores, uniform

Sexual reproduction- DNA, male and female, traits, egg, sperm

Reproduction is a type of biological process in which new organisms called offspring are produced  from parent or parents . In this process, organism make more organisms which look like themselves. It enables and ensure the continuity of species from generation after generation which is the main feature of life on Earth.

There are two types of reproduction.

1. Sexual reproduction

In sexual mode of reproduction, an organism combines a genetic information which is received from each of the parent. In this method, offspring which are produced from different from parents.

2. Asexual reproduction

In asexual reproduction,  a parent copies itself to form genetically identical offspring. In this method, offspring which are produced from identical to the parent.

Thus, Asexual reproduction- one parent, unique, spores, uniform

Sexual reproduction- DNA, male and female, traits, egg, sperm

Answer:

hello again! here ya go

Condensation

Explanation:

Condensation is the change of water from gas form to liquid form. When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets.

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.

Characteristics do organisms in kingdoms Plantae and Animalia have in common are they have eukaryotic cell and they are multicellular. Thus, option A and D are correct.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as reproduction digestion, breathing, and metabolism,  respiration.

In unicellular organism division of labour is at the organ level performed  on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.

Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore, characteristics do organisms in kingdoms Plantae and Animalia have in common are they have eukaryotic cell and they are multicellular. Thus, option A and D are correct.

It would be best to buy the bag of ice cubes because they come in a larger size. the larger the size of the object that should help cool it the faster it will cool it.

Your answer is Loess

Loess soils are among the most fertile in the world, principally because the abundance of silt particles ensures a good supply of plant-available water, good soil aeration, extensive penetration by plant roots, and easy cultivation and seedbed production.
