Answers
Answer: Palms and other small trees
Explanation:
Answer:
A. Palms and other small trees
Explanation:
Understory Layer
Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.

Which of the following are made mostly or entirely of proteins? (Select all that apply.)
fats
body tissues
carbohydrates
hormones
Answers
I think the answer is body tissue
Answer:
Body tissues/hormones
Explanation:
Excluding water and fat, the human body is made up almost entirely of protein. Protein is the main component of muscles, bones, organs, skin, and nails. Excluding water, muscles are composed of about 80% protein, making this nutrient especially important for athletes.
1) Protein hormones (or polypeptide hormones) are made of chains of amino acids. An example is ADH (antidiuretic hormone) which decreases blood pressure. 2) Steroid hormones are derived from lipids.
What is true for two pieces of iron at the same temperature that are different mass?
A) The average kinetic energy of their particles is different.
B) Heat flows from the larger object to the smaller object.
C) The total thermal energy of their particles is different.
D) Heat flows from the smaller object to the larger object.
Answers
Answer:
Their particles have the same total kinetic energy.
Explanation:
Their particles have the same total kinetic energy.
C) The total thermal energy of the particles in each piece of iron will be different, because the total energy of a substance is proportional to its mass. However, if they are at the same temperature, their average thermal energy per particle will be the same.

Answers
The correct statement about X-rays are:
X-rays have higher associated energy and can pass through skin and muscle tissue; option A and Radar waves have a wavelength that is larger and can detect more substantial objects without passing through them; option C.What are X-rays?X-rays are a type of electromagnetic radiation with high energy and short wavelength. They have the ability to penetrate materials and are commonly used in medical imaging to visualize bones and other internal structures of the body.
X-rays are produced by firing high-energy electrons at a metal target, which causes the release of X-ray photons. X-rays have both beneficial and harmful effects, and their use in medical imaging is carefully regulated to minimize the risks to patients.

Chiara knows that weight is affected by gravitational pull. She is putting together a poster to display in her classroom.
Since the moon's gravity is less than Earth's, all objects, including mammals, have different weights on the moon than on Earth. Use the table below to calculate how much a dog weighs on the moon.
Answers
Answer: A
Explanation: 150 lb * 1/6 = 25 lb
Chiara knows that weight is affected by gravitational pull. The weight of the dog on the moon is 25 lb. The correct option is A.
What is gravitational pull?Gravitational pull is the force of gravitation that pulls all the objects towards themselves. The force of gravitation is different on different planets, and on the moon, the gravitational pull of the moon is lesser than the earth.
The weight of the dog on the earth is 150 lb
The weight of any object on the moon is 1/6th of the weight of any object on the earth.
So to calculate the weight of the object on the moon, we should multiply the given weight of the dog on the moon by 1/6 to get the result.
150 lb x 1/6 = 25 lb
Thus, the weight of the dog on the moon is 25 lb. The correct option is A.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

a chemical change occurs when one or more substances change into entirely new substances with different properties
Answer:
Physical change is when change occur physically in a substance. It is usually reversible. It includes change in colour, shape, texture, volume etc.
Examples: Cutting of paper, making moulded stuff from dough etc.
Chemical change is when change occurs chemically in a substance. It is non-reversible. When ever a physical change happens, a new substance if formed.

a)Atomic number
B)Element symbol
C)Mass number
D)Atomic mass
Answers
Answer:
a)Atomic number
Explanation:
Element symbol signifies the element. For eg, Na is sodium. Mass number is the sum of protons and neutrons of an atom of an element. Atomic mass is the molar mass of the given element. Finally, atomic number is unique to each element because it signifies the number of protons of that element. EACH ELEMENT has their UNIQUE number of protons. For eg, atomic number of hydrogen is 1 because it has 1 proton, NO OTHER ELEMENT HAS ATOMIC NUMBER 1 because NO OTHER ELEMENT HAS 1 proton.

Answers
Answer : Minerals can form on the surface through evaporation of solutions containing dissolved minerals. Minerals can form beneath the surface when dissolved elements and compounds leave a hot water solution or when materials melted in magma/ lava then cools & hardens.
How does the arrangement of the atoms in a mineral relate to its properties?
The atoms in a mineral are arranged in an organised 'atomic structure'. They connect together to form molecules, and the molecules stack together in a regular pattern to form a crystal. The shape of a crystal depends on the way the molecules are stacked up inside it.
