3.Explain why you need fiber in your diet even though you can’t digest it.
4.Why is water considered a nutrient?
Answers
Answer:
1. It provides not a lot of energy due to its lack of protein
2. Macronutrients are big picture nutrition categories, such as carbohydrates, fats, and proteins. Micronutrients are smaller nutritional categories, such as individual vitamins and minerals like calcium, zinc, and vitamin B-6.
3. Fibers keep your digestive system clean and healthy, easing bowel movements, and flushing cholesterol and harmful carcinogens out of the body.

1. As the ice melts into liquid water, what happens to the kinetic energy of the particles in the sample?
2. How does the kinetic energy of the particles in the sample relate to the sample’s temperature?
Answers
Answer:
#1 the particles gain kinetic energy they become 'excited' and they break the bonds that hold them together as a solid.

Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler substance through direct contact.
Which feature forms as a result of conduction between magma and water?
di ke
hot spring
caldera
batholith
Answers
Answer:
hot spring
Explanation:
im not entirely sure tbh
Hot springs are formed as a results of conduction of heat between the magma and water. Thus, the correct option is B.
What is Heat conduction?
Heat conduction is the transfer of the internal thermal energy of a system by the collisions of microscopic particles and movement of electrons within a body. The microscopic particles of the body in this heat conduction can be molecules, atoms, and even electrons. Internal energy includes the kinematic and potential energy of the microscopic particles of an object.
Hot springs are formed when the rainwater or the groundwater heats upon by coming in contact with the rocks which have been heated up by the magma, deep beneath the Earth's surface, Hot Spring is formed. This form of geothermal spring generally occurs in the areas near volcanic activities on the planet.
Therefore, the correct option is B.

Why is growth and reproduction of a cell cycle?
Answers
Answer:
In addition, a larger cell is less efficient in moving nutrients and waste materials across the cell membrane. - Asexual reproduction is the production of genetically identical offspring from a single parent. During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells.

Water is a polar molecule. On one side there is a positive electrical charge. On the other side there is a negative charge. Water is the only substance on Earth that is stable in all three states. Earth is the only planet in the solar system that has water in all three states.
How has water allowed life to become so diverse and complex on Earth? Cite evidence from the text that best supports this idea.
Answers
Answer:On Earth, water is the solvent critical to life without which organisms cannot survive. Its presence is so critical, because water provides an environment allowing some chemical bonds to be stable and to maintain macromolecular structure, while at the same time assisting in the dissociation of other chemical bonds

how do fossils give evidence of continental drift? List 2 examples using fossils found on different land masses.
Answers
Answer:
Explanation:
There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be:
The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.
They swam to the other continent/s in breeding pairs to establish a second population.
you discover that an atom of an unknown element had 54 protons. identify the element and explain how you know the identity is correct. explain whether the unknown element is more or less reactive than an atom of an element that has 30 protons. identify an element that would have very similar chemical properties (as element 54) to the unknown element and explain why its chemical properties would be similar.
Answers
Answer: Xenon
Explanation:
if you look on the periodic table of elements, youll notice that the only element with 54 protons is Xenon. Hope this helps!!
Protons are the positive charged subatomic particle that lies with the neutron in the nucleus of the atom.
The unknown element with 54 protons will be Xenon.
It is because Xenon is the only element in the periodic table having 54 protons. Element has the same number of protons and electrons therefore Xenon is the element that will have 54 protons.
It belongs to the noble gas group because the outer shell is a filled valence shell that is stable and less reactive compared to other elements.
Therefore it will be less reactive compared to the element having 30 protons.
The elements having similar properties as Xenon will be helium, neon, argon etc because they have the same group in the periodic table.

A a hormone
B an enzyme
C an oil
D water
Which group of compounds ensures that metabolic reactions take place effectively?
A carbohydrates
B enzymes
C fatty acids
D hormones
Answers
Answer:
Question 1 :
Ans - C
Explain - Binomial system is made up of Genus (Capital letter) and species (small letter).
# order needs to be correct, Genus
species
Question 2 :
Ans - B
Explain - Meat contain protein where enzymes break down protein into amino acids.
Question 3 :
Ans - B
Explain - Enzyme is a biological catalyst where they speed up chemical reaction.
1. The correct way of naming an organism using the binomial system is Ranunculus acris.
2. When an enzyme is added to meat, amino acids are produced.
3. Enzymes ensures that metabolic reactions take place effectively.
What is binomial system?"Binomial system/nomenclature is the biological system of naming the organisms in which the name is composed of two terms, where, the first term indicates the genus and the second term indicates the species of the organism."The first letter of genus should be in capitals.The species name should be in small letters.What is an enzyme?Enzymes are biological catalyst that increases the rate of metabolic reactions.What are amino acids?"Amino acids are molecules that combine to form proteins."Meat is abundant in protein and when protein digestive enzymes are added it breaks down into its simpler form i.e., amino acids.
Hence the correct answers are: 1. C. Ranunculus acris, 2. B. an enzyme and 3. B. enzymes.
