Answer 1

Answer:

B. All carbon atoms have six protons and six electrons.

D. Atoms of some naturally occurring carbon isotopes may have six neutrons

Explanation:

Isotopes are atoms of the same elements having same atomic number but different atomic masses.

Atomic number is the number of protons (or electron number in neutral atoms) present in the atomic nucleus of the atom.

Atomic mass number is the sum of protons and neutrons present in the nucleus of the atom.

Considering the options above from the above definitions:

A. All carbon atoms have six neutrons is false because carbon-12, carbon-13 and carbon-14 has 6, 7 and 8 neutrons respectively.

B. All carbon atoms have six protons and six electrons is true because the atomic number of carbon is 12.

C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons is false because atoms of all carbon isotopes have six electrons.

D. Atoms of some naturally occurring carbon isotopes may have six neutrons is true because atoms of carbon-12 have six neutrons.

E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons is false because none of carbon-12, carbon-13 or carbon-14 have twelve neutrons.

How do you know that energy and matter are conserved during the process of cellular respiration?

Answers

Answer:

Energy and matter are conserved in cellular respiration because it has identifiable inputs and outputs. These can be modeled with chemical equations.

Food undergoes chemical reactions in organisms to generate new molecules for growth or energy. Therefore, energy and atoms are conserved during cellular respiration.

What is conservation of energy and matter in cellular respiration?

The law of conservation of energy states that energy cannot be created or destroyed but can be changed from one form to another. The law of conservation of matter states that the total mass within a closed system that does not allow matter or energy to escape should remain constant. However, the law of conservation of energy states that energy can change from one form to another.

The process of cellular respiration is an example of a chemical reaction, which involves the transformation of one type of matter into another. A chemical equation describes this change in molecular structure. This is the cellular respiration chemical equation:

[tex]C_{6} H_{12} O_{6} + 6 O_{2} = > 6CO_{2} + 6H{2}0 + energy[/tex]

(Glucose + Oxygen yields Carbon Dioxide + Water + Energy)

Therefore, the amount of carbon dioxide atoms released by respiration is the same as the amount of  atoms in the oxygen and carbon that were changed.

How are the functions of a cell similar to the functions of an organ system?

Answers

Answer:

Organelles in a cell are essentially the same as organs in an organism. The mitochondria is the powerhouse of the cell, as we all know. It creates ATP, which is what gives the cell energy. This is similar to how we consume food and create energy from it. Cell membranes are similar to skin, as they keep needed things in, and unwanted things out. Our cells need water too, as it helps create the cytoplasm. We need water to keep us alive and well, as it helps to create many of our needed bodily fluids, and rid us of toxins.

Aerobic respiration involves the reaction of oxidation which involves the acceptance of electrons when the molecular oxygen reacts with protons to form water molecules. Thus, the correct option is A.

What is Aerobic respiration?

Aerobic respiration is the chemical process in which molecular oxygen is used to make the energy in the form of ATP from carbohydrates. It is also called as aerobic metabolism, and oxidative metabolism.

Aerobic organisms can use molecular oxygen (O₂) to generate energy in the form of adenine triphosphate (ATP). The role of molecular oxygen in the process of cellular respiration is to act as the end acceptor of electron. As the electrons are dropped off at the inner mitochondrial membrane during the process of cellular respiration, they travel through the electron transport chain and  are finally accepted by the molecular oxygen to form water.

Therefore, the correct option is A.

Rosa could be looking at plant cells.

Plant cells are generally joined together when tissues of plants are viewed under the microscope and each cell is usually with a cell wall. Animal cells, on the other hand, do not have cell walls.

Tissues are generally composed of similar cells that have been aggregated together to perform a function in the body of organisms. Both plant and animal tissues consist of many cells but only plant cells have cell walls.

How does the muscular system help humans maintain posture?

2.Muscles continually push bones to be straight.
3.Muscles constantly contract to help fight gravity.
4.Muscles constantly contract to help work with gravity.

Answers

Answer:

a

Explanation:

Muscles continually align themselves vertically to help maintain posture.

What is Muscular system?

Muscle fibers are specialized cells that make up the muscular system. Their ability to contract is its main characteristic. Movement is caused by muscles that are connected to blood vessels, internal organs, or bones.

Muscle contraction is the primary cause of almost all bodily movement. Cilia, the flagellum on sperm cells, and certain white blood cell amoeboid movement are examples of exceptions to this rule.

Walking and running are two examples of visible movements that are produced by the coordinated action of joints, bones, and skeletal muscles. Skeletal muscles can also make softer motions that influence different facial expressions, eye movements, and breathing.

Therefore, Muscles continually align themselves vertically to help maintain posture.

Which of these characteristics is NOT a property of water? (SC.912.L.18.12) A. Increases density as it solidifies B. Functions as a universal solvent C. Exhibits a highly cohesive behavior D. Moderates changes in temperature

Answers

Answer:

Option A.

Increases density as it solidifies

Explanation:

Increases density as it solidifies is not the characteristics of water because when water solidifies or freeze it become less dense or lighter compare to liquid water. When water solidifies to ice, it molecules are packed together and it is arranged in six sided crystalline shape which make it to be less dense or lighter than the liquid water molecules which is denser or more heavier.

Explanation:

Trace evidence is like fiber or hair or gunshot residue to it would be B. Trace evidence

The physical evidence and trace evidence are both reviewed under microscopy. Therefore, option A and option B are correct statements.

What is microscopy?

Microscopy is a technique to review the smaller size object at high magnification. Forensic science uses the physical or trace evidence found at the crime scene to review under microscopy.

Physical evidence refers to the tangible objects found at the crime scene, such as murder weapons or tool marks. On the other hand, trace evidence refers to the small or even microscopic pieces of evidence left at the crime scene, such as hair, or DNA.

Using the microscopy technique, the forensic team can determine the source of the murder weapon used at the crime scene or even link the suspect to the death of the victim. However, other types of evidence that do not come under microscopy, such as testimonial evidence or circumstantial evidence are also used to build a strong case against the suspect.

Therefore, the physical evidence and the trace evidence both are reviewed under microscopy.
