If an object leaves Earth's gravitational field and floats in space, which one of the following will change?
A. The object's mass.
B. The object's weight.
C. Neither the mass nor the weight of the object will change.
D. Both the object's mass and weight.
Answer: B. The object's weight
Explanation:
Weight depends on gravity and is a measure of how much force gravity exerts on an object. Mass is the measure of how much matter is in an object and doesn't depend on gravity. In space, mass doesn't change but weight does.

Energy efficiency = useful energy output/total energy input x 100(%)
If a power plant uses 100 units of energy to create electricity and the output is 5 units, where does the 95% of the energy input go?
A: Lost as heat
B: Lost as gas
C: Escapes the system as potential energy
Answer:
no
Explanation:
No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance

Tapeworms enter the human stomach through food. They feed on nutrients in the stomach and cause infections in the body. What does this association depict?
Answer:
Tapeworms are a parasite of humans
Explanation:
Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae. If you ingest certain tapeworm eggs, they can migrate outside your intestines and form larval cysts in body tissues and organs (invasive infection).

What are the three reasons why cells divide? What are the chromosome number in diploid and haploid cells? What are the phases of mitosis? What are the phases of the cell cycle?
Answer:
What Are the 3 Reasons Why Cells Divide?
•Repair of damaged tissue.•Growth of an organism.•Replace old and dying cells.What are the chromosome number in diploid and haploid cells?
•Humans have 46 chromosomes in each diploid cell. Among those, there are two séx-determining chromosomes, and 22 pairs of autosomal, or non-séx, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).What are the phases of mitosis?
•Mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.What are the phases of the cell cycle?
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.Explanation:

Electrons in an outer or
shell determine the chemical reactivity of atoms.
Answer:
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.
Explanation:
Electrons in an atom's outermost shell determine the chemical reactivity of atoms; this is true as the electrons in an atom's outermost shell, also known as its valence electrons, play a crucial role in determining the chemical reactivity of the atom.
What is an electron?The chemical reactivity of an atom depends on its ability to gain or lose electrons, which is determined by the number of valence electrons in its outermost shell. The valence electrons are the ones that are involved in chemical bonding, which is the process by which atoms combine to form molecules. Atoms with incomplete valence shells tend to be more reactive because they have a strong tendency to gain or lose electrons to achieve a stable configuration. A stable configuration is achieved when an atom's outermost shell is completely filled with electrons.
Hence, Electrons in an outer shell determine the chemical reactivity of atoms; this is true as the electrons in an atom's outermost shell, also known as its valence electrons,

What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.
