Answer:
Different mass
Different volume
Same density
Explanation:
Intensive physical properties are those properties of a substance that is not dependent on amount i.e. do not change in response to changes in the amount of the substance. Intensive properties include density, temperature, boiling point etc.
On the other hand, extensive properties are those properties that are dependent on the amount of the substance. For example, mass and volume are extensive properties.
Hence, according to this question, measuring an entire bar of soap and comparing it to a piece of soap, the bar and the piece would have a:
- Different mass ( size dependent)
- Different volume (size dependent)
- Same density (size independent)
According to the periodic table, which of the following is the most accurate model of an atom of boron?
Answer: boron has 5 protons and 6 neutrons
Explanation:
According to the periodic table, the model of an atom that describes an atom of boron is model A. Boron has 6 neutrons and 5 protons.
What is a periodic table?
The chemical elements are arranged in rows and columns in the periodic table, also called the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences, and is frequently regarded as a symbol of chemistry.
The atomic number is the number of protons, which is characteristic of a chemical element. The atomic number increases from left to right in the Periodic table.
Boron is an element with atomic number 5, which means it has 5 protons and 5 electrons, boron atom has a neutral charge.
The electron configuration of boron: ₅B: 1s² 2s² 2p¹, it has three valence electrons in 2s and 2p orbitals.
Therefore, the correct option is A, model A. Boron has 6 neutrons and 5 protons.

________ proteins or channel proteins are used to aid substances across the cell membrane in passive transport
Answer: channel proteins
Explanation:
Water channel proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane. A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane.
Explain the process of nuclear fusion. How many hydrogen atoms combine to form a single helium atom?
Answer:
The Hydrogen Fusion Process In the basic Hydrogen fusion cycle, four Hydrogen nuclei (protons) come together to make a Helium nucleus. This is the simple version of the story. There are actually electrons, neutrinos and photons involved that make the fusion of Hydrogen into Helium possible.
Explanation:
Answer:
This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy

Which statements describe the breakdown of lipids?
-The enzyme is a catalyst
-The name of the enzyme is lipase
-The enzyme speeds up the reaction
-The enzyme is made of RNA molecules
-The enzymes is degraded in the reaction
-The enzyme is involved in an anabolic reaction
Answer:
I think the second one
The name of the enzyme is lipase
Explanation:
because enzyme is a catalyst not because of breakdown of lipids but because it speeds up the biochemical reaction
this is a fact that enzyme speeds up the reaction.it is not because of lipids
enzymes is not degraded in the reaction.
anabolic reactions are the reactions that synthesizes larger molecules to smaller ones, not related to breakdown of lipids.
enzymes is not made up of RNA molecules. They are made up of proteins

Explanation:
Explain the relationship between the number of daylight hours and seasons.
Explanation:
The tilt of the Earth's axis also defines the length of daylight. Daylight hours are shortest in each hemisphere's winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights.

A. high mutation rate; antibiotic
B. high mutation rate; vaccine
C. low mutation rate; antibiotic
D. low mutation rate; vaccine
Answer:
B. high mutation rate; vaccine
Explanation:
The enormous genetic diversity of HIV is largely the result of its high mutation rate, and it has made it especially difficult to create a vaccine against the virus.
This ultimately implies that, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.
Hence, the human immunodeficiency virus (HIV) possesses a high error rate

Which evolutionary mechanism increases inheritable variations
Answer: Natural Selection. Natural Selection leads to an evolutionary change when some individuals with certain traits in a population have a higher survival and reproductive rate than others and pass on these inheritable genetic features to their offspring.
Explanation:
Dogs and wolves are more closely related to each other than either is to cats.
Explain how you would separate these organisms into clades.
Answer:
I would split these organisms into two paraphyletic groups: 1-one group composed of wolfs and dogs, and 2-one group including all three species (dogs, wolves and cats).
Explanation:
A clade is by definition a monophyletic group, it means that a clade is a group composed of a common ancestor and all its lineal descendants. Moreover, a paraphyletic taxon is a group of organisms that share a most recent common ancestor and some of its descendants. In this case, wolves and dogs can be grouped to form a more inclusive group since both species belong to the same genus (Cani), while dogs, wolves and cats can be grouped to form a major group because these three species are mammal species. In consequence, in this case, we have two paraphyletic groups supported by synapomorphic (shared, derived) characters, since wolfs and dogs represent only two species within genus Canis, while dogs, wolves and cats represent three species within class Mammalia.

ill give you a brainliest if it is right
Answer:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
magma-hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
igneous rocks- Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

So yellow is mostly the classification of Metal, But I don't see that option here. Answer-Blue
Blue color of the periodic table image represent transition metal. Thus, option A is correct.
What are transition metal ?The metal which have valence electrons that can participate in the formation of chemical bonds called as transition metal.
In a periodic table the position of transition metal is the long middle portions of the periodic table and form Groups 3 elements through 12.
These are paramagnetic metals, a good conductors of heat and electricity, in a solution their compounds are brightly colored when hydrated.
Every transition metal has multiple positive oxidation states, hard solid with high melting points and boiling points.
The elements are dense, less reactive but are good catalysts which form complexes with molecules called ligands.
Transition metal ions have incomplete filled d-orbitals, except for scandium
Some of the transition metals are iron, chromium, vanadium, titanium, cobalt, nickel, tungsten, gold, and platinum.
Thus option A is correct.
