Answer:
B. A mouse that inherited a strong sense of smell from its parents
D. A mouse with black fur that was passed down through a gene
Explanation:
Answer:
B: A mouse that inherited a strong sense of smell from its parents
D: A mouse with black fur that passed down through a gene
Explanation:
In the article, it's stating that natural selection affects variations that are inherited, not acquired. Inherited means that that it's passed from parents to offspring through genetics. Acquired traits are "acquired" during an organism's life and develop.
Options B and D are correct because a strong sense of smell from its parents and genetically passed black fur are inherited traits. Only inherited traits can be affected by natural selection.

Q2 Different metals were discovered at different times throughout history. In general,
more reactive metals were discovered much more recently than less reactive metals.
Very unreactive metals, such as gold, were discovered in ancient times.
a) Suggest an explanation for the link between a metal's date of discovery
and its reactivity.
Answer:
The first metal known to be prepared from its ore was copper, perhaps as early as 6000BC6000BC in the Middle East. The ore, which contained copper(II) oxide, was heated with charcoal, which was prepared by the incomplete burning of wood, and is mainly elemental carbon. Later, iron and tin were prepared in the same way. Bronze, an alloy of copper and tin, was made by mixing copper-containing ore with tin ore and heating the mixture in the presence of charcoal.

What happens to most of the Energy that an organism gets from consuming food?
Help please
Answer:
When energy enters a trophic level, some of it is stored as biomass (as part of organisms' bodies). This is the energy that's available to the next trophic level, since only energy stored as biomass can get eaten.Explanation:

Describe the formation of ions by electron loss or gain
Explanation:
Ions form when atoms gain or lose electrons. This is so that they form a full outer shell of electrons. When an atom gains electrons it becomes a negative ion, because electrons are negatively charged. For example, all halogens (group 7 or 17) form negative ions as they gain an electron forming a 1- charge. When an atom loses electrons it becomes a positive ion, as it is losing some negative charge from the electrons. This would be for example, alkali metals (group 1) which lose an electron to form a positive ion with a 1+ charge, (ALL metals form positive ions).
During mitosis, this structure moves individual chromosomes?
Answer:
Anaphase
Explanation:
Two separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other.
what are 3 common chemical reactions of the carbon family?
1. form covalent compounds.
2. nonreactive.
3. ionic compounds.
The carbon family elements have widely variable physical and chemical properties. Overall, the carbon family elements are stable and tend to be fairly unreactive. The elements tend to form covalent compounds, though tin and lead also form ionic compounds.
Reaction of carbon with air
Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2. Diamond is a form of carbon and also burns in air when heated to 600-800°C - an expensive way to make carbon dioxide! ... This reaction is important. In industry, air is blown through hot coke.

An ioc occurs when what metric exceeds its normal bounds?.
An ionic bond is formed when there are more or less electrons that normal in bonding atoms.
What are Ionic bonds?An ionic bond is formed when one atoms donates electrons to another specie to form an ion pair. One atom is positively charged while the other specie is negatively charged.
Hence, an ionic bond is formed when there are more or less electrons that normal in bonding atoms.

How many moles in 67.8 g of F2 ( Fluorine compound)?
Answer:
1.78 moles
Explanation:
to find moles, use the formula moles=mass/rfm
the rfm is the mass number (the bigger number) on the element's square thingy on the periodic table
the mass number of fluorine is 19
19*2 (because it's diatomic you multiply it by 2) =38
so 67.8/38=1.78421052632
round it to 2 sf= 1.78 moles
ASAP!!! Explain: Why do black lines appear on the absorption spectrum of the sun?
The black lines in the Sun's spectrum are caused by gases on, or above, the Sun's surface that absorb some of the emitted light.
Jim needs to conduct his experiment at STP .Which condition must he use?
Answer:
273 K, 101.3 kPa
Explanation: I just did the quiz
To acquires STP condition, Jim must apply a temperature 298 K and 1 atm pressure. At STP condition one mole of all gases occupies a volume of 22.4 liters.
What is STP condition ?The standard temperature and pressure is called STP condition. A temperature of 298 K and pressure of 1 atm is called standard temperature and pressure.
At STP condition, the volume of one mole of any substance is 22.4 liters. One mole corresponds to 6.02 × 10²³ molecules. By satisfying the STP condition, we can determine the volume, and other mole parameters of a compound.
Experiments can be conducted at STP condition by applying a temperature of 298 K which is equal to 25°C and a pressure of 1 atm. He can use a thermometer and barometer to measure and set the values of temperature and pressure.

how many grams are in 3.45 moles of CO2?
Answer:
The weight of 3.45 moles of carbon dioxide has been 151.8 grams.
Moles can be calculated as the mass of solute present with respect to the molecular mass of the solute.
Moles can be expressed as:
Moles = \rm \dfrac{weight}{molecular\;weight}
molecularweight
weight
The molecular weight of carbon dioxide has been 44 grams/mol.
The given moles of carbon dioxide = 3.45 moles.
3.45 mol = \rm \dfrac{weight}{44\;g/mol}
44g/mol
weight
Weight of carbon dioxide = 3.45 \times× 44 grams
Weight of carbon dioxide = 151.8 grams.
The weight of 3.45 moles of carbon dioxide has been 151.8 grams.
