What is the percent by mass of 8.0g copper is added yo enough zinc to produce 100g an alloy brainly
kogti [31]

Answer:

8%

Explanation:

Given that,

Mass of solute = 8 g

Mass of soultion, (mass of alloy) = 100 g

We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :

\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%

So, the percent by mass is 8%.

Which of the following claims about the TYR, TRP2, and TRP1 mammalian genes is most likely to be accurate?
Illusion [34]

The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon is most likely to be accurate.

The option a is correct.

Explanation:

The genes for the Tyrosinase, TRP2 and TRP1 are located on the same chromosome and are operons. These are operons because they are controlled by same transcription factors on mRNA.

Tyrosinase enzyme is important for the synthesis of melanin, eye pigments and hair colour. The synthesis of all these is completed in three distinct reactions  catalysed by TRP1, TRP2 and Tyr genes. These work as operon and the protein product is almost 40% similar of the three genes.

The amount of melanin production depends on tyrosinase enzyme activity of all the three genes.

The genetic regulation is done by operons.

A scientist is using relative dating to determine the age of a fossil that she discovered.
Dmitry [639]

Answer: D.finding fossils in the same area that are in layers closer to the surface.

Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.  

The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion.

Two similarities between the way<br> that a fungus feeds, and the way that<br> you feed.
Alexandra [31]

Answer:

Humans and fungi have a few similarities and a few differences.

Human's and fungi have similar feeding habits.

1- They are both heterotrophic (unlike plants, algae, etc. )

This refers to the fact of generating energy by consuming elements in the ecosystems.

This means that both get energy by feeding on other organisms.

2-Humans and fungi both cannot produce their own food using photosynthesis. They are not like plants.
