Does this model represent a compound? Explain your answer

Answers

Answer:

SAMPLE ANSWER:  The model does not represent a compound because it shows two atoms of the same element combined. To be a compound, the model would need to contain atoms of different elements, represented by different-colored balls.

why do the processes and events dating back to the big bang eventually led to the existence of life on earth​

Answers

Answer:

Stars are formed such that their death led to the creation of life.

Explanation:

The Big Bang theory was developed in 1927. This theory helps to understand how the universe was created. According to this theory, hydrogen gas was created through a process of expansion and explosion. As a result, stars are formed such that their death led to the creation of life.

Earth formed around 4.54 billion years ago which is equal to approximately one-third of the age of the universe.

Based on your knowledge of ocean chemistry, predict the feeding mode and size of organisms found in the deep layers of the ocean, and select the best explanation.

Answers

In the deep layers of the ocean, various distinct kinds of species are found like fangtooth fish and vampire squid, to sea urchins and coffinfish.  

One of the probable adaptation, which is not fully understood in the deep sea is gigantism. This refers to the ability of animals to become highly enormous in size. A well-known illustration is a giant squid, and others, like giant isopod, the kings of herrings selfish, and the colossal squid.  

One of the possible reason of gigantism is the tendency of the species in the deep sea to live for long years, that is, for decades or for even centuries. As food is not abundant in the deep zones, thus deep sea creatures have evolved some interesting mechanisms of feeding.  

In the non-existence of photosynthesis, the majority of food comprises of detritus, that is, the decaying leftovers of algae, microbes, animals, and plants from the upper layers of the ocean. Apart from that, the corpses of large animals, like whales that sink to the bottom give irregular but huge feasts for deep-sea animals.  


You have a mixture of three proteins X, Y, and Z.a. X is positively charged, has a mass of 100 kDa, it binds sugars.
b. Y is positively charged, has a mass of 200 kDa, it does not bind sugars.
c. Z is negatively charged, has a mass of 100 kDa, it does not bind sugars.

What will be the most efficient method to purify protein X from the mixture of X, Y, and Z?

i. washing
ii. drying
iii. ion-exchange chromatography
iv. gel filtration chromatography
v. affinity chromatography

Answers

Answer:

iii. ion-exchange chromatography

Explanation:

We have to purify the proteins and column chromatography is used widely for the purification of proteins. Ion-Exchange chromatography is also a type of column chromatography.

When the sugar binding protein X passes through the column, the sugar and  proteins binds together by exchanging ions and coagulated out no matter what the nature of charge on proteins...
