<span>Prokaryotes: 1. bacteria grows in competitive rapid conditions 2. simple needs, and single celled 3. don't have cell specific gene expression 4. have to respond quickly to changes in their environment 5. organized in operons and transcribed by a single mRNA 6. polycistronic mRNA 7. transcription and translation can occur at the same time Eukaryotes: 1. have other regulatory needs so they have a different set of regulatory controls 2. are NOT regulated by operons 3. each structural gene has its own promoter and is transcribed independently 4. monocistronic 5. chromatin structure affects gene expression 6. transcription requires unwinding of the DNA form the histone proteins 7. eukaryotic cells have many more transcriptional activators as well as gene repressors (DNA binding proteins) 8. transcription and translation are physically separated so the regulatory mechanisms must differ from those in bacteria</span>

Ivanshal [37]

Answer:

Cell level organization

Explanation:

Organisms are composed of different level of organizations like atomic level, molecular level, cell level, tissue level, organ  level, system level after which whole organism if formed.

If we talk about <u>Arachnoidiscus</u> <u>ehrenbergi </u> it is one celled organism belonging to a group of algae. If we talk about human stomach it is an organ made up of several tissues which in-turn are made up of several cells.

So what is common in both?

It is a cell that is common in both, because cell is the basic unit for life of <u>Arachnoidiscus</u> <u>ehrenbergi </u>and a unit of the composition of whole stomach.


Hope it help!

A brown cow is mated with white cow and they produce a roan cow Roan cows are brown with white spotsWhich statement best explain
jek_recluse [69]
C.
In co-dominance both traits show up, and in incomplete dominance the two traits mix together.

So automatically A, B and D are wrong, since we can see both brown and white colors on the cow separately.

If it were any of those we wouldn't be able to see any of the traits alone they would be a mix.

Answer:

Because salt is soluble in water, salt applied to such surfaces dissolves. Liquid water has what is known as a high dielectric constant, which allows the ions in the salt (positively charged sodium and negatively charged chlorine) to separate.
