In the information flow from dna to protein, what are the functions of transcription and translation
Brrunno [24]
Transcription is the first step, where a complementary strand of RNA is made,w which is modelled off the DNA.

This RNA called mRNA (messenger RNA) moves out of the nucleus to the ribosomes (sites of protein manufacture) where translation occurs. Translation is where amino acids are made to string together based off the code in the mRNA

Devise an experiment that tests the effects of changing salt concentrations on regeneration of brain cells in Alzheimer’s patien
Makovka662 [10]

Experiment that tests the effects of changing salt concentrations on regeneration of brain cells in Alzheimer’s patients.

Explanation:

Experiments are conducted on brain cells by first growing human embryonic stem cells in a Petri dish and then converting them to brain cells. later the Alzheimer’s disease was genetically engineered into those nerve cells through gene mutation.

When these cells are exposed to varying concentrations of salt solution, the cells with shrink or swell according to the concentration due to cellular osmosis.

The cells will undergo chemical changes due to this. The regeneration probabilities of nerve cells affected by Alzheimer’s disease can be studied by such experiments.

How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of bot
nataly862011 [7]

Answer:

Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH.

Explanation:

A Calvin Cycle is defined as a process by which various plants and algae takes carbon dioxide from the air and turns it into sugar, the food which the  food autotrophs needs to grow. The Calvin cycle is required for every living being on earth to survive.

Both the ATP and the NADPH are required by the Calvin cycle. It occurs in the chloroplast stroma of the plants. Calvin cycle uses more amount of ATP than the NADPH and produces roughly same amount of both the energies. Photosynthesis may revert from the noncyclic to the cyclic electron flow and it produces more ATP than NADPH.

Class Domain Family Genus Kingdom Order Phylum Species Taxonomy hominidsix kingdom system This is the study of grouping and nami
agasfer [191]

Your answers would be:

1. Taxonomy

2. Genus

3. Species

4. Phylum

5. Class

6. Order

7. Family

8. Kingdom

9. Domain

10. Six Kingdom System

11. Hominid

1.Taxonomy is the practice of categorizing organisms and naming them. All organisms are classified into specific groups and are then given a scientific name.

2. Genus is one of the more specific grouping and it is the genus that makes up the first part of the scientific name. The organisms are grouped based on their characteristics, traits, qualities and/or features.

3. Species is the most specific among all classifications. It is distinguished though as the group that categorizes organisms based on their ability to reproduce with each other.

4, Phylum is one of the broader categories/groups. They distinguish the different organisms based on their characteristics also but are not as specific. It divides the different kingdoms into smaller groups. For example, Kingdom Animalia would have phylum chordata which includes all vertebrates.

5. Class divides phylums down into more specific features. For example, phylum chordata is divided further into classes such as mammalia (mammals), reptilia (reptiles), Aves (birds), amphibia (amphibians), and the like.

6. Order again, is more specific. It divides classes into different groups once again. So for example, for humans, we are classified as Class mammalia and then we belong in the order of primates.

7. Family on the other hand comes after order. It is more specific and comes right after order. Again, using humans as an example, our family is hominidae, which puts organisms that are distinguished for their ability of walking upright.

8. In the Linean biological taxonomy the highest classification was Kingdom. In his classification system, organisms were divided into only 3 kingdoms. As technology and discovery expanded, we have added to it.

9. Domain is the higher rank than kingdom. It is the broadest among all. There are three main domains now, we have Eukaryota, Arachaea, and Bacteria. In the old system

10. The 6 Kingdom System is the most recent classification system. The organisms are divided into 6 kingdoms:

  • Animals
  • Plants
  • Protists
  • Fungi
  • Archaebacteria
  • Eubacteria

11. Hominid is a member of Hominidae family. These are species that share about 97% similarity to the DNA of the modern human. The species included in the hominid family have simple cultures and have a capacity to communicate through language.
