Answer:

anatomy and neurobiology

Explanation:

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

<em>Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.</em>

<em>A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease. </em>

How does Pteromyzon differ from scolidon and labeo fishes?
Oduvanchick [21]

Answer:

Due to agnathous, no paired fins and scales.

Explanation:

Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of  scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.

Q. Which of the following are true concerning living things? Check all that apply. (2 pts)
adoni [48]

Answer:

Explanation:

Answer: 2 They are composed of molecules that contain carbon-carbon bonds.  

3. They undergo chemical reactions to use energy they acquire from the environment.  

Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms  have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.

They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.

They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.

Phantasy [73]

The country in which Joseph is living is a least developed country (LDC), also often referred to as a ''third world country''. This type of countries are the countries that are at the bottom in pretty much every parameter used for measuring the quality of the human life. The government and the public institutions are corrupt, and also available for only certain people, the infrastructure is terrible, the industry undeveloped, the economy in dire condition, education is of very low quality...

These types of countries though are the ones that have the highest fertility rates, often the average being between 6 and 8 children per woman. Unfortunately, because of the bad conditions lot of those children die as infants or in the early childhood, on top of that the life expectancy is very low, usually in the range between 40 and 50 years of age.

In a two-point linkage analysis, genes a and b have been found to be 26 m.u. apart on the same chromosome. A third gene, c, has
Anna007 [38]

Answer:

Because the two-point analysis underestimates the actual distance between A and B for not taking into consideration all the possible crossing-overs. The most accurate result is the one thrown by the three-point analysis.

Explanation:

When calculating genetic distances, we might notice a difference when using a two-point analysis and when making a three-point analysis. Their results are different. This difference is because distances between genes are not completely additive. They might vary. We can notice this difference in the exposed example, in which the map distance between <em>A and B when using a two-point analysis equals 26 map units</em>. However, <em>when using a three-point analysis, it equals 33 map units</em>. The <em>addition of distances from A to C and from C to B is 33 and not 26</em>.  

Calculating the recombination frequency between the two genes located in the extremes and far apart from each other<u> underestimate </u>the actual genetic distances between them, because there might occur other crossing-overs that were not detected. So, when calculating the genetic distance from A to B, we probably will not consider the occurrence of a double recombinant between them, and we might sub-estimate the actual distance. In between A and B many simple and double-crossing over might occur, and might not be detected by the two-point analysis.

The relationship between the actual map distance (number of crossing overs) and the recombination frequency between two loci is not lineal. The farther apart the two genes are, the worse is the distance estimation.

 The most accurate analysis is the three-point one that is based on the addition of distances between every two genes.
