Answer:

Law of segregation can be understand that when an individual makes a gamete, gamete receives one copy a gene in it which is completely random process and can be found in each gamete that later will form in the offspring.

Independent assortment states that the alleles of two or more than two different genes get assorted into gametes, totally independent to one another.

Punnett square is the diagram representation of the prediction of the genotypes of a particular breeding experiment. This predictions are used to the show on the basis of of both the laws stated above. In the punnett square the alleles of each gamete are segregated and represented outside of the box on right side and above the box.

The each inner box is get one copy of the alleles from both the side independently of one other.

Answer:

Law of segregation states that at the time of the gamete formation, in a pair of the contrasting trait only the single trait will pass down to the next generation so that each gametes receive only one trait.

Law of independent assortment states that the alleles of the different gene will assort independently and do not depend on each other for their segregation.

The punnet square is used for the representation and the calculation of the different phenotype and genotype of the organisms.

7. one molecule of dietary glucose can be oxidized through glycolysis and the citric acid cycle to generate a maximum of 32 mole
Dmitry [639]

6.25% of the energy contained in glucose is lost during the storage process. Glycolysis produces the molecules that are processed by the citric acid cycle.

  • Each dietary glucose molecule produces 32 molecules of ATP when it enters the glycolysis and oxidation pathways directly.
  • A net 2 ATP are produced during glycolysis for every gram of glucose. Per glucose, the citric acid cycle generates an extra 2 ATP. 28 ATP are produced by oxidative phosphorylation using the byproducts of glucose catabolism.
  • 32 ATP molecules are created in this way. A cell could potentially store dietary glucose for later use, in the form of glycogen.
  • One ATP must be used in this process in order to create glucose-1-phosphate (G1P).
  • After then, G1P and UTP (uridine triphosphate) combine to form uridine-diphospho-glucose (UDP-glucose or UDPG). The UTP substrate, which is used in this phase, indirectly consumes ATP.
  • Glycogen synthase can then utilise UDPG directly in the production of glycogen. This implies that each additional molecule added to a glycogen polymer uses up two ATP molecules.
  • If two ATP molecules are used up during the storage of glucose as glycogen, then 2/32 or 6.25% of the energy contained in glucose is lost during the storage process.

Scientists use a standardized taxonomic system to separate organisms into hierarchical groups based on similarities and differen
Alla [95]

Answer:

Option B, It allows different kinds of organisms to be easily identified based on their characteristics

Explanation:

Options for the question are

  • It provides a detailed evolutionary history of all the known organisms on Earth
  • It allows different kinds of organisms to be easily identified based on their characteristics
  • It allows scientists to group organisms based on their personal preference
  • It prevents people who are not scientists from studying and identifying organisms.
  • It allows scientists to to group organisms based on their personal preference
  • It prevents people who are not scientists from studying and identifying organisms ​

Solution

A standardized taxonomic system provides a common basis for the entire scientist community to identify and classify organism on common grounds and hence leading to a standardized organism classification across the globe.  

This also groups organisms into different kingdoms, taxas and classes with defined hierarchy and description of shared traits and characteristics. It also provides scope for inclusion of newly discovered species thereby making the standardized taxonomic system flexible  

Hence, option B is correct

A child has been born prematurely and is experiencing severe asthma like symptoms. Exposure to what most likely affected cell di
Debora [2.8K]

Answer: Carbon monoxide

Explanation:

Carbon monoxide is a gas that is tasteless, colorless, and odorless, that is formed when wood, charcoal, gasoline is burnt.

When breathed in, carbon monoxide is harmful as it displaces the oxygen that is in the blood and this leads to the deprivation of the brain and other vital parts of the body of the oxygen that's is required for daily functioning.

Exposure to carbon monoxide is most likely affected cell differentiation in the growing embryo. When the pregnant woman inhales smoke, this affects the oxygen in the baby's bloodstream as it's being replaced by carbon monoxide and there's shortage of oxygen.

This affects the cell differentiation in the growing embryo and can lead to the child been born prematurely and can also lead to severe asthma like symptoms.

What advantage does the phylogenic classification system have over the Linnaean system?
PtichkaEL [24]
<span>The answer is B. It depends on developmental family and produces trees called cladograms. Cladistics likewise recognizes clades, which are gatherings of life forms that incorporate a progenitor species and its relatives. Ordering life forms on the premise of drop from a typical precursor is called phylogenetic characterization.</span>
