If the blood cell (hypotonic) is placed inside the 30% solute solution (hypertonic), then the cell will become smaller in the size (shrink) because of the osmotic pressure.
What are hypotonic and hypertonic solutions?Hypotonic solutions have lower solute concentrations compared to the hypertonic solution with a higher solute concentration. The blood cells have a hypotonic environment on their inside as it contains 0.9 % solute concentration.
The outer of the cell has a 30 % solute concentration making it hypertonic and hence the water from the cell will move out into the more concentrated solution making the cell shrink in the size.
Therefore, the blood cell will shrink in hypertonic solution.

Answer:
Nucleic acids are the organic materials present in all organisms in the form of DNA or RNA.
These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of sequences.
Explanation:
“DNA is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic instructions from parents to offsprings.”
DNA is known as Deoxyribonucleic Acid. It is an organic compound that has a unique molecular structure. It is found in all prokaryotic cells and eukaryotic cells.
The four roles that DNA plays in the cell are:
(1) storage of information via the genetic code so that cellular processes can be initiated and maintained.
(2) the generation of genetic variation through mutation and recombination.
(3) The copying and replication of genetic information so that it can be passed onto daughter cells. It is this function that makes DNA the molecule of inheritance.
(4) gene expression. The transcription and translation of genetic material to produce proteins, enzymes and other gene products necessary for growth and life.

The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.learn more about action potential here: brainly.com/question/6705448

Two genes are 14 map units apart on the X chromosome. What percent of the father's gametes will be recombinant
Two genes are separated by 14 map units on the X chromosome. The percentage of the father's gametes that will be recombinant is 30%.
How is the recombination rate calculated?To assess the occurrence of the permutation, the rate of recombination between two genes is determined. As the ratio is multiplied by 100, the value expresses the percentage of recombinant gametes in the total gametes. Thus, if the recombinant gametes make up 30% of the total, the recombination rate is 30%.
With this information, we can conclude that Parental Gametes are formed even if there is no recombination and appear in greater numbers. Recombinant Gametes are formed only if there is an exchange and appear in smaller numbers.

If mutant HMGN2 proteins were unable to bind their substrate and then erroneously mobilized to nucleoli, these proteins would be found in the sites of Ribosome production.
In this case, mutant HMGN2 proteins deploy inadvertently to nucleoli. The nucleolus, a bulky, globular structure inside the nucleus of eukaryotic cells, houses ribosomal DNA. Here, the pre-ribosomal RNA (rRNA) gene is solely translated into a single template that is then processed to produce mature rRNA by RNA polymerase I. As a result, the nucleolus is the only location where RNA polymerase I can work.Additionally, ribosomal subunit maturation and assembly take place in the nucleolus. The cytoplasm produces ribosomal proteins from mRNA, which are then carried into the nucleolus where they interact with newly produced rRNA to generate the precursors to the 40S and 60S subunits.learn more about HMGN2 proteins here: https://brainly.com/question/884041
