When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity? a) the ions in the solution interact with the sugar and that interferes with its solubility b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water

Answers

Answer:

The correct answer is option c.he solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules

Explanation:

The Solution contains a solute (sucrose for this situation) and dissolvable (water for this situation). A saturation or unsaturation of a solution relying upon whether it can even now dissolve a solute or not.  

As indicated by this inquiry, the sucrose solution is saturated as the 0.7 M sucrose arrangement doesn't disintegrate the sucrose (solute) anymore. The immersion of the sucrose arrangement happens in light of the fact that the measure of solutes is likening the number of solvents in the solution. The solubility of a particular solution relies on saturation.

How is DNA expression regulated in individual cells?

Answers

Answer:

Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.

Explanation:

Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.

What is gene regulation?

Proteins known as transcription factors are activated by signals from the environment or from other cells.

Limiting the amount of mRNA that is generated from a certain gene regulates transcription.

Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.

Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

When there is less or no rain than expected it will lead to draughts.

Draughts:

When there is less rainfall all the parts and organisms of the earth get affected. Water is an essential component of life. Less rainfall leads to the scarcity of water on the earth.

Farmers will not get enough amount of water for farming, groundwater levels also get affected. Plant and animal life also gets affected, and this affects the survival of organisms.  Draughts can also affect the amount of water in the hydrosphere.

Food, fruits, and vegetables also get reduced because of less amount of rainfall. Therefore good rain is essential for the lives of the plants and animals. This is important for the survival and the good life of the organism.

Carbon sinks (the ocean is actually the largest carbon sink)

Atoms connected by covalent bonds share a ionic compounds. b pairs of electrons. c carbon and oxygen. d hydrogen ions.

Answers

Answer:

B

Explanation:

Atoms connected by covalent bonds share electrons. Therefore, the correct answer is option B.

Extremely high ionization energies prevent some elements from accepting electrons, and extremely low electron affinities prevent some elements from accepting them. These elements' atoms frequently share their electrons with those of other elements or with other atoms of the same element in order for both atoms to achieve stability by forming an octet configuration in their respective valence shells. Covalent bonds are those associations that involve sharing electron pairs between entities of different or similar kinds.

Therefore, a pair of electrons is shared between atoms connected by a covalent bond. The correct answer is option b i.e. pairs of electrons.

Answers

I believe the answer is
D) Tonicity

The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.

What is osmolarity of a solution?

Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.

According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.

Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.

From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.
