Use your knowledge of osmosis to explain why the mass of each cube increased.

Answers

Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass

The mass of each potato cube increased because they have gained water by osmosis.

Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.

A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).

Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?

Answers

Answer:

Part D: pilus

Explanation:

Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.

The structure in bacteria that allows them to exchange genetic material and evolve is the pili

Bacteria pili

Pili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:

they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugation

When genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

22. Why do you think the sea urchin was chosen to test the effect of changes in pH?

Answers

Answer:

as it settles deeper underwater ph tends to be higher and a sea urchin tends to be more resilient to change

Acidic seawater, at current pH levels found in the world's oceans, can have a negative impact on sea urchin larval development so it is taken to test the effect of changes in pH.

What is sea urchin?

Sea urchins are spiny, globular echinoderms of the Echinoidea class. The urchins were able to compensate for internal pH in modest acidification (pH 7.8) and not in higher acidification (pH 7.6).

The pH of coelomic fluid was lower at higher temperatures.

Thus, due to this, the sea urchin was chosen to test the effect of changes in pH.

Answers

Answer:

B. identifying the regions of human DNA that are transcribed into RNA

C. identifying the regions of human DNA that bind to proteins

D. analyzing the regions of human DNA that vary among individuals

Explanation:

The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.

Transcription is the process of mRNA synthesis. It occurs in the nucleus before translation. During transcription, RNA bases pair DNA bases, replacing Thymine with Uracyl. You will find the example in the explanation.

Note: The DNA sequence is missing, so I will provide a new sequence and explain the procedure. I suggest you perform the same steps with your molecule fragment and reach the correct mRNA.

Protein synthesis

Proteins synthesis is done in two stages: transcription and translation.

The whole process begins in the nucleus and finishes in the cytoplasm.

Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.

Once the new molecule is completed, it is sent to its final destiny.

Transcription:

The first step before protein arrangement is to synthesize messenger RNA, mRNA.

This is the transcription process and occurs in the nucleus.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.

The coding strand goes in direction 5' to 3', while the complementary strand -template strand- grows in direction 3' to 5'.

This last segment is the one that is going to be complemented by the mRNA. It is the template strand.

A template DNI strand is read in direction 3'→ 5' to build the mRNA molecule that grows in direction 5'→ 3'.

During transcription bases forms pairs. RNA replaces Thymine with Uracyl, so pairs are as follows,

DNA mRNA

Adenine pairs Uracyl, Thymine pairs Adenine, Guanine pair Cytosine, Cytosine pair Guanine.

Translation:

Translation occurs in the cytoplasm.

During translation, rRNA reads mRNA in 5' to 3' direction, and tRNA adds the correct amino acid to the growing chain.

The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.

Example

We will consider for this example the following DNA template strand.

DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'

Transcription

template DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'

mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´

The new mRNA strand is

mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´

Once the mRNA synthesis is over, the molecule leaves the nucleus and proceeds with translation in the cytoplasm.
