What would you expect to see in a blood sample of a person who has drowned in salt water? explain in terms of osmosis?

Answers

Answer 1
The red blood cells would look just fine or normal in the person who has drowned. Water wouldn't be lost because it wouldn't be attracted to the concentration of the salt water and the salt water would be too large to break the barriers.
Answer 2

Answer:

I would expect to see a withered cell because of the extreme lack of water.

Explanation:

Osmosis is the passage of solvent from a less concentrated solution to a more concentrated solution through a semipermeable membrane until the pressure exerted by the solution on the membrane prevents the passage of solvent. This process aims to balance the concentration of the solution.

Based on this, we can imagine what happens to the cells of a person who drowned in salt water.

Salt water has a higher salt (solute) concentration than human cells, so through osmosis the human cell provided a water outlet (solvent) to dilute the salt of the salt water and establish a balance between the medium. cell phone and salty water. With this extreme loss of water, human cells become wilted and collapse.

Slopes that drop or rise sharply in elevation are:

Answers

Final answer:

Steep slopes are geographical features that rise or drop significantly in elevation over a short distance. Examples are found in mountainous areas or cliffs by the sea.

Explanation:

Slopes that drop or rise sharply in elevation are commonly referred to as steep slopes. These geographical features are characterized by an abrupt change in altitude, with the land rising or falling significantly over a short distance. Steep slopes occur naturally in mountainous or hilly areas. A cliff by the sea, or the side of a mountain range, are good examples of this geographical feature. They're significant because they influence elements like climate, vegetation, and human habitation, as living or farming on a steep slope can be challenging.

Final answer:

Steep slopes, in mathematical terms, are represented by a plate with a high positive or negative slope. In geographical context, these are typically found in mountain areas where erosion forms sharply rising or falling landscapes.

Explanation:

Slopes that drop or rise sharply in elevation are referred as steep slopes. In the context of a graph or a line in mathematics, these are represented by lines with a high positive or negative slope. The slope is defined by how much y (vertical distance) changes for each unit of x (horizontal distance) or 'rise over run'.

In geographical terms, steep slopes are commonly found in mountain ranges, where erosion by water and ice create sharp peaks and serrated edges. For example, a mountain formed by upthrusting of the crust will have its rocks subject to erosion, resulting in a steep slope. These are visibly different to the smooth, dull slopes found on non-eroded surfaces such as those found on the Moon or Mercury.

Which of the following is the best example of a positive correlation

Answers

Your chances of getting an A increase as the difficulty of the test decreases. Hence the correct option is b.

A positive correlation implies that as one variable increases, the other variable also increases. In the provided example, the statement "Your chances of getting an A increase as the difficulty of the test decreases" exemplifies a positive correlation. This suggests that when the difficulty level of a test decreases, the likelihood of achieving an A grade increases.

As the complexity of the test diminishes, students are more likely to perform well, leading to higher grades. This positive relationship between the ease of the test and the likelihood of obtaining an A aligns with the concept of a positive correlation, where the variables move in the same direction, reinforcing the idea that easier tests are associated with higher grades.

State one possible reason why a gene for the production of a human hormones would be placed in bacterial DNA

Answers

You can introduce the gene into bacteria in order to allow the bacteria to produce more of the hormone.

A gene for human hormone production might be inserted into bacterial DNA to facilitate the large-scale, industrial manufacture of hormones such as insulin and human growth hormone using recombinant DNA technology, avoiding allergic reactions from animal-sourced hormones.

One possible reason why a gene for the production of a human hormone would be placed in bacterial DNA is to manufacture the hormone on an industrial scale using recombinant DNA technology. This process has been used successfully as early as 1978 to produce human insulin, which is critical for treating diabetic patients. Using Escherichia coli (E. coli) bacteria as hosts, the human hormone genes, such as the one for insulin or human growth hormone (HGH), are inserted into the bacterial DNA, enabling bacteria to produce these hormones. This method eliminates allergic reactions that some patients experience when treated with hormones obtained from animals, such as pig insulin, and it allows for the mass production of hormones that are identical to those naturally produced by the human body.

If a cell were treated with a poison to block to function of its mitochondria, which of the following would be the likely result?

Answers

Mitochondria are generally known as the "powerhouses" of a cell because it uses the food within the cell to create ATP, or energy. So, if the mitochondria were damaged or prevented from working properly, that means the cell would not be able to convert food into energy as effectively or efficiently as it would if everything were working properly. This could lead to symptoms like low energy, inability to stay warm, inability to think normally, inability to digest and metabolize food efficiently, etc; basically, anything that requires any energy could be affected with damage to mitochondria

List and define major chemical bonds used to connect biological molecules

Answers

Ionic boning involves a transfer of an electron, so one atom gains an electron while one atom loses an electron. One of the resulting ions carries a negative charge (anion), and the other ion carries a positive charge (cation). Because opposite charges attract, the atoms bond together to form a molecule.
The most common bond in organic molecules, a covalent bond involves the sharing of electrons between two atoms. The pair of shared electrons forms a new orbit that extends around the nuclei of both atoms, producing a molecule. There are two secondary types of covalent bonds that are relevant to biology — polar bonds and hydrogen bonds.
Two atoms connected by a covalent bond may exert different attractions for the electrons in the bond, producing an unevenly distributed charge. The result is known as a polar bond, an intermediate case between ionic and covalent bonding, with one end of the molecule slightly negatively charged and the other end slightly positively charged.
Because they’re polarized, two adjacent H2O (water) molecules can form a linkage known as a hydrogen bond, where the (electronegative) hydrogen atom of one H2O molecule is electrostatically attracted to the (electropositive) oxygen atom of an adjacent water molecule.

Explanation:

Tina has a history of asthma. what sounds might you hear during an asthma exacerbation?

Answers

Final answer:

During an asthma exacerbation, wheezing and possibly crackling sounds may be heard, along with decreased breath sounds if the attack is severe.

Explanation:

These sounds include wheezing, which is a high-pitched whistling sound caused by the restriction of airflow, and is most pronounced when exhaling.

Additionally, during more severe attacks, a health professional might hear decreased breath sounds due to reduced air movement within the lungs. In some cases, a crackling sound can be heard, suggesting the presence of mucus in the airways. It is also possible to encounter signs of increased work of breathing such as the use of accessory muscles during respiration.

Asthma is a chronic respiratory condition where the airway passages narrow and are often accompanied by excessive mucus production, leading to symptoms such as difficulty breathing, coughing, and chest tightness. Triggers like allergens, air pollution, infections, and exercise can provoke these asthma attacks.

Prompt and proper management of an asthma attack, especially if presenting severe symptoms such as cyanotic lips or confusion, is imperative for an asthmatic individual, and may involve the use of fast-acting medications like bronchodilators.
