List and define major chemical bonds used to connect biological molecules

Answers

Answer 1
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.

A client who weighs 176 pounds is receiving an iv infusion with esmolol hydrochloride (brevibloc) at 48 ml/hour. the iv solution is labeled with the concentration of brevibloc 10 mg/ml. how many mcg/kg/minute is the client receiving?

Answers

Convert pounds to kg by dividing 176 pounds by 2.2 pounds = 80 kg. Convert the IV concentration from mg to mcg. 1 mg : 1000 mcg :: 10 mg : 10,000 mcg. Infusion rate (48 ml/hour) x concentration (10,000 mcg/ml) divided by 60 minutes/hour x 80 kg = 48 x 10,000 divided by 60 x 80 = 480,000 / 4800 = 100 mcg/kg/minute

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

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:

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.

Nummular is a term to describe a lesion size. Nummular size is about a coin size, or 3cm x 5cm. Other sizes could be miliar which was about a dot, lenticular which was around a lentil, and plaque which sizes around a palm of the hand. This size description is not really descriptive since it has various ranges. Actual size in centimeter unit might be better to describe a lesion.
Final answer:

A nummular lesion refers to a round or coin-shaped medical or dermatological lesion seen in certain skin conditions, including nummular eczema.

Explanation:

A nummular lesion is a terminology used in medicine and dermatology to describe a lesion that is round or coin-shaped. The term 'nummular' is derived from the Latin word 'nummulus,' which means 'coin.'

A patient states to the nurse, "isee headless people walking down the hall at night" which nursing response is appropriate

Answers

It is important for a nurse to reinforce reality to a client so the appropriate response is "Some people may see or visualize things that others may not see."

The correct nursing response to a patient stating, "I see headless people walking down the hall at night" would be to validate the patient's feelings and provide reassurance while also assessing for any underlying causes of the hallucinations.

When a patient reports experiencing visual hallucinations, such as seeing headless people, it is important for the nurse to approach the situation with empathy and concern. The nurse should first acknowledge the patient's experience and provide reassurance that the patient is safe. This can be done by responding with statements like, "I understand that what you're experiencing can be very frightening. I want to assure you that you are safe here with us."

Next, the nurse should perform a thorough assessment to identify any potential causes for the hallucinations. This could include reviewing the patient's medication regimen for any drugs that may cause hallucinations as a side effect, evaluating for delirium due to an underlying medical condition, assessing for psychiatric conditions such as schizophrenia or dementia, and considering environmental factors like lighting or sleep disturbances.

The nurse should also document the patient's report and communicate the findings to the healthcare team to determine the appropriate interventions. Depending on the cause, interventions may include medication adjustments, treatment of underlying medical conditions, environmental modifications, or referral to a mental health specialist.

It is crucial to maintain a calm and supportive demeanor throughout the interaction to build trust with the patient and ensure they feel heard and supported. The nurse's response should be non-judgmental and should avoid minimizing the patient's experience. Instead, the focus should be on ensuring the patient's safety, providing comfort, and working towards identifying and addressing the underlying cause of the hallucinations.

how would you collect accurate and precise crocodile nest data?

Answers

To collect accurate and precise crocodile nest data, researchers can use the mark-recapture method along with GPS tracking, and employ non-invasive techniques like camera traps and DNA analysis from collected fecal samples. Establishing random sampling points and using reliable data sources alongside flagging for marker placement are key for obtaining consistent and unbiased data.

To collect accurate and precise crocodile nest data, biologists can employ several methods. The mark-recapture method is a technique where crocodiles are captured, marked with a permanent marker, and then released. The use of GPS coordinates is essential to mark sample points and ensure consistency in the data collection process over time. Non-invasive techniques, such as camera traps and DNA analysis from fecal samples, can also provide valuable information about crocodile populations without physically disturbing the nests or the crocodiles.

It is important to randomly select sampling locations using a random numbers table, ensuring the data is not biased by predetermined choices. Biologists can use a compass to find a bearing and walk a randomly selected distance to establish these sampling points. At each point, detailed habitat data is collected, and then the process is repeated multiple times across various locations.

Additionally, permanent marking of sampling locations with flagging or other markers, while being aware of the potential influence on the environment or the wildlife being studied, is a crucial step towards consistency and reliability in the data collection process. Moreover, combining different methods and cross-verifying data with reliable sources is essential to avoid potential biases and enhance the quality of the data collected.

Every bush gets 3 cups of fertilizer, but each receiving a different brand. One bush gets no fertilizer. All bushes receive morning sunlight and no afternoon sunlight. All bushes are watered the same amount every other morning. After 4 weeks, the boys observe the color of the blooms on each bush. 1. Independent variable: 2. Dependent variable: 3. Hypothesis: 4. Control group: 5. Experimental group: 6. Constants:

Answers

Independent variable: Fertilizer.
Dependent variable: Colour of the flower
Hypothesis: The type of fertilizer used for cultivation affect the colour of the hydrangea flower.
Control group: The group that did not receive fertilizer.
Experimental group: the groups that receive fertilizer.
Constants: type of soil used, amount of sunlight allowed, amount of water used to wet the flower, duration of the experiment.

Final answer:

The experiment by Connor and Miguel is set to test how the type of fertilizer affects the color of hydrangea blooms; the independent variable is the fertilizer type, the dependent variable is the bloom color, and the control group is the bush without fertilizer.

Explanation:

Connor and Miguel are conducting an experiment to determine if the type of fertilizer changes the color of hydrangea flowers. To properly analyze their experiment, we should identify various components of the experimental design.

Independent variable: The type of fertilizer used on each hydrangea bush.

Dependent variable: The color of the hydrangea blooms.

Hypothesis: If the type of fertilizer affects the color of hydrangea flowers, then using different brands of fertilizer will result in different bloom colors.

Control group: The one bush that receives no fertilizer.

Experimental group: The nine bushes that each receive a different brand of fertilizer.

Constants: The amount of sunlight (morning), the soil type, the amount of water, and the amount of fertilizer (3 cups) are all kept constant to ensure a fair test of the hypothesis.

The experiment demonstrates a scientific approach to testing the effect of an independent variable (fertilizer type) on a dependent variable (flower color), ensuring that all other potential variables remain constant. This is exemplified in the control group, where lack of fertilizer serves to show the natural color outcome without the influence of external additives.

What are two different ways a plant could control turgor pressure, a name for internal water potential within its cells? is this a sufficient definition for turgor pressure?

Answers

Plants could control their turgor pressure either by actively transporting proteins to inside or outside of the cells in order to import ions or other solutes to increase or decrease, respectively, solute concentration inside of the cell, or through leaves' evaporation changing water concentration levels within the plant.
This is not an accurate definition. Turgor pressure is about the pressure of the cytoplasmic membrane over the cell wall, which will then impact water potential depending on the the pressure, whether is negative or positive.

Turgor pressure is defined as the pressure exerted by the fluid in the cell, which presses cell membrane against the cell wall. The turgor pressure in plants is generated through osmotic inflow of water into cells.  

The plants control turgor pressure in two ways:

1. The plants actively transport the proteins to inside and outside of the cells to maintain the pressure exerted by the fluids.  

2. The cells increase or decrease the solute concentration inside the cells. The leaves perform evaporation changing the water concentration levels in the plant.

Therefore, the turgor pressure is pressure exerted by plasma membrane over cell wall. It can be explained as the cytoplasmic membrane's pressure over the cell wall that impact water potential.
