Why would a group of small cells help an organism maintain homeostasis better than one large cell? A. They have more cell structures. B. They have a lower surface-to-volume ratio. C. They have a greater surface-to-volume ratio. D. They have a greater volume.

Answers

Answer 1

A critical part of homeostasis is the tranfer and intake of molecules (whether necessary or not). It is important for the cell to be able to bring necessary nutrients immedriately where it needs to and to be able to dispose of harmful byproducts of the cell process. It is equally important to be able to regulate water concentration. Smaller cells have a bigger surface relative to their volume (their surface scales with R^2 while their volume with R^3 where R is the radius of a cell) and thus exchanges along the cell membrane are favored in comparison to larger cells that need a lot of exchanges but have proportionally less membranes area. While A is not necessarily true, C is definitely true and thus the correct answer.

The client with cardiac failure is taught to report which symptom to the physician or clinic immediately?

Answers

In a patient with cardiac failure, the most overbearing symptom that should prompt the patient for consult is persistent coughing. Persistent coughing is a symptom of pulmonary congestion because of left sided heart failure. There is back flow of blood from the left ventricle to the pulmonary circulation and eventually there will be pooling of blood in the lungs, causing congestion and edema. This patient will present with persistent coughing accompanied with pink and frothy sputum.

Floyd has just learned about the fluid mosaic model that describes the structure of a cell’s plasma membrane. Which image of an everyday item most closely resembles the model?
-Sandwhich
-metal spring
-swiss roll
-electric wire
*PLEASE HELPP*

Answers

Answer:

The sandwich is the close representation of the fluid mosaic model which explains the structure of the plasma membrane.

Although the sandwich model is not completely correct, in the given options, the most closely related model is the sandwich model. The metal spring, swiss roll, and electric wire don't share many similarities to the fluid mosaic model.

Explanation:

According to the fluid mosaic model, the lipid bilayer membrane has embedded proteins that allow the transportation of molecules inside/outside the cell. The model was proposed by SJ Singer & G. L. Nicolson in 1972. Previously, it was believed that the structure of the cell membrane is closely related to a sandwich in which two protein layers embed the lipid bilayers. This model was proposed by Davson and Danielle.

The correct image that most closely resembles the fluid mosaic model of a cell's plasma membrane is the Swiss roll.

The fluid mosaic model describes the plasma membrane as a bilayer of phospholipids with embedded proteins that float freely in the lipid layer, much like icebergs in a sea of lipids. This model emphasizes the fluid nature of the lipid bilayer and the mosaic-like distribution of proteins.

Here's why the Swiss roll is the best analogy among the options provided:

- Sandwich: This might seem like a good analogy because a sandwich has layers, but it does not capture the fluidity of the membrane or the distribution of proteins.

- Metal spring: While this option might suggest flexibility, it does not represent a bilayer structure or the distribution of proteins.

- Swiss roll: This option is the most accurate because the Swiss roll consists of layers (like the phospholipid bilayer) with a filling that can be thought of as the proteins and other molecules embedded within the membrane. The rolling nature of the Swiss roll also suggests a certain degree of flexibility, which is a characteristic of the fluid mosaic model.

- Electric wire: This does not resemble the fluid mosaic model as it is linear and does not have a bilayer structure.

Therefore, the Swiss roll is the everyday item that most closely resembles the fluid mosaic model of a cell's plasma membrane.

In order to reproduce, many flowering plants use external agents, such as insects or birds, to aid in the pollination process. What function do the color and odor of the flowers provide for the flowering plants?

Answers

They attracted pollinating insects.

In order to reproduce, many flowering plants use external agents, such as insects or birds, to aid in the pollination process. The plants put out colorful and fragrant flowers to attract the insects to aid in the pollination process. Insects like butterflies are highly sensitive to the bright colors. They get attracted to the flower on seeing the bright color. Birds are sensitive to both color and odor. They visit those plants that either have colorful or fragrant flowers. Thus become carriers of the pollen grains and cause pollination.

What happens if you place human red blood cells in a concentrated salt solution

Answers

They shrink as water moves from inside to outside the cells as a result of osmosis.

Answer:

The red blood cell shrinks

Explanation:

According to the question, the solution the red blood cell was placed in has a concentrated salt solution, this implies that the solution is hypertonic i.e. high solute concentration in relation to the blood cell, or otherwise the red blood cell's content is hypotonic i.e. low solute concentration in relation to the extracellular solution.

Due to this difference in concentration between the cell and the external solution, an osmotic flow occurs. Osmosis is the movement of water from a region of low solute concentration/high solvent concentration to a region of high solute concentration/low solvent concentration through a semi-permeable membrane, which in this case is the membrane of the red blood cell. This osmotic gradient causes water to flow out of the red blood cell (where the solute concentration is low) to the extracellular solution (where the solute concentration is high).

Hence, the red blood cell loses water and shrinks or reduce in size.

How does continental drift affect living organisms? how does continental drift affect living organisms? it causes changes in habitats, such as when large amounts of shallow marine habitat were lost in the formation of pangaea. all but one of the listed responses are correct. it happens so slowly that it does not affect living organisms. it causes climate change, which puts selective pressure on organisms. it may cause an increase or decrease in competition among different species?

Answers

Continental drift is the large scale motion of continents across the Earth's surface driven by plate tectonics. The option that is INCORRECT is it happens so slowly that it does not affect living organisms. Continental drift is indeed a slow process but it has accompanying effects that may affect living organisms. An example is the extensive lava flows that form the present day Deccan Traps. This large eruption of lava flows marks the beginning of the the Permian Extinction.

Continental drift is a slow process that occurs over millions of years. While its effects may not be immediately noticeable, they have shaped the distribution and evolution of life on Earth. It is important to understand these impacts to better comprehend the history and diversity of living organisms.

Continental drift, also known as plate tectonics, is the movement of Earth's continents over time. It has a significant impact on living organisms in several ways:

1. Changes in Habitats: Continental drift causes the continents to shift and collide, resulting in changes in the distribution of land and water. As a result, habitats can be altered, such as the loss or gain of land for certain species. For example, when the supercontinent Pangaea formed, large amounts of shallow marine habitat were lost. This change in habitat can affect the availability of resources and the survival of different species.

2. Climate Change: The movement of continents can influence global climate patterns. As landmasses shift, they can affect ocean currents, wind patterns, and the distribution of heat and moisture across the planet. These changes in climate can put selective pressure on organisms, forcing them to adapt or face extinction. For instance, the movement of continents can lead to the formation of mountains, which can impact rainfall patterns and create different ecosystems.

3. Competition Among Species: Continental drift can also impact the competition among different species. When continents separate or collide, it can create barriers that restrict the movement of organisms and lead to the evolution of distinct species. Additionally, the merging of previously isolated ecosystems can result in increased competition for resources, potentially leading to the displacement or extinction of certain species.

If you wanted to design a drug to prevent prokaryotic cells from attaching to substrates, which structure should the drug attack?

Answers

Final answer:

To design a drug that prevents prokaryotic cells from attaching to substrates, one should target structures like the capsule, pili, or fimbriae, which are responsible for adherence.

Explanation:

If you wanted to design a drug to prevent prokaryotic cells from attaching to substrates, you should target structures responsible for adherence such as the capsule, pili, or fimbriae. The capsule allows cells to attach to surfaces in their environment and is involved in the formation of biofilms. Fimbriae also play a critical role in the attachment process to host cells. Pili, while mainly involved in genetic material exchange during conjugation, also assist in attachment to surfaces

Therefore, a drug targeting the synthesis or function of these structures could potentially prevent prokaryotic attachment to substrates. However, it is crucial to consider the natural resistance mechanisms such as target modification and prevention of cellular uptake or efflux, which bacteria might evolve against such drugs.

The Answer to question number two is the sun

1. Nitrogen fixation is an essential process as the plants do not possess the tendency to use nitrogen in the form of N2. The bacteria known as nitrogen-fixing bacteria convert atmospheric nitrogen in the soil to ammonia, which can then be taken up by the plants.

2. The process of the water cycle is mainly driven by the energy provided by the Sun. This solar energy mediates the cycle by evaporating water from the lakes, oceans, rivers, and even the soil. Other water moves from plants to the atmosphere via the procedure of transpiration.

You car see the full concept map below.

Plants perform photosynthesis. They use the sunlight, that provides them with energy, and take the carbon dioxide from the atmosphere.

The main role of chloroplasts is to conduct photosynthesis.
They have chlorophyll, which is a green pigment that captures the energy from sunlight.

Photosynthesis is a way for them to make their own food (sugars), necessary for them to stay alive and to produce oxygen. Both will be needed for their cellular respiration, a process that occurs in the mitochondria, and will produce energy, in the form of ATP, and CO2.

The carbon dioxide that they produced can be used for doing photosynthesis.

Plants perform photosynthesis to produce sugars and need to break them down for cellular work. This process involves the interrelatedness of sugar production and breakdown in plant cells.

Plants perform photosynthesis to convert light energy into chemical energy in the form of sugars. However, plants also need to break down these sugars to fuel cellular work. The process of sugar production and breakdown in plant cells is interconnected and allows plants to carry out essential functions.

Photosynthesis:Light energy is absorbed by chlorophyll in plant cells.Water molecules are split, releasing oxygen as a byproduct.Carbon dioxide from the atmosphere is converted into sugars (glucose) in the chloroplasts.Respiration:During respiration, sugars are broken down in the plant cells' mitochondria, releasing energy.This energy is used by the plant for various functions, such as growth, reproduction, and cellular activities.Carbon dioxide, a byproduct of respiration, is released into the atmosphere.

What major benefits do plants and mycorrhizal fungi receive from their symbiotic relationship?
a. plants receive sugars, and fungi receive nitrogen.
b. plants receive micronutrients, and fungi receive sugars.
c. plants receive macronutrients, and fungi receive micronutrients.
d. plants receive nitrogen and phosphorus, and fungi receive sugars?

Answers

The correct answer could be both b: 'plants receive micronutrients, and fungi receive sugars' and d: 'plants receive nitrogen and phosphorus, and fungi receive sugars'. In this mutualistic association, plants provide a relatively constant supply of carbohydrates derived through photosynthesis. The fungi are able to mobilise soil minerals that are unavailable to the roots of the plants such as phosphate, nitrate and and micronutrients such as iron.

Final answer:

The correct option is d. plants receive nitrogen and phosphorus, and fungi receive sugars. Plants receive nutrients like phosphorus and other minerals through their symbiotic relationship with mycorrhizal fungi, which in turn receive sugars from the plant. This mutualism also boosts plant defenses and helps in poor soil conditions.

Explanation:

The major benefits that plants and mycorrhizal fungi receive from their symbiotic relationship are as follows: plants obtain essential nutrients like phosphorus and other minerals such as zinc and copper from the soil, while the fungi receive sugars from the plant roots. The mycorrhizae help increase the surface area of the plant root system by spreading fungal hyphae beyond the root's immediate nutrient-depleted zone, hence allowing the plant to access nutrients like phosphorus which would otherwise be unavailable. For the fungi, this relationship is beneficial as they can obtain a significant portion of their required carbon from the sugars translocated by the plant.

In addition to nutrient exchange, mycorrhizae serve as a physical barrier to pathogens and may stimulate the plant's generalized defense mechanisms, which can include the fungi producing antibiotic compounds. This symbiosis is particularly effective in soils that are poor in nutrients, and the fungi also help protect the plants from soil with high metal concentrations by acting as a buffer and allowing the plants to thrive in such harsh environments.

Membrane proteins, like membrane lipids, can move laterally by exchanging positions with other membrane components. which type of membrane proteins is expected to be the least mobile, based on their function?

Answers

There are choices for this question namely:

a. channels
b. anchors
c. receptors
d. enzymes

The correct answer is "anchors". Lipid-anchored proteins (i.e. glycosylphosphatidylinositol-linked proteins or GPI-linked proteins) are proteins that are anchored to lipids to limit the movement of the cell; therefore these proteins are the least mobile of all the proteins in the choices. Channels, receptors, and enzymes are not anchored in any way to other molecules.

Integral membrane proteins are least mobile due to their important roles and connections within the cell membrane.

The type of membrane proteins that is expected to be the least mobile, based on their function, are integral proteins. Integral proteins span the hydrophobic interior of the lipid bilayer and may have specific functions such as forming channels for ions, or acting as receptors or enzymes. Their lateral mobility can be restricted due to their direct connection to the cytoskeleton, interactions with lipid rafts, or because they are anchored within the membrane, which is necessary for their specific functions.

Question 7(Multiple Choice Worth 3 points) (06.02 LC) Which of the following does the endocrine system regulate? Blood sugar Reflexes Respiration Senses

Answers

Question 1:

Endocrinology refers tot he branch of physiology and medicine that deals with the endocrine glands and hormones. While the transplantation of normal genes into cells in place of missing or defective ones are referred to as gene therapy.

On the other hand, sports medicine involves prevention and treatment of injuries that are related to sports and exercise.

Since all three does not concern with the brain and its functions, the remaining option is neuroscience or the study of the human nervous system, which includes the brain.

Question 2:

Homeostasis is defined as any self-regulating process where the biological system tends to maintain stability while adjusting to conditions that are optimal for survival.

In the choices above, the endocrine does its function in maintaining homeostasis in the first case, where the pain stimulus is detected and a signal was sent to the brain, for the automatic response.

Question 3:

The adrenal, parathyroid, thyroid and pituitary glands are all parts of the endocrine system. When the 12-year-old Raj fell behind the growth chart, his endocrine system was affected by the pituitary gland.

It is a very small gland, comparable to a pea, which produces and releases growth hormones into the body.

Question 4:

"Flight or Fight", also referred to as the "stress hormones" is the physiological reaction that occurs in response to a perceived harmful event, attack or threat to survival. A person should pursue a career in endocrinology if he is interested to learn more about it.

Question 5

Hormone secretions are controlled by both the endocrine and the nervous system through a primary linked called the hypothalamus.

An example is how the nerve cells in the hypothalamus control the pituitary gland by producing chemicals that would either stimulate or suppress its hormone secretion.

The said hormone secretion is influenced by many factors (like emotion, temperature, light exposure patterns, seasonal changes, etc.) which were sensed by the brain. Then the hypothalamus would relay this information to the pituitary.

Therefore, we can say that secretion of hormones is controlled by a feedback loop.

Question 6

The secreted hormone travels from the endocrine gland through the bloodstream to the target cells designed to receive its message. In the process, special proteins that act as carriers that control the amount of available hormone to interact with and affect the target cells.

So the answer is TRUE.

Question 7

Blood sugar is being regulated by the endocrine system through the pancreas, an elongated organ located toward the back of the abdomen, behind the stomach. The pancreas has digestive and hormonal functions. It is the endocrine pancreas which produces the insulin and glucagon hormones.
