Answer:

This is an example of natural selection in action.

Explanation:

    The action of natural selection consists in selecting individuals more adapted to a given ecological condition, eliminating those disadvantaged for that same condition. The most appropriate expression refers to the greater probability of a given individual surviving and leaving descendants in a given environment.

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.

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.

Charophytes are freshwater algae, closest living relatives of land plants, but they are not seedless vascular plants. Instead, they share some features with land plants. They are not ancestors of green algae, both groups descend from a common ancestral line.

Charophytes are a group of fresh water algae and they are the closest living relatives of land plants. They do share some features with land plants, such as spores surrounded by sporopollenin and alternation of generations. However, they are not seedless vascular plants; vascular plants have a complex vascular system which charophytes lack. Additionally, charophytes themselves are not ancestors of green algae; both charophytes and green algae descend from a common progenitor.

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.

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.

Answer:

The correct answer is - Hue.

Explanation:

Hue and color are related to each other as hue is one of characteristic or property of the color. Hue is basically a tint or shade of a particular color. Hue is the tint of a dominant color.

The extent to which a stimulus can be similar or different to a particular stimulus that is described as red, yellow, blue and green. Hue is part of the color and the human eye can distinguish 150 hues approximately.

Thus, the correct answer is - Hue.

The attribute of color corresponding to names like red, green, and blue is known as hue. Hue relates to the wavelength of light that is perceived by the human eye and is used to classify colors. Hue is a fundamental aspect when considering color in any visual materials.

The aspect of color that corresponds to names such as red, green, and blue is hue. Hue is the wavelength of a given color and is the attribute of color that allows us to classify it by names. It represents the colors that we most commonly associate with objects and concepts. For instance, the color red is often tied to strong emotions and physiological responses, such as increasing respiration and blood pressure. Similarly, blue is known for its calming effects, often associated with the sky and the ocean. However, there are many shades and tints of blue, like aquamarine, baby blue, navy blue, and royal blue, each with its own specific hue. Green typically represents life or nature, but it can also signify envy or inexperience.

Understanding hue is fundamental when creating visual materials such as maps, where the three primary aspects of color hue, value, and saturation must be considered. The primary colors red, yellow, and blue are also referred to as hues, and they serve as the foundation from which all other colors can be mixed.

Creeping thistle continuously survives through easy germination of seeds. The Creeping thistle seed can be buried in undisturbed soil for over 20 years and still become growable. And also, the roots help in their growth. They absorb nutrients and regenerate to form new plants. Although the roots may be able to penetrate some meters down, most regeneration occurs within or just below the plow layer. Portions of the adjacent roots become thick due to the developing storage tissue which is where new shoots are formed.

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.

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.

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.

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.
