Weather balloons are only partially inflated before they're released into the atmosphere. why is that?

The lymph is formed by the interstitial fluid that enters the lymph capillaries. Because of its origin, the lymph varies its composition a lot as cells are constantly in exchanges with their interstitium. The lymph is then through lymphatic vessels until it gets to lymph nodes where is treated by lymphocytes. After this treatment, the lymph is then released into the bloodstream, on the subclavian veins. Because of this common tracks (ultimately the subclavian veins), and contacts (body's cells), blood plasma and lymph are so similar.

        The right answer to this question is option A. Water moves in to dilute the sugar in the bear, causing it to swell.

       That happens because there is a process involving water called osmosis. This process is pretty simple to understand. What happens is that the water will move from a place to another because of the concentration of solute. So, in this case, we have a higher concentration of solute inside the bear, and a lower one in the water, and for that, things need to be equal to reach the right balance between both concentrations. Once that happens, that water swells the gummy bear to balance these two them, and that's called osmosis.

The advantage of breathing through the nose rather than the mouth is that when using the nose, this can create a back flow of the air we exhale in the lungs rather than the mouth. And in the same time, the nose filters the dirt that we may inhale than the mouth in which it does not.

Answer:

Lose mass

Explanation:

In hypertonic solution ,the concentration of solute is greater outside the cell membrane and less inside the cell membrane.

Osmosis is a process in which solvent moves from less concentrated solution to high concentrated solution through a semipermeable membrane and thus, equalizing the concentration each side of membrane.

When we place the cell in hypertonic solution then the solvent from cell moves out due to osmosis and the cell to shrink.Therefore, the mass would be decrease.

Hence, in hypertonic solution the mass of the cell would be loss .

Answer:

C. It contains nitrogen from fertilizer that stimulates the growth of algae.

Explanation:

Nitrogen and phosphorus are the most used fertilizers in agricultural production.  And when the soil is washed, the water next to the fertilizers ends up in rivers and seas. This generates an overgrowth of algae. At death of the algae the microorganisms that break them down demands a lot of oxigen.  Lack of oxygen dissolved in water leads to the death of numerous aquatic organisms.

The impact of these algae growths is C. It contains nitrogen from fertilizer that stimulates the growth of algae.

From the information given, we're informed that the Florida Everglades have reduced in size and suffered from pollution due to overpopulation.

When runoff occurs, this will bring about a dense growth of algae forms along the water surface. The algae growths contain nitrogen from fertilizer that is vital for stimulating the growth of algae.

The answer to the statement is false. It is because the platelet count is not responsible of determining of presence of inflammation or infectious disease in the lymphatic system. The most suitable test or determination for this is the complete blood count and the white cell differential count.

The Spanish riddle is talking about the fingers on a human hand, describing each finger with different characteristics like longest, shorter, smallest, slimmest and thickest.

The riddle presented in Spanish - 'Uno larguito, dos más bajitos, otro chico (small) y flaco (skinny), y otro gordazo (fat). ¿qué son?' - is describing the characteristics of the fingers on a human hand. Here's how: 'Uno larguito' refers to the middle finger, which is typically the longest. 'Dos más bajitos' are the thumb and pinky, which are generally shorter. 'Otro chico' could be the pinky, which is usually the smallest, and 'y flaco' could be the ring finger, noted to be slimmer relative to its length. Lastly, 'otro gordazo' can be seen as the thumb, which tends to be thicker in comparison to the other fingers.

One long, two shorter, one small and skinny, one big and fat. A ladder with steps.

This riddle describes a staircase. The "uno larguito" (one long) refers to the long main part of the staircase, while "dos más bajitos" (two shorter) are the shorter steps leading to the next level.

"Otro chico y flaco" (one small and skinny) represents a thin and narrow step, and "otro gordazo" (one big and fat) signifies a broader and larger step.

Staircases commonly have one long base or central section (uno larguito) and multiple steps (dos más bajitos) that gradually ascend or descend.

Among these steps, some are narrow and small (otro chico y flaco), while others are broader and more substantial (otro gordazo).

The riddle cleverly employs descriptive terms to allude to the different elements of a staircase.

In summary, the riddle uses playful language and descriptive adjectives to lead the reader to the solution, which is a staircase.

Staircases are familiar architectural elements, making this riddle accessible and enjoyable for a wide audience.

Osmotic pressure exerts itself on the side of the selectively permeable membrane with a higher solute concentration. This pressure aims to stop the movement of water through the membrane, which occurs due to the process of osmosis attempting to equalize solute concentrations across the membrane.

Osmosis is a process by which solvent can pass through a semi-permeable membrane from an area of low solute concentration to a region of high solute concentration. Osmotic pressure is the pressure that, when applied to the region of high solute concentration, will stop the process of osmosis. Consequently, osmotic pressure exerts itself on the side of the selectively permeable membrane where the solution has a higher concentration of solute, as water moves towards this area in an attempt to equalize solute concentrations.

Different materials, including biological cell membranes and synthetic materials like dialysis tubing, exhibit selective permeation characteristics. The phenomenon of osmosis plays a critical role in biological systems as it affects how substances move through cell membranes, which are naturally semi-permeable.

Fat is a common example of lipids. Lipid is a fat like molecule that cannot dissolve in water, as a result fats are accumulated in clusters hence there is a difficulty in fat digestion.As it clumps together. It moves as droplets through the digestive system .By the time fat reaches the small intestine it has not been digested at all so the dietary fat in the small intestine looks like a fairly large globs of fat. These globs remain until the bile that is produced in the liver and stored in the gall bladder mixes with the large fat droplets.

Bile contains bile salts which acts as an emulsifier (breakdown of large fat droplets into smaller droplets) of lipids.

So the bile salts breakup and coat the fat in the small intestine to form much finer droplets these finer droplets have more surface area and this aids digestion because the fat digesting enzyme pancreatic lipase can only act on the surface of fat droplets. when the pancreatic lipase act on the lipid it breaks it down which results in free fatty acids and monoglycerides which are the two digestive products of lipids.

The absorption occurs within the epithelium cells and their transportation is done by fatty acids, and triglyceride.

Explanation:

Biodiversity refers to the variety of life, including the diversity within species, between species, and across ecosystems. The number of populations of a species plays a crucial role in maintaining genetic diversity and ecosystem function, with declines in populations leading to losses in biodiversity and ecosystem stability.

The relationship between biodiversity and the number of populations is quite significant. Biodiversity encompasses the variety of life at all levels, including the diversity within species (genetic diversity), between species (species diversity), and within ecosystems (ecosystem diversity). Populations, which represent groups of interbreeding individuals of the same species, are central to biodiversity as they maintain genetic diversity and contribute to the structure and function of ecosystems.

A single species can have multiple, genetically distinct populations, and it is these populations that often interact with one another and with populations of other species to form a community. The health and resilience of these communities, and thus the entire ecosystem, are closely tied to the strength and variability of its populations. Therefore, a decline in the number of populations can lead to a loss of biodiversity, reducing the provision of ecosystem services and potentially destabilizing the environment.

For example, population declines due to habitat destruction, pollution, or other human activities can lead to a decrease in species diversity, which in turn affects ecosystem function. Likewise, preserving a wide variety of populations can help ensure the stability and continuity of ecosystem services that are crucial for human survival, such as nutrient cycling, climate regulation, and food provision.
