Water pressure in stems and leaves helps to

Maksim231197 [3]

Answer:

When the soil of a plant runs too low of available water, the water chains in the xylem become thinner and thinner due to less water. Effectively, the plant is losing water faster than it is absorbing it. When this happens, the plant loses its turgidity and begins to wilt.

maks197457 [2]

Answer:

Option 5, Peracetic acid

Explanation:

Options

Chlorine
Copper sulphate
UV radiation
Ozone
Peracetic acid

Solution

Peracetic acid is used as a cleanser and disinfectant in food industry and not in water and wastewater treatment plants.

Chlorine is one of the commonly used disinfectants across the globe and one of the benefits of chlorine is that it also has residual disinfectant properties. UV however stronger than chlorine as disinfectant does not have residual disinfectant properties. Copper sulphate is a disinfectant used to kill fungi and algae and ozone is used to kill bacteria and viruses.

Hence, option 5 is correct

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other

Sholpan [36]

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

<h3>What is plasma?</h3>

It is an aqueous solution that is thick in consistency, straw-colored, and somewhat alkaline. Fifty five percent of the blood is formed by it.

It is made up of a variety of organic and inorganic components, including 90–92% water and 6–8% solutes.

It includes fibrinogen, globulins, albumins, a trace quantity of sodium, calcium, magnesium, chloride, bicarbonate, glucose, amino acids, lipids, and other coagulation-related substances.

Plasma's primary function is to transport proteins, hormones, and nutrients to the body's many organs. Additionally, plasma is where cells dump their waste. The plasma then aids in the body's elimination of this waste. All components of the blood are also transported through your circulatory system by blood plasma.

Describe evidence from biogeography that species evolve adaptations to their environment

Romashka [77]

Answer:

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.
