Answer:

the process of turning from liquid into vapour

Answer:

Evaporation is a surface phenomenon, which implies that the process only occurs at the surface of the liquid. During evaporation, the molecules of the liquid that are present at its surface overcome the intermolecular forces of attraction to break away from the liquid and escape into the atmosphere as a gas (or vapour).

Four common relationships between organisms are listed in the box. Which statements best describe these relationships?

A. Relationships 1 and 4 are examples of mutualism. Relationship 2 is an example of commensalism. Relationship 3 is an example of parasitism.
B. Relationships 1, 2, and 4 are examples of mutualism. Relationship 3 is an example of parasitism.
C. Relationship 1 is an example of commensalism. Relationships 2 and 4 are examples of mutualism. Relationship 3 is an example of predation.
D. Relationships 1 and 2 are examples of commensalism. Relationships 3 and 4 are examples of mutualism.
Please explain, I don't want just an answer.

Answers

The correct answer is option B

Species interactions are categorized based on their reciprocal effects (the effects that the interaction has on each species/individual involved).

1. Bees pollinate plants as they move from flower to flower collecting pollen.

This is a mutualistic relationship because the both species involved in this interaction benefit from the interaction. The bee benefits because it obtains nectar which is provided by the plant. The plant benefits because the bee carries the plants pollen to other plants, allowing the plant to reproduce.

2. Green algae grow on the backs of spider crabs living in shallow water.

This is another example of a mutualistic relationship because both species involved in this interaction benefit from the interaction. The spider crab benefits from the camouflage that the algal growth provides, while the algae benefits from the protection from predators provided by the spider crab.

3. Fleas living on skin of dogs and obtaining nutrients from dogs blood.

This is a parasitic relationship because one of the species benefits from the interaction while the other species in negatively impacted by the interaction. The flea benefits from the nutrients obtained from the dogs blood while the dog is negatively impacted by the fleas presence (loss of blood, discomfort).

4. Nitrogen-fixing bacteria obtain nutrients from host plants and use the nitrogen to supply host plants with nitrogen.

This is an example of mutualism because both species in this interaction are benefitting from the interaction. The nitrogen fixing bacteria benefit by receiving nutrients from the host plant while the host plant is benefitting from receiving nitrogen from the bacteria.

Which scientists do you think had they biggest impact on the discovery of DNA and why

Answers

Answer:

He was paving the way for a discovery that would change the world. Scientists James Watson and Francis Crick were famously the first to work out the structure of DNA, and Rosalind Franklin and Maurice Wilkins are often credited for capturing the images of the molecule that made this possible.

Answer:

I believe that James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin made the biggest impact on the discovery of DNA.

Explanation:

At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. These 4 people worked together and made a significant discovery.

Which of these statements about ocean water is always correct?

a.) Its area is less than the area of freshwater.
b.)Its salinity is less than the salinity of freshwater.
c.) Its density is greater than the density of freshwater.
d.)Its temperature is greater than the temperature of freshwater.

Answers

Answer:

c.) Its density is greater than the density of freshwater.

Explanation:

Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.

The freezing point of seawater decreases as salt concentration increases.

Answer:

C.) Its density is greater than the density of freshwater.

Explanation:

Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases.

How are meiosis and mitosis different?

Answer: Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

. Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

From the California condor to the snowy owl, few birds compare to the tigers of the air: the great hunters whose beauty and skill have inspired art and literature for centuries. The most glorious feathers of the peacock or the vibrant plumage of a bunting cannot compete with the power of a peregrine falcon or the determination of an osprey. Included in this group of hunters, however, is one bird of prey that is little known but equally impressive. The kites of the world are generally smaller than most raptors, but just as astonishing in skill and grace as any other hunter of the skies.Most people think of paper or cloth structures flown with string from the ground when the word 'kite' is used. In addition to these popular toys, kite can also refer to a type of raptor. Kites have a small head, a short beak and long narrow wings and tail. Kites can be found all over the world in mostly warm regions. Kites live on a variety of preyfrom insects to small rodents or reptiles. Some kites eat only one kind of prey. Kites are generally masterful in the air and represent a group of birds that are among the most acrobatic of fliers.Two of the most familiar kites in the Southern United States are the swallow-tailed kite and the Mississippi kite. The Mississippi kite is rather plain to look at: a light brown and gray body with a buff or white colored head. But to watch a Mississippi kite fly is to watch a ballet in the air. These raptors eat primarily flying insects, so they do most of their hunting on the wing. As you might imagine, catching flying insects requires a great deal of agility and speed. If you are lucky enough to see one in flight, you will be amazed at the quick turns, graceful moves, and speedy pursuits of this bird. Look for them above large fields, especially during the summer.The swallow-tailed kite, also common in the South, is more easily identifiable and often seen flying over roads. With black wings and tail, white head and body, and a forked or swallow-like tail, this raptor is just as acrobatic as the Mississippi kite. Swallow-tailed kites like flying over highways in the summer as they can take advantage of the thermals, or columns of warmed air, that rise above the pavement. Once they have climbed to sufficient height, swallow-tails will glide, looking for snakes and reptiles and insects. They also eat small rodents, frogs, and other birds on occasion. Watching a swallow-tail fly is a lot like watching a gymnast perform a floor routine. Rarely flapping its wings, it uses its forked tail to make sharp turns, trace circles in the sky, or simply maintain a heading. Skilled, accomplished, and graceful, this bird is as entertaining as it is beautiful.Both kites are known to eat while flying, unlike most other birds of prey. This practice conserves energy and allows them to hunt almost continuously. While these kites are not listed as endangered, they are rare and in some states are listed as critical. Loss of habitat is the main reason for the decline. If you are lucky enough to see one, count yourself among the few. These magnificent birds are a sight you won't soon forget.How does the author develop the idea that kites are skillful fliers? Use details and quotations from the text to support your answer.
