Answer: depending on viscosity, mass and velocity of impact, if droplet integrity is maintained, as velocity increases, diameter will increase from

Approximately d*sqrt(2) to 2*sqrt(d^3/6a) where d is original diameter and a is thickness when the droplet flattens into a disc.

Explanation:

This applies generally to any liquid droplet, which by inference falls and impacts a solid surface. The impact force is mgh where m= mass, g= acceleration due to gravity, h= initial height.

A liquid droplet deforms on impact. Assume the drop is sperical, then the deformation distance, d= diameter of the droplet then the average impact force = mgh/d.

The droplet may spread, splash or bounce, depending on viscosity and force, which depends on mass and velocity immediately before impact.

All than can be said is that if the droplet maintains integrity it could achieve the shape of half a highly flattened oblate spheroid. Approximating this with a flattened disc of thickness a, and an original volume of 4/3pi(d/2)^3, the volume as a disc =a*pi*r^2 so the horizontal diameter = 2*sqrt(d^3/6a)

It is not really possible from the available data to determine whether the droplet would remain its integrity, but at sufficiently low force/velocity, the droplet could retain a near-hemispherical shape, giving a horizontal diameter of the hemisphere = d*sqrt(2)

As velocity increases, if integrity is maintained, the diameter will increase from the second approximation to the first

Answer:

The proportion of plants with deep flowers in future generations will decrease and will be very low.

Explanation:

To analyze this, we need to keep in mind the pollination process and the following general ideas:

In this particular environment, long-tongued bees used to visit plants with deep flowers to get their nectar. They used to get in contact with mature stamens and carry the pollen on their bodies to the next flower. During this process, long-tongued bees were able to ensure pollination and helped to keep a high reproductive rate of plants with deep flowers.

When shorted-tongue bees arrived at this environment, they were able to replace long-tongued bees. They also looked for the nectar of deep flowers, but instead of visiting them from the top, they were adapted to obtain nectar by drilling holes in the flower base. In this way, they missed the contact with mature stamens and pollen.

Long-tongued bees disappear, and short-tongued bees did not play a role in the pollination process of deep flowers, then the reproductive rate of these vegetable species probably started to decline.

Probably, with time, the proportion of plants with deep flowers in an environment dominated by short-tongued bees will be very low.

The proportion of plants with deep flowers in future generations will decline if bees with short tongues replace bees with long tongues.

Anything which is present in the surrounding of an organism is called its environment. It may consist of Biotic and abiotic factors.

Bees with short tongues are able to obtain nectar from deep flowers by drilling holes in the base of the flower without visiting the top of the flower. In this way, such bees are not in contact with mature stamen and pollen. Therefore, they will not play an effective role in pollination. And if such bees are replaced with long tongues bees, there will never be a deep flower obtained. Deep flowers are obtained by long-tongued bees because they take nectar from the top side and with it they also take mature stamen and pollen to perform successful pollination.

Therefore, the proportion of plants with deep flowers in future generations will decline, if bees with short tongues replace bees with long tongues.

The more an animals color matches their surroundings, the more likely it is for survival. White rabbits fur matches the snow, and brown rabbits fur blend with the dirt

Explanation:

The colors that stand escape the many would be red and blue and the one's camouflage is mostly brown, green, and yellow, swinging on its place and surroundings.

The prey that is more delicate in color lasts extended. As the duration goes on, the white prey lasts extended than the blue colors as they blend into their surroundings sufficiently.

The green, red, and orange varied practically extinct over the 3 generations because they could be stained easier and could not blend into their surroundings.

The colors were very necessary for how it influenced the people because the more brilliant the color the more predators it's going to seduce and the colors such as green and brown are more camouflage.

The more an animal's color approximates its surroundings, the more possible it is to survive. White rabbit's fur approximates the snow and brown rabbits' fur in combination with the dirt.

Explanation:

The animals that are the main consumers of the Pan dropseed are all animals have complex organ systems. Especially Seed-eating birds including American sparrows, and elephants.

The grass family contains a nearly universal genus of plants called Sporobolus. The genus' members are frequently referred to as dropseeds or sacaton grasses.

They grow in numerous sorts of open habitat in warmer temperatures and are typical grassland and savanna plants. At least one species, as well as another, are endangered.

Only alkali sacaton has the little moth Bucculatrix sporobolella's caterpillar been discovered (Sporobolus airoides).

On Laysan Island, it appears that the local elimination of S. virginicus by feral rabbits led to the extinction of the Laysan dropseed noctuid moth (Hypena laysanensis).

All of the animals that eat the Pan dropseed most frequently have intricate organ systems, including seed-eating birds including American sparrows, and elephants

Thus, these are the animals that are the main consumers of the Pan dropseed.

The correct answer is  a. absent spinal reflexes below the level of injury.

Explanation:

Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.

Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B

Explanation: A has H2O (water). B has a hydrogen ion, so acidic.

In B H2CO3 is carbonic acid

The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.

Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:

2H₂ + O₂ → 2H₂O

H₂CO₃ → H⁺ + HCO₃

Here, carbonic acid dissociates a proton that makes the solution acidic.

Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

Answer:

In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species

Explanation:

A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.
