6. In general, as both the force and velocity of impact increase, what happens to the diameter of
the resulting blood droplets?

Answers

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

In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the b hemoglobin alleles in the human gene pool. In the United States, the parasite that causes malaria is not present, but African-Americans whose ancestors were from equatorial Africa are present. What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa

Answers

Answer:

directional selection, stabilizing selection

Explanation:

Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.

hydrogen ions and bicarbonate ions?

Answers

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.

What is a chemical reaction?

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

Equation B represents the formation of the acid as hydrogen ions are released along the product. The proton donation (hydrogen ion) is the characteristic property of the acids.

There are 2 oxygen atoms in equation A, and 3 atoms of oxygen in equation B.

There are 4 hydrogen atoms in equation A and 2 atoms of hydrogen in equation B.

In equation B, carbonic acid breaks to form hydrogen ions and bicarbonate ions as:

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.

Answers

Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.

When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.

Biomass change from lower to higher trophic levels by decreasing.

The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.

There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.

It should be noted that global warming brings about the increase in the temperature around the world.

What is Sporobolus ioclados?

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

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. This behavior does not kill the flower. In a particular environment, bees with short tongues replace bees with long tongues. Predict the effect on the proportion of plants with deep flowers in future generations. Justify your prediction.

Answers

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:

Bees with long tongues can obtain nectar from deep flowers by visiting the top of them and extending their tongues to their bottom.During their visit to the flowers and their search for nectar, long-tongued bees transport pollen from flower to flower, favoring pollination.Bees with short tongues can obtain nectar from deep flowers by drilling holes in their base without visiting their tops.Short-tongued bees do not need to access the nectar by the top of the flower. They do not get in contact with stamens, so they do not play a pollinator roll. In a particular environment, bees with short tongues replace bees with long tongues.

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.

What do you mean by environment?

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.

A geneticist crossed pure breeding black mice with pure breeding brown mice. All the mice in the F1 generation had black coats. When these mice were crossed, they yielded 961 black coated mice and 317 brown coated mice.

Fill in the new combinations of alleles in the F2 generation.

Answers

Answer:

The correct answer is - the brown allele is not independent from the black allele and disappears in the F1 generation.

Explanation:

IN this question it is given that there is a cross between pure black and pure brown breed and the F1 generation has all-black coat offspring and their self cross produced 961 black and 317 brown.

The black coat offspring is three times than the brown coat offspring in F2 generation which means they have 3:1 ratio that comes in the self cross of heterozygous only there for the F1 generation black coat offspring have the heterozygous genotype for the trait,

Thus, the brown allele is not independent of the black allele and disappears in the F1 generation.

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral elm species without winged-seeds

Answers

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.
