Microbeads are tiny, smooth, plastic spheres found in common household products such as facial soap. These beads, measuring from 0.0004 to 1.24 mm, roughly the size of some fish eggs, are too small to be removed by water treatment systems. Thus, they end up in rivers, lakes, and other bodies of water. The accumulation of these microbeads is an environmental concern for aquatic biologists because microbeads
(1) make the lakes and rivers cloudy and dirty, affecting their appearance
(2) may stick to some household water pipes, preventing drainage problems
(3) could be mistaken for food by some species, working their way up the food chain
(4) could clog fishing nets, affecting the ability of fishermen to catch fish

Answers

Answer 1

Answer:

(3) could be mistaken for food by some species, working their way up the food chain

Explanation:

Microbeads, such as other microplastics, can affect wildlife in many ways, but mostly by

IngestionIntroduction and transference in the trophic webInteraction with other contaminantsMicroinvertebrates, bacteria, and viruses colonize these microplastics and can be transported long distances.

Organisms like mollusks, crustaceans, fishes, birds, turtles, among many others, might confuse these elements with food and eat them. Microbeads might float or accumulate in sediments and be ingested by different benthonic species. The ingestion of microbeads by inferior links in the trophic web means a direct entrance in the trophic web where many superior links are affected too while feeding with already contaminated prey.

The ingestion of microbeads can cause a significant impact on the growth, development, and reproduction of freshwater and seawater species.  

Microbeads, like other microplastics, characterize for their durability in time and resistance, which means that the ones that are already in the oceans and rivers will last there for centuries.

When and where would you expect to find the highest rate of primary productivity

Answers

Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.

Explanation:

I explained on the top-

The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.  

• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.  

• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.  

• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.  

• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.  

• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.  

These environments are mainly critical for the sustenance of global biological productivity.

Explanation:

Olá. Primeiramente é necessário informar que perguntas em português devem ser postadas no campo "world Languagens". Isso porque esse não é o servidor basileiro e sim o servidor americano. Caso contrario, a sua pergunta pode nunca ser respondida e até mesmo excluida do site.

Em segundo lugar, para que seja possivel que você repsonda a essa pergunta você precisará preencher um Quadrado de Punnett, como mostra a figura abaixo.

Como você sabe, as mulheres possuem os cromossomos XX e os homens XY. Como a mulher apresentada na pergunta acima possui o alelo para o daltonismo, mas não apresenta daltonismo, podemos considerar que apenas um dos cromossomos dela possuem esse alelo. O alelo para o daltonismo é recessivo, sendo assim, podemos considerar que essa mulher possui os alelos XDXd. Homem com quem essa mulher se casa, não possui daltonismo, logo os alelos dele são XDY, como mostrado na figura.

Ao preencher o quadrado de Punnett, você verá que existe a possibilidade desse casal possuir duas filhas, uma delas pode possuir os alelos XDXd, igual a mãe e, portanto, ser carreadora do alelo para o daltonismo.

Sendo existe uma chance, em duas filhas desse casal ter uma filha carreadora de daltonismo. Isso é igual a 1/2, que resulta em 0,5, ou 50% de chances de ter uma filha carreadora de daltonismo.

A population of ground mice consist of 500 individuals. You are interested in the gene that codes for for a color and find out there are 580 dominant alleles in this population. What is the allele frequency for the dominant allele? What is the allele frequency for the recessive allele? (show your work)

Answers

Answer:

0,58

Explanation:

Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given locus/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic locus, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).

Anthropologist: In an experiment, two groups of undergraduates were taught how to create one of the types of stone tools that the Neanderthals made in prehistoric times. One group was taught using both demonstrations and elaborate verbal explanations, whereas the other group learned by silent example alone. The two groups showed a significant difference neither in the speed with which they acquired the toolmaking skills nor in the level of proficiency they reached. This shows that Neanderthals could just as well have created their sophisticated tools even if they had no language
Which one of the following, if true, most weakens the anthropologist's argument?
(A) Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.
(B) The students who were taught with verbal explanations were allowed to discuss the toolmaking techniques among themselves, whereas the students who learned by silent example were not.
(C) The tools that the undergraduates were taught to make were much simpler and easier to make than most types of tools created by Neanderthals.
(D) The instructor who taught the group of students who learned by silent example alone was much less proficient at making the stone tools than was the instructor who taught the other group of students.
(E) The tools created by Neanderthals were much less sophisticated than the tools created by anatomically modem humans who almost certainly possessed language and lived at the same time as the Neanderthals.

Answers

Answer:

A

Explanation:

The point of this arguement is that with or without speaking they were able to make the same sophisticated and complex tools, if it is true that both had a language that would mean the silent people would have no point and that both types of humans had the same initial factors.

Air moves in a direction that creates land breezes.
Air above land warms faster than air above water.
Air blows over long distances in a continual straight path.
Air pressure remains the same while cycling over land and water.

Answers

The best answer would be:

The first option.

Air moves in a direction that creates land breezes.

If you'd like to know more about this, you can read on:

The arrows show how air moves as land breezes are created. In coastal areas, land cools much faster than water, so what happens is the air above it gets cooled down. When this happens, it becomes more dense moves downwards towards land. This causes high pressure and cause winds to blow outwards towards water (ocean).  

Air moves in a direction that creates land breezes. Therefore, option (A) is correct.

What is land breeze?

A land breeze is a type of wind that occurs at night and flows from land towards the nearby body of water, such as a lake or ocean. It is the result of temperature differences between the land and water surfaces during the nighttime hours. Land breezes are typically observed in coastal regions or areas near large bodies of water.

During the day, the land surface heats up more quickly than the water surface. As a result, the air above the land becomes warmer and rises, creating a region of low pressure. Meanwhile, the water retains its temperature more effectively, leading to a cooler air mass above the water and a region of high pressure. This temperature contrast sets the stage for the development of a land breeze.

As the sun sets and the land cools down faster than the water, the pressure gradient reverses. The air over the land becomes cooler and denser, forming a high-pressure area. Simultaneously, the warmer air over the water creates a low-pressure area. The pressure difference drives the wind to flow from the land towards the water, resulting in a land breeze.

Land breezes are typically characterized by gentle and steady winds blowing from the land towards the water. They are often observed during clear and calm nights when the temperature contrast between the land and water surfaces is significant. Land breezes can have localized effects, such as influencing local weather patterns and affecting coastal ecosystems.
