Ao estudar para o vestibular, um candidato percebeu que ainda tinha dúvidas em relação aos processos de difusão simples, transpo

rte passivo facilitado e transporte ativo através da membrana plasmática e pediu ajuda para outro vestibulando. Este utilizou a figura abaixo para explicar os processos. Para testar se o colega havia compreendido, indicou os processos como A, B e C e solicitou a ele que os associasse a três exemplos. Os exemplos foram: (1) transporte iônico nas células nervosas; (2) passagem de oxigênio pelas brânquias de um peixe; (3) passagem de glicose para o interior das células do corpo humano.
a.
Indique as associações que o candidato deve ter feito corretamente. Explique em que cada um dos processos difere em relação aos outros.


b.
Em seguida, o candidato perguntou por que a alface que sobrou do almoço, e tinha sido temperada com sal, tinha murchado tão rapidamente. Que explicação correta o colega apresentou?

Answer:

O sal tem uma grande capacidade de absorver água do ambiente.

Explanation:

A passagem de oxigênio pelas guelras de um peixe é um exemplo de difusão porque a difusão ocorre quando a concentração de uma substância é maior em uma região e menor em outra região, de modo que as partículas se movem da região superior para a região inferior. A glicose entra na célula por meio do processo de transporte passivo facilitado porque passa por uma membrana semipermeável por uma proteína específica. O transporte iônico nas células nervosas é o exemplo do transporte ativo porque se move pelo uso da energia contra o gradiente.

O sal tem uma forte capacidade de absorver água do seu entorno, então quando a alface temperada com sal, o sal absorve a água presente no interior da alface, portanto a retirada da água é a retirada da água é a causa do murchamento.

Which of the following explains how fault is formed?
lord [1]

Answer:

a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.

Explanation:

The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.

Reason -

A fault is a fracture or zone of fractures between two blocks of rock.

Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.

During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.

The fault surface can be horizontal or vertical or some arbitrary angle in between.

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells
UkoKoshka [18]

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.

<h3>What is keratinocytes?</h3>
  • Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
  • Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
  • They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
  • The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
  • A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
  • The skin's epidermis is made up of this kind of epithelium.

Some protists can reproduce both sexually and asexually. What's a major advantage of each?
Neporo4naja [7]

Answer:

(A). Sexual reproduction increases genetic diversity, and asexual reproduction can be more rapid.

Explanation:

Sexual reproduction is a mode of reproduction, which involves formation of new organisms by combination of genetic information from two organisms of different sexes. The major advantage of sexual reproduction is to develop genetic diversity as new organism is produced by mixing up genetic material of both the parents.

On the other hand, asexual reproduction involves formation of new organisms from a single parent having identical genetic makeup as present in parent cell.  One of the major advantage of asexual reproduction is to produce high number of offspring in less time as it is more rapid than sexual reproduction.

Thus, the correct answer is option (A).
