Os baculovírus são vírus patogênicos a insetos, encontrados principalmente na ordem Lepidoptera. Como as larvas Anticarsia gemmatalis, é uma praga que causa sérios danos à cultura da soja na América Latina. Devido a sua ocorrência natural, os baculovírus são ótimos candidatos e já estão sendo usados em programas de manejo integrado de pragas, e sua inclusão natural em cristais proteicos permite a produção de biopesticidas com fácil tecnologia de aplicação e efetividade infectiva, representando economia e biossegurança em relação aos inseticidas químicos. Em diversos testes de segurança, foi estabelecido que o vírus é inofensivo a microrganismos, outros invertebrados (exceto alguns insetos), vertebrados e plantas, e persistem no meio ambiente, podendo causar epizootias, com morte de um grande número de larvas. Além disso, ao morrer, geralmente o inseto rompese facilmente, liberando grande quantidade de poliedros (vírus incluídos em cristais proteicos) no ambiente, servindo de inóculo para infectar populações subsequentes de larvas do inseto hospedeiro.

Considerando apenas a classificação científica da botânica para as estruturas ou componentes vegetais normalmente vendidos como alimentos, assinale a afirmação INCORRETA.
Sobre este assunto, é INCORRETO afirmar:
A composição de carboidratos no glicocálice de hemácias, mostrado no esquema abaixo, representam aglutinogênios (antígenos) que determinam os grupos sanguíneos do Sistema ABO. A síntese do antígeno H depende da presença de, pelo menos, um gene autossômico dominante H no genoma do indivíduo e é indispensável para a adição do antígeno A e/ou do antígeno B (como mostrado no esquema), pelos produtos dos genes I A e I B, respectivamente. Os indivíduos com alelo H e os alelos ii, ou os indivíduos desprovidos do gene H são identificados no grupo “O” pelas técnicas tradicionais de determinação de grupos sanguíneos ABO, mas os indivíduos (hh) são ditos Falsos “O”. Os alelos Hh apresentam segregação independente dos alelos I A IB i.
Sobre os fungos e suas associações, é INCORRETO afirmar:
Com base nas informações acima e em outros conhecimentos sobre o assunto, assinale a afirmação INCORRETA.
O esquema abaixo representa vários processos necessários para a produção do pigmento melanina pelos melanócitos, destacando algumas organelas celulares, moléculas e processos metabólicos.
A figura abaixo representa uma charge intitulada “Se as organelas pudessem falar”, produzida com base em funções e/ou características próprias de cada uma delas.
NÃO está correto o que se afirma em:

Renato está sempre desenhando e colorindo triângulos na seguinte ordem:
Qual o próximo triângulo que ele irá fazer?
O Tangram Clássico é um quebra-cabeças chinês formado por 7 peças: 2 triângulos grandes, 2 pequenos, 1 médio, 1 quadrado e 1 paralelogramo.
Com essas peças, podemos formar várias figuras, utilizando todas elas, sem sobrepô-las. Estima-se que é possível montar mais de 1700 figuras. Dentre as figuras abaixo, qual NÃO pode ser formada utilizando-se as peças do Tangram Clássico?
Sabe-se que a massa do Sol é de 1,989.1027t, Sabe-se que a massa do Sol é de 5,972.1021t e a massa da Lua é de 7,348.1019 t.
Aproximadamente, quantas vezes a massa da Terra é maior que a massa da Lua?

Importance of Aquaculture
Aquaculture involves the art, science and business of breeding aquatic animals and plants in fresh or
marine waters for human use. It also extends to the marketing of such organisms in a controlled environment. It is a kind of agriculture, and therefore, it requires inputs such as clean water and nutrients.
It also requires storage for harvested produce, transportation and marketing facilities.
Inputs often depend on the species that are farmed. Species lower on the aquatic food chain usually require less input, as they feed on microorganisms and are fine in just clean water. More inputs like fish or fishmeal, cereals, or grains are required, as we get higher on the food chain with species like salmon or tuna.
All over the world, the demand for seafood has increased because people have learned that seafood as part of regular diets are healthier and help fight cardiovascular disease, cancer, Alzheimer’s and many other major illnesses.
Aquaculture will add to wild seafood, and make it _______ and accessible to all.
Aquaculture business provides tax and royalty revenue to local governments. Besides, there is also potential revenue from exports.
