The photo shows a group of bacteria. Bacteria are single-celled microorganisms that can be found in various environments, including soil, water, and the human body. They can have different shapes and sizes, and some bacteria can cause diseases while others are beneficial. In the given photo, the organisms depicted appear to be small and unicellular, characteristic of bacteria.

The photo above shows a group of viruses. Viruses are microscopic infectious agents that can only replicate inside the cells of living organisms. They are not considered living organisms themselves as they lack cellular structure and cannot carry out metabolic processes. The photo likely shows a cluster of virus particles, which are often composed of genetic material (DNA or RNA) surrounded by a protein coat.

The correct answer is the reproduction of bacteria by asexual means. This is indicated by the presence of "a reprodução assexuada da bactéria" in the options. The figure likely depicts the process of asexual reproduction in bacteria, which can occur through binary fission, where a single bacterium divides into two identical daughter cells. This method of reproduction does not involve the fusion of gametes or the exchange of genetic material, resulting in offspring that are genetically identical to the parent.

The correct answer is "da letra c". This means that the correct sequence in ascending order is "Espécie - gênero - família".

The correct answer is "hematófogo" because the question is asking about the feeding habit of the blood-sucking bat, which classifies it as a hematophagous animal. Hematophagy refers to the act of feeding on blood, which is the primary diet of blood-sucking bats. Therefore, the correct answer is "hematófogo".

The correct answer is taxonomia. Taxonomia is the science of identifying and classifying living organisms based on their characteristics and relationships. It involves categorizing organisms into different groups and naming them according to a standardized system. This helps in organizing and understanding the vast diversity of life on Earth. Chromatologia is not a term related to the identification and classification of living organisms. Geologia is the study of the Earth's structure and history. Ornithologia is the study of birds. Numerologia is the belief in the mystical significance of numbers.

The correct answer is "assexuada." In asexual reproduction, offspring are produced without the involvement of gametes or the fusion of genetic material from two parents. This means that the offspring are genetically identical or very similar to the parent. This lack of genetic diversity is a characteristic of asexual reproduction.

The given answer "uma célula vegetal" is correct because the figure shows a cell with a cell wall, which is a characteristic feature of plant cells. Additionally, the presence of chloroplasts, which are responsible for photosynthesis, further supports the identification of the cell as a plant cell.

The correct answer is "carnívoro." This means that the animal in question is a carnivore, meaning it primarily eats meat. This suggests that the animal has adapted to a diet consisting mainly of other animals, indicating its predatory nature.

According to the taxonomy proposed by Linnaeus, "homínidas" refers to a family. In the Linnaean classification system, organisms are categorized into a hierarchical structure, with family being a higher rank than genus, order, and species. Therefore, "homínidas" being classified as a family means that it represents a broader group of organisms, including multiple genera and species within it.
