Resposta:
Ecotoxicologia
Explicação:
A ecotoxicologia é o estudo das interações que os seres vivos possuem não só entre si, mas também com o ambiente em que esses seres vivem.
Estudos de ecotoxicologia buscam compreender os diferentes tipos de reações causadas por substâncias químicas, bioquímicas e os processos biológicos que podem ocasionar essas reações, considerando a sensibilidade que diferentes organismos possuem a essas substâncias e os potenciais toxicológicos delas.

Answer:
Phylogeny: It is related to evolution dealings in the evolutionary development of a species. It is represented by different ways vertical or slanted.
Phylogenesis: It refers to the evolutionary relationships among species.
Phylogenetics: It is determination or estimation of evolutionary relationships among groups of species, organisms and genes.
Phylogenetics is a field of biology which is used to find relationships among different organisms. This relationship is showing through a tree (used to model actual evolutionary relationship of organisms). Ancestral divided into two descendant species because closely related organisms are shown in near branches. If there is too much divergence between two species its mean they are not closely related.
The history of speciation (one species becomes divided into more than one new species) tells us how these species are related to each other. If they evolve to be separate species relatively recently then they are "closely relative" similarly if they evolve to be separate specie long above then they are "distant relatives". For example orthologs are genes in different species that evolved from common ancestor gene by speciation; they retain same function in the course of evolution.
Explanation:
Si.
there is growing evidence that mitochondrial complexes i, ii, iii, and iv are part of a larger supercomplex. the advantage of having all four complexes within a supercomplex is that it makes the electron transport across various complexes easier and faster.
Mitchondria have four types of complexes-
Complex I- NADH/ ubiquinone oxireductase, blue
Complex II- Succinate dehydrogenase, pink
Complex III- Cytochrome c reductase
Complex IV- Cytochrome c oxidase
The electron flows through the various complexes in process of formation of the ATP molecules.
The advantage of having a supercomplex which accomodates all the four types of complexes is that the electron will then flow in solid state which is kinetically more favorable.

Answer:
A. True
Explanation:
Allolactose is an example of an inducer, a small molecule that triggers expression of a gene or operon. The lac operon is considered an inducible operon because it is usually turned off (repressed), but can be turned on in the presence of the inducer allolactose.
