The strains of bacteria of genus Pseudomonas show range of
effects on Lepidoptera sp. larvae, from harmful or lethal. The Pseudomonas
chlororaphis and Pseudomonas protegens, from strains of sub-clade 1, are proven
to be lethal to the Lepidoptera sp. larvae.
Answer:
Pfiesteria species generally found in estuaries, the population of which are needed to be controlled only when they becomes toxic. Presence of large of fish triggers toxicity in Pfiesteria.
Explanation:
Pfiesteria are known to be associated with fish kills as for example large fish kill in the seas of North Carolina. It also causes blooming of algae in enormous numbers thus make the water bodies, hostile for survival of fishes and other marine lives. It affects human too by release of toxins in air and water often resulting in respiratory problems, infections of gastrointestinal system, headaches and fatigue. In this type of grave circumstances, leading to outburst of population of Pfiesteria, there is an urgent need to control.
Answer:
When the females tend to form a solitary group, the adult males have an advantage of mating with females in different social groups thus enhancing on the productivity of the species.
Explanation:
When both the sexes of the species tend to make a group, the males and the females of the group have to mate with the members of that particular group and hence the males have restricted mating options which reduce the size of the herd. When the females have a separate social group, the males can mate with the members of different groups and raise the herd size in a short period of time. This helps in the increase in the population size and also helps in avoiding inbreeding depression which happens among small grouped animals.
Answer:
They have identical genes.

Biologists recognize five levels of cell organization. The lowest and simplest is the cellular level. Organisms here are either unicellular organisms, like protozoa, or colonial organisms. Colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. Next on the scale of complexity is the level occupied by tissue. A tissue is a group of similar cells that perform a similar activity. Tissues that are organized around a common function together make up an organ, the third level of complexity. The fourth level of organization is the system, formed by a group of organs that together perform a specific bodily process. The fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life.
