In molecular biology, a vector is a DNA molecule that is used as a vehicle to transfer foreign genetic material into another cell.
The four major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes.A vector is a living organism that spreads infectious agents from infected animal to infected animal. Arthropod vectors include mosquitoes, ticks, flies, fleas, and lice. The haematophagous arthropod definition, which defines vectors solely as blood-feeding arthropods such as mosquitoes, ticks, sandflies, tsetse flies, and biting midges, is similar. Vector quantities include displacement, acceleration, force, momentum, weight, the speed of light, a gravitational field, current, and so on.

Answer:
plants need protein for healthy growth and development. One of the critical roles of protein in plants is regulating phototropism and mediating the response of plants to light-dark cycles. Proteins are also involved in energy-generating reactions, intracellular structure and membrane transport.
Explanation:
The answer is Atlantic Ocean ; Pacific Ocean.
A continental divide is a divide that separates continent’s watersheds. A continent may have more than two watersheds. For example North America has five continental divides. But United States is divided into two very large watersheds, one which drains into the Atlantic Ocean and the other into the Pacific Ocean.
Answer:
Large number of species and abundant resources.
Explanation:
Large number of species and abundant resources are the two characteristics shared by ecosystems that have high biodiversity. Habitat loss and pollution are the two specific human activities that result in a loss of biodiversity. Habitat loss occur when the human removed all the trees and vegetation in order to made the land for cultivation of crops or building houses. Pollution is the main cause that leads to loss of biodiversity. Human activities release gases which pollute the environment and leads to loss of biodiversity. Avoid activities that causes pollution and used of barren lands for cultivation and infrastructure. Climate change is naturally occurring factor that could lead to a loss of biodiversity. Biodiversity boosts ecosystem productivity and natural sustainability.
