C. They unwinds the two strand of DNA.
Answer:
A species that is not native to a particular region is called an <u>invasive species. </u>
Explanation:
In ecology, invasive species can be described as species which are introduced into an environment. These species are not native to the environment.
Introduction of invasive species in an environment can destroy a stable ecosystem. The invasive species will compete for resources like food, shelter, water etc. They might cause the extinction of the species on which they start feeding. They might fight with predators feeding on the same prey.
From an agronomical point of view, there is a lot that the grower can do to maximize sugarcane yield. Proper crop nutrition is an important factor to achieve this.
In a large number of cases, nutrients that drive sugarcane yield forward, will also improve the sugar content and quality of the harvested sugarcane crop.
Most required nutrients have specific roles to play in improving yield:
Answer:
plants are the things that gives oxygen to breathe
they function through the energy given by the the sun and the minerals from the roots
Explanation:
Answer:
D
Explanation:
Osmosis is a biological phenomenon whereby the molecules of a solvent moves through a selective permeable membrane from an area of low solute concentration to an area of high solute concentration.
There are three types of osmotic solutions viz;
Isotonic; which has an equal solute concentration
Hypotonic; which has a lower solute concentration
Hypertonic; which has a higher solute concentration
When a living cell is placed in a solution, the solvent molecule (which is usually water) moves in or out of the cell depending on whether the cell has a higher solute concentration (hypertonic) or lower solute concentration (hypotonic) in comparison with the solution it was immersed in.
A good example can be observed in the absorption of water by the root hairs of plants; root hairs, due to the accumulation of minerals, possess a lesser concentration of water molecules than the soil i.e the root hairs are hypertonic. Due to this osmotic gradient, water (solvent) moves from the SOIL, which has a lower concentration of solute, to the ROOT, which has a higher concentration of solute.
