Answer:
Avirulent.
Explanation:
VIRULENCE is the ability of a pathogenic organism to infects the host, leading to damages or death of the host. The extent of these virulent effect depends on certain chemical substances ( called Virulence factors) produced during the pathogenic processes.
The virulence effects is achieved due to the ability of the virulent factor to disrupt the entire physiological mechanisms of the organisms; e,g crop plants; though suppression of the host immune response, disruptions of the immune mechanisms, colonization of the host DNA structure etc. Therefore the pathogenic effects suppressed the host resistance and spread throughout the host body system.
In this present scenario, the pathogenic effect of the likable bacteria; is not virulent, because
none of the d crop pant is completely diseased.
the nascent intenodes and leaves are growing to usual size.
Consequently, the physiological and the morphological features of the crop plants are still intact. Thus the infection is AVIRULENT.
Answer:
The Pacific Plate is colliding with the Australian Plate at a rate of about 40 mm/yr. The East coast of the North Island is being compressed and lifted by this collision, producing the North Island and Marlborough Fault Systems.
Explanation:
Answer:
Darwin's greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin's discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science
Answer:
Practice that provides the best means of protecting biodiversity in the wild for future generations is - <u>expanding breeding programs for endangered species .</u>
Explanation: The best way of preserving biodiversity for future generations in the wild -
- <u>Expanding breeding programs for endangered species . -:</u> Breeding programmes, such as the panda, help conserve endangered species. Replanting hedgerows because there is greater biodiversity in them than the fields they surround, minimizing deforestation and the release of greenhouse gases, protecting and creating new endangered ecosystems, often by making National Parks.
The other statements are not so suitable means of protecting biodiversity in the wild for future generation as the first statement indicates about the initiation of recycling programmes in neighborhood , which has no role in preservation of biodiversity or wildlife because the statement is about keeping the environment clean and healthy .
The other statement is about reduction of air pollution as buying vehicles with reduced carbon emissions improves the quality of air.
And the other statement of Protecting wildlife areas such as national parks comes under the other statement which states "expanding breeding programs for endangered species".
Hence , the correct option is D.
True! If any one of the two elements changes then the velocity changes.
