New, disease resistant trees are bringing back the splendor of what has been called one of the prettiest towns in New England.
You'll find the Guardian men noble but sometimes resistant to what's good for them.
Rivers of James Island, South Carolina, has resulted in the production of disease-resistant races.
- The method employed is to select, for seed purposes, plants which are resistant to the particular disease.
The substance is very resistant to the action of chemical reagents, to digestion, and possibly belongs to the glyco-proteids.
A plant or animal in perfect health is more resistant to parasitical invasion than one which is ill-nourished and weakly.
But in the derivant valley peneplains developed in the present cycle of denudation, and there are residual summits also; in the Connecticut Valley trap ridges, of which Mt Tom and Mt Holyoke are the best examples; at Mt Holyoke, lava necks; occasionally in the lowlands, ridges of resistant sandstone, like Deerfield Mountain near Northampton; in the Berkshire Valley, summits of resistant schists, like Greylock, the highest summit in the state.
They are the most resistant to unfavourable conditions of environment, and are able, by a process of parthenogenesis, to give rise to ordinary, indifferent forms again, which can repopulate the gnat.
The exposed strata are in large part resistant sandstones.
In certain parts of the plateau there are narrow anticlinal uplifts, an outlying effect of mountain-making compression; here a ridge rises if the exposed strata are resistant, as in Chestnut ridge of western Pennsylvania; but here a valley is excavated if the exposed strata are weak, as in Sequatchie Valley, a long narrow trough which cuts off a strip of the plateau from its greater body in Tennessee.
When the two lowlands are traced eastward they become confluent after the Niagara limestone has faded away in central New York, and the single lowland is continued under the name of Mohawk Valley, an east-west longitudinal depression that has been eroded on a belt of relatively weak strata between the resistant crystalline rocks of the Adirondacks on the north and the northern escarpment of the Appalachian plateau (Catskills-Helderbergs) on the south; forming a pathway of great historic and economic importance between the Atlantic seaports and the interior.
The dove of thought falls lifeless if the resistant atmosphere of " the given " be withdrawn (Critique of Pure Reason, ed.
The belts of non-resistant rock have been worn away, leaving longitudinal valleys separated by hard rock ridges.
Calmette and Fraser found that when small doses of snake venom, insufficient to cause death, are injected into an animal, temporary disturbance is produced; but after a few days the animal recovers, and a larger dose is then required to produce any symptoms. By gradually increasing the dose the animal becomes more and more resistant, until at last a dose fifty times as great as that which would at first have produced immediate death can be injected without doing the animal any harm.
In 1953, he developed a method to make strains of wheat highly resistant to a single form of rust.
And although rust was highly adaptive, by making ten or so different wheat varieties resistant to different forms of rust, Borlaug helped farmers reduce the risk of crop loss to a minimum.
