Answer:
C
Explanation:
its temperature because it's the best answer
The air diffuses into the capillaries surrounding the alveoli.
2. The pulmonary veins carry oxygenated blood to the heart.
3. Air enters the bronchioles in the lungs and reaches the alveoli.
4. The capillaries join together to reach the arteries, transferring the oxygen.
5. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.
6. The left atrium fills with oxygen-rich blood and contracts to fill the left ventricle.
Answer: Ecosystem
Explanation:the ecosystem is a network of organisms,their environment and their interaction in a particular place.it involves the interaction between the different organisms that make up a community and it's non-living environment.
The living organisms share resources with each other and include autotrophs, heterotrophs,decomposers; trees,grasses,insects, animals etc.
The non living components include rainfall,air water etc
Light, carbon dioxide, and water are the materials necessary for photosynthesis. Glucose (sugar), water, and oxygen are produced.
Answer:
Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.
