Answer:
The magnetic field is strongest at point C.
Explanation:
In a magnetic field, the center is known to be strongest region of the magnetic field while between the two poles outside the bar magnet are the weakest region.
Lines of the magnetic field are seen to be the densest even at the center of the magnetic field while between the poles outside the bar magnet, it is least dense.
A magnetic field is known to be a field which shows the magnetic impact and influence on electric charges, magnetic materials and electric currents.
Answer:
to adapt to dryland conditions
Explanation:
The main groups of land plants are vascular plants and they have developed diverse adaptations to survive on land, especially in climatic zones where drought and high temperatures are common. Some of the most important plant adaptations to land ecosystems include, among others, the development of a cuticle to prevent water loss, stomata capable of regulating water evaporation, desiccation-resistant spores coated in sporopollenium polymer, etc. Moreover, in seed plants, which are considered to be the most evolved vascular plants, the endosperm tissue produced inside the seeds is nourished by the parent sporophyte during the first stages of plant development.
It would be the start up of iron. Causing it to be a reactant and spread it across.
Answer:
The experiment should have more different subject groups, with each group consuming a different amount of beta carotene.
Explanation:
When designing an experiment, to determine the effect of the amount of a substance, the experimental design should be done to accommodate more than two experimental group with each group treated with different amount of the substance and also a control group. This will enable the researcher to determine the effect of the different ranges of amount.
In the example, in other to determine if vitamin A is dependent of the amount of beta carotene consumed, there should be more different subject groups, with each group consuming a different amount of beta carotene.
