Rickets is a disease of growing bones. Consequently, it usually is seen in young, weaned, growing pigs in which there is a deficiency, an imbalance, or a failure of utilization of calcium, phosphorous or vitamin D. Rickets usually is caused by a dietary deficiency of vitamin D or phosphorus. And Osteoporosis a medical condition in which the bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D. More than 10 million Americans have osteoporosis, but most do not realize that they have it.
One of the big differences is one occurs mostly to pigs and the other effects adults.Another difference is one occurs while the bones are growing and the other happens after the bones are already grown. I hope this helps!!!
Answer:
A) NaCl will be exported from the red blood cells by facilitated diffusion.
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
Answer:
C
Explanation:
A rainforest is humid, therefore, water uptake would likely not be an issue. However, rainforests have a huge number of trees, often these are very tall. These large trees might block out the sun from the smaller plants nearer the ground. This means they would struggle to properly photosynthesise, as they wouldn't have the necessary light energy.
Therefore, as a survival adaptation, it is likely that an allele that produced broader leaves for photosynthesis would be selected for in this population. Broader leaves would give a larger surface area for the plant to absorb light energy to perform photosynthesis.
