Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
Baby girls are 4.1mm
Baby boys a 3mm
Explain that water moves down a water potential gradient, and the salt solution has a lower water potential than the vacuole so water leaves the vacuole through osmosis
In exam Q's key points are:
- Water potential gradient
- Higher water potential in vacuole
- Leaves through osmosis
<span>The main difference between adaptice radiation and other forms of speciationn is : Adaptive radiation happens over a relatively short time.
In natural process of speciation, the perfect mutation could occur within millions of years. In adaptive radiation, the mutation could instantly happenes not long after the radiataion process</span>
Answer:
Explanation:
Scientific theory: a well established, highly reliable explanation
Scientific hypothesis: makes predictions of future events/
Both: based on observations of natural phenomenons/ can be tested by many researchers
