Answer:
Explanation:  Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.
 
        
             
        
        
        
According to productivity expert Odette Pollar, "to do more in a day, you must do less, not do everything faster." Pollar said that on the average if you spend not enough time and energy on those things you alone can do, you must look for tasks that others can and let them take over. Focus on the prize.<span>

Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb. 
3) The punnet square for cross between these parents can be shown as follows:
         B           b
B     BB       Bb
B     BB       Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).

B. The area's climate 
Specific plants need specific climate conditions in order to survive. The other answer choices have little to no impact on the growth of plants.
