The best answer is B.
Each year many tundra plants retain their dead leaves rather than shed them. The dead leaves insulate fragile new buds from the wind and cold. Grass tussocks are a good example of this.
Many tundra plants also wear adaptive coats which are furry and waxy coatings on their leaves and stems. Fine hair or fuzz slows the wind, thus reducing drying and preserving heat.
The waxy coating of many plants also help reduce water loss and evaporative cooling by the wind
I know its not d but it might be c or a
Answer:
The correct answer is 0.26 M
Explanation:
The initial concentration of NaCl solution (Ci) is 5.0 M. The initial volume of the solution (Vi) is 13 mL. The final volume is the addition of 240 mL to 13 mL (Vf= 13 mL + 240 mL= 253 mL).
In order to calculate the final concentration of the solution (Cf) we can use the following expression:
Ci x Vi= Cf x Vf
This mathematical expression is often used to calculate concentrations in dilution procedures. So, we introduce Ci, Vi an Vf in the expression and we calculate Cf:
Cf= (Ci x Vi)/Vf= (5.0 M x 13 mL)/253 mL= 0.257 M ≅ 0.26 M

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p
That is called an insertion mutation which is a type of a frameshift mutation
depending on where you put the extra nucleotide, the amino acid sequence may look different.
