Answer:
The amount Roberta makes an hour is $119.5
Explanation:
Let the number Roberta makes be x hours.
Amount earned in x hours shift - 9*x + 12.5% of the amount of jewelry sold.
Number of hours worked by Roberta if 9 hours and jewelry worth $380 is sold by her.
Substituting the values:
Amount earned in an 8 hour shift = 9*8 + 12.5% od 380
= 72 + 0.125 * 380 (12.5% = 0.125)
= 12 + 47.5
= 119.5
Wind has no effect on a plants respiration rate True
Where sugars are formed are referred to as the sink True
Both the xylem and phloem do not use any plant energy to translocation materials True
The amount of humidity in the air will affect transpiration True
The rate of transpiration reduces as the relative humidity of the air around the plant increases. Compared to more saturated air, dryer air makes it simpler for water to evaporate. A plant's transpiration rate will rise when air movement around it increases.
<h3>What about plants respiration?</h3>
- Water vapor is lost via the process of transpiration through a plant's stomata.
- When it's very hot outside, the plant loses water vapor to cool down, and water from the stem and roots flows up or is "drawn" into the leaves.
- In addition, plant transpiration contributes significantly to the leaf's energy balance by providing evaporative cooling.
- Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration.
- Plants use transpiration for a variety of purposes.
- The direct effects of transpiration include controlling the plant's temperature and supplying water for photosynthesis.
- Additionally, it facilitates the movement of glucose and nutrients through the plant's vascular tissues.
- Plants lose water through a process known as transpiration.
- A plant's roots can collect up to 99.5% of the water that the plant transpires, which is not used for growth or metabolism.
- For the surroundings to remain wet, transpiration is necessary.

Answer:
It is true
Explanation:
Use the DNA for the identification of suspects, it has been classified among secretors and non-secretors. In the category of secretors are individuals whose body fluids can be classified, through the determination of their blood group, with saliva being the most suitable substance.
Non-secretors can be classified but blood particles cannot be detected in the fluids.
Answer:
Option 3, of the abiotic factors found in their environment
Explanation:
The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.
The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case, if a bacteria lives in an environment where temperature is less than -5oC or higher than 50oC, then such habitats are considered to be “habitats with extremities” as special physiological mechanisms are required to maintain the homeostasis and survive.
Likewise absence of sunlight further adds to the extremities of the habitat.
Option 3, is correct
It’d be at least 70 million years.
