Characteristics should be in the blank
The correct answer is:
Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.
Explanation:
Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
Answer:
The correct answer is - C. Multiply 500 by 1.5.
Explanation:
Given:
Force to move a desk = 500 N
weight of desk = 300 N
displacement = 1.5 meters
work done by Tine = ?
Formula:
work done (W) = F*d
where F is the force applied on the desk and d is the displacement of the desk.
Solution:
As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =
W = F*d
= 500*1.5
= 750 J
Thus, the correct answer would be option C.
