Tina used 500 N of force to move a desk. The desk weighed 300 N, and she
larisa86 [58]

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.

Austin and Marissa hypothesize that coneflower stomata use feedback loops to respond to moisture levels by opening when there is
zheka24 [161]

Austin and Marissa should observe the number of open stomata on one leaf, mist the leaf with water, wait one hour, and count the number of open stomata again.

In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.

Stomata, the tiny pores on the outside of leaves and stalks, control how gases enter and exit leaves and therefore, how plants as a whole function. On all periods, ranging from minutes to millennia, they adjust to regional and global changes.

Guard cells are a pair of specialized epidermal cells that make up stomata. By adjusting the size of the stomatal pore, stomata govern water loss and the exchange of gases between the plant and its surroundings.
