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.
The structure that connects the placenta to the embryo would be the <u>umbilical cord.</u>
Yes because it is a vertebrate animal.
Answer:
Plants perform photosynthesis and cellular respiration.
Explanation:
- Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
- Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
- Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
- Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.
