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.
Answer:
In human vision, the cone visual opsins are grouped into four photoreceptor protein families LWS, SWS1, SWS2, RH2
.
- SWS1: produce pigments sensitive to very short wavelengths, UV-violet, 360-450 nm.
- SWS2: produce pigments sensitive to short wavelengths, blue, 450-495 nm
- RH2: produce pigments sensitive to medium wavelengths, green, 495-560 nm
- LWS: produce pigments sensitive to long wavelengths, yellow-red, 560-770nm.
Explanation:
Photoreceptor proteins are light-sensitive proteins that mediate light-induced signal transduction, thus they are involved in the sensing and response to light in a variety of organisms.
The photoreceptor proteins are classified based on the chemical structure of the chromophores involved, the light absorption and on the protein sequence.
This photoreceptor proteins are located at the cone photoreceptor cells and are responsible of photopic vision.
For scotopic vision, rhodopsin is responsible. Rhodopsins are the visual pigments (visual purple) of the rod photoreceptor cell in the retina. They are responsible of human vision in dim light, as it contains a sensory protein that converts light into an electric signal.
Answer:
I think it is C.
Explanation:
coli that make the toxin are sometimes called STEC, which is short for “Shiga toxin-producing E. coli.” One especially bad strain, O157:H7, can make you very sick. It causes abdominal cramps,vomiting, and ect
Answer:
B, lung cell, lung tissue, lung, pulmonary system
Explanation:
Lung cells are also called as pleural cells. Lung cells to form lung tissue which then forms the lung and lung and its function forms the pulmonary system. The complexity increases from cell to organ system.
Pulmonary system plays a major role in respiration. Lung cells once damaged are slow to regenerate. Alveoli are the sacs in the lungs that take up the oxygen from the inspirited air and then transfers it to the tissue.
