Explanation:
Worms are invertebrate animals with bilateral symmetry. Worms have a definite anterior (head) end and a posterior (tail) end. The ventral surface of worms and other organisms is the bottom side of the body, often closest to the ground. The dorsal surface is located on the upper part of the body facing the sky. The lateral surfaces are found on the left and right sides of the body. Figure 3.35 compares bilateral symmetry in a whale shark and a swimming plychaete worm. Organs for sensing light, touch, and smell are concentrated in the heads of worms. They can detect the kinds of environment they encounter by moving in the anterior direction

hope this helps!
I'm pretty sure that it's C. I'm not quite sure though.
Answer:
During the method of photosynthesis, daylight is employed to convert water and dioxide into aldohexose and gas. light-weight reactions convert the energy in daylight into the energy of ATP and NADPH.
a) In the bright daylight, the Calvin cycle happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are accustomed convert molecules of carbonic acid gas into high-energy sugars.
b)In the darkness, the Calvin cycle conjointly happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are used to convert molecules of CO2 into high-energy sugars.
c) There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be continued.

Answer:
A. spiral galaxies are not pinwheel-shaped
Explanation:
There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.
Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.
Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.
Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.
Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
