#1 is D) uniformitarianism
Answer:
Have larvae which are motile and move via the motion of cilia. (Ans. A)
Explanation:
Sponges: They are belongs to porifera phylum and defined as the simplest species. In sponge for particular function they are containing specialized cells, and they lack true tissues. All sponges are marine or aquatic in nature.
Sponge lives in contact with water because it helps them to excretion, gas exchange, and feeding. They can filter out the food, eliminate waste, and absorb dissolved oxygen with the help of body structure of sponge is dedicated to moving water.
Sponges produce motile larvae through the process of sexual reproduction, and move with the motion of cilia or budding formation through the process of asexual reproduction.
The scale reads 3 so it is displacing 5 kg of water
find volume of rock using volume of water it displaces:
volume of rock = 5 kg(m^3 / 1000 kg) = .005 m^3
mass of rock = 8 kg
density = 8 / 0.005 (kg/m^3)
1600 Kg/ m^3
1. A
2. i think B but i’m not sure
3. C
I hope this helps ! :)
<span>Its when your oxygen level drops down below normal levels while you are asleep. My sister was diagnosed 10 years ago with several sleep apnea and had his tonsils, adenoids, and some of her soft pallet removed.
