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.
These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinction of species and local populations
Ferns are pointy and mosses is not!
Crop is the part of the digestive
system you would see in a cross-section anterior to the gizzard. The crop is a
large dilation of the oesophagus and is located just outside the body cavity in
the neck region. The crop stores swallowed feed and water which are then moved
to the rest of the digestive tract while the gizzard is located after the
proventriculus behind the left lobe of the liver. The gizzard contains hard
objects that help in the disintegration of food.
Answer:
When cells split and increase they do this very important thing in order tonmake the new cells exactly the same as the previous before them. Each cell makes more of all it's genes. Then each one.splits into two with one group of genes in each one of the new cells. During the process they make sure that all are copied correctly.
