Most barnacles are filter feeders, sometimes known as “suspension feeders.” They feed on plankton and detritus (dead organic material), which they either sweep from the water into their mouths, using their fan-like feet, or they rely on the movement of the tide to bring the food to them.
If we cross Plant A (pink flowers) with Plant B (white flowers) of the same species, the resulting cross will give equal number (1:1 ratio) of the both colors. This means that the crossed plants had Plant A: Pp (heterozygous) and Plant B: pp (recessive homozygous) genotype.
P: Pp x pp
F1: Pp Pp pp pp
Answer:
The correct answer would be c. Ball and socket joints.
The Ball and socket joint is one of the types of synovial joint in which the round or ball-shaped end of one bone and cup or socket-like depression of other bone are complementary in nature.
The ball of one bone fits into the cup of other bone.
It provides greater freedom of movement as compared to another type of joints.
The distal bone can move around in a various number of axes all of which have a common center.
It is primarily present in the hip and shoulder joint of mammals.
All cells have a membrane of some sort some outer covering and has nucleic acid like dna or rna or dsDNA, ssDNA, dsRNA or ssRNA.
