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.
Answer:
the 3rd option rr
Explanation:
if the seeds show a recessive trait, then it can only be when all alleles are recessive (in this case its rr).
Answer:
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
Explanation:
The aniridia allele in females has to be in the XAXA or XAXa form to be expressed but in males, can be expressed when genotype is XAY.
Migraine headaches allele in females has to be in the XMXM or XMXm form to be expressed but in males, can be expressed when genotype is XMY.
A man with normal vision and without migraines (XaY/XmY) had a father who had aniridia (XAY).
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
