Cnidarians have one body opening. There is no mouth or anus. Instead, food particles are drawn into the body by movement of water. Inside the body cavity are specialized cells called amoebocytes and collar cells that help digestand remove wastes. Cnidarians with the opening at the top have body plans called polyps, such as corals. Those with the opening underneath have a medusa body form, such as jellyfish.
<u>Answer:</u>
The physiology of stationary-phase cells depends on what caused the cessation of growth.
Option: (a)
<u>Explanation:</u>
- In the physiology of stationary phase the cells then becomes spherical and later it transforms into smaller rigid cell envelop.
- The walls surrounded by the cell wall are highly crossed-linked, next the 'fluidity of the membrane reduces gradually', and there is a response given by the stringent response mechanism.
- The response is given for a certain purpose in order to survive the calamity.
The offspring will inherit one allele from each parent.
<h3><u>Explanation</u>:</h3>
The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.
One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.
The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.
Now as they are crossed the offsprings will have genetic combination of Yy.
This is seen that the offsprings carry one allele from both the parents.
The answer that would best complete the given statement above would be the second option: MUSCLES. Contractile proteins are found in muscles. <span>The muscles themselves contain muscle fibers, each of which contains cylindrical strands of </span>contractile proteins <span>called myofibrils. Hope this answers your question.</span>
