Explanation:
U might selectively breed cats for desired characterisitcs like having a cat with less fur or a cat with a certain type of colour.
The correct option is (C) Grow in conjunction with shedding of their exoskeleton.
The number of species in the superphylum Ecdysozoa is staggering. This is due to the presence of two of the most varied animal phyla, the Phylum Nematoda (which includes roundworms) and the Phylum Arthropoda (the arthropods).
<h3>
What do nematodes and arthropods have in common?</h3>
- The tough external covering of Ecdysozoans, known as the cuticle, is their most obvious identifying characteristic. These animals are shielded from predators, water loss, and other elements of their environment by the cuticle, which also acts as a robust yet flexible exoskeleton.
- Every member of this superphylum undergoes periodic molting, or cuticle shedding, as they develop. They produce a fresh cuticle after molting that will protect them until their subsequent growth phase.
- The process of molting and cuticle replacement, known as ecdysis, is how the superphylum earned its name.

Answer:
B. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.
Explanation:
Hershey and Martha Chase used radiolabeled the DNA of some of the bacteriophage cells with phosphorus (32P). They radiolabeled the sulfur (35S) of the coat protein in the second batch of the phage cells. They infected some of the bacterial cells with phage having radiolabeled DNA while the other <em>E. coli</em> cells were infected with the phage carrying radiolabeled coat protein. This allowed the clear identification of the radiolabelled molecule (DNA or protein) present in the host cell.
They observed that the <em>E. coli </em>cells infected with phage having radiolabeled DNA exhibited the radioactivity while the other batch of the host cell did not show it.
An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels, to more harmful effects like blocking sunlight from reaching other organisms, causing a depletion of oxygen levels in the water, and, depending on the organism, secreting toxins into the water.
