Answer:
Explanation:
<u><em>Classification</em></u>: In biology, classification is the ordering of organisms into categories, such as orders, families, and genera, to show evolutionary relationships.
<u><em>Homologous Traits</em></u>: Structures that are shared by species on the basis of descent from a common ancestor.
Answer:
B) The first and second answers are correct.
Explanation:
The law of Independent assortment is one of the four laws of Mendel which states that alleles located on the chromosomes segregate or assort independently of each other.
This means that whether they are present close to each other or they are present at a distance they can be passed on in the generation together but they will show their effect on the phenotype independent of each other.
The law was concluded form the result of the dihybrid cross which showed that although the two genes were controlling the trait each allele will show its effect independent of each other or like a monohybrid result.
Thus, Option-B is the correct answer.
Answer:
An example of symbiosis is Sea anemones and hermit crabs
Sea anemones (Calliactus spp) hitchhike on the back of hermit crabs, scoring a ride across the seabed and extending their tentacles to eat the crab’s leftovers. Crabs actively recruit these passengers. After poking an anemone with its pincers – causing it to release its grip from its current home – the crab holds it in place so the anemone can reattach to the crab’s own shell.
In return, the anemones fend off hungry octopuses and other predators using their barbed tentacles. The crabs return the favour by driving away creatures that eat anemones, such as starfish and fireworms.

Answer:
<em><u>30 units</u></em><em><u> </u></em><em><u>of </u></em><em><u>energy</u></em><em><u> </u></em><em><u>will </u></em><em><u>be </u></em><em><u>available</u></em><em><u> </u></em><em><u>to </u></em><em><u>primary</u></em><em><u> </u></em><em><u>predators.</u></em>
Explanation:
Using 10 % law i.e at each step 10 % of energy is transferred to the next trophic level at the rest of either consumed or lost to environment..
so plants have = 3000 units
herbivores = 10% of 3000 = 10/100 × 3000
= 300 units
so primary predators will have = 10% of 300
= 10/100 × 300 = 30 units
