Answer: option D) phylum
Explanation:
The linnaean system of classification from largest to smallest level is as follows:
Kingdom ---> phylum ---> class ---> order ---> family ---> genus ---> specie.
Since the phylum level consists of organisms with less similar characteristics compared to class, order and genus, we can safely say it has most organisms.
Thus, phylum is the answer.
Hey there,
From what I can recall, i can remember 2 differences.
1) Some cuttlefish have external shells, but squids have an internalized bone like structure called 'Pen'
2) <span>Cuttlefish are a group of animals of the Class: Cephalapoda, while squids are a type of cuttlefish.
Hope this helps :))

The genetic makeup of an organism as indicated by its set of alleles. heredity. transmission of genetic traits from parent to offspring. heterozygous. refers to an individual with two different alleles for a trait.
Hope this helped :)
Have a great day
<span>1) </span>Each segment of an earthworm has setae (bristly hairs), structures that enable the worm to have a grip as it burrows through the soil. The earthworm has longitudinal and circular muscles that enable it’s movements as it burrows in the soil.
<span>2) </span>When an animal exhibits cephalization, it has a concentration of nerves ending in one pole of the body, that is considered the head. While earthworm ahs ganglions in each segment in its body, its largest ganglion is found at the anterior end (the ‘head’), hence shows some degree of cephalization.
<span>3) </span>The earthworm eats up the soil and digests its organic matter while Ascaris lumbricoides, that is a parasite, absorbs nutrient through its body from the extracellular environment (host). Therefore an earthworm has a more developed digestive system than that of an Ascaris lumbricoides.
<span>4) </span>Their digestive system has a mouth and an anus. However, that of the Ascaris lumbricoides is primitive compared to that of the earthworm. Actually, flatworms have no body cavity. This is why the Ascaris is considered to be a pseudocoelomate as opposed to the earthworm that is a coelomate (contains a true body cavity).
<span>5) </span>Annelids recycle soil nutrients. By eating up the soil and digesting organic matter, they break it down to simple components that can e absorbed by the plants. As they burrow in the soil, they aerate it hence benefiting plants roots. These are important benefits in agriculture.
<span>6) </span>Annelids have a complex organ system (true coelomates) compared to roundworms. Additionally, unlike roundworms, annelids have a segmented body. They also exhibit more cephalization than either nematodes (roundworms) or platyhelminths (flatworms).
Answer:
12 links are possible.
Explanation:
Food webs are more detailed and dynamic types of food chains. In the food webs, the flow of energy occurs in a multidirectional way since within nature the food chains do not occur in isolation.
In the case of the question above, we can say that it is possible that in a community with 1 predator, 2 herbivores and 5 primary producers, 12 food web links would be generated.
This is because each herbivore would establish a 5 links representing its food through the primary producers, thus, we would have 10 links. In addition, the predator would present 2 lines indicating its consumption of each herbivore, generating two links. In the end, if we add all the links we will have a total of 12 links.
