Instead of thinking of the cell like a school, what else can you compare a cell to? Explain your reasoning.
vesna_86 [32]

Answer:

Explanation:

A cell can be compared to any organism that counts on different parts that have to fulfill their role for the sake of t's correct functioning, ex: a factory, a machine.

A cell can be compared to the school because every organel has a function to fulfill in order to keep the whole cell functioning in the right way. If any of the organells fails, the cell itself has to check what is wrong with it, and if the problem persists, the cell may die or replace it. The same happens with the school, it counts on different parts (teachers, directives, etc.) and if any of those parts fails, it has to be replaced before the structure itsellf gets damaged.

Jlenok [28]

The process of classifying an organism into a clade by comparing similarities in body symmetry and other morphological traits comprises - 1. body plan-based cladistics cladistics based on body plan, morphology-based phylogeny.

<h3>What is cladistics based on body plan ?</h3>

A method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.

  • Cladistics is a method of biological classification in which groups of species (or "clades") are assigned based on theories of most recent shared ancestry.
  • The evolutionary link between recent ancestors and descendants, or the course of evolution, is shown via cladistics. An aid to representing it is a cladogram. Since clades serve as the foundation for phylogenetic trees, cladistics is a component of the phylogeny.
<h3>What is molecular-based phylogeny ?</h3>

Molecule structure is used in molecular phylogeny to shed light on an organism's evolutionary connections.

  • A so-called phylogenetic tree represents the findings of a molecular phylogenetic research. DNA, RNA, and proteins are components of all living things.
  • Molecular phylogenetics creates a phylogenetic tree by drawing conclusions about the evolutionary links that derive from molecular evolution.

<h3>What is Morphology-based phylogeny ?</h3>

Using anatomical features, morphological phylogenetics infers evolutionary trees. Node: A branching point when an ancestral lineage splits into two (or more) daughter lineages in an evolutionary tree.

The ability to discuss the phylogeny of fossil taxa and how they relate to modern taxa is the unquestionable benefit of morphological data. However, their strategy prevents us from addressing the situation of extinct taxa for which there is no way to gather DNA data (i.e., almost all of them).

Amiraneli [1.4K]

Answer:

Number of bacteria required = 20000

Explanation:

Given -

Size of each bacterium = 3 micrometers long

These bacteria are arranged end to end.

The size of chain to be formed is equal to 6 centimetres

Let us say that in forming a chain of 6 centimetres nearly X number of individual bacterium are required.

hence, number of bacterium required to form 6 centimetres  chain can be represented as

X = \frac{6 * 10000}{3} \\X = 20000

Number of bacteria required = 20000
