<span>The reason why the modern cockroaches have certain additional genes which allow them to survive in today’s colder climate is because of evolution. The species can grow to be able to live in certain environments. Cockroaches are to some degree summed up creepy crawlies without extraordinary adjustments like the sucking mouthparts of aphids and other genuine bugs; they have biting mouthparts and are likely among the most primitive of living neopteran bugs.</span>

The energy animals need for their life functions is released when their cells carry out which of the following functions
Vlad [161]

Cellular respiration

Explanation:

The energy animals need for their life functions are released when their cells carry out cellular respiration.

Cellular respiration is a metabolic process by which living organisms breaks down organic molecules using oxygen  especially glucose to produce energy and gives off carbon dioxide and water in the process.

It is the reverse of photosynthesis.

During this process, chemical energy stored in food substances are released and converted to heat energy.

The process takes place in the mitochondria of a cell.

From the above definition of commensalism, it is clear to note that it only involves two organisms rather than non-living organisms, hence; commensalism involves only biotic factors

Seaweeds are a [ Select ] group, green algae are a [ Select ] group, and red and brown algae represent [ Select ] groups
slavikrds [6]

Sea weeds come under polyphyletic group of the phylogeny.

What is phylogeny?

Phylogeny is the study of a species' or group's evolutionary history, particularly as it relates to relationships and lines of descent among large groups of animals.

The idea that distinct species of plants or animals descended from a single ancestor is fundamental to phylogeny and is widely recognized in the scientific community. Since the majority of animals that have ever existed are extinct and only a small portion of their fossilized remnants have been preserved in the fossil record, the evidence for these relationships is almost always insufficient. Therefore, the majority of phylogenies are based on inferential data and are hypotheses. Commonly, different phylogenies can be inferred from the same evidence.
