true? i dont understand what you are asking?......
I haven't done biology in a long time but I am almost certain it is called a acrocentric chromosome.
Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA. During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs. RNA polymerase moves from the 3 'end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA. Therefore, D. Nucleic acids attach to the bases in the DNA.
The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.
<h3>What is a dichotomous key?</h3>
A dichotomous key is a methodology employed by taxonomists to identify organisms from different taxonomic groups.
The dichotomous keys are always funded on phenotypic traits.
Dichotomous keys can be considered as two different options to identify a given feature of an organism.

Answer:
keystone species
Explanation:
Keystone species are indispensable species that are essential to the maintaining of the balance of an ecosystem, and also play a major role in the way species in the ecosystem interrelate. The absence or removal of a keystone species from a habitat or ecosystem would lead to the disruption and imbalance of the ecosystem, and as such lead to the extinction of other species.
An example of a keystone species is the bee. Bees are very important in pollination of flowering plants and also ensure their survival. This plants serve as home to various insects that are source of food to birds. The removal of bees from this ecosystem would affect the ecological balance of this ecosystem.
