Answer: trachea
Explanation:
During inhalation, air moves from the larynx into the trachea. Air enters the oral cavity, and then it moves into the pharynx.
<span>Ans: G1 phase
Explanation:
Preparation of a newborn division happens in three steps:
G1 phase, G2 phase and S phase.
In G1 phase, the cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps.
mitosis is the process in which the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules.</span>
Answer:
A fungal cell is an eukaryote with all intracellular, membrane bound organelles. A bacterial cell is basically a prokaryote with a nucleoid. The cell wall composition also varies. It is a lipopolysaccharide layer called peptidoglycan layer in bacteria whereas cell wall of a fungal cell contains complex polysaccharides called chitin and glucans. Bacteria are either autotrophic or heterotrophic whereas fungi are strictly heterotrophic. Bacteria reproduces asexually by binary fission whereas fungi can reproduce either by sexual or by asexual method. Dormant form of fungal cell are called conidiospore or basidiospore or zoospore or ascospore based on their location in hyphae and type of reproduction. In bacteria, dormant forms are called endospores.
<span>Aside from absorbing water and nutrients in the
ground, roots are also the very support of a tree. It supports bigger trees to
stand and stay steady against heavy rains and strong winds. Roots are also
capable of absorbing water that may cause flood in the area, and support slopes
that may result to landslides. Roots are very important because it lessen the
chances of soil erosion in a certain place. Roots can also be used for plant
vegetations.</span>
Answer:
As this is DNA replication, this is the unwounding process
Explanation:
In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-anealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwounding. An example is the gyrase
