What is checked in the GAP 2 stage of interphase?

Biology
1 answer:
EleoNora [17]3 years ago
5 0

During the second gap, or G2 phase, the cell continues to grow in size and produce proteins necessary for cell division. Microtubules, filamentous internal structures, necessary for separating the chromosome copies are made during this phase. The second internal checkpoint that determines if the cell can continue through its cycle occurs in G2. While the G1 checkpoint checks to verify DNA is error free before replication, the checkpoint in G2 confirms the new DNA is error free after replication

Cyanobacteria and purple sulfur bacteria both obtain energy from light. however, only the ________ are capable of releasing ____
kap26 [50]

Answer: Cyanobacteria, oxygen

Cyanobacteria also known as Cynophyta and blue green algae. It is a phyllum of bacteria that produces it's own food like plants by the process of photosynthesis. It is found in freshwater lakes, damp soils, oceans, moistened rocks and even in animal fur. The purple sulfur bacteria belongs to the group of Proteobacteria. It is an anaerobic bacteria. It is found in hot springs, and stagnant water. It is a photosynthesizing bacterial strain like Cyanobacteria but it does not utilize water to be reduced in the photosynthesis process like in Cynobacteria, to produce oxygen.

Hence, only the <u>Cyanobacteria</u> are capable of releasing <u>oxygen</u>.

When in danger, I can’t run from a stranger; But even when I’m in a bad mood, I can make my own food. What kingdom am I?
Anna71 [15]

<u>Answer:</u>

<em>I belong to the kingdom Plantae. </em>

<u>Explanation:</u>

<em>Plantae is one among the five kingdoms in the five kingdom classification. </em>Plants are not mobile organisms unlike organisms of other kingdoms. <em>The roots of plants hold them to the earth and thus they are immobile. </em>

Being immobile, they cannot run away from potential dangers like mobile organisms. But being autotrophs they make their own food by the process of photosynthesis. <em>Heterotrophs depend on autotrophs for food to obtain energy.  </em>

Both also contain similar membranes, cytosol, and cytoskeletal elements.
