The parent cell divides into two "daughter" cells. This will repeat over and over, and this is what we define as the cell cycle!
Fun Fact: Each stage of the cell cycle, such as G1 (Growth/Gap 1), Synthesis/ Stage, then G2/ Gap 2 stage, then following mitosis, has their own checkpoint! These checkpoints review/ revise what the cell has done during the stage.
Answer:
C & D
Explanation:
C - The Sun has an 11 year solar cycle. When the solar cycle is at a <em>minimum</em>, active regions of the sun are rare and not many solar flares are detected. They dramatically increase as the Sun approaches the <em>maximum</em> part of its cycle.
D - It's the Sun. It's moody. Solar flares are pretty sporadic, they're sudden and often unpredictable.
Answer:
Cis-acting sequence in bacteria that control transcription.
Explanation:
The proteins binds to Cis-acting sequences in transcription process of bacteria. This binding control the expression of one or more genes. These similar sequences are also found in eukaryotes.
The gene transfer assay helps in identifying these sequences in eukaryotes. Thus, Cis-acting sequence Controls the expression of one or more genes by serving as the binding site for regulatory proteins.
Allopatric speciation is said to occur when two groups of organisms are separated by a physical or geographical barrier. Examples of such barriers are ocean, mountain range, rivers, etc. A good example of allopatric speciation is Galapagos finch. Different species of this bird can be found in different islands at Galapos, which is located at Pacific Ocean off South America. The ocean is barrier that isolate the species from one another.
The brain and the spinal cord are the two major "organs" that you would find in the dorsal body cavity.
