Answer:
DNA can make loops
Explanation:
Transcriptional factors (such as activators or repressors) are proteins that regulate gene expression by binding to DNA sequence (such as enhancers and silencers). Consequently, gene transcription might be turned on or off. Usually binding sites for transcriptional factors are located near the promoter (initiation of transcription). But when they are located far from the gene they regulate DNA, flexibility plays a role. DNA can form loops which bring together binding sites and transcription factors.
Answer:
People with Rh- blood can give blood to both Rh- and Rh+ recipients. However, those with Rh+ blood cannot give to Rh- recipients. If a person receives blood from someone with an incompatible blood type, it can cause a life threatening immune system reaction.
The top box is the Myofibril. The second box towards the right (a little on the bottom of the first one) is the muscle. The third box all the way to the left is the myofilament. The fourth box on the right of the htird (towards the middle) is the muscle fibers. The last box (on the right, at the bottom) is the fascicle.

Explanation: I suggest: A freeze occurs when the temperature drops below 32 degrees, and frost can happen when the air temperature (which is measured about six feet above the ground) is up to about 36 degrees. If part of your yard is lower than the rest, it’ll probably be coldest there since cold air is heavier and sinks down.
