The red blood cells are cohesive, meaning they want to stick together. if one cell moves along the capillary this cohesion will drag the neighboring cell with it. the cells are also adhesive to the capillary walls, so they stick along the tube lining as they are dragged through the capillary.
Answer:
Just convert, 37 degrees Celcius into Fahrenheit is: 98.6
Answer:
The answers are Tubercle and keeping the body balance over the feet, the hability of standing, avoid the body to fall, ankle plantarreflexion and foot evertion
Explanation:
The peroneus brevis muscle is located on the lateral side of the leg and it is a fusiform, and, short muscle, that becomes a tendon and passes behind the lateral malleolus. The tendon is inside a synovial sheath. It passes foward and downward into a groove above the peroneal tubercle on the calcaneous. The distal attachment of the peroneus brevis is the tubercle on the lateral side of the base of the first metatarsal. The mechanism is responsible for foot evertion, ankle plantarreflexion, because the tendon's position, which pulls the foot in that direction. The advantange is that this mechanism garantees important functions such as stops a sideway sway when a person is standing, controlling the body from falling to the opposite side when standing on one leg (keeps the body balanced)
Controlling the position of the foot and stopping the foot from being inverted . Sometimes the foot can over invert causing weight to be applied to the lateral surface of the foot.
Answer:
the peroneus longus (also known as fibularis longus) is a superficial muscle in the lateral compartment of the leg, and acts to evert and plantarflex the ankle.

Answer:
This is because humans are causing species to go extinct at a faster rate than the normal rate.
Explanation:
It is documented that there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years. Some may say even if nothing is done there would still be extinction of this species which is true.
We care if human activity is driving other species extinct as we grow because humans are causing species to go extinct at a faster rate than the normal rate.
The average speed of the zebra during time between 0s and 40s is 34 seconds.
The average speed, a scalar value which is greater than or equal to the magnitude of the average velocity of a substance.
In general speed = distance / time
it is calculated by dividing the total distance travelled by the
total time taken for the substance to reach the destination.
If the average speed is zero which is equivalent to average velocity.
If the direction of the path has been changed then the average speed will be greater than the magnitude of the average velocity
The average speed of the zebra during time between 0s and 40s is 34 seconds.

colors one blue and one red. What is the significance of the two different
strands? Are they both used in transcription?
3. There are two required components to initiate transcription on the gene. What are they,
and where do they bind on the DNA strand?
4. How would you know if transcription has been successful?
5. How do negative transcription factors impact transcription?
6.Explain the difference in transcription between Gene 1 and Gene 2. Hypothesize the reason for the difference.
Answer:
Here are my answers to your questions:
The regulatory portion of the gene is a sequence of DNA that controls the expression of the gene. It may contain binding sites for transcription factors, which are proteins that activate or repress transcription. The regulatory portion of the gene may also include elements such as enhancers, silencers, and insulators, which can influence the rate and specificity of transcription12.
The two different strands of the DNA molecule are called the template strand and the coding strand. The template strand is the one that is used by RNA polymerase to make a complementary RNA transcript during transcription. The coding strand is the one that is not used by RNA polymerase, but has the same sequence as the RNA transcript (except for T instead of U). Both strands are important for transcription, but only one is directly copied34.
The two required components to initiate transcription on the gene are RNA polymerase and a promoter. RNA polymerase is the enzyme that synthesizes RNA from a DNA template. A promoter is a sequence of DNA near the start of a gene that signals RNA polymerase where to begin transcription. RNA polymerase binds to the promoter with the help of general transcription factors, which are proteins that recognize specific features of the promoter15.
Transcription has been successful if a complete and accurate RNA transcript has been produced from the DNA template. The RNA transcript can be detected by various methods, such as hybridization with a complementary DNA probe, electrophoresis on a gel, or sequencing1.
Negative transcription factors are proteins that repress transcription by binding to DNA and preventing RNA polymerase or other activators from accessing the gene. Negative transcription factors can regulate gene expression by turning off genes that are not needed or harmful in certain conditions67.
Gene 1 and Gene 2 have different transcription rates because they have different regulatory elements and transcription factors. Gene 1 has an enhancer and an activator that increase its transcription, while Gene 2 has a silencer and a repressor that decrease its transcription. These elements and factors may respond to different signals from inside or outside the cell, such as hormones, nutrients, or stress68.
Answer:
1. The coding region of a gene is used to make RNA molecules. This region is controlled by regulatory portions of the gene, which are located upstream of the coding region and determine when, where, and how much they are expressed. When it is time to express a gene (turn it on), when it's not the right time to express a gene (turn it off), lastly if expression needs to be enhanced (increase the amount of protein being produced).
2. In this diagram, one strand represents the coding strand, while the other represents the template strand. The template strand acts as a model for RNA polymerase to synthesize mRNA. The template strand is read by the polymerase, and complementary bases are added to form the mRNA.
3. Two components are required to initiate transcription, including RNA polymerase and transcription factors. In addition, there is also a promoter on the gene, which acts as a sort of "entrance" for the RNA polymerase to bind and begin transcription.
4. If transcription is successful, then you would expect to see RNA being produced.
5. In order to begin transcription, the RNA polymerase/general transcription factor must bind to the promoter. There are different types of transcription factors such as activators and repressors. If a repressor binds to the promoter, this effectively "blocks" the RNA polymerase.
6. There is a difference in transcription rates between Gene 1 and Gene 2 due to differences in regulatory elements and transcription factors. There are enhancers and activators that increase Gene 1's transcription, while silencers and repressors decrease Gene 2's transcription. Signals coming from inside or outside the cell, such as hormones, nutrients, or stress, may trigger these elements and factors.
