<span>Cross bridges are created when myosin heads bind to ATP. This phenomenon is basically muscle contraction at work. In order for myosin heads to be bound with ATP at the actin active site, it must be excited with Calcium.
Once myosin heads bind with ATP, it begins to slide and perform muscle contractions in the body, allowing a person to move.</span>
The complete statement will read, Complex carbohydrates are more beneficial to the body than simple carbohydrates because these types of carbs contain more overall nutrients.
<h3>Complex
carbohydrates, and simple carbohydrates</h3>
Generally, Complex carbohydrates, are a type of carbohydrates that are produced from sugar molecules that are held together in long complex chains.
While simple carbohydrates are a type of carbohydrates that are split down fast by the body of the consumer to be utilized as energy.

<span>1: global warming can harm animals and plants in the ecosystem (even ourselves). global warming is when you litter and throw trash on the ground, and also the more trash that is sent to the dump can cause global warming to get worse. Trash in the ocean can harm animals, they can eat it and get sick, or get it caught on them. It makes our earth become warmer and energy levels change. It can also hurt our atmosphere.

Answer:
The correct answer is c it inhibits the movement of small subunit relative to the large subunit.
Explanation:
According to the question the the poison that is added in vitro translation mixture containing mRNA molecules specific sequence result in formation of Met-lys dipeptide that remains attached to the ribosome.
This means the translocation step that deals with movement of smaller subunit of ribosome to the next codon(Here to the third codon) is blocked.
Complete question:
In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.
How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.
