Answer:
1. Submit your observations of the chicken leg dissection.
The first thing that I saw was the skin. This one has bumps on it. Underneath, when I carefully cut it, I could see a yellow layer which is fat. Under the fat, there is a thick pink tissue, the muscles. The muscle is in contact with the bones and attached to them by the tendons. They look thin and white and are at the muscles' ends since they attach them to the bones.
2. Were you able to determine how the chicken moves?
Yes, muscles work in pairs, so when I pull from a specific tendon, the leg bends since the muscle contracts to do this movement. Then this muscle will relax, another muscle will contract itself, and a tendon will pull the bone to return the leg to a straight position.
When one of these muscles contracts, the other relaxes to allow the bone's movement in a specific direction. Then this muscle relaxes and allows the leg's movement in the opposite direction since the muscle that was lax before now is contracting itself to extend the leg. There are a flexor and an extensor muscle.
3. What characteristics of muscles help you determine the direction of the movement?
The characteristics that help me determine the movement's direction were:
The position that the muscles have concerning the joints and the bones. The tendons at the end of the muscles and bones.By following the muscle, the tendon, and where it is in the joint, I could determine the movement's direction.
Explanation:
When we observe a chicken leg dissection, we can determine the components that it has and how all the elements work together to move the leg. Even though the mechanism and structure are not the same as in a human body, we can see how muscles, bones, tendons, and joints work not only in animals but also in humans to allow movement.

Explanation:
This map shows the counties in Montana that are prone to dam failure. If you were in charge of flood control in Montana, where would your biggest areas of concern be? What other data would you collect about these areas or about local weather patterns to help you make a flood-control plan for the state?
Answer:
The focus would be the western side of the state and several counties in the central part of the state because there are many high-risk dams in these areas. Knowing what communities and structures are located around these dams, the average precipitation rate, and projected rainfall totals would be helpful in designing a flood-control plan. Knowing the age and condition of each dam would be important for setting priorities in the plan.

Explain how sexual and asexual reproduction both lead to better evolutionary fitness.
Answer:
Hope you get done. friend me back. and can I have brainliest
Explanation:
To get diversity in individuals, genetic differences are required, and different phenotypes must be expressed. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. Evolution can happen over time.
what would the chromosome to the right be called?
Answer:
The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis.
Explanation:
Based on the position of centromere and length of chromosomal arms, the chromosomes are classified into 4 groups:
(1). Telocentric chromosomes.
(2). Acrocentric chromosomes.
(3). Sub-metacentric chromosomes.
(4). Metacentric chromosomes.
How is meiosis I different from meiosis II? What are the products of each? How do they relate to the parent cell or to mitosis?
Answer: Meiosis I is a Heterotypic division but Meiosis II is a Homotypic division. Meiosis I produces 2 Diploid cells and Meiosis II produces 4 Haploid cells. Both produce two daughter cells from each parent cell.

Write a hypothesis about how the interaction of tectonic plates may cause earthquakes.
Answer:
hope this helps
Explanation:
Techtonic plates interacting with each other would cause an earthquake because they are essentially the earth's foundation so by sliding together they would cause rockfall and make a rumble which is basically what an earthquake is and when they interact its basically the earth moving so it would cause shaking and rumbling which is what happens in an earthquake
(Additionally) in the aftermath of an earthquake the plates are either moving or settling down which is why frequently after an earthquake there is a mini one following it
Tectonic plates can affect __________________ environmental changes, which might be a cause for species extinction

Help please -thanks!
Answer:
It is D
this shows that there was likely greater diversity during the time that is represented by that rock layer
it could also be random chance that those fossils ended up being fossilized in that location as fossilization is a random and rare occurence so this is usually corraborated with multiple locations
also remember that a mass extinction event can fit within as large of a window as over 100k years because dating isn't bang on and a large cataclysmic even could take a long time for it to effect the whole planet enough to cause a mass extinction
Explanation:
It is D
Because it shows that there was a greater diversity during the time that is represented by that rock layer , it could also be random chance that those fossils ended up being fossilized in that location as fossilization is a random and rare occurence so this is usually corraborated with multiple locations

Research and identify a common resource in your state and explain the consequences of rise in population on the resource.
Answer:
Pollution, crimes and overcrowding.
Explanation:
Lack of family planning is responsible for the rise of population. It brought many adverse changes in the environment such as pollution, crimes and overcrowding etc. Rise in population causes unemployment that leads to crimes in the society. It also produces pollution due to more human activities such as emission of fossil fuels and more industries should be built to provide basic needs to more population. Rise in population causes agricultural to be converted into residential area that leads to decrease food production.
fault generally occurs at a transform boundary. O A. normal OB. strike-slip O C. thrust O D. reverse
Answer: Read the question carefully
TRANSFORM BOUNDARIES: B. Strike-Slip
Explanation:
A reverse fault happens at convergent boundaries.
A normal fault happens at divergent boundaries
Hope this helps :)
The fault that generally occurs at a transform boundary is a strike slip. Therefore, option B is correct.
What are transform boundary and strike-slip?A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally in opposite directions. Transform boundaries are characterized by shallow and frequent earthquakes. The most famous example of a transform boundary is the San Andreas Fault in California, which marks the boundary between the Pacific and North American plates.
"Strike-slip" is a type of fault that occurs along a transform boundary, where two tectonic plates are sliding horizontally past each other in opposite directions. In a strike-slip fault, the movement is primarily horizontal and the rocks on either side of the fault move past each other parallel to the strike (or direction) of the fault. The San Andreas Fault in California is a well-known example of a strike-slip fault.
Hence, option B is correct.
