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.
But this on your own sentences please
Please Helppp!!! What could lead to different populations of the same species living in different environments?
Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.
Different ecological and biogeographical causes lead to different populations of the same species living in different environments. Ecological factors include intraspecific competition, migration, resource searching, habitat destruction, among others. Biogeographical dispersion involves wider areas and time factor. Human action is also a cause of dispersion.
-----------------------------------
Dispersion can be defined as the dissemination and distancing process of some individuals from others. It refers to the change in an organism's range or distribution area.
Different ecological and biogeographical processes might be involved in organisms' dispersion.
Ecological processes involve intraspecific competition for resources, habitat destruction, lack of resources -food or water-, among others. This is an intra-area, moderate dispersion that reduces competition and increases niche findings. It involves daily and seasonal migration and territoriality. Biogeographical processes refer to bigger changes that involve wider areas and time. It includes the historical factor, besides migration. This is an extra-area dispersion process.→ Jumping dispersion refers to a few individuals, in a short time, that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. They must reproduce and start a new population of a certain size that can survive the new conditions.
→ Diffusion refers to populations that, through many generations, explores and expands in new regions with favorable conditions.
→ Secular migration is the diffusion through thousands of generations.
Dispersion is also caused by human actions, following different interests and goals.When two populations of the same species migrate to new areas and adapt to different environmental pressures, they will probably suffer from the speciation process with time, becoming two different species.

Anatomy
Label each of the following structures or processes.
Answer:
A - DNA
B - mRNA
C - nuclear pore
D - tRNA
E - ribosome
F - rRNA
Explanation:
The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.
The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

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:
The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.
