Answer:
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Describe how new hair fibers are formed
Answer:
Taking nutrients from the dermal papilla, the hair bulb generates new hair cells. As these cells move up through the hair root, they mature through a process called keratinization, fill with fibrous protein and lose their nucleus.

Population, and there smaller size mean they may experience strong drift of generations.
state birth control methods according to Islam view?
help please
Explanation:
There is no single attitude to contraception within Islam; however eight of the nine classic schools of Islamic law permit it. But more conservative Islamic leaders have openly campaigned against the use of condoms or other birth control methods, thus making population planning in many countries ineffective.

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.
How are environmental issues and food production related?
Answer: Food consumption and production have a considerable impact on the environment. Food production contributes

1. Submit your observations of the chicken leg dissection.
2. Were you able to determine how the chicken moves?
3. What characteristics of muscles help you determine the direction of the movement?
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.
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.
