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.

An organism’s adaptations are specific to its native environment. An organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. The following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in Canada, and a tropical rain forest in Belize.
Evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. In your answer, explain the survival challenges that plants face in these two environments.
Coniferous Forest
graphical representations of the temperature and precipitation in a coniferous forest from January to December
Tropical Rain Forest
a graphical representation of the temperature (top image) and precipitation (bottom image) in a tropical rain forest from January to December
Answer:
Ok so one graph shows the temperature it’s in the negative so the plant can’t survive all you have to say is the plant is struggling in the coniferous forest because of the climate there is not enough sun and not enough water the graph next to it shows the amount of water it’s getting and horizontally it’s showing the months and the plants progress the plant is barley surviving and will most likely die vs in the tropical rainforest as you can see the temperature is sunny all throughout the year it’s getting the warmth it needs and the graph next to it is again showing the amount of water it is receiving at first there’s not a lot but pushing more into spring and summer time going farther into colder whether there a lot more rain and because it’s a tropical forest the rain doesn’t turn into snow due with the warm climate it’s the perfect weather for the plant and it easily adapts to this weather because that is the natural environment plants need to grow no matter the plant they all need sun and water I hope that helped this is supposed to be a written out answer you can put it in your own words if you like or use it that way but I just did it and I got a 90% on the grade

how do organisms with many cell types develop from a single cell
Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division.
Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.
Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.
Thus, this way, organisms with many cell types develop from a single cell.

The birds do not breed with each other where their territories overlap. The birds compete for food and nesting sites. The birds compete for food and nesting sites.
Answer:
The birds do not breed with each other where their territories overlap.
Explanation:
The correct answer would be that the birds do not breed with each other where their territories overlap.
A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.
Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.
Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.

The sugars of a DNA and RNA molecule are alternated with in the backbone of the strand
Answer:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Few natural elements have a greater density than gold are plutonium, neptunium, and osmium.
What is an element?
An element is define as a type of substance that is impossible to break into smaller pieces by the help of chemical process. There are several rules that should be followed at the time of assinging name of the elements. The first rule is name of the element is not a proper noun. The second rule is the symbols of the element that must be of one or more than one symbol.
Density is define as the mass per unit volume it means that 1 kg mass present in 1 meter cube is called density, density is also states that the how compact an material.
Mathematically
Density = mass/volume
S.I unit of density is kg/m^3
Density is higher in solid as compare to liquid and density of liquid is higher than gas so density is in order of SOLID>LIQUID>GAS. So we know that solid is compact in nature as compare to liquid and gas.
Therefore, Few natural elements have a greater density than gold are plutonium, neptunium, and osmium.

What epigenetic marker changes cause chromatin to open up?
Answer Several lifestyle factors have been identified that might modify epigenetic patterns, such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts.:changes to the histone tails act indirectly on the DNA. For example, lysine acetylation may create a binding site for chromatin-modifying enzymes (or transcription machinery as well). This chromatin remodeler can then cause changes to the state of the chromatin. hope this helps ❤️❤️❤️
Explanation:
The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites.
Reasons of chromatin:It is the material that comprises of the chromosome that involved the DNA and protein. The major protein is called as the histones. It should be acted as the packaging elements with respect to the DNA.
Therefore, The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites and the gene expression is not be blocked.

MITOSIS AND MEIOSIS*Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
What meiosis means?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
What is mitosis explain?Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
What is meiosis important?Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
What is Mitosis important?Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
