An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.
What is an Open circulatory system?An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.
Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.
Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

a skeletal muscle generates the greatest tension when it is:
Explanation:
A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated
Skeletal Muscle generates the greatest tension when the muscle is stretched to an intermediate length, by length-tension relationship.
How tension generates in skeletal muscle?Muscle tension is highest in skeletal muscles when stretched to an intermediate length, as indicated by the length-tension relationship.
When skeletal muscle fiber contracts, myosin heads link to actin to create cross-bridges, and the thin filaments slide across the thick filaments as the heads pull the actin, resulting in sarcomere shortening and muscular contraction stress.
The amount of stress produced by a muscular contraction is determined by two factors: the number of active muscle fibers and the frequency of neural stimulation of the muscle fibers.
Therefore greatest tension generates in skeletal muscle when it is stretched to the intermediate length.

Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
As a cell matures, genes that are not necessary to its function are ejected out of the cell through active transport.
The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.
A developing cell's function is determined by the number of organelles that are contained in the cell.
Through the mitotic process, two identical diploid daughter cells are produced. Mitosis is preceeded by the interphase and followed by cytokinesis. 7) b. / 8) a. / 9) b. / 10) b. / 11) c. / 12) a.
-------------------------------------------------
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage. During the S stage occurs the DNI molecule replication process. At this point, also happens the synthesis of histones and other associated proteins. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Daughter cells are identical to the original cell.
Mitosis occurs in only one phase, divided into four stages.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.Each chromatid joins with a microtubule of opposites poles.
In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles. In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, cytokinesis occurs.

Answer:
Viruses used in gene therapy are retroviruses, adenoviruses, adeno-associated virus, herpes simplex, and vaccinia. Retroviruses are most commonly used because they can incorporate their genetic material into the host cell’s DNA, thus changing the genetic component of that cell.
Explanation:
Gene therapy is a medical field which focuses on the genetic modification of cells to produce a therapeutic effect or the treatment of disease by repairing or reconstructing defective genetic material. The first attempt at modifying human DNA was performed in 1980 by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. It is thought to be able to cure many genetic disorders or treat them over time.

What should be done with the contents of
a composter? Explain your reasoning.
Answer:
Finally, the number of times the pile is turned influences composting speed. By turning more frequently (about every 2-4 weeks), you will produce compost more quickly. Waiting at least two weeks allows the center of the pile to heat up and promotes maximum bacterial activity. The average composter turns the pile every 4-5 weeks.
When turning the compost pile, make sure that materials in the center are brought to the outsides, and that materials from the outside edges are brought to the center.
With frequent turning, compost can be ready in about 3 months, depending on the time of year. In winter, the activity of the bacteria slows, and it is recommended that you stop turning the pile after November to keep heat from escaping the pile's center. In summer, warm temperatures encourage bacterial activity and the composting process is quicker
Using compost in the yard
Incorporate compost into your garden as you prepare the soil in the spring. Cover the area with 3-4 inches of soil and till it in to at least the upper 6 inches of soil. Add compost to soil in vegetable gardens, annual flower beds, and around new perennials as they are planted.
You may also use compost as mulch around flower beds, vegetable gardens, or around trees or shrubs in landscape beds. Apply a 3 inch layer. Be careful not to apply mulch close to the main stem or trunk of the plant.

what organelle do both plant and animal cells have that control all of the activities that take place inside of a cell?
Answer:

Explanation:
green and yellow wavelengths of light are not useful to most plants.
The statement that green and yellow wavelengths of light are not useful to most plants is incorrect. In fact, green and yellow wavelengths of light are essential for plant growth and photosynthesis.
Plants primarily capture light energy for photosynthesis using specialized pigments called chlorophylls, which are most efficient at absorbing light in the red and blue regions of the spectrum. As a result, the green wavelengths of light are reflected rather than absorbed by chlorophyll, giving plants their characteristic green color.
While it is true that green light is less absorbed by chlorophyll compared to other wavelengths, it still plays a vital role in photosynthesis. Green light is still partially absorbed and contributes to energy transfer within the plant, helping drive the photosynthetic process.
Moreover, certain types of plants, such as shade-tolerant plants or plants adapted to low-light conditions, have chlorophyll pigments that are more efficient in capturing green and yellow wavelengths of light. These plants can utilize a broader range of light wavelengths for photosynthesis, including green and yellow light.
Therefore, green and yellow wavelengths of light are indeed useful to most plants. While red and blue light are more efficiently absorbed, green and yellow light still contribute to the energy needs of plants and play a role in photosynthesis.

Where in the cell would you expect to find the greatest activity of the pyruvate dehydrogenase complex?
Answer:
Mithochondria
Explanation:
In eukaryotes, the pyruvate dehydrogenase complex, like the enzymes for citric acid cycle and oxidation of fatty acids, is located in the mitochondrion, where is associated with the surface of the inner membrane facing the matrix.
In the cell, mitochondria are the place where it expects to find the greatest activity of the pyruvate dehydrogenase complex.
What is the pyruvate dehydrogenase complex?The three-enzyme complex known as the pyruvate dehydrogenase complex (PDC) is responsible for pyruvate carbonylation, which converts pyruvate to acetyl-CoA.
This complex connects the glycolysis metabolic pathway to the citric acid cycle by allowing acetyl-CoA to be used to perform cellular respiration.
The enzyme pyruvate dehydrogenase catalyzes the reaction between pyruvate and a lipoamide, which yields acetylated dihydrolipoamide and carbon dioxide. The process requires the coenzyme thiamine pyrophosphate.
Therefore, the site where you find the greatest activity of the pyruvate dehydrogenase complex is mitochondria.

Does “survival of the fittest apply to domesticated animals? Why or why not? *
Answer:
Yes.
Explanation:
This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.
Answer:
Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.
Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.
However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

What is the name of the organelle in the leaves of plants that absorbs the sun's energy?.
Answer:
The name is chloroplasts
Explanation:
in cells regulation allows rapid response to changes in the environment; in cells, gene regulation is critical for maintaining homeostasis.
Given what we know about biological mechanisms, we can confirm that both of these statements are in fact true in regards to regulation and gene expression.
Homeostasis is the body's ability to maintain constant a series of processes and values that we need in order to survive. To do this, regulation in cells is essential. Regulation allows us to respond rapidly to changes in the environment by regulating the processes which control the homeostasis for that environmental change.
Gene regulation or expression is another way in which the body maintains homeostasis. For example, in the presence of too much substrate, the gene encoding a specific enzyme might activate, causing the creation of the enzyme and getting substrate levels back to normal.
Inversely, if the body detects that substrate levels may be too low, the expression of any gene that may consume that substrate can be silenced, therefore maintaining a balanced level.
