Cockroaches have 6 legs and each leg has 3 knees, 18 knees in total. Since the cockroach has so many joints in its legs its can accurately pick up speed when running away from something
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.

What is oxidative phosphorylation.
Answer:
Oxidative phosphorylation is energy given by electron transport and this takes place during aerobic respiration in the mitochondria.
Explanation:
This process produces huge amounts of ATP, which is the unit of energy for metabolic processes.
Where does energy go in respiration
Answer:
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Which two atoms form an ionic bond?
A.sodium and bromine
B. two sodium atoms
C. two oxygen atoms
D fluorine and chlorine
Answer:
sodium and bromine
Explanation:
The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.
Which two atoms form an ionic bond?
Answer : A
Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).
Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.
Thus, the correct answer is option (C).

Which of the following is an advantage of sexual reproduction?
A. Produce identical copies of an organism.
B. Produce natural variation to adapt to environmental change.
C. Quickly populate a new habitat.
D. Reproduce very quickly.
Answer:
B
Explanation:
Produce natural variation to adapt to environmental change is an advantage of sexual reproduction. Correct Option is 2.
The advantage of sexual reproduction is that it produces genetic variation within a population. During sexual reproduction, offspring inherit a combination of genes from both parents, leading to unique genetic combinations. This genetic diversity results in natural variation among individuals within a population.
This variation is advantageous because it allows a population to better adapt to changing environmental conditions. In a changing environment, some individuals may possess traits that are better suited to the new conditions, making them more likely to survive and reproduce. Through natural selection, these advantageous traits can become more prevalent in the population over time, enhancing the population's overall ability to adapt and thrive.

Explain how pollution from one location
can affect the environment far away from the
source of the pollution
Answer:
Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.
Explanation:
Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.
What is Pollution?Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.
Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.

What type of shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability
Septic shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability.
Vasodilation occurs during inflammatory processes thereby leading to an increase in blood flow. Septic shock cause the release of numerous vasodilatory chemicals thereby leading to lethal hypotension.
Septic shock is caused by changes in hemodynamic profile as a result of endothelial dysfunction with increased capillary permeability thereby leading to hypotension.

What are some geological characteristics of glaciers in Glacier National Park?
Answer:
The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.

What is Plant cell?Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.
In the given figure, labelled organelles function are as follows:
Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as: vestigial structures.
Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.
These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.
Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.
