Answer:
carboxyhemoglobin
Explanation:
When Carbon monoxide reacts with haemoglobin in the blood, it forms carboxyhemoglobin which prevents the normal flow of oxygen and then it damages the central nervous system and also causes anoxia which could lead to death

what system do spiracles open into on a grasshopper
Answer:respiratory system
The spiracles on a grasshopper open to the respiratory system of the insect.
Explanation:
Describe the difference between breathing and gaseous exchange.
Answer:
Breathing is the process that moves air in and out of the lungs. Gas exchange takes place at a respiratory surface —a boundary between the external environment and the interior of the organism. ... Gas exchange occurs in alveoli in lungs. Breathing occurs through the airways.

Which of the following describes when the cell leaves the cell cycle and no longer divides?
(1 point)
O interphase
O senescence
o differentiation
O mitosis
When the cell leaves the cell cycle and no longer divides, it enters the quiescent phase.
The quiescent phase is also known as G0 phase. It is a phase in the cell cycle where cells that have no need to divide enter a perpetual resting phase until they are signalled to divide.
Once they get a signal to divide, they move from the G0 phase to the G1 phase and then proceed normally with the cell cycle. For example, cells of the neurons in humans have no need to divide unless on special occasions. Such cells stay in G0 phase perpetually.

what is osmosis meaning
Answer:
Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).
Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides...
what step of cellular respiration requires oxygen?

Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.
The step of cellular respiration requires oxygen include the following:
Pyruvate oxidationCitric acid cycleOxidative phosphorylationWhat is Cellular respiration?Cellular respiration involves the conversion of chemical energy from food
into ATP which is needed for the cell's daily activities.
It also involves series of reactions and pathways to ensure adequate
conversion and utilization of resources available. The reactions listed

VERTEBRAE
Explanation:
The traits bird and its closest relative share are eggs with shell, amniotic eggs and four limbs.
What do you mean by traits?A trait is a specific characteristic of an individual. Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure).
Simple (or Mendelian) inheritance refers to the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other. The pattern of inheritance of simple traits depends on whether the traits are controlled by genes.
Biological traits describe species' physiology, morphology, life history, and behavior, capturing both inter-specific interactions and the connections between species and their environment.

How does the concentration of organisms in a body of water affect the rate of oxygen consumption?
Answer:
oxygen is more easily dissolved into water with low levels of dissolved or suspended solids. freshwater lakes streams and tap water generally contain much less so so do concentrations are higher.
Explanation:
the amount of salt in any body of water increases, the amount of dissolved oxygen decrease
The concentration of organisms in a body of water inversely affects the rate of oxygen consumption. This is because oxygen is more readily dissolved in water.
What is meant by Dissolved oxygen?Dissolved oxygen may be defined as a measurement of the availability of oxygen in water bodies. It may also be characterized as the amount of oxygen available to living aquatic organisms.
According to the context of this question, oxygen is more easily dissolved in water as compared to other suspended solids. The availability of oxygen significantly depends on the concentration of salt.
If the concentration of salt in any water bodies like oceans, seas, etc. is higher, the amount of dissolved oxygen is lower. On contrary, freshwater lakes, streams, and tap water typically consist of less concentration of salt, and the amount of dissolved oxygen is higher.
Therefore, the concentration of organisms in a body of water inversely affects the rate of oxygen consumption. This is because oxygen is more readily dissolved in water.

How does the molecule C6H12O6 enter our body
Glucose has the formula C6H12O6. It's an essential source of energy for aerobic and anaerobic cellular respiration in all organisms. Glucose enters the body as galactose, fructose, lactose, sucrose, or starch.
What are the sources of glucose for body?Glucose is a molecule that consists of six carbon atoms and has the chemical formula C6H12O6. It is a source of energy that may be found in every organism on the planet and is necessary for aerobic as well as anaerobic cellular respiration to function properly. Glucose typically enters the body in the isometric forms of galactose and fructose (monosaccharides), lactose and sucrose (disaccharides). Glucose can also enter the body in the form of starch (polysaccharide).
When we go without food for an extended period of time, our body releases glucose that was previously stored as glycogen, which is a polymer of glucose. Through a process known as gluconeogenesis, glucose can also be produced from the byproducts of the breakdown of fatty acids and proteins.

B. The glucose enters the cell through diffusion
C. There is a net gain of water into the cell through osmosis
D. The cell is in dynamic equilibrium for the water molecules
Answer: The answer is B
Hope this helps.
a single-celled protozoan with a selectively permeable membrane that is placed in a hypertonic glucose solution. so the glucose will enter the cell by diffusion. Option B is the correct answer.
What is the tonicity of the solution and how does glucose enter in cell?Solvent and solute combine to form a solution. Depending upon the concentration of solute, the solution is of three types: hypertonic solution, hypotonic solution, and isotonic solution. The solute concentration in a hypotonic solution is less than the solvent concentration. The solute concentration in a hypertonic solution is greater than the solvent. In an isotonic solution, both the solute and solvent concentrations are equal.
When the cell is placed in a hypertonic glucose solution, the cell takes glucose into the cell by certain transporters or channels. Glucose is a polar molecule that cannot easily pass through the membrane. Hence, there are many transporters and channels present in the cell membrane. The movement of glucose is called "facilitated diffusion." No energy is required.
Hence, option B is the correct answer, as the glucose is diffused.
