Describe the pathway followed by a water molecule from the time it enters a plant root to the time it enters a plant root to the time it escapes into the atmosphere from a leaf?
A water molecule enters a plant root through specialized cells called root hairs and moves up through the xylem tissue, driven by capillary action and transpiration pull. It then flows through the stem and into the leaf where it exits the plant through tiny pores called stomata as water vapor, a process known as transpiration.
Which molecule among the following will not pass through the phospholipid bilayer of a membrane?
The molecule that will not pass through the phospholipid bilayer of a membrane is a large and polar molecule.
What is Organisms that live on land get there oxygen from?
Organisms that live on land get their oxygen from the air through a process called respiration. They take in oxygen from the atmosphere through their respiratory system, such as lungs or tracheal tubes, and then exchange it for carbon dioxide produced during metabolism. This exchange allows the organisms to produce energy through cellular respiration.
Which molecule would be unable to diffuse through a cell membrane?
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
What are the two characteristics of a molecule that will keep it from passing through a membrane and how does each keep the molecule from passing through?
Two characteristics that can prevent a molecule from passing through a membrane are size and charge. Larger molecules may be too big to fit through the pores in the membrane, while charged molecules may be repelled by the hydrophobic core of the membrane.
What is the process which heat is spread through the atmosphere by transfer of energy from molecule to molecule?
convection
What goes in and out of the external nares?
Air moves in and out of the external nares, also known as the nostrils. During inhalation, air enters the respiratory system through the external nares, where it is filtered, humidified, and warmed before reaching the lungs. During exhalation, air exits the respiratory system through the same external nares.
How a molecule of oxygen flowing through the respiratory system can be compared to a commuter driving home from work?
it cant.
What does air pass from?
Air passes through various mediums such as the atmosphere, respiratory systems of living organisms, and ventilation systems in buildings. In the atmosphere, air moves freely, influenced by temperature and pressure changes. In the respiratory system, air is inhaled through the nose or mouth, passing through the trachea and into the lungs for gas exchange. In buildings, air moves through ducts and filters to maintain indoor air quality and temperature.
Is it true that a CO2 molecule can travel from Beijing to Bangkok or from Shanghai to San Francisco for example in less than a day through atmospheric circulation?
Were that molecule in the atmosphere's jet stream, that may be possible.
Is breathing internal of external force?
Breathing is an internal force, controlled by the diaphragm and other muscles in the respiratory system. It is a vital process that brings oxygen into the body and removes carbon dioxide, essential for sustaining life.
What organ system that captures oxygen from the atmosphere?
The respiratory system captures oxygen from the atmosphere. This process occurs in the lungs through the exchange of gases in the alveoli, where oxygen is absorbed into the bloodstream and carbon dioxide is released for exhalation.
Do tiger breathe through its respiratory system?
A tiger breathes through its mouth and nose. Not through its respiratory system. It uses it's respiratory system but dosen't breath through it
What is the journey of an oxygen molecule through the respiratory system?
Nose>>>pharynx>>>larynx >>>trachea >>>bronchus >>>bronchiole >>>alveolus
What are one of the many paths a carbon molecule can take through the carbon cycle?
One path a carbon molecule can take through the carbon cycle is through photosynthesis. In this process, plants absorb carbon dioxide from the atmosphere and convert it into glucose, a form of stored energy. When animals consume these plants, the carbon is transferred into their bodies. Eventually, through respiration or decomposition, the carbon is released back into the atmosphere as carbon dioxide, continuing the cycle.
What water source is a molecule of water in once it has gone through transpiration?
A molecule of water that has gone through transpiration is typically found in the atmosphere as water vapor. It is released from plants through tiny pores in their leaves during the transpiration process and then enters the air until it condenses back into liquid form.
Significant of trachea in respiratory?
Trachea is a common term for an airway through which respiratory air passes in organismsfor an airway through which respiratory air passes in organisms
