The answer is C.) Sac. More formally known as the amniotic sac. It's also sometimes called the bag of waters.
Answer:
I believe the correct answer is <u>C. alveoli → bronchus → trachea → larynx → pharynx → nose.</u>
Explanation:
<u>Blood capillaries will carry the carbon dioxide from the entire body to the alveoli, the alveoli will combine to form bronchus. And so on, until carbon dioxide is exhaled from the nose.</u>
Hope I could help!
Answer:
Commensalism only occur among biotic factors
Explanation:
Abiotic factors are non-living factors that interacts with the biotic factor within an ecosystem. Commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
From the above definition of commensalism, it is clear to note that it only involves two organisms rather than non-living organisms, hence; commensalism involves only biotic factors
The options for this question are:
A. Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B. All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
C. Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
The best answer choices are:
A & C
Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
Explanation:
Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Sensory receptors located in the dermis or epidermises of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors.

Answer:
The different classes of waste produced in a house can be classified as follow: organic waste, liquid waste, solid waste and recyclable waste
Explanation:
In family homes, it is important to understand which are the types of waste in order to know how to dispose of them properly in an environmentally friendly way. First, liquid waste from the bathroom and kitchen is usually directed to the main sewer line or eliminated by septic tanks that serve as sewage collectors. Second, organic and recyclable waste is biodegradable, thereby this type of waste is usually disposed of in incinerators or landfills. Third, solid non-hazardous waste can be eliminated by compressing with mechanical systems and covered with earth to be finally compacted.
