Respiratory bronchioles or terminal bronchioles are also part of the conducting zone.
Answer:
B.) They have the same color and texture.
Answer: Flexible springs
Explanation:
The atoms in an element or compound are bonded together by bonds which keeps the atoms together.
The bonds is stiff but it proves some flexibility for the movement of the atoms so that they can react and form different types of substances.
The bonds between the atoms act like flexible spring which keeps two or more atoms together and flexible for reacting.
The megasporangium in a pine cone is surrounded by an integument with a small opening called the micropyle.
Integuments in flowers are the maternal tissues or having a maternal beginning, as they originate from the ovular tissue or chalazal tissue (part of the lady reproductive gadget of a flower). A time period integument merely refers to the protecting layer. In terms of botany, an integument is a layer encircling the ovule.
A mature ovule consists of a meal tissue included by means of one or destiny seed coats, called integuments. A small establishing (the micropyle) within the integuments permits the pollen tube to enter and discharge its sperm nuclei into the embryo sac, a large oval cellular in which fertilization and improvement arise.

Answer:
A sewing needle floats when it is placed gently on top of water in a bucket - surface tension
Water molecules ding to plant cell walls - adhesion
A water strider runs across a pond without breaking the surface - surface tension
A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface - cohesion
Water molecules cling to the side of a beaker - adhesion
Water molecules are attracted to each other - cohesion
Explanation:
The surface tension refers to the tendency of the surface of a liquid to remain unbroken by an external force due to the cohesive property of the molecules of the liquid. Instead of being broken, the surface of the liquid stretches like an elastic membrane.
The adhesive property of a liquid, also known as the force of adhesion, refers to the property of the molecules of the liquid to stick to other molecules while cohesive property or cohesion refers to the property of molecules of liquids to stick to themselves.
Hence,
<u>Surface tension</u>
- A sewing needle floats when it is placed gently on top of water in a bucket.
- A water strider runs across a pond without breaking the surface.
<u>Cohesion</u>
- A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface.
- Water molecules are attracted to each other.
<u>Adhesion</u>
- Water molecules ding to plant cell walls
- Water molecules cling to the side of a beaker
