Answer:
<u>Cartilage</u> is the flexible, tough material that makes up vertebrate skeletons or parts of the skeletal system.
Explanation:
Cartilage is the part of skeletal system that acts as a connective tissue too. It is comprised of chondrocytes cell types (formed by chondrification) and produce collagen and proteoglycan. It provides elasticity and found in the rib cage, nose, ear, and in the Intervertebral discs. It is abundantly present in infants but at later growth stages, bone maturation process takes place which replaces/hardens the cartilage with hard bones.
Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Have a great day! :)
Step 1: Imbibition water fills the seed.
Step 2: The water activates enzymes that begin the plant's growth.
Step 3: The seed grows a root to access water underground.
Step 4: The seed grows shoots that grow towards the sun.
Step 5: The shoots grow leaves and begin photmorphogenesis.
The adaptation of shoebills responds to changes in external temperature when it's too cold in their environment.
<h3>What changes occur to
Shoebills in cold?</h3>
Shoebills have adapted long toes with no webbing which helps them to balance on the swampy vegetation while stalking prey. There are few predators of shoebill storks. Young and eggs may be taken by nest predators but shoebill storks can defend their young and build nests in areas unreachable to many predators. Shoebills eat big fish such as lungfish and catfish This bird eats crocodiles and they hunt like bosses of the swamp. The Shoebill will stand there motionless like a statue. Some birds fluff up their feathers and open up their wings to catch a breeze that helping them cool.
So we can conclude that If the temperature is very cold then the Shoebill can't go outside.

Structural adaptations are the physical features of an organism, like a long trunk, thin beak, or thorns. Behavioral adaptations are things that organisms do to survive, like getting a drink when thirsty. So the correct answer is B. :)
