Butterflies undergo complete metamorphosis, and their life cycle contains 4 stages.
First, they are born as an egg.
Then, they are hatched as a larva. They now eat flowers and leaves and will molt constantly.
Next, they become a chrysalis, or a pupa. This is a resting stage.
Then is the long awaited adult stage, where butterflies take the form of the beloved, beautiful, winged insects we've come to admire. They no long grow and will now reproduce and repeat the cycle.
Hope this helps! Have a great day :)

False. Oxygen is absorbed in the alveoli sacs of the lungs.
Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.
Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.
<h3>What is blending inheritance?</h3>
Blending inheritance is an outmoded biological theory from the nineteenth century. According to the theory, children inherit any characteristic as the average of their parents' values for that characteristic.
As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.

Thus, this can be the importance of blending inheritance.

Answer:
Explanation:
If the disorder is recessive, neither parent has to have the disorder because
they can be heterozygous. The characteristic features of autosomal recessive inheritance is as follows:-
•Appears in both sexes with equal frequency
• Trait tend to skip generations
• Affected offspring are usually born to unaffected parents
• When both parents are heterozygous approx. 1/4 of the progeny will be affected
• Appears more frequently among the children of consanguineous marriages.
The given pedigree follows these features. So the correct option is 'Autosomal recessive trait'.
Please correct me If I am wrong :)
Answer: b. The radius forms the point of the elbow
c. The radius articulates to the wrist closest to the thumb
Explanation:
Ulna and radius are the two bones of the forearm. These bones articulates with the humerus and carpels of the hand.
b. The radius forms the point of the elbow: The elbow joint is the hinge joint that forms between the proximal ends of the radius and ulna in the forearm and distal ends of the humerus. The radius forms a pointed end.
c. The radius articulates to the wrist closest to the thumb: The wrist forms a complex joint. It forms a transition between the hand and the forearm. The radial deviation in the wrist forms the basis for the movement of the tilting of the wrist joint towards the thumb.
