Answer:
Lightly pigmented people tend to be at higher risk of vitamin D deficiency
Explanation:
BACKGROUND KNOWLEDGE:
Human skin is the largest organ of the body which makes boundary line between environment and internal conditions. Human skin cell produces pigment called melanin when ever it is subjected to Sun. More the melanin pigment produced more will be the skin darkens. Ultraviolet (UV) radiations also come from Sun and responsible for more pigmentation.
ANSWER EXPLANATION:
According to the question darkly pigmentation only occurs when their is high level of UV radiations. High level of UV radiations are also responsible for Vitamin D production.
People with lightly pigmented means that there environment has low level of UV radiations which are the requirement of Vitamin D production. Hence due to low UV radiations peoples with light pigmentation's are also be at higher risk of vitamin D deficiency
Photosynthesis is the PROCESS of a plant making chemical energy from energy from the Sun. Energy is the input and output.
Answer:
Option C, coracoid process of the scapula
Explanation:
Coracobrachialis muscle is one of the essential muscles that is responsible for the movement of elbow along with biceps brachii and triceps muscles.
The coracobrachialis arises from the coracoid process of the scapula. It assists the elbow in flexion and internal rotation. Musculocutaneous nerve passes through the Coracobrachialis muscle and terminates at the lateral end of the cutaneous nerve of the forearm. However, the Coracobrachialis terminates at the humerus and its medial surface
Hence, option C is correct
Answer:
d. all of the offspring have medium length fur.
Explanation:
Incomplete dominance is a phenomenon in which offspring produce a trait that is intermediate between the two forms of a certain trait.
For example: In four o clock plant, some plants produce red flowers while some plants produce white flowers. When plants with red flowers are crossed with plants with white flowers, all the offspring have pink flowers.
Why is that so?
This is because no allele is completely dominant over the other and therefore both contribute their individual effect by producing intermediate phenotype.
Example in question:
Cross between a rabbit with short fur (SS) and a rabbit with long fur (LL)
P1: SS x LL
Gametes: S and L
Offspring SL :SL
SL: Medium length fur
Therefore this is a case of incomplete dominance.
Hope it help!
