Answer:
Yes, the species of a lizard can be identified using dichotomous keys.
Explanation:
A dichotomous key is an identification tool used by the biologists especially taxonomists to identify and classify the organisms.
The dichotomous keys are based on the characteristic feature of an organism for which two which contains two contrasting feature. The dichotomous keys are the most common tools used to classify an organism.

Answer: C. Cancer
Explanation:
Current cancer immunotherapies mainly focus on CD8+ T cells. Given the heterogeneous nature of cancer, personalized cancer immunotherapy that integrates the power of both CD8+ T cells in adaptive immunity and NK cells in innate immunity might be the future direction, along with precision targeting and effective delivery of tumor-specific, memory CD8+ T cells and NK cells.
Answer:
<u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.
Explanation:
The funny bone isn't actually a bone, its actually a nerve that touches your humerus.It is the ulnar nerve, which travels down the arm posteriorly and eventually reaches the "cubital tunnel" and at this location (between the trochlea and medial epicondyle of humerus), ulnar nerve is called funny bone.
The nerve is relatively unprotected at this place.
A blow here may produce a tingling or a numbing sensation throughout the forearm and hand.
Hence, <u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.
