B) impossible to tell which organisms are closely related on cladogram
C) cladograms are detailed oriented and impossible to show evolutionary relationships
D) there is limited number of ways to classify information some many of cladograms end up looking similar
Ans. (C). cladograms are detailed oriented and impossible to show evolutionary relationships.
Cladistics can be defined as a method to biological classification, by which organisms are categorized in different groups on the basis of most common recent ancestor.
Cladograms only provide relations between different organisms on the basis of physical appearance and do not show genetic constitute of organisms.
Thus, the correct answer is option (C).
B. Branches.
C. Regiments.
D. Units.
Answer:

B)air enters the bloodstream
C)air is filtered and moistened
D)air is delivered to muscles
The correct answer is Option C
The air enters the nasal cavity and it is filtered and moistened their. This is done by the mucous membrane that is present on the inner side of the nasal passage.
The air is filtered and the dust particles gets attached to the mucous and the filtered air is send inside for the exchange of gases.
c.............................
B. alveolus
C. urethra
D. nephron
Ans. (D). nephron.
Kidneys are bean-shaped organs of excretory system that make urine and help in elimination of wastes from the body. Nephrons can be defined as structural and functional units of kidneys, made up of renal tubes and renal capsules.
Process of filtration, re-absorption, and secretion take place in nephrons to filter blood, make urine and excrete waste products out from the body with urine.
Thus, the correct answer is option (D).
The functional unit of the kidney involved in the filtration, reabsorption, and excretion processes is called the nephron.
The functional unit of the kidney where blood is filtered, water and other dissolved substances are reabsorbed, and waste is sent out to be excreted is the nephron.
Each kidney in the human body contains about one million nephrons. The nephron is a tiny tubular structure composed of a renal corpuscle (which is the site for blood filtration), and a renal tubule (where reabsorption occurs). Waste from this filtration is then collected and departs the kidney through the ureter, to be excreted from the body as urine.
