Answer:
Nephrons in birds, mammals, and reptiles are all extremely similar, more so than other structures in the bodies of different species, solidifying the relatedness through similarity.
Explanation:
Birds can be said to have "mammal-like" nephrons from the number of loops and overall structure of their kidneys, which, although they look very different, serve the same purpose and do it in largely the same way. Reptiles also have mammal-like nephrons, and it can be assumed that this evolutionary trait was kept because the specific structure of the nephrons is generally the most efficient.
Answer:
Stars form large groupings
Explanation:
A large group of stars that have a common origin and are gravitationally bound for some length of time is called star clusters. Star clusters provide a way to study the ages of stars and stellar evolution. There are two categories of star clusters i.e. galactic clusters, and globular clusters.
Out of the given options, we can say that the correct option is (b) "Stars form large groupings".
Answer:
That would be option D. A motor.
Explanation:
This is called bursitis specifically olecranon bursitis. Olecranon bursa in the elbow is a thin fluid filled sac at the tip of the elbow. The bursa fills with fluid which can lead into inflammation on the surrounding area of the elbow resulting in pain and limitations of movement. Complications can happen if medical attention is not given. This includes bleeding, bruising, infectins, necrotizing fasciitis can also happen. Patient must undergo work up such as plain x rays, bone scintigraphy or if needed MRI/CT scan. Surgical interventions are usually needed because non surgical means are usually non effective. Long term monitoring is a must and patient must be advised on prevention practices.
Well, i took the test and i put artificial selection and got it right. The definition of artificial selection is "The breeding of plants and animals to produce desirable traits" So the answer is A
