Will mark brainliest if the answer is correct: ""how does the presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates?""
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.
The presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates because the nephrons are similar to that of reptiles and mammals and other birds and vertebrates.
What are nephrons?Nephrons are the functional unit of the kidney. There are many nephrons present in a kidney, it contains tubules and corpuscles.
The formation of urination is done by nephrons, the three functions of nephrons are filtration, reabsorption and secretion.
Thus, the presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates because the nephrons are similar to that of reptiles and mammals and other birds and vertebrates.

Obliquity or tilt is the inclination angle of the Earth's axis. It is responsible for seasonal changes. The correct option is A) The tilt of the Earth is responsible for the seasons.
What is the Earth's obliquity -tilt-?The term obliquity or tilt refers to the inclination of the axis of the Earth. The plane in which the Earth orbits around the sun is not orthogonal to the Earth’s axis of rotation. The axis has an inclination angle called ecliptic obliquity.
Obliquity is a determinant of seasons' existence. Thanks to this inclination in the axis of the Earth there are seasons. If tilt would equal cero, there would not be any season or temperature change in different regions of the Earth. So tilt becomes a significant factor, especially for high latitude areas.
Obliquity is one of the three Milankovitch cycles, together with precession and eccentricity. These are used to explain natural climatic changes through the history of the Earth.
The correct option is A). The tilt of the Earth is responsible for the seasons.

Answer: The correct answers should be the hares will multiply indiscriminately and destroy the ecosystem and the native herbivores will experience increased competition for resources.
Since the hares wouldn't have predators, and they are famous for rapid breeding, they would overpopulate the ecosystem. On the other hand, the native animals would have to compete with this population of hares for food and would have less for for themselves.

summarize how enzymes are made. (3 points)
Explanation:
The chemical reactions involved in photosynthesis are controlled by enzymes . As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate.
Enzymes are biological catalysts - they speed up chemical reactions. The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.
Enzymes are required for most of the chemical reactions that occur in organisms. These reactions occur in the breakdown of chemical molecules, which we see in the digestive system.
