Evolution :).
Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.
The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.
The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
Answer:
a substituted derivative of purine, especially the bases adenine and guanine present in DNA.
a colorless crystalline compound with basic properties, forming uric acid on oxidation.
Answer:
The correct answer is- olfactory nerve(1)
Explanation:
Olfactory nerve is the first nerve out of the 12 cranial nerve that is located in the head and is also the shortest of all the cranial nerve. The receptors of the olfactory nerve are present in the nasal mucosa that passes to the forebrain.
It pass sensory information of smell to the brain so it plays the sensory function in smell perception. The damage to olfactory nerves can lead to:
Anosmia: In anosmia, people lose their ability to smell.
Hyposmia: In this condition, the ability to smell gets reduced.
Dysosmia: In this situation, people lost their ability to distinguish between various types of smell.
So the right answer is olfactory nerve(1).
Answer:
Doctor Who official maker and lead author Steven Moffat stated: "Osgood is back, straight from her ongoing homicide toward the finish of last arrangement. "We as of late affirmed that Osgood was unquestionably dead and not returning - yet in a show about time travel, anything can occur.
Explanation:
Answer:
Human evolution in the hominid family occurred faster than between Chimpanzees and gorillas. Neutral mutations may result in sequence divergence between organisms that are structurally similar (in this case, chimpanzees and gorillas)
Explanation:
Human and chimpanzee share higher sequence identity than predicted in the hominid family since observed mutations are necessarily associated with functional divergence
