If water was nonpolar, life as it exists now would be impossible. Water is the means by which ionic substances ( Fe^3+, Na^+, Ca^2+, K^+, etc) and polar molecules are distributed around and in the cells of organisms.
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
Answer:
receive the sound and then filtration of the messages to avoid confusion.
Explanation:
Active listening process is into five stages: 1) receiving the message, 2)understanding, 3)remembering 4) evaluating the selected message, and 5) response to the message.
Receiving is the first stage of the listening skill which involves the hearing of the message and then filtration of the message. The hearing of the message involves the focused attention while filtration of the message involves the isolation of the message from a mixture of messages. The filtration is performed to avoid the mixing of the stimuli.
Thus, receive the sound and then filtration of the messages to avoid confusion is the correct answer.
Answer:
The correct answer is - Mouse - chicken - sheep - baboon - human
Explanation:
According the graph there are different group of organisms presents and the individual graph lines represnt the time they take to reach various or different carnegie stages.
To complete the 20th carnegie stage chicken takes 8 days aproximately, mouse takes 13 days and sheep takes 30 days according the graph representation.
Baboon takes almost 41 days to complete the 20th carnegie stage whereas human takes maximum time which is 55 days so , the corrcet order from fastest to the slowest would be as follows:
Mouse - chicken - sheep - baboon - human
<span>1. Bipedal gait
2. free to use hands for tools or carring capacity
3. increase in cranial capacity

Evidence points to bipedalism evolving before the expansion in human brain size. The different hypotheses are not necessarily mutually exclusive and a number of selective forces may have acted together to lead to human bipedalism. </span>
