Normally they have equal protons and neutrons
Answer:
In mammals, oxygen is carried through the red blood cells called hemoglobin. The reason is that the oxygen is very important for the cell for releasing energy. This energy is used by the cell in different processes.
2) These adaptations are adapted by the organisms in order to perform different functions. In slow twitch skeletal muscles having high number of mitochondria because it requires more energy while fast twitch skeletal muscles contains less amount of mitochondria due to low requirements of energy. These characteristics are adapted according to the performance of the body parts.
answer:
it took 17,000 years for CO2 to go from 200 to 300 ppm.

Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.

<u>Answer:</u>
"G-Factor" is associated with a theory of intelligence proposing a singular underlying aptitude or intellectual competence of intelligence.
<u>Explanation:</u>
An English psychologist Charles Edward Spearman was highlighted for his work in statistics as a pioneer of factor analysis. He speculated that humans had "G-Factor" i.e general intelligence (established in 1904 by Charles Spearman) from very early in the measurement of intelligence in history.
G-factor is a singular underlying aptitude or intellectual ability in many fields which include verbal, reasoning and spatial abilities. The general intelligence tests the level of expertise in applying logic to solve work-related problems by measuring the basic cognitive abilities regarding specific skills like memorization, arithmetic and common global knowledge.
