Answer:

humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations

Explanation:

A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.

Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a

postnew [5]

Answer: C. 82.26%

Explanation:

Given : The red blood cell counts of women are normally distributed with

$\mu=4.577\text{ million cells per microliter}$

$\sigma=0.382\text{ million cells per microliter}$

Let X be the random variable that represents the red blood cell counts of randomly selected woman.

Z-score : $z=\dfrac{X-\mu}{\sigma}$

For X=4.2

$z=\dfrac{4.2-4.577}{0.382}\approx-0.99$

For X=5.4

$z=\dfrac{5.4-4.577}{0.382}\approx2.1544$

Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-

$P(4.2$

Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.

What is the function of the light-dependent reactions?

lara31 [8.8K]

Answer:

The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
