Gene pool
Sum of a population's genetic material at a given time.
The term typically is used in reference to a population made up of individuals of the same species and includes all genes and combinations of genes (sum of the alleles) in the population.

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has

Dima020 [189]

Answer:

The unearthed Humerous bones don't belong to the species A.

Explanation:

Hello!

You are studying the Humerus bones species A, who is known to have a mean ratio of 8,5. This value corresponds to the population mean of the length-to-with ratio of bones of species A, symbolized as μ.

The hypothesis you want to study is "The Humorous bones unearthed belong to the species A" if you assume this to be true, then the mean of the length-to-with ratio should be equal to the known population mean of the length-to-with ratio.

Symbolized:

H₀: μ = 8,5

H₁: μ ≠ 8,5

Significance level: α: 0,05

You are asked to use a Z-test, since you don't know the value of the population variance, but have the sample values, the sample size is big enough (more than n=30). Assuming that the sample values are independent, the statistic test of choice is the approximation:

$Z= \frac{x_bar-μ}{S\sqrt[]{n} }$ ≅N(0;1)

The critical region, in this case, it's a two-tailed test (remember the type is determined by the null hypothesis) so you'll have two critical values.

Left value [/tex] $Z_{\alpha/2} = Z_{0,025} = -1,96$

Right value $Z_{1-\alpha/2} = Z_{0,975} = 1,96So you'll reject the null hyphotesis if the calculated [tex]Z_{obs}$ value is ≤-1,96 or ≥1,96 and you'll support it if -1,96< $Z_{obs}$ <1,96

Now we calculate the statistic by replacing the formula with the data:

x_bar = 9,26

S = 1,20

n = 41

$Z_{obs}= \frac{x_bar-μ}{S\sqrt[]{n} }$

$Z_{obs}= \frac{9,26-8,5}{1,20\sqrt[]{41} }$

$Z_{obs}$ = 4,0553

Since the calculated value falls in the rejection region, this means, you have statistically significant results. In other words you can reject the null hipothesis (H₀: μ = 8,5) and asume that the unearthed Humerous bones don't belong to the species A.

I hope you have a SUPER day!

Every living cell, DNA and RNA serve as the molecules that store and transmit genetic

garri49 [273]

Answer:

Nucleic acids

Explanation:

Nucleic acids are one of the four biomolecules found in living systems ( the other three being carbohydrate, protein, lipids). Nucleic acids, like every other polymer molecule, are made up of monomeric units called NUCLEOTIDES.

The two nucleic acids are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) responsible for the storage and transmission of genetic information throughout the cell.

Pllzzz help i will give 20 points if u answer correct

Nana76 [90]

Passive transport means the cell does not have to spend energy to move gasses and fluids. the gasses or liquids go from a higher concentration to a place of lower concentration. Think about shaking a can of soda. There's a lot of pressure that builds up in the soda. When you open the soda, all of the pressure escapes to an area of lower pressure outside of the can. This is called diffusion. Osmosis is another form of passive transport. For example, in water osmosis, the water goes from a less salty solution to a more salty solution.

The correct answer is A. Diffusion and osmosis.

hope this helps =)

At 95% humidity, what percentage of the air around us is water vapour? Can you drown? ...?

NISA [10]

Humidity is the amount of water vapor in the air. Humidity varies from place to place and season to season.

There are two types of Humidity:
Absolute Humidity and Relative Humidity.

Absolute Humidity is the weight of water vapor in a cubic meter of air. The higher the temperature, the higher the ability of air to hold water. For example, at 20 C, the maximum Absolute Humidity is 17.3 g/m^3. At 50 C, the maximum Absolute Humidity is 83.0 g/m^3. Relative Humidity is the % of water vapor in the air relative to the maximum possible Absolute Humidity.

When we use the word Humidity in ordinary speech, we're talking about Relative Humidity. So, if the humidity is 95% or even 100%, that doesn't mean 95% or 100% of the air around us is water vapor; just the amount of water in the air is 95% or 100% of the maximum it can hold.

Therefore, we wouldn't drown at 95% humidity, we will be uncomfortable due to the heat content of air and water but we are still be able to breathe. I hope this answer helps.
