In 1735 Carlous Linneaus a Botanist said that there needs to be a way to classify organisms and living things. He decided that he'll sort organisms into seven major taxa, or groupings. He called the highest taxa kingdom and the lowest taxa species. This is known as the first idea in the process of Linnaean Taxonomy.

Then in 1990 Carl Wossen a microbiologist and biophysicist added to this idea saying that he Linnaean taxonomy works well, but it could be better. Thta there could be a better way into classifying and grouping kingdoms. He then created 3 domains: Bacteria, Archaea, and Eukarya, aka, regular bacteria, extreme bacteria, and everything else.

This furthermore is the method we use in classifying living things.

The answer is: B, Domain.

1. A gas sample at a pressure of 5.00 atm has a volume of 3.00 L. If the gas pressure is changed to 760 mm Hg, what volume will

tatyana61 [14]

Answer:

V₂ = 15.00 atm

Explanation:

Given data:

Initial pressure = 5.00 atm

Initial volume = 3.00 L

Final pressure = 760 mmHg ( 760/760 = 1 atm)

Final volume = ?

Solution:

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

V₂ = 5.00 atm × 3.00 L / 1 atm

V₂ = 15.00 atm

In a mixture of 2 ideal gases, A and B, PA = 0.2PB, what is the mole fraction of A?

Alborosie

Answer:

0.1667

Explanation:

Hello,

Dalton's law defines:

$y_i=\frac{P_i}{P_T}$

A total pressure is:

$P_T=P_A+P_B$

So, for A (solving for $P_A$ in the previous equation, we get:

$y_A=\frac{P_A}{P_A+P_B}$

Since $P_A=0.2P_B$ , we obtain:

$y_A=\frac{P_A}{P_A+P_A/0.2}\\y_A=\frac{1}{6}\\y_A=0.1667$ }

Best regards.

What is the significance of enzymes in maintaining homeostasis in living organisms ?

GalinKa [24]

Enzymes are needed for metabolic pathways in the body, respiration, digestion and other important life processes. When enzymes function properly, homeostasis is maintained. However, if an enzyme is lacking or has an incorrect shape due to genetic mutation, this can lead to disease within an organism.

Compare the first ionization energy of sodium to that of potassium

stellarik [79]

Answer:

Sodium is higher than Potassium in thesame group

Explanation:

Sodium and potassium are the elements present in the first group of the periodic table. In group, atomic size increases from top to bottom this implies that even atomic radius increases. This causes less attraction force by nucleus on the electrons of outermost orbit of the atom and hence reduces the first ionisation energy, which is the energy required to remove the electron from the outermost orbit of an atom. So, as potassium is below sodium in the group, sodium has greater ionisation energy than potassium
