Answer:
It has 0.82 moles of gas
Explanation:
Given:
The Volume of gas = 30 L
The pressure of the gas = 0.7 atm
Temperature =315 K
To Find:
Number of moles of the gas = ?
Solution:
According to Ideal gas law
PV =nRT
where
P is the pressure
V is the volume
T is the temperature
n is the number of moles
R is the gas law constant
On substituting the given values in the formula, we get
(0.7) (30) = n (0.0817)(315)
21 = n (25.7355)
n = \frac{21}{25.7355}
n= 0.8159
n = 0.82(rounding off)
Answer:
mitochondria
Explanation:
the mitochondria act as the powerhouse of the cell, creating energy for the cell to use.
Answer:
The vegetative cells found in all the kinds of organisms that form the body of an organism are known as somatic cells. They are found in both multicellular and unicellular species. In humans, a somatic cell comprises 46 chromosomes with 23 pairs coming from each parent. However, these cells are non-reproductive.
On the other hand, the gametes refer to the cells that are considered as the reproductive cells of the organism. They are also known as sex cells as they develop into sperm and egg cells. These cells are haploid in nature, and they are formed at the time of meiosis.
Answer:
<em>Escherichia coli </em>- Facultative anaerobe
<em>Micrococcus luteus </em>- Obligate aerobe
<em>Clostridium sporogenes</em> - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are <em>Mycobacterium tuberculosis </em>and <em>Micrococcus luteus</em>.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the <em>Escherichia coli</em><em>.</em>
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are <em>Clostridium sporogenes</em><em> </em>and <em>Clostridium botulinum.</em>
The answer is:
P and T - directly <span>proportional
P and V - </span><span>inversely proportional
T and V - </span>directly <span>proportional
P and n - </span>directly <span>proportional
V and n - indirectly proportional
The ideal gas law can be presented as:
PV = nRT
where
P - pressure of the gas,
V - volume of the gas,
n - amount of substance of gas,
R - gas constant,
T - temperature of the gas.
If both members of a pair are on the same side of the equation, they are </span>inversely proportional. If two members of the pair are on opposite side of the equation, they are directly proportional. For example, P and V are on the same side of the equation, so they are inversely proportional. This means that if P increases, V must decrease and vice versa. P and T are on the opposite sides, so they are <span>directly proportional. This means that if P increases, T must increase, too, and vice versa.</span>
