Answer:
They play an important role in the oxygenation of Earth's atmosphere roughly around 2.3 billion years ago.
Explanation:
Answer:
The answer is 2 milliliters or 2 mL.
Explanation:
Betamethasone is considered a <u><em>steroid medication.</em></u> It is used to treat varieties of condition such as skin rashes, arthritis and in the case above, fetal lung maturity. When it comes to fetal lung maturity, Betamethasone is usually administered to women who are in the gestation period of 34 weeks to 36 weeks, depending on the condition. It is administered through the muscles also known as "IM" or "intramuscular" and the usual dosage is 12 mg. In the case above, it is asking for the mililiters of administration considering that the order was 12 mg IM daily for three days. Since the Betamethasone comes in a 6mg/mL vial, you have to compute how much Betamethasone is to be given.
If there's 6 mg of Betamethasone per 1 mL, then this means that there's 12 mg of the medication in 2 mL.
So, the answer is 2 mL.
Answer:
K = 9.620 × 10⁻⁶
Explanation:
From the given information:
Temperature T= 6° C
= (273 + 6)K
= 279 K
The correct and well presentation of the reactions are:
1. 
⇆ oxyluciferin + light ΔG₁°
2. ATP ⇄ AMP + PP
ΔG₂° = -31.6 kJ/mol
The overall ΔG° = -4.80 kJ/mol
Let's first determine the ΔG₁° for the equation (1)
ΔG° = ΔG₁° + ΔG₂°
- ΔG₁° = - ΔG° + ΔG₂°
ΔG₁° = ΔG° - ΔG₂°
ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol
ΔG₁° = 26.8 kJ/mol
Using the formula:
ΔG° = -RTIn K
K = antilog (-5.017)
K = 9.620 × 10⁻⁶
Answer:
excitable
Explanation:
All muscle types will respond to an electrical stimulus because all muscle cells are excitable.
Excitability is response of muscle to signal which delivered through the motor neuron.
Excitability is stretching of muscles.
The contraction and relaxation of muscle occur in following way:
Muscle contraction begins with signal. The contraction occur when nervous system send signals. The impulse which is called signal is travel through a motor neuron.
The whole process include following three steps:
1) Message is traveled from nervous to muscular system and trigger the chemical reaction.
2) This chemical reaction causes the muscle fibers to reorganize in such a way that shorter the length of them which is called contraction.
3) when this signal is no longer remain , reverse chemical process occur and muscles relax.
The answer is *C. is a slow, gradual change over time*.
