The liver plays an important role in the food digestion. The liver secretes bile juice which helps in the digestion of the fats. In the absence of digestion, this bile is stored in the gall bladder. The bile juice is the yellowish fluid, which aids in the digestion of fats (occurring in the small intestine) by emulsifying the fats molecules. the emulsification of these fat molecules is critical for their digestion, and absorption. Hence, the liver secretes bile juice and acts to emulsify the fat in the lumen of the small intestine.
The answer is <span>2.4 weeks
</span>
<span>x - the time in weeks
y - the heights of the plants in inches
</span><span>When both plants to reach the same height, then yA = yB
</span><span>y = 1.8x + 3.1
</span><span>y = 2.3x + 1.9
</span>2.3x + 1.9 = 1.8x + 3.1
2.3x - 1.8x = 3.1 - 1.9
0.5x = 1.2
x = 1.2 : 0.5
x = 2.4
Answer:
b: many genes code for RNAs that function directly in the cell
Explanation:
<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.
The processes that take place for gene to be successfully expressed are;
- Replication
- Transcription
- Translation
<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.
<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.
Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.
<em>The correct option is b.</em>
Answer:
The box will not move because balanced forces are acting on it.
Explanation:
According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.
An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.
From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.
