Answer:
<h2>Only first 1 requires energy, rest all are passive transports!!</h2>
Explanation:
<h3>First one:</h3>
Here the molecules are moving from region of low concentration to high concentration, so as it is an uphill transport also known as Active transport. So active transport requires the ATP to be carried out.
<h3 /><h3>Second one:</h3>
This is the normal passive transport of hydrophobic or lipid soluble substances. So as normal passive transport requires no energy but a concentration gradient. So it doesn't require the ATP to be carried out.
<h3>Third one:</h3>
This is a transport system of protozoans like Amoeba which form a pseudopodia process around the food, and then engulf the substances which then is surrounded by vacoule for digestion to take place. It also doesn't require energy.
<h3>Fourth one:</h3>
This is an example of bulk transport mechanism where large big molecules move from higher concentration to their lower concentration through special membrane proteins and then their utilisation takes place. This is also known as Endocytosis. This also doesn't require energy to be carried out.
Answer:
DNA
Explanation:
It's the genetic material that writes up who we are.
But if it's discussing an organelle, then it's the nucleus.
Have a great day!
lac Operon of E.coil consist of three structural genes - lacZ,lac Y and lac A which are involved in lactose metabolism.These genes are regulated by a single promoter.
Explanation:
- lac operon is also called a inducible operon that is activated in the presence of lactose.
- The lac operon is responsible for the production of lactose-utilizing enzymes.
Answer: seen below
Explanation:
This is because they have gills which function through the concurrent exchange of oxygen between the water and the blood of the sharks. This water passes over the gills in the opposite directional flow of the sharks blood in the gills. So the carbon dioxide concentration in the water outside their gills increases due to increase cellular respiration in their muscles.
Therefore, it is important that sharks must swim constantly in order to keep oxygen-rich water flowing over their gills.
