Answer:
The correct option is D. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
Nitrogen is an active constituent of amino acids which make up proteins. Nitrogen is also an active constituent of the nitrogenous bases which make up an organism's DNA.
Phosphorus is actively present in the DNA but amino acids lack phosphorus.
Our body is actively made up of DNA and proteins. If the nitrogen was radioactively labelled, the experimental results would be wrong as proteins also have nitrogen in them.
Answer:
Blank 1: lymph
Blank 2: interstitial
Explanation:
Lymphatic system has fluid called lymph and before it becomes lymph it comes from gaps between capillaries called interstitial spaces and its fluid called interstitial fluid.
Answer:
<em>1. They effect crop productivity</em>
As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.
<em>2. They deplete the crops from nutrition</em>
The weeds will compete with the crop plants for resources such as minerals from the soil.
<em>3. They will deplete water resources</em>
The weeds will compete with the crop plants for water.
<em>4. Sun-light will be depleted</em>
The weeds will complete with the crop plants for sun light.
<em>5. The crop quality will be affected</em>
As the crop plants will be in competition with the weeds, hence their quality will be affected.
6. <em>They can reduce the biodiversity of crop plants.</em>
Answer:
Glucose
Explanation:
The glucose is a molecule stored as glycogen in the muscle cells where functions as fuel to provide energy. This molecule is also used for neurons and blood cells to provide energy
A burning liquid that is pouring over the edge of a container is known as a three dimensional fire.
<h3>What is a
three dimensional fire?</h3>
A liquid fuel fire that is discharged from an elevated or pressured source, forming a pool of fuel on a lower surface, is referred to as a three-dimensional fire. Fires that are flowing in three dimensions cannot be controlled using foam.
The best extinguishing agent for pressured liquid and three-dimensional flowing liquid fires is dry chemical. In many large spill fires if impediments are present in the spill location, they are also favored.
