<h2>Answer:</h2>
Because same base pairs are arranged differently among organisms due to which there are so much variations in organisms.
<h3>Explanation:</h3>
- Variation in the organism is due to the genes.
- Every one have different DNA/genes which describes one's features.
- Genes are various arrangements of these four base pairs.
So same base pairs with different pattern arrangement causes variation among organism.
The bronchi are where air passes from the trachea.
Answer:
The correct answer is - option a. positive.
Explanation:
Nittarte reduction is the test for the determinantion of the production of nitrate reductase enzyme through various test. One of the test is trommsdroff test.
This test involves trommsdroff reagent and dilute sulfuric acid that produce blue color if the reduction occurs and reductase present. This color is formed due to the conversion of ammonia to nitrate.
The correct answer is - option a. positive.
Answer:
Hi
In the atmosphere, cloud drops form on aerosols called condensation nuclei. The formation rate of the cloud droplets is determined by the number of cores. In general, aerosols can be classified, according to their affinity with water, into hygroscopic, neutral and hydrophobic. Nucleation on a neutral aerosol needs almost the same supersaturation as homogeneous nucleation; on a hydrophobic aerosol, nucleation is more difficult and more supersaturation is required. On the hygroscopic particles, which are soluble and have an affinity with water, the supersaturation that is needed for the formation of the droplets may be less than for homogeneous nucleation.
Explanation:
Answer: A.
Explanation: Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.
