Answer:
The correct answer is - warms, moist air rises.
Explanation:
When moist warm air rises and meets with the surface of cool air the more dense air that is cold air end up below the warm moist air in the troposphere it condenses as it rises.
The condensation of the warm, moist water leads to the formation of cloud formation. This cloud gets bigger and bigger until it precipitates and rain fall occurs.
They are called a population, because they are the same species living in a given area. The word population means the amount of a certain species living in a certain environment.

Answer:
Protista, Plantae
Explanation:
Protists are a diverse group of organisms with microscopic and unicellular cell structure. It includes the plant-like protists (algae), the animal-like protists (protozoans) and fungi-like protists.
Earlier Algae was classified as protista but they were unable to represent evolutionary relationship accurately and the classification was insettled. Modern taxonomy has rearranged the group and placed it under kingdom plantae on the basis of mode of nutrition is naturally autotrophic mode and mode of reproduction can be either asexual mode or sexual mode or vegetative mode.
Hence, the correct answer is Protista and Plantae in sequential order.
Answer:
Adenine 2) Thymine 3) Cytosine 4) Guanine
Explanation:
Answer:
The correct answer is option D) Albino = recessive, black = dominant.
Explanation:
- According to Mendel's Law of Dominance, of the two alleles which represent a gene, one can express itself even when in the presence of the other allele, that is in heterozygous state. This is called the Dominant allele. The other allele can express itself only in homozygous state. This is called the Recessive Allele.
- When a black guinea pig is crossed with an albino guinea pig, all black offspring (5) are obtained in the F1 generation.
- This indicates that the Black colour is dominant over the albino colour, as it masks the expressions of the albino phenotype.
- This also indicates that the genotype of the parent black guinea pig is homozygous dominant, as if it would have been heterozygous dominant then in the F1 generation there was a chance of formation of both black and albino offspring in 1 : 1 ratio.
- When a black guinea pig from the F1 generation is crossed with the albino guinea pig it gives both black (4) and albino (3) guinea pigs, roughly in the 1 : 1 ratio.
- This indicates that black guinea pig from the F1 generation was heterozygous dominant. This is why the recessive allele giving rise to the albino phenotype could express itself in the second cross.
- The second cross between F1 offspring and recessive parent is called the Test Cross.
