The littoral zone<span> is the part of a sea, lake or river that is close to the shore. In coastal environments the littoral zone extends from the </span>high water mark<span>, which is rarely inundated, to shoreline areas that are permanently submerged. It always includes this </span>intertidal zone<span> and is often used to mean the same as the intertidal zone. However, the meaning of "littoral zone" can extend well beyond the intertidal zone and that is you answer</span>

Answer:

The littoral zone is the part of the lake that is close to the shore. It exhibit very low biological activity, but contains higher oxygen content. The water in the littoral zone of lake is freshwater being unaffected by the living organisms like plants and fishes.

Answer: The correct answer is-

C.They replaced carbon dioxide with oxygen in the atmosphere.

Cyanobacteria ( also known as blue green algae) is a large phylum of bacteria that is capable of synthesizing its own food using carbon dioxide and water in the presence of sunlight ( photosynthesis).

They contain a green pigment called chlorophyll that absorbs energy from sunlight and helps in the formation of food ( glucose). They release oxygen as a byproduct in the atmosphere.

As these organisms utilize carbon dioxide ( that is present in the atmosphere) to give oxygen in return, therefore, they affected early atmosphere of Earth by replacing carbon dioxide with oxygen.

Thus, option C) is the right answer.

Describe an experiment you could perform to determine whether the pink flowers of a petunia plant result from incomplete dominan
RUDIKE [14]

Incomplete dominance is an exception to Mendelian principles of genetics. The pink flowers of a petunia plant result from incomplete dominance and this has been experimentally determined.

The crossing between petunia plants shows an exception to Mendel’s principles. As a result of crossing the first generation homozygous petunia plants, some alleles of the first cross generation of the petunia flowers were in between the two dominant alleles which meant they were neither dominant nor recessive to the characteristics.

The F1 generation produced by a crossing the red-flowered (RR) plants and the white-flowered (WW) petunia plants consisted of pink-coloured flowers (RW) as the first progeny. Neither of the allele was dominant here. The cases where one allele does not completely dominate another are known as incomplete dominance. The heterozygous phenotype is supposed to occur between the two homozygous phenotypes in incomplete dominance. Phenotype refers to the colour here and genotype is a representation of alleles.

The representation of the genotypes is as follows:

White coloured dominant parent petunia plant: WW

Red coloured dominant parent petunia plant: RR

The colours white and red are the phenotypes and WW or RR is the genotype of parental alleles.

When the red and white flowered petunia plants were true breaded which means the red and white flowered petunia plants had red and white colour as their dominant characteristic and they were homozygous.

The result that was seen of this true breeding was heterozygous pink flowered petunia plants in the F1 generation. The pink colour phenotype of the flowers was an intermediate between the two dominant red and white coloured petunia flowers. This meant that the allele for the red flowers were incompletely dominant over the white flowers giving rise to pink flowers.

The genotype of the pink coloured petunia flowers as well as the corresponding phenotype can be represented by the Punnet squares.

How are the molecules in photosynthesis and cellular respiration similar?
WARRIOR [948]

The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart
