Answer:
Heterozygosity
Explanation:
The correct term that could explain the phenomenon is heterozygosity.
<u>In heterozygous condition, a gene is made up of two different alleles in which one would be dominant and the other would be recessive. </u>
<em>In heterozygous purple plants in which the alternate color is white, the white color is not expressed because its allele is in a recessive state. If two heterozygous plants are mated, the recessive allele in each plant would combine into some of the offspring, resulting in the production of white color progeny in addition to the dominant purple color progeny.</em>
Let us assume that the purple color allele is P and the white color is p.
Pp x Pp
PP Pp Pp pp
PP and Pp - purple color
pp - white color.
Answer:
from the splitting of water molecule.
Explanation:
The splitting of water molecules by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis of enzymes of Photo system 11.
It involves the splitting of water molecules into;
hydrogen ion/protons.
Oxygen
and electron.
<u> Oxygen is the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.
the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02 to form carbohydrate in light independent reaction
Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
The answer should be proteins. Because the protein is consists of different kinds of amino acids(usually 20 in total). And our cell can not produce essential amino acids itself.
1. Answer:
Both these leaves are quite similar because of their physical appearance. <em>The sea teak leaf and weeping willow leaf are narrow and elongated. However, a weeping willow leaf has tapered edges.
</em>
The scientific names of sea teak and weeping willow plants are Podocarpus polystachyus and Salix babylonica.
- The leaves of both these plants are simple regardless of their receptive compound appearance. This is due to the presence of complex vein structure on the leaf.
2. Answer:
<u>There many differences between sea teak leaf and weeping willow leaf.</u>
Sea teak leaf is 3-10 cm long while weeping willow leaf is only 6 cm long.
Sea teak leaves are bright green and shiny while weeping willow leaves are green at top and white at the bottom.
<em>The bark of weeping willow can be used to obtain various medicines. Meanwhile, the leaves of sea teak plants are chewed to ease pain of joints.
</em>
<u>Weeping willow trees are found in areas of China, South-West Asia and Europe.
</u>
<u>Sea Teak trees are found in Indonesia, Malaysia etc.</u>
