Answer:
similarities:
1- both are nucleic acids ( made up of nucleotides )
2- each nucleotide is formed of sugar ring, phosphate group and nitrogenous base.
3- both of them contain the nitrogenous bases adenine, cytosine and guanine.
differences:
1-DNA is longer
2-DNA is the storage form of all genes while RNA has 3 types. messenger RNA which is a message of certain codes, ribosomal RNA which enters in the structure of ribosomes (synthesize proteins) and transfer RNA which carries amino acids and helps in transcription process.
3-DNA contains thymine base while RNA contains uracil
4- DNA is more stable and not easily hydrolyzed.
Answer:
The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.

Answer: the statements are not given, so I will state the role of calcium in plants.
Calcium pectate, is responsible for holding together the cell walls of plants, it is also used in activating certain enzymes and to send signals that coordinate certain cellular activities in plants. Calcium helps to maintain chemical balance in the soil, it reduces soil salinity, and improves water penetration within soil.
When there is calcium deficiency, it leads to localized tissue necrosis causing stunted plant growth, dead leaf margins or curling on the leaves, and eventual death of terminal buds and root tips of the soil/plant.
Excess levels calcium in the soil can reduce a plant's uptake of other important nutrients such as phosphorus, magnesium, boron, potassium, copper, zinc or iron, leading to deficiencies of these nutrients.
Answer:
Gastric Phase
Explanation:
Background Knowledge:
For food digestion both the nervous system and endocrine system work in collaboration with each other. Purpose of this collaboration is to increase gastric secretion soon after food is eaten and to reduce secretion when the stomach empties.
Gastric activity:
Gastric activity related to eating can be divided into three stages called the 1) Cephalic phase: Stomach Digestion is being controlled by the brain
2) Gastric phase: Stomach Digestion is being controlled by itself
3) Intestinal phase: Stomach Digestion is being controlled by the small intestine.
Find information related to three phases in attachment, attached with this answer.
Answer of the question:
About 50 to 60 % of the digestive material including Bicarbonates and biles are secreted by Gastric phase
