Answer:paracrine
Explanation:glands are specialized tissues that secrete specific chemicals substances.these substances may be enzymes,hormones or lubricating fluid.glands secretes their their products through several mechanisms.some involve the use of ducts ,while others do not.
In paracrine secretion,the secretory products reach their target cells by diffusion through the extracellular space or adjacent connective tissue.
Paracrine secretion do not use ducts.
Similar to paracrine is the endocrine ,in which the secretory products goes through the basal lamina ,into the underlying connective tissue and into the vascular syatem.they too do not use ducts

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:
Aerobic respiration is a process glucose produces energy in the presence of oxygen. In this process glucose is oxidized to produce carbon dioxide, water and energy in the form of ATP.
C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + Energy (ATP)
Three main processes that make up aerobic respiration are:
1. Glycolysis: it takes place in the cytosol of the cell. Here, glucose is oxidized to form three carbon molecule pyruvate. This process produces energy in the form of 2 ATP molecules and 2 NADH molecules. These NADH molecules carries 2 energy electrons these electrons are utilized by the electron transport chain.
2. Kreb's cycle: it takes place in the cytoplasm and mitochondria of the cell. Here, the molecules of pyruvate produced during glycolysis is utilized to produce ATP.
3. Electron transport chain: glucose is not entirely converted into ATP. The NADH molecules produce during glycolysis produces 2 energy electrons these electrons are taken up by electron transport chain in the mitochondria inner matrix. A proton gradient develops across the matrix after donation of electrons to electron transport chain. This gradient in turn produces energy in the form of ATP.

Explanation:
Eukaryotic organisms are plants and animals, Eukaryotic stems from the word Eukarya
