Answer:
Such glands are classified as endocrine glands.
Explanation:
Endocrine glands also known as ductless glands produce and secretes hormones (chemical substances) directly into the bloodstream to regulate the activities of cells or organs. The endocrine glands make-up the endocrine system. This system influence reproduction, metabolism, growth and many other body functions. The endocrine glands include the hypothalamus, the pituitary, thyroid, ovaries, testes, pineal gland, parathyroids, pancreas and adrenal glands.
In contrast to the endocrine glands is the exocrine glands. The exocrine glands produce and secretes their hormones through ductal system onto epithelial surface. Example of exocrine glands are sebaceous glands of the skin, the pyloric and Cardia glands of the stomach, salivary glands etc.
Answer:
<u>The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.</u>
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.

Y-purple while y-white
YY is the genotype of a pure breed purple flowered pea plant
Yy is the genotype of a heterozygous pea plant flower (purple is dominant over white)
yy is the genotype of a white flowered pea plant that is generally called as recessive
Answer:
The steps involves making hypothesis, deriving predictions from the logical consequences and then carrying out experiments based on those predictions.
Explanation:
Step 1: make a observation .
Step 2: Formulate a statement or question.
Step 3: Form the hypothesis .
Step 4: make a prediction based on the hypothesis.
Step 5: test the hypothesis whether its true or not.
Step 6: use the results to conclude the experiment.
