The correct option is D.
Parietal cells are the epithelial cells which secrete hydrochloric acid and intrinsic factors. The cells are located in the gastric glands which are found in the linings of the walls of the stomach. The hydrochloric acid produced by the parietal cells helps in the conversion of the enzyme pepsinogen to pepsin during the digestion process.
Answer:
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions.
the very basic properties of water
conducts heat
neutral pH
high surface tension
high specific heat
good solvent
how does this help a polar bear, some of it is a stretch but possible benefits
pH - good drinking water, good for marine ecosystem for food
high specific heat - can absorb lots of heat before the temperature rises, polar bears exist naturally in cold environments. (ice) - maybe can tie this in with the natural hibernation cycle
high surface tension - I'm assuming the polar bear walks on the ice at times to get fish
as a good solvent - its probably good that most things dissolve in water, otherwise we would have a lot of floating gunk on top of the water
outside of this, can't give you much more. it has been noted in Shishmaref Village that the ice caps melting is leading to a lack of water in higher mountain areas and polar bears are coming down from the mountain ice cap areas to find food and water
Plant Breeding and Predicting Offspring Traits
By Patty Hain - croptechnology.unl.edu
Introduction
Kernel color in an easily observable trait. There are different alleles of the ‘kernel color’ gene that code for different colored kernels. For example, one allele represented with Y (upper-case) encodes yellow colored kernels. Another allele for the color trait encodes white colored kernels represented with the y (lower-case).
