A and C
They both can be compared to present or past objects to show how they have changed or evolved over time
The bonds that hold H2O2 together break apart and the atoms are rearranged to form water (H2O) and oxygen (O2) molecules. This happens slowly in store-‐bought hydrogen peroxide, so even in dark bottles, it will 'expire' in a year, or less if it's opened. ... And higher concentrations of H2O2 produce more oxygen.
Explanation:
Accordingly, the introductory physics laboratories have the following purposes and goals:
1. To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.
2. To familiarize students with experimental apparatus, the scientific method, and methods of data analysis so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.
3. To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic "errors." This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.
Ok I think its small polar molecules but I could be wrong.
Answer:
b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).
