critically evaluate the role of a persons rights and responsibilities when executing freedom of expression during verbal interpe
Stells [14]

A person does have basic human rights and one is the freedom of expression. Though this is the case, we should understand that our right to freely express ourselves (from political to religious views), it does not necessarily give us the right to impede another person’s. A play with words can easily hurt or even harass other people, and in return may be a form of human right violation.

11111nata11111 [884]

Answer:

a glass of muddy water

Explanation:

Pure substances contain only one element or compound.

Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.

The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.

Hope that helps.

Ancient plants begin to resemble modern plants during the Devonian period. TRUE FALSE
SVETLANKA909090 [29]

Answer:

True

Explanation:

The Devonian Period comprises the years between 416 million and 354 million and is subdivided by periods: Lower (the oldest), Middle and Upper (the most recent).

During this period, the main transformations occurred in the flora, with the exponential growth of small terrestrial plants through the development of spores. With this process, plants will become more similar with modern plants. During this period the plants were able to fertilize themselves with the seeds and reach the height of trees. They formed the first forests to be recorded, with the appearance of licopodia, ferns and progimosperms.
