Rewrite the sentences:
1. all matter is made up of tiny particles calles atoms and molecules
2. right
3. right
4. compounds are chemically joined together
task 2:
1. i know this is element
2. i know this is compound
3. i know this is mixture
task 3:
In this lesson i have learned that Atoms are in everything and are what makes up most of the stuff on earth. They are tiny molecules that make up me and everything around me. I have also learned that atoms are made up of Elements. Elements are chemical molecules that make up things like the air we breathe. However, when more than one element joins together a compound is formed. Compounds make up more physical things around me such as drinking water and salt for cooking. When many different compounds are joined together a mixture is formed. An example of a mixture can be sand and water.

The oxygen atoms have electrons more often than hydrogen.
Explanation:
Step 1: Copy of one side of DNA strand is made (called mRNA, messenger RNA)
step 2: mRNA moves to cytoplasm, then ribosome
step 3: mRNA goes through ribosome 3 bases at a time
step 4: transfer RNA (tRNA) matches up with the open DNA bases
step 5: tRNA releases the amino acid at the top, which joins the chain of amino acids being produced
The renal corpuscle consists
of a capillary bed called the glomerulus and a capsule of epithelial cells.
The renal corpuscle is composed
of two structures, the glomerulus and the Bowman's capsule. The glomerulus is a
small tuft of capillaries containing two cell types. <span>It is also characterized
as a cluster of capillaries around the end of a kidney tubule, where waste
products are filtered from the blood. Other
surfaces that separate body cavities from the outside environment are lined by
simple squamous, columnar, or pseudostratified epithelial cells.The gastrointestinal tract, the insides of the lungs, and the
reproductive and urinary tracts where other epithelial cells line up make up
the exocrine and endocrine glands.</span>

Hello YOU!
Explanation:
Phrenology was a science of character divination, faculty psychology, theory of brain and what the 19th-century phrenologists called "the only true science of mind."Phrenology came from the theories of the idiosyncratic Viennese physician Franz Joseph Gall (1758-1828).
Gall believed that the bumps and uneven geography of the human skull were caused by pressure exerted from the brainunderneath. He divided the brain into sections that corresponded to certain behaviors and traits that he called fundamental faculties. This is referred to as localization of function.
Phrenology is considered pseudoscience today, but it was actually a vast improvement over that era's prevailing views of personality. ... But phrenology may be undergoing a redemption of sorts. Not the skull part—that's still considered bunk.
Phrenology was particularly popular in the U.S. because it fit so well with the idea of the American dream–the notion that we can accomplish our goals despite a humble heritage. Spurzheim believed that the brain was like a muscle that could be exercised.
