compounds: H2O (water) H2O2 (Hydrogen peroxide) NsHCO3 (baking soda) NaCI (salt)
Element compound or mixture?: 1. Element 2. compound 3. Mixture of elements 4. mixture of compounds 5. mixture of elements and compounds.
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.
Explanation:
Answer:
Soma
Explanation:
Soma is the site at which the error of integrating an excitatory signal with other incoming signals occurred. Another name for Soma is perikaryon.
This signal integrates chemical encoding of signal transduction from all other incoming signals and this signal is not integrated properly with other incoming signals to that neuron.
Answer: C. 5 A C G U U A G G 3
Explanation:
A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis. It is a short strands of RNA.
DNA and RNA are made up of different sequence of nucleotides.
Adenine (A), Cytosine (C), and Guanine (G) are nucleotides found in both DNA and RNA.
Only DNA contains Thymine (T) and only RNA contains Uracil (U).
Pairing in DNA:
A to T
G to C
Pairing in RNA:
A to U
G to C.
Therefore DNA and RNA can still be complementary to one another by substituting for thymine (T) and Uracil (U) where required.
Starting from the underlined T (T) of the template, we have 3 T G C A A T C C 5.
If we are to pair the complementary RNA nucleotides, we will have 5 A C G U U A G G 3
