Answer: in the atom you can find: electrons and protons
Explanation:
You can find electrons in an atom because it is the negative energy that rounds the atom on the outside’s part.
Then, the protons are the positive energy that is on the atom’s inside.
Both of the energies are fused and it end on a neutron energy.
Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
Explanation:
Answer:
Leukocytes are white blood cells(1, b).
Epithelial tissue is for movement(3, a).
Platelets are for blood clotting(2, c).
Muscles can be striated and volentary(4, d).
Explanation:
- Epithelial tissue helps controlling the movement of materials across the surface.
- The others are self explanitory!
Answer:
Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.
The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.
