Answer:
Ribosomes, Cell membrane
Explanation:
Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.
Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.
For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
B. A boat is moved <span>forward by a current</span>
Answer:
The correct answer is b a mutation in a gene that codes for protein regulating cell division.
Explanation:
Cancer is a disease that result due unregulated cell divison.There are many tumor suppressor protein present in our body such as retinoblastoma tumor suppressor protein,p53 protein.
These tumor suppressor protein helps to carry out cell divison in a regulated fashion and send signal for division only to that cell that have undamaged DNA.
Mutation in the gene encoding tumor suppressor protein leads to development of cancer.
Answer:
Water is collected to compress carbon dioxide gas and pass it over rocks and soil of Mars.
Explanation:
To compress carbon dioxide gas and pass it over rocks and soil of Mars. The gas dissolves and some of the water locked up in the soil clean water which can be collected and stored. There is water present under the surface and present on the surface in the form of ice. Yes, we would be able to make use of that water. Yes, we can produce more water which is present in the air in vapor form. No, mars have very limited water and water in vaporize form which can be turn into liquid form.
