Answer:
The correct answer is - mitochondria lack ribosomes like prokaryotes.
Explanation:
The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.
This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.
ANSWER : C
Marine water quality can does not associate with deforestation because it concern with aquatic elements.
Mark as brainliest.
The answer is fungi
Fungi or fungus is a group of eukaryotic organism. Fungi member is mostly known as the mushroom.
It is a heterotroph so it won't have chlorophyll. The reproductive organ of fungi would be spore. It cells will be grown into a long threadlike fiber called hyphae.
Answer:
We ought to get up. Nobody should go to school fear or worry about the bully waiting at school or at the bus stop to tell you what to do every day. People do not want to be harmful and disturbed. Bully only lives every day by pressure on children. Children probably didn't go to school and do home school they didn't want to do. What that means, can't teachers or friends with those children who do not want to go to home school. Bully could result in school shots or other suicidal children as a result of the bully they've been hurt. You should not let anyone suffer and watch how someone else places him or her every day in physical or psychological pain.
Explanation:
Answer:
The mass number (symbol A, from the German word Atomgewicht [atomic weight]),[1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. Since protons and neutrons are both baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. Hence, the difference between the mass number and the atomic number Z gives the number of neutrons (N) in a given nucleus: N = A − Z.[2]
The mass number is written either after the element name or as a superscript to the left of an element's symbol. For example, the most common isotope of carbon is carbon-12, or 12
C
, which has 6 protons and 6 neutrons. The full isotope symbol would also have the atomic number (Z) as a subscript to the left of the element symbol directly below the mass number: 12
6C
