Explanation:
G A T and C are all bits of DNA (deoxyribonucleic acid)
G stands for Guanine A stands for Adenine C stands for Cytosine and T stands for Thymine, when Guanine is in the DNA it always pairs with Cytosine creating G-C and the same is for Thymine and Adenine, when they are sequenced in such a way it just shows how the DNA is placed.
Sneezing is the method some viruses spread (normally flu ones). When you are infected, and you sneeze, the viruses a dispersed in the air and the person that breathes he infected air might get infected.
Hope it helped,
Happy homework/ study/ exam!
Answer;
Transport substances throughout an organism.
The cytoplasm in a single celled organism and the circulatory system in a human both transports substances throughout an organism.
Explanation;
Circulatory system carries blood to the cells of the body to distribute oxygen and nutrients and pick up cell wastes. It consists of the heart, blood vessels and the blood.
Cytoplasm in a single cell helps in the transport of materials such as nutrients, through out the cell.
At the end of meiosis, there are FOUR cells with HALF the amount of DNA.
Meiosis is a kind of cell division that produces genetically different daughter cells. Unlike mitosis, which produces genetically identical cells, meiosis goes through 2 divisions that leads to 4 daughter cells.
In meiosis, the parent cell first duplicates all its genetic material, just like what they do in mitosis. Then it divides, leading 2 genetically identical daughter cells. Mitosis ends here, but in meiosis, the 2 cells divides themselves again, but without duplicating their DNA. This leads to the 4 daughter cells with only half of the number of chromosomes.
We call these cells haploid. They're usually common in gametes. For example, a normal body cell in human has 46 chromosome, but in the cells after meiosis, they only have 23.
Answer:
The answer is B - Tap water can be found in the natural environment, but what the lab technician is testing is if there is lead in the water. This part is not related to biology therefore making B the answer.
Explanation:
Biology is the study of living organisms and life.
Every other answer is related to Biology.
A - A vitamin that helps with vision - this will affect the human vision to become better after taking it; this relates to biology because it involves the interaction of humans and the human body system.
C - Change of environment - this deals with the bird's environment and how they live and breed, which is in biology
D - Growing coffee to reduce harm to the rainforest - this deals with biology because it is taking about the environment and how certain changes will affect how it will thrive.
E - DNA - this is involved in human and other organism's systems and is related to biology.
