We do not use carbon dioxide to fuel our blood cells. It is a waste.
Arteries move blood from the heart to the rest of the body.
Veins carry the blood to the heart to be oxidized.
"D" is not correct.
"B" is not correct.
We know that veins carry blood to the heart, lungs exhale carbon dioxide.
"A" is the correct answer.
I hope this helps!

Answer;
-Zygote
When sperm and ovum unite at conception, a zygote results.
Explanation;
-Conception occurs when a sperm cell from a fertile man swims up through the vagina and into the uterus of a woman and joins with the woman's egg cell (ovum) as it travels down one of the Fallopian tubes from the ovary to the uterus.
-A zygote is the union of the sperm cell and the ovum. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo.
If the food is limited to the squirrels then that could impact how well they reproduce which could impact their numbers which therefore could impact the food source for the foxes which eat them. Fewer squirrels means the foxes will slow down on their reproductive numbers as well...they are all linked!
The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.
Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.
Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.
DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.
Both DNA and RNA are termed as the genetic molecules of life.
Answer:
50
Explanation:
A punnet square can be described as a diagram which illustrates all the possible outcomes of a cross. It is used to tell about the percentage chances for the kinds of genes being transferred to offsprings.
In order to check the percentage of red flowers we can draw a punnet square. As red flower is a recessive trait and pink flower a heterozygous trait,the punnet square shows that a cross between them will give 50 percent red flowers and 50 percent pink flowers.
