i guess the answer is B.transport oxygen through the blood
Answer:
Her full blood type genotype is Dd.
Explanation:
Rh (Rhesus) factor is a type of protein found on the outside of red blood cells. It is genetically inherited. An individual that has this protein is Rh-positive, and the one that doesn't is Rh-negative. The Rh-positive gene is dominant, while the Rh-negative gene is recessive. This means that a person must inherit at least one dominant (D) allele from their parents in order to be Rh-positive.
If Dr. Mrs. Brown is Rh-positive, and her father is Rh-negative, her mother must be Rh-positive (DD or Dd), as well. Her father has two recessive alleles (dd), which means that Dr. Mrs. Brown must have one recessive allele. Since she is Rh-positive, she must have one dominant allele. This makes her genotype Dd.
Answer:
mitosis -> cell differentiation -> stem cells
Explanation:
Zygote Definition: a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
Mitosis: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Cell Differentiation Definition: Cellular differentiation, or simply cell differentiation, is the process through which a cell undergoes changes in gene expression to become a more specific type of cell.
Stem Cell Definition: an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.
-------------------------------------------------------------------------------------------------------
Since cell differentiation can not come before mitosis so the 2nd option is wrong. Stem cells can not turn into zygote cell option 1 is wrong. Cell differentiation would come before stem cells since stem cells are a final product, the 4th option is wrong. So I think option 3 is correct.
The correct answer is that it helps society to make logical decisions.
Science in a manner revolutionizes the pace of the society by leaning towards the technological advancements. In a manner, science also offers another perspective to various things in life comprising ideas and theories, which are dubious to various individuals. Hence, the correct answer is that science helps society to make logical decisions.
Answer:
Water absorbs heat by breaking hydrogen bonds.
Explanation:
Specific heat is the amount of heat that must be absorbed or lost for 1 gram of that substance to change its temperature by 1 degree. As someone works out, their body releases sweat to keep their body from overheating. Specific heat it mentions that hydrogen bonds between water molecules require heat to form and break, which is what happens when we sweat.
