Answer:
c) Both are functions of blood, that is, to carry oxygen to the cells and also remove wastes from the body.
Explanation:
Blood is a form of connective tissue and is made up of red blood cells, white blood cells, platelets and blood plasma. The red blood cells contains a metallo-protein structure known as hemoglobin. This hemoglobin binds to the oxygen and carry them to the cells and the tissues for proper functioning of them. The waste products like carbon dioxide is carried by the blood from the body tissues to expel it out from the body.
Answer:Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics. So the trait is the manifestation of the product of a gene that is coded for by the DNA.

Please find the explanation below
Explanation:
Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.
The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.
Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
Answer:
The correct answer is d. Oxygen
Explanation:
Phytoplanktons are responsible for the fixation of approximately half of the global carbon therefore seawater has high CO2 concentration which is required by phytoplanktons to make their food.
They are the primary producers of oceans and they are responsible to support the food chain of oceans. Factors that can limit their growth are mainly sunlight and nutrients like phosphorus, nitrogen, etc.
As phytoplanktons are photosynthetic they release oxygen itself as a byproduct therefore oxygen is not a limiting factor to phytoplanktons. So the right answer is d.
