The given question is incomplete as options are not provided, however the options are as follows:
A. a large surface area-to-volume ratio
B. ability to form stacks known as rouleaux
C. a convex shape allowing for more efficient transport of oxygen
D. ability to bend and flex when entering capillaries
Answer:
The correct answer is - option C.
Explanation:
RBC cells are biconcave in the shape it is form shape of dub bell in general. These cells are small, round. The biconcave shape of the blood cells helps in the flow of the blood easily and these cells have no nucleus like other cells to have high amount of hemoglobin that is a pigment that carry oxygen and other gases for easy gaseous exchange.
Due to their flexible biconcave shape they can bend and flex accordingly during entering capillaries. The shape of the RBC helps in making stacks and large surface to area ratio.
Thus, the correct answer is - option C.
Answer:
3215 F would be the platinum melting point.
it boiling point is 6917 F.
Explanation:
There is not much to explain other then heat melts metals when high enough, I know this because I own a forge and platinum is one thing I use for melting.

Answer: Mechanical Isolation
Explanation:
Mechanical isolation is a type of barrier that prevents the species that are closely related from mating with each other.
It is used in case of plants and animals(here beetles) in which the without compatible sex organs individual of different species will not be able to mate and produce offspring.
Thus, the correct answer is option C
Answer:
Explanation:
the advantages include:
disease and drought resistant crops that require fewer environmental resources for them to grow
higher yields harvested as the crops are not attacked by pests resulting in humans receiving more food as well as generating more money from the trading of their crops
increased supply of food at a cheaper life and the crops could have a longer shelf life
crops bound to be healthy as they ae not constantly treated by pesticides that could harm people
reduce the use of pesticides that might be a great move for the betterment of the food supply
they reduce the use of toxins that could harm the environment as well as the animals and people
disadvantages
unexpected or harmful genetic changes that could result in humans health being threatened
the process of genetically modifying the crops is quite expensive
due to the plants becoming pest resistant the pests are bound to have no food hence could die leading to some helpful pests such as beetles or ladybugs that actually benefit the environment going extinct
the production of genetically modified crops results in the disruption of biodiversity as you are favouring one specific organism hence resulting in the disruption of the natural gene flow
the crops are modified hence biotech foods may be a threat to the human health
