That is all up to ones opinion no one really knows because no one that is living now was alive then all we can go by is secondary sources to let us know
Answer:
Do you want a ligit answer or...
Explanation:
i will answer this, but youre gonna be scared if you ask me to do it.
Well, plants have a vascular system whereas animals have a circulatory system. They both utilize tube structures that transport water and nutrients to the cells and different parts of the organism. Plants have xylem and phloem and animals have veins and arteries. An animal's circulatory system is driven by a pump, via the heart. A plant's vascular system is driven simply by gravity and the many useful properties of water. Plants have water-based solutions within their vascular systems and animals have mainly white and red blood cells within their circulatory systems.
Answer:
Studies revealed that glucose binds with the RBC membrane and intracellular proteins and increases membrane rigidity. The thing is that the concentration of glucose in the solution used is less than compared to the concentration of the same inside RBC and the cells swell up due to endometriosis.
CORRECT ANSWERS: “Eye color is controlled by many genes” and “Eye color has a polygenic inheritance pattern”
***These two answer choices are actually saying the same thing. (poly = many, so polygenic just means a trait is controlled by many genes) These are the best answers because traits that are controlled by several genes have many different phenotypes (traits) that can result (ex: blue eyes, green eyes, brown eyes, hazel eyes...etc).
WRONG ANSWERS: “Eye color is controlled by only one pair of genes”
***The trait is most likely controlled by more than one pair of genes because there are three different phenotypes discussed in the problem. There are inheritance patterns where one gene can cause three phenotypes (complete dominance and incomplete dominance), but these produce a combination of the traits (brown AND blue eyes...doesn’t make much sense) or a mix of the traits (whatever color brown mixed with blue gives you...still probably not green). Anyways, it’s a feasible answer but definitely not the BEST.
“Eye color is not an inherited trait”
***All traits are determined by the genetic code we inherit from our parents. The way our cellular mechanisms express of those traits can vary and be determined by environmental factors, but this is still by far the least accurate statement.
“Eye color is inherited from only one parent”
***For any given gene we receive one allele (copy of that gene) from each parent. Therefore, all of our traits are inherited from both parents. Again, the expression of those traits varied based on patterns of inheritance, environmental factors...etc, but this is another very poor answer choice.
