Answer:
The answer is B because its just your total distance so for your to get your displacement you would add the two distance together then that answer would be you displacement
It has to be C. Vascular bundles arranged in a ring. This is my chosen answer because only monocots have fibrous roots, but dicots have one main root called a taproot. Monocots have floral parts in multiples of three, but dicots have four or five. Monocots have parallel veins in leaves but dicots have branching veins. So the answer is C. Vascular bundles arranged in a ring. Hope this helps.
Answer:A particle has zero velocity initially (i.e., at time
t=0
t=0
) and its acceleration at
t
t
seconds is
a(t)=72t−4
t
3
a(t)=72t−4t3
meters-per-second per second. During the time interval
[5,8]
[5,8]
seconds find the average acceleration and the average speed of the particle. I got the average acceleration by taking the integral and then plugging that into
f(8)−f(5)/8−5
f(8)−f(5)/8−5
but I have tried working through the average speed and I can't find the answer for that one.
Explanation:
Answer:
The correct answer is - the placenta, the site of exchange of materials between the mother and the fetus.
Explanation:
In the given diagram there is a representation of a human embryo developing in the uterus. Different parts are numbered and the number three represents the site of exchange of materials between the mother and the fetus and this organ is called the placenta. It is the organ that develops between fetus and uterus during pregnancy that allows substances such as nutrients, to diffuse from the mother's blood to the fetus and connected by the umbilical cord.
