Answer:
Two Identical DNA molecule each having one new strand and one old strand
Megaphylls and vascular tissue were required for ferns & gymnosperm evolution.
Answer:
Cheek cells are much larger than the bacteria cells. The bacteria cells are found INSIDE the cheek cells. The bacteria cells are capsule-shaped and the cheek cells are round.
Answer:
The skeletal muscle is stimulated by means of action potentials that are caused by the neuromotor plate. These action potentials are one after the other and can become cumulative once the muscle fibers pass the refractory phase of the action potential.
The refractory stage is that stage in which action potentials are not admitted, therefore where the muscle fibers do not accept stimuli to contract.
Once this refractory stage is over, more action potentials can be admitted, which would be summative and the muscle fiber would contract with greater power.
Explanation:
If a muscle is repeatedly stimulated, the contraction will be weaker or the muscle will fatigue more easily, triggering muscle failure.
If the muscle is stimulated with a longer pause between contraction and contraction, the action will be performed with more power.
Answer:
8 and 18
Explanation:
This is more math relevant question. lemme try to solve it.
given coefficients: 2 and 5
the relation between 2 and 5 = x and y
x = x ; y = 2x + (x/2)
to see possible numerical combination, we apply one by one all possible combinations in this equation.
1) 4 and 10
x= 4
y = 2x + (x/2)
= 2 x (4) + (4/2)
= 8 + 2
y = 10
this numerical combination is possible.
2) 100 and 250
x = 100
y = (2 x 100) + (100/2)
= 200 + 50
y = 250
This numerical combination is also possible.
4) 40 and 100
x = 40
y = (2 x 40) + (40/2)
= 80 + 20
y = 100
Given possible combination 40 and 100 is right.
3) 8 and 18
x = 8
y = (2 x 8) + (8/2)
= 16 + 4
y = 20
so, here given possible combination, 8 and 18 is not right. The right combination will form 8 and 20.
