Answer:
Blue eyes is a recessive trait
Explanation:
Recessive traits show in 25% of the offspring, but they skip the first generation. This means that the 25% only shows up in the second generation unless two recessive traits are put together. A likely combination is that both of the parents had Bb, which you can put into a punnet square to visualize.
B b
B BB Bb
b Bb bb90
Painful menstrual flow (cramps) is dysmenorrhea.
—————

An INHIBITORY Signal is sent between neurons when (A)Na+ rushes into the neuron.
Explanation:
- When one spot of membrane supports an action potential, lots of \text {Na}^+Na+start text, N, a, end text, start superscript, plus, end superscript ions hurry into the cell by that spot.
- These ions radiated out sideways into the cell and can depolarize a nearby spot of membrane, stimulating the hole of voltage-gated sodium channels and causing the nearby spot to support its action potential.
- The action potential can only move in one direction – from the cell body towards the axon terminal – because a spot of membrane that has just experienced one action potential is in a “refractory period” and cannot withstand another.
The correct answer is option D
The main cause of global warming is the green house gases that contributes more towards global warming.
The carbon dioxide produced from the transportation is the main green house gas. Transportation being the major source of carbon dioxide contributes towards global warming.
Reducing the amount of green house gases will help in the reduction of the global warming.
Answer:
ATP & ADP are nucleic acids.
Explanation:
ATP and ADP are macromolecules of nucleic acids as they are made up of structures similar to DNA.
An ADP molecule is made up of two phosphate groups, a sugar backbone (ribose) and the nucleotide adenine.
An ATP molecule is made up of sugar backbone, three phosphate groups and the nucleotide adenine.
Hence, Both the structures are similar to DNA and RNA. As the structures contain nucleotides hence ATP and ADP are nucleic acids macromolecules.
