Red has the longest wavelength
Answer:
A population or group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring but do not produce viable, fertile offspring with members of other such groups
Explanation:
I used my bio textbook for this but basically only organisms in a group is a population and they can't produce offspring that survive or reproduce unless they are in the same population or populations. Think of like how a liger is a cross of a tiger and a lion and can't reproduce because its not fertile and its from two different species but a lion and a lion can produce a living offspring that can reproduce.
The number of feet the track star ran is 4921.26 feet
<h3>Conversion scale </h3>
We can convert meter to feet by using the following conversion scale:
0.3048 meter = 1 feet
<h3>How to cconvert 1500 meters to feet</h3>
The following data were obtained from the question:
- Distance (in meter) = 1500 meter
- Distance (in feet) =?
We can convert 1500 meter to feet as illustrated below:
0.3048 meter = 1 feet
Therefore,
1500 meter = (1500 meter × 1 feet) / 0.3048 meter
1500 meter = 4921.26 feet
Thus, 1500 meter is equivalent to 4921.26 feet

Answer:
Electron geometry- Tetrahedral
Molecular geometry- Bent
Bond angle- <<109.5°
Explanation:
According to the Valence Shell Electron Pair Repulsion (VSEPR) Theory, the shape of a molecule depends on the number of electron pairs present bon the central atom of the molecule. The electron pairs orient themselves as far apart in space as possible to minimize repulsion between electron pairs.
However, the repulsion between all electron pairs is not the same. Lone pairs cause more repulsion around the central atom than bond pairs. Hence lone pairs tend to distort the molecular structure away from that predicted on the basis of Valence Shell Electron Pair Repulsion Theory.
Considering XY2Z2, there are four electron domains, two bond pairs with bonding groups at 180° apart and two lone pairs. Based on VSEPR theory, a tetrahedral shape is expected with a bond angle of about 109°.
The presence of two lone pairs distorts the observed molecular geometry to a bent shape with bond angle <<109°, hence the answer above.
