Answer:
The correct answer is -
1. due to the fact that maize is a monoecious crop that has male and female flowers in separate parts of the same plant that distributed pollen by the wind to other female parts of another maize plant.
2. Once silks are visible, they may already be contaminated with foreign pollen, so it is vital that ears shots are bagged before the emergence of silks.
3. If silks have emerged before bagging which means they are already been contaminated with other pollen and which will affect the process of hand pollination and have other varieties than desired.
Geomagnetic reversals __________. Group of answer choices Provide strong evidence for sea floor spreading Reveal that polar wandering may have occurred. Were discovered by the Deep Sea Drilling Project Confirmed the existence of subduction zones Cause the movement of plates
Answer:
The answer is "Provide strong evidence for seafloor spreading".
Explanation:
The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.
A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.
In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.
The particular name of an igneous rocks consisting of minerals is best determined using the chart in the lab book and noting:____.
(a) the presence of quartz and one other mineral.
(b) the presence of vesicles (gas pockets) in proportion with the presence of the mineral quartz.
(c) the relative color (light, intermediate, or dark) and the relative size of the minerals (phaneritic/aphanitic).
(d) whether the minerals present are metallic or non-metallic and then determining the streak on each mineral present.
Answer:
C, the relative color
Explanation:
Color indicates the composition of a rock or mineral. A felsic composition is indicated by light colors such as white or pink. Intermediate rocks or minerals have a medium color such as gray or an equal part of dark and light colored minerals . Mafic or ultramafic rocks or minerals are dark colored such as black or brown however they might also contain light colored minerals within them.

Which of the following does NOT negatively affect groundwater? Development has caused rainwater to drain into sewers instead of into aquifers. Runoff from household and agricultural chemicals filters into groundwater. Increased water consumption by humans depletes aquifers. Humans are utilizing groundwater to generate electricity.
Answer:
Humans using water to generate electricity does not negatively affect groundwater.
Explanation:
Rainwater, which is mostly fresh, drains into sewers most of the time of course. They are abundant in many towns, cities, etc. As a result, rainwater is not utilized enough, as it goes to waste when blending in with dirty sewer water. This leads to rainwater not draining into aquifers, And with the worlds population increased rapidly by the minute, consumption increases, leading to the water contained within aquifers to decrease in amount. Runoff from things such as pesticides and fertilizers is also a major issue that harms groundwater. As rain approaches, these chemicals can seep through dirt and soil, eventually going as far as to reach the groundwater underneath the surface, contaminating it. And humans utilizing water to generate electricity is more of a benefit to the environment. It is another effective way to get power, and is an alternative to fossil fuels. And using groundwater as a power source does not really affect the groundwater itself, so this is why the last option is correct.

2/5/g + 3h - 6 when g = 10 and h =6
Answer:
18.04
Explanation:
2/5/g + 3h - 6 when g = 10 and h =6
You can simplify that to 2 ÷ 5 ÷ 10 + 3 × 6
Then you follow PEMDAS
First you do 2 divided by 5 which equals 0.4
So now you have 0.4 ÷ 10 + 3 × 6
Now you divided 0.4 by 10 which is 0.04
0.04 + 3 × 6
According to PEMDAS now you do 3 times 6 which is 18
Finally 0.04 + 18 = 18.04

Imagine that you are standing on a beach but cannot swim. Your friend encourages you to walk into the surf zone created by incoming deep water waves that a wavelength of 30 meters. Would it be safe to walk out to where the waves are breaking?
Answer:
Explanation:
The water depth in the surf zone is between 5 to 10 meters deep and with a wavelength of 30 meters, the speed of the wave is considerably fast such that control for safety may be difficult
Also the speed of the wave is directly related to the depth of the water which means that where the wave described above is fast as well as the rip current, also the water depth is expected to be considerable for a non swimmer
It is best to seek for sign post regarding safe areas and do not go into the water where there are no lifeguards or marked safe zones.

Which statement best describes the difference of the mean of the two data sets?
A.
It is equal to about 0.5 times the mean absolute deviation of either data set.
B.
It is equal to about 1 times the mean absolute deviation of either data set.
C.
It is equal to about 1.5 times the mean absolute deviation of either data set.
D.
It is equal to about 2 times the mean absolute deviation of either data set.
Answer:
B.) It is equal to about 1 times the mean absolute deviation of either data set.
Explanation:
Given the scores :
Williams :
89,97, 78, 81, 91
Andre :
90, 74, 73, 87, 82
The mean scores :
Mean = ΣX / n
William's mean score = 436 / 5 = 87.2
Mean absolute deviation :
[|89-87.2| + |97-87.2| + |78-87.2| +|81-87.2| + |91-87.2|] / 5
William's mean absolute deviation = 6.16
Andre's mean score = 406 / 5 = 81.2
Andre's mean absolute deviation =
[|90-81.2| + |74-81.2| + |73-81.2| +|87-81.2| + |82-81.2|] / 5 = 6.16
Difference of the mean = 87.2 - 81.2 = 6
Mean absolute deviation of each dataset = 6.16
The closest relationship between the mean difference and the mean absolute deviation is :
Mean difference is about 1 times the mean absolute deviation
